Vapor compression distillation (VC) produces WFI using distillation, where equipment process distills the water using phase changes, like evaporation, and entrainment separation.
In the VC process, evaporating the water produces vapor through compression to increase the pressure saturation and temperature. By transferring its excess heat to infeed water in a heat exchanger, this compressed vapor condenses to produce WFI. Water moves through VC distillation with the following steps:
Distillation through VC is a more energy-efficient process than others because of its inherent ability to reuse excess heat in the early steps. Latent heat produced during the evaporation process returns to the pre-heater and demister, where it can help power these processes. Entrained water droplets return to the feed water to begin the process again, requiring less water and energy to become distillate.
When considering using VC over other water distillation methods, you can experience many features that will enhance your distillation uses, including:
The MECO VC features the GII Centurbo™ Compressor, which is patented technology. This directly driven variable-speed compressor eliminates the need for maintenance and additional parts while reducing inefficiencies accompanying flex couplings, gear transmissions and belt drives.
With a liquid-cooled motor, the MECO VC requires the minimum amount of lubrication technology. It removes the need for a recirculating oil system with coolers, plumbing, filters, instrumentation and valves. It eliminates oil and filter changes, reducing maintenance requirements while improving reliability and efficiency for increased runtimes with fewer problems.
The energy consumption of your distiller represents the largest expenditure over its lifetime. MECO VC plants are the most energy–efficient in the industry. Given the same feed water temperature, discharge temperatures and flow rates, the steam consumption of VC distillation plants should nearly be identical and significantly less than other conventional distillation methods. However, MECO’s large surface area evaporators use less electrical power, translating to the lowest cost per thousand gallons produced.
Distilling water using VC can help increase your WFI production more efficiently and reliabily while saving you money and energy. Partnering with a solid manufacturer who understands your industry needs can help you find high-quality solutions that fit your standards and budget.
