Qingdao Conqinphi Environmental Technology Group Co., Ltd., a leading manufacturer established in 2015 with a factory area of 10,000–30,000 m² and an annual export value of US$10–50 million, proudly presents our MVR Forced Circulation Evaporator specifically designed for solvent recovery in the chemical industry. This advanced system integrates mechanical vapor recompression technology with forced circulation design, delivering exceptional energy efficiency and high recovery rates for organic solvents such as methanol, ethanol, acetone, and more. Whether you need to reduce operating costs or meet strict environmental regulations, our evaporator offers a reliable, scalable solution backed by a team of 201–300 skilled professionals and multiple international certifications.
Key Features & Benefits
- Energy Saving: MVR technology recycles latent heat from vapor, reducing energy consumption by up to 60–80% compared to traditional multi-effect evaporators.
- Forced Circulation Design: Prevents scaling and fouling in high-viscosity or fouling-prone solvent mixtures, ensuring stable long-term operation.
- High Recovery Purity: Customizable separation efficiency – typically 95%–99%+ purity of recovered solvent depending on feed composition.
- Wide Solvent Compatibility: Suitable for low-boiling, azeotropic, and heat-sensitive solvents commonly used in chemical synthesis, pharmaceutical intermediates, and fine chemicals.
- Automated Control: PLC-based system with touchscreen HMI monitors temperature, pressure, flow rate, and concentration in real time, enabling one-button start/stop and remote monitoring.
- Compact Footprint: Modular skid-mounted design reduces installation time and floor space requirements.

How It Works
The forced circulation evaporator uses a circulation pump to maintain high liquid velocity inside the heat exchanger tubes, minimizing scaling. The vapor generated is compressed by the MVR compressor, raising its temperature and pressure, then reintroduced into the heating chamber as a heat source. This closed-loop system dramatically reduces steam consumption and cooling water requirements, making it ideal for continuous solvent recovery processes in chemical plants.

Frequently Asked Questions (FAQ)
-
Q: What types of solvents can this evaporator handle?
A: It is suitable for a wide range of organic solvents including methanol, ethanol, acetone, ethyl acetate, toluene, xylene, and many others. For highly corrosive or high-boiling solvents, we can select appropriate materials and process parameters. -
Q: What is the typical energy savings compared to a multi-effect evaporator?
A: The MVR system typically saves 60–80% of steam consumption. Actual savings depend on the boiling point elevation and required temperature lift. -
Q: Can I recover solvents with azeotropic mixtures?
A: Yes, we can design the system with side-draw or additional columns to handle azeotropic mixtures. Our engineers will analyze your feed composition and recommend the best configuration. -
Q: What is the minimum and maximum capacity you offer?
A: Standard capacities range from 500 L/h to 50,000 L/h. Larger capacities are available upon request for industrial-scale projects. -
Q: How long does it take to install and commission?
A: For skid-mounted units, installation takes about 1–2 weeks on-site. Commissioning and training usually require another 3–5 days, depending on complexity. -
Q: Do you provide remote monitoring and control?
A: Yes, our PLC system supports remote access via Ethernet/4G. We can also integrate with your existing DCS or SCADA system. -
Q: What after-sales support do you offer?
A: We provide free documentation, 12-month warranty, lifetime technical support, and fast spare parts delivery from our Qingdao warehouse. -
Q: Can I get a sample test before purchasing?
A: Absolutely. We offer free lab-scale testing at our factory in Qingdao. For special solvents, we can also arrange on-site pilot testing.
