Universal Skid Mounted Solvent Reclaiming Unit Modular Solvent Recycling Unit

This fully modular, universal Solvent Recovery System is the ultimate flexible asset for Chemical Development and Manufacturing Organizations (CDMOs), pilot plants, and multi-product chemical tolling facilities. Designed to handle a vast solvent polarity and boiling point spectrum—from volatile ethers to high-boiling NMP—it combines a versatile Wiped Film evaporator with a configurable condenser and collection train. The all-stainless, skid-mounted platform provides a single, cleanable plant capable of frequently switching between recovering ethanol from a cannabi s extract one day, stripping aceton e from a polymer the next, and drying DMF from an API intermediate after that. It is the quintessential revenue-generating tool for any organization that must rapidly, safely, and economically serve diverse client purification needs without a dedicated plant for every single solvent.

CDMOs and research pilot plants face a unique economic strain: their clients' chemistries are wildly different. One project requires heptane recovery from a polyolefin process, the next requires methanol stripping from a heat-sensitive natural product. A conventional fractionating column, with its fixed internal packing and deep liquid hold-up, is a single-solvent tool. It cannot be economically cleaned, and its high residence time destroys the heat-sensitive molecules of the next project. This forces facilities into a lose-lose situation: either invest millions in a museum of single-purpose recovery stills that sit idle for months, or painfully turn away high-margin fast-track contracts because the equipment cannot be guaranteed clean or flexible enough. The lack of a universal solvent stripping tool is a direct brake on revenue and business agility.

Our Modular Solvent Recovery System is a single, multi-purpose plant that solves this through its mechanical film design. Because a Wiped Film evaporator separates based purely on a single-stage temperature cut and has virtually zero internal hold-up (~1% of hourly feed), it is chemically agnostic and instantly cleanable. Switching from a toluen e run to an ethanol run is a matter of a 30-minute solvent flush and a nitrogen dry cycle. The PLC stores an unlimited library of client-specific recipes, ensuring an operator can recall a pharmacopoeia-grade recovery protocol with a single tap. The skid’s modular design allows the condenser, vacuum pump, and heater to be quickly reconfigured for different boiling-point solvents, making it the perfect one-machine answer for a high-mix, fast-turnaround toll processing business. It’s not just a piece of equipment; it’s a flexible capacity contract in a box.

• CDMO Operations: Providing a billable solvent recycling service to multiple pharmaceutical and biotech clients.

• Cannabi s Toll Processing: Accepting diverse crude extracts and efficiently recovering ethanol, heptane, or pentane.

• University Pilot Centers: Serving several research groups with incompatible chemistry on a single capital investment.

• Startup Scale-Up: Running initial commercial volumes while a dedicated, larger plant is being fabricated.

The client’s solvent-laden feed is connected to the skid’s feed pump. The operator selects the appropriate recipe, which sets the evaporator temperature, vacuum level, and condenser coolant flow. The Wiped Film unit creates the thin film, the solvent flashes, and the clean distillate collects in the client's return drum. Once the run is finished and the concentrate collected, the operator runs a "clean" cycle: a CIP spray, a wash-solvent recirculation, and a vacuum-assisted hot nitrogen dry-down. The system is then immediately ready for the next project with no chemical carryover.

The primary decision is the wiper technology kit: acquire a set of PTFE wipers for general food-grade use, carbon-impregnated wipers for abrasive slurries, and PEEK wipers for high-temperature solvents. This single purchase is your insurance against losing a contract due to chemical incompatibility. Match the included vacuum pump suite to the lowest boiling point solvent you expect to process, as achieving a high vacuum at the pump suction is critical for low-temperature DMF or NMP work. Finally, invest in the advanced software module for automated batch report generation and cleaning validation logs; this document trail is what allows you to invoice for a premium, fully compliant service.

1. Q: Can I really switch between completely different solvents without cross-contamination?
   A: Yes, this is the system's defining feature. The low hold-up and continuous scraping action leave very little residual liquid. A validated cleaning protocol, typically a 30-minute hot-solvent flush, returns the system to a "clean-empty-dry" state ready for the next client's run, with analytical swab data to prove it.

2. Q: What support do you provide to set up the initial customer recipes?
   A: Our process engineers work with you to develop a master recipe for each major solvent family. This includes a remote or on-site pilot test to map the exact temperature/pressure conditions and yield, followed by remote support when the first production lot is run.

3. Q: How portable is the skid?
   A: The entire system is built on a heavy-duty structural steel frame with certified lifting lugs and forklift pockets. It can be relocated by a rigging crew in a single shift. The single-point utility headers mean re-commissioning is simply a matter of bolting on the facility’s power, cooling water, and nitrogen connections.

4. Q: Is it safe to use for a variety of flammable solvents?
   A: The standard configuration is built to Class I, Division 2 standards, providing a safe, purgable enclosure and non-sparking components. For a more hazardous C1D1 environment, a fully certified upgrade package is available, complete with nitrogen-inerting interlocks and intrinsically safe field devices.
