The beginnings of ESCON in the late 90s themed around applied thermodynamics at the departments of process engineering and food technology of the Berlin Technical University, where the two co-founders ran various pilot operations.

Originally conducting factory performance analyses, heat and mass balances and process optimization for the international sugar industry, soon the focus shifted towards process design and technology supply.

ESCON has been established as a limited liability corporation (GmbH) in 2002, with the aim to provide Fractal SMB Chromatography and IEX Purification Technologies for many different industries as worldwide licensee of Amalagamated Research LLC. With over 200 projects completed and more than 80 Fractal-based systems built, including the world’s largest SMB Chromatography system (750 t molasses per day), this partnership has become quite successful.

Over the years, ESCON has expanded its activities into the fields of project management, detail engineering, financing and procurement. Our staff of widely acknowledged experts enables ESCON to offer also complementing technologies like evaporators and complete evaporator stations as well as condensing systems.

Key components and process design are developed in close cooperation with Amalgamated Research LLC , the leading research and development group in the field of separation, mixing and fluid distribution/collection technologies.

ESCON will be your partner throughout your project – starting from concept & process development stage, via engineering and interface management up to complete supply and full onsite support.

Our technologies


From the very beginning it was ESCON’s aim to provide the most efficient liquid separation technologies for customers worldwide. Therefore, ESCON chose to establish the partnership with ARi, the company who has been designing industrial scale Simulated Moving Bed (SMB) CHROMATOGRAPHY technology since the early 80s.

ARi has developed proprietary operating modes to improve SMB performance, including Coupled Loop SMB, where multiple components are separated with high purity and recovery. The use of FRACTAL technology for process intensification in ARi’s CHROMATOGRAPHY systems ensures reliable scale-up and maximizes operating efficiency.

Chromatography is a method for the separation of dissolved components in a mixture. The mixture - also "mobile phase" - carries it through a fixed bed comprising of another material called the "stationary phase" - e.g. resin, silica or other porous material. The various constituents of the mixture travel at different speeds, causing them to separate. 

The separation is based on differential partitioning between the mobile and stationary phases due to the physics of adsorption, ion exclusion and/or size exclusion. Subtle differences in a compound's characteristic result in differential retention on the stationary phase and thus affect the separation. A time-controlled draw of the leaving flows results in streams with different product concentrations.


Simulated Moving Bed (SMB) Chromatography  is the most advanced and efficient technology for the separation of multiple dissolved components and it is a continuous process. While requiring significantly less elution media than e.g. batch chromatography, SMB is guaranteeing maximum product recovery (yield) and allowing for extremely high product purities.


While multiple applications for SMB Chromatography have already been developed, established and delivered for the food, biobased chemicals, renewables and pharmaceutical industries, YOUR particular process may not be among them.

Let us explore the potentials of this powerful separation technology for your application. Together.



The use of FRACTAL fluid distribution technology in our IEX and ADSORPTION systems helps to maximize process performance and provides unique scalability. While recovering and purifying your valuable compounds is of highest importance, providing a process which protects the resources by reduced utility requirements becomes more relevant every day. The larger the systems the bigger the potential benefits with FRACTAL based systems.

Whether it is high purity battery metals like Lithium required for the increasing number of electric vehicles, fine chemicals production or polishing platform chemicals from renewable sources - multiple applications for Ion Exchange & Adsorption may have already been developed, established and delivered by ESCON.

 Wherever your focus is set on - maximum recovery, highest purity or utilities and waste reduction - we will help you to choose the best solution. Contact us and together we can explore the potentials of this powerful purification technology for your application.


Falling Film Tube EVAPORATORS provide minimum pressure loss, smallest effective temperature differences, shortest product residence time and lowest space requirement. For the food industry, processing large quantities of heat sensitive products such as milk, fruit juices and sucrose solutions, Tube Falling Film EVAPORATORS are the most appropriate option.

Additionally, applications in the chemical industry can profit from the compact design and excellent heat transfer of Falling Film Evaporators.

ESCON provides complete solutions: entire Evaporator units, computer based design of all Evaporator details, reliable Product Distributors and proven expertise - especially for applications in the sugar and starch sweetener industry. In order to minimize vapor carry-over, special attention is given to the design of Droplet Separators.

If required by the process or other constraints, ESCON also supplies special Evaporator designs including Rising Film Evaporators, Forced Circulation Evaporators and Flash Evaporators.

ESCON’s scope of supply comprises Single Evaporators or Multi Effect Installations based on detailed heat and mass balances - either on a EPS basis or as a package solution. This includes upgrading and retrofitting of existing vessels or complete stations.



In many thermal processes, vapors have to be condensed or there is a need to create a vacuum. Since its beginnings, ESCON has designed, engineered and built different types of CONDENSERS for various applications.

Condensation is the transformation of a fluid (mostly H2O) from the vapor phase into the liquid phase. This phase transformation happens at a constant pressure and temperature – the saturation point of the fluid.

In technical processes, a temperature gradient is necessary to force vapors into liquid. But for the process economy it is crucial that these required temperature gradients are as small as possible. ESCON’s condensation technologies minimize cooling water flows and electricity requirements on vacuum and cooling water pumps.

Contact or barometric Condensers are the choice when vapors from evaporation or crystallization processes have to be condensed and do not need to be re-used as process condensates. The barometric water, a source for waste heat recovery, cycles through cooling towers.

ESCON’s superior Spray Nozzles are designed to gain approach temperatures of less than 4 °C between vapor (saturated) and barometric water temperature. They can be welded or flanged into Condenser vessels to accomplish different load and capacity tasks during year-round operation (e.g. sugar beet campaign vs. thick juice campaign). Lowest electricity consumption for cooling water and vacuum pumps can be achieved, helping to minimize OPEX of the production cycle.

ESCON’s barometric Condensers can be chosen between separate single condenser vessels or condensation towers, combining different pressure zones in a one tower design. Condensing towers do not need additional steel construction and are installed on high skirts which comprise seal tanks for high and low temperature barometric waters.

If condensed vapors need to be recovered (e.g. as process water), ESCON delivers high performance Surface Condensers (tube & shell). These units can achieve extremely high vacuum and guarantee perfect process water qualities for a year-round operation.

Our Applications



molasses Desugarization & Betaine Recovery

Maximizing overall yield of valuable sugar from beet has been a strong driver for implementation of Molasses Desugarization Plants in many countries. As world leaders in this application, ESCON and ARi have developed highly efficient SMB Chromatography technology for the recovery of a high purity sucrose fraction from beet molasses and betaine as a valuable by-product.

Besides Chromatography the process typically includes pre-treatment of molasses and Evaporation of products and by-products. ESCON is providing the full scope of engineering and equipment supply.

Most Molasses Desugarization Systems worldwide have been supplied by ESCON with ARi technology – including the largest and most modern plant with 750 t per day processing capacity and a new 650 t per day plant to be commissioned in the USA in 2023.

Dilute products are concentrated in multi-effect Evaporator stations designed and built by ESCON.

Fructose Enrichment / HFS Production

ESCON is providing advanced industrial SMB Chromatography systems for fructose enrichment for the food (starch sweetener) and bio-based chemicals (renewables) industries. ESCON is using ARi’s fractal technology for maximum performance and scalability. Since installing its first SMB system for high-fructose corn syrup production in 1981, ARi technology has been used in SMB systems for corn syrup applications worldwide.

ESCON’s SMB systems supply high purity streams for the production of syrups including HFS 55, HFS 90, crystalline fructose, and dextrose.

High purity fructose syrups are also among the key precursors for bio-based chemicals and bio-based plastics. ESCON is supplying SMB chromatography systems for very high-quality feedstocks with up to 98 % fructose purity (HFS 98).

Biobased Organic Acids & Platform Chemicals

Together with ARi, ESCON has developed, pilot tested and built custom Chromatography systems for the separation of various biobased organic acids, including acetic acid, citric acid, succinic acid, lactic acid, and more. Feedstocks such as fermentation products can be separated into a high purity organic acid and an impurity stream. The organic acid can then be used as a renewable feedstock for chemical production, such as using purified lactic acid for polylactic acid (PLA) biopolymer production.

Liquid Sugar from Cane Raws

Our partner ARi has developed a process including SMB technology to produce commercial liquid sugar directly from raw cane sugar, meeting purity, color, ash, and turbidity product specifications of bulk liquid sugar buyers. This SMB process as a highly effiicient method to remove color AND ash simultaneously eliminates the energy and equipment required to produce liquid sugar through crystallization and melting.

Specialty Sugars

In cooperation with partners from a diverse range of industries custom separation processes were developed for various specialty sugar solutions. We are using Chromatography and other resin- or adsorbent-based processes to separate components in solutions containing fructose, glucose, sucrose, maltose, xylose, lactose, and other sugars.

Biomass Hydrolysate

Fuels and chemical building blocks derived from renewable sources remain a strong focus area for global research and development in the process and chemical industries. Partnering with numerous customers, our technology licensor has developed extensive experience in separating various components from biomass hydrolysates using Chromatography and other resin-based or adsorbent-based processes. In this industry, SMB Chromatography is typically used to produce high purity streams containing various sugars, such as mannose, xylose, glucose, etc. These sugars may then either be fermented or reacted to generate a wide array of products. ARi’s separation technology has also been used to target specialty non-sugar components in biomass extract, such as inulin.

Inorganic Separations

In cooperation with ARi, ESCON is developing and installing systems to perform various inorganic separations, including acid recovery from reactor product streams in the mining and biotechnology industries. SMB Chromatography vessels have been constructed using stainless steel, Super Duplex, rubber-lined carbon steel, and CPVC to be resistant to acidic corrosion. Other components can be manufactured from polypropylene, stainless steel, Hastelloy, Alloy 20, or other suitable materials depending upon the chemical properties of the feed.

Battery Metals / Lithium Production

So far adsorption has been the method of choice to recover Li from brines and other sources. Together with ARi, ESCON is working on applying high performance SMB chromatography for Lithium enrichment. For recovery from salt lakes and for recyling of higher concentrated solutions.


Highly efficient industrial Ion Exchange and Adsorption systems are one of ESCON’s key technologies. Customers from a wide range of industries are relying on the unmatched performance of our Fractal-based applications.

The use of Fractal technology in our IEX systems ensures reliable scale-up and maximizes operating efficiency.

Thin Juice Softening

Many beet sugar factories still do not take advantage of the significant processing benefits to be gained from Thin Juice Softening (also: Decalcification).

Weak Acid Cation Exchange (WAC) Softening in combination with Fractal Fluid Distribution Technology represents the most modern decalcification method providing a dramatic reduction in process size. The main advantages of weak cation resin are high exchange capacity, waste-free processing without production of juice-diluting regenerant and highest possible flow rates. Regeneration uses dilute sulphuric acid followed by caustic neutralization and is extremely efficient. The regenerant is transformed into a high-quality gypsum solution which, when used in the diffuser supply water, results in excellent pulp pressing properties.

Benefits from processing thin juice using WAC softening are numerous:

  • No scale formation resulting in improved heat transfer in downstream heaters, evaporators and pans
  • Less processing downtime
  • Maintenance of steam economy and exhaust steam pressure during the entire campaign
  • Maintenance of electrical power production at the maximum level
  • Improved filterability of downstream media such as thick juice (especially from storage) and standard liquor
  • Reduced demand for gypsum (used for pulp pressing), filter aid, antiscalant, cleaning chemicals and maintenance labor
  • Reduced sugar losses in process streams
  • Improved sugar quality

So far ESCON has successfully delivered about 20 units in Europe and North America - with more being commissioned soon. Typically, the technology is supplied under an EPS contract basis.

Liquor Decolorization

ESCON Decolorization Plants allow effectively removing color bodies from filtered liquid flow streams by adsorption to an appropriate stationary ion exchange resin combined with patented ARi's Fractal technology. Strong base anion exchange resins in chloride form are used which can be easily regenerated with an alkaline brine solution.

While refinery liquor Decolorization is the main application in the sugar industry, other media such as thick juice, centrifugal run-offs or extract from Molasses Desugarization can also be Decolorized – however the high feed colors require some special attention.

The unique Fractal technology also represents the cutting edge solution for Decolorization tasks in liquid sugar plants, in the beverage industry and in breweries.

Economic: Operation with double regenerant use and brine recovery through a Nanofiltration (NF) system facilitates significantly reduced effluent formation and low utility consumption. Reverse Osmosis (RO) and further complementing technologies provide the opportunity for zero liquid discharge in our Decolorization plants.

The process intensification achieved by the introduction of Fractal technology improves resin utilization and overall efficiency.

ESCON’s scope of supply comprises complete stations including proven expertise and on-site services.

Lithium Adsorption

ESCON's Adsorption Equipment Technology for Direct Lithium Extraction (DLE) will help to overcome the negative environmental impact caused by evaporation ponds and other harmful lithium harvesting technologies. Adsorption technologies allow to return the transport water back into the soil where it belongs, protecting the unique ecosystem in the area of the salt lakes and elsewhere.

Large flow streams with relatively low concentrations of the target component like e.g. lithium require reliable and robust equipment that performs at any scale and operating condition.

ESCON is supplying Adsorption Columns of different sizes for various customers in the lithium market – from pilot testing to large scale technical plants operated in severe environments.

The use of ESCON’s columns with ARi’s Fractal fluid distribution and collection systems have proven to increase recovery and reduce elution water requirements due to maximized adsorbent utilization. Contact us for more information.


ESCON's Ion Exchange Technology is successfully used for removal of divalent cations from lithium solutions. High process efficiency at low utility demand are achived by applying Fractal technology and process know-how. 

Fruit Juice Decolorization

Decolorization of fruit juice concentrates has been a challenge due to extremely high viscosities. The use of Fractal technology in combination with special adsorption resins allows to process concentrates in the same installation as more dilute products for improved overall economics.

Electronic Grade Chemicals

Purification of fine & specialty chemicals to electronic grade puts highest requirements to equipment technology as slightest impurities will cause products to be rejected. By supplying numerous units for ultrapure chemicals production, ESCON has gained significant expertise in this field.
