Continuous Devolatilization

Devolatilization and Solvent Recovery Systems

Whether through thermal or mechanical treatment, Bepex offers a broad range of equipment to meet your devolatilization or solvent recovery needs. Plus, our proprietary designs provide efficiency, cost, and maintenance benefits that you won’t find anywhere else.

Why choose Bepex?

At Bepex, we’re the industry experts on continuous material transformation processes. Solvent recovery and removal of other volatiles is key to many production processes. Our wide range of technologies make selecting the right equipment simpler and more efficient. With Bepex, solvent removal to low PPM or PPB levels is possible, predictable, and profitable.

Broad Product Line

Bepex offers a wide range of solvent recovery equipment based on feed properties, product requirements, temperature limitations, and residence times. Plus we focus on gaining the highest efficiency with the lowest equipment footprint – resulting in reduced operating and cap ex costs.

Precise Control

Proprietary designs, strict time and temperature operation, and adjustable components help achieve near complete volatile removal and low PPM or PPB moisture levels.

Design Expertise

Our experts work with you in our Process Development Center to design, test, and quantify your devolatilization design. Our total systems approach focuses both on solvent removal and recovery and the up-steam and downstream system requirements needed to optimize your entire process.

Process Development

Step 01


All new inquiries begin with a feasibility study. These studies aim to provide preliminary insights into the viability of a commercial process. Using as little as 100 grams of material, we can begin early process design, develop plans for pilot-testing and/or confirmation, and begin providing early economic estimates. Our experience across our wide range of technologies gives us a unique ability to provide quick feedback on the feasibility of your process.

Step 02


From our learnings, we’ll begin the process development work. The primary work in this phase takes place in the form of pilot-scale testing in our Process Development Center. Our pilot tests look a bit different than what you may have experienced in the past. Each test is designed to measure the system performance and feasibility rather than that of any single machine.

Each system is custom assembled for each test. Our goal is to provide as much of a pilot-scale simulation as possible while gathering scale-up data to deliver on commercial capacities. When a certain technology proves ineffective, we’ll draw from our range of options to determine if there is a better fit. The Process Development Center is our sandbox to build, test, and revise to ensure we get every detail right.

Step 03

Budget Evaluation

With a successful pilot simulation completed, we now have everything we need to scale up and provide proposals for capital equipment with included performance guarantees.

Step 04

System Design And Build

After receipt of the purchase order, we begin with both equipment and system engineering. Each proprietary technology we sell is custom-designed and built per application. We do not have any off-the-shelf units. At this stage, your exact system begins to take shape, including auxiliary equipment, process flow diagrams, process and instrumentation diagrams, safety provisions, and more.

Step 05


After delivery and installation of your new system, Bepex will provide a mechanical check to ensure everything is placed according to plan. This is followed shortly thereafter by system commissioning. This is where our pilot-scale simulations become invaluable, as our team of application engineers, controls technicians, and sales engineers begin working with your team to successfully bring your system online.

Step 06


At this point, you’re up and running at rate, producing a quality product, but our work doesn’t stop there. 

Following commissioning, Bepex remains a reliable partner, providing quality OEM parts, immediate field service, process optimization, training, system troubleshooting, and more. We have consistently had high customer retention rates, and we believe it is due in large part to our comprehensive approach to serving our customers long after the original sale.
