    Other articles where Vapour compression distillation is discussed: water supply system: Thermal processes: In the vapour-compression system, heat is provided by the compression of vapour rather than by direct heat input from a boiler. When the vapour is rapidly compressed, its temperature rises. Some of the compressed and heated vapour is then recycled through a series of tubes passing . lower end of the adapter well into the mouth of the receiver. A distilling assembly must have an opening to the atmosphere to avoid developing a dangerously high pressure within the system when heat is applied. Key Point: When conducting a distillation, the vapor should be richer in the lower boiling component than what you started with.

    Pharmaceutical Vapor Compression Distillation (VCD), improperly known as thermocompression or such as mechanical vapor recompression (MVR) or mechanical vapor compression (MVC) distillation, too, is the main way to produce WFI Water For Injection and grade waters for pharmaceutical use. Our vapor compression distillers use only about half the energy of multi-effect distillation, providing you high purity water at a significant cost savings. Aqua-Chem VC distillers have set the standard for reducing maintenance costs and downtime while increasing operating life—with units that continue to provide excellent service after more.

    This investigates a high-efficiency mechanical vapor-compression distillation system that employs an improved water flow arrangement. Greater efficiency of the vapor compression system is achieved by connecting multiple evaporators in series, rather than the traditional parallel s: 1.

Final report on life testing of the vapor compression distillation/urine processing assembly (VCD/UPA) at the Marshall Space Flight Center ( to ). [P O Wieland; George C. Marshall Space Flight Center.] -- Wastewater and urine generated on the International Space Station will be processed to recover pure water using vapor compression distillation (VCD).

Vapor Compression Distillation (VCD) is the chosen technology for urine processing aboard the International Space Station (ISS). Development and life testing over the past several years have brought to the forefront problems and solutions for the VCD by: 4.

An Update of the Readiness of Vapor Compression Distillation for Spacecraft Wastewater Processing Vapor Compression Distillation technology has proved its readiness as a spacecraft wastewater processor as evidenced by selection of this technology for the Urine Processor Assembly aboard Space Station by: 4.

For the VCD experiment, de-ionized water containing some salts will be used instead of urine. The water will be fed into the distillation assembly's rotating drum, spinning at revolutions per minute, where it will form a thin film that will coat the walls of the drum.

The process Vapour compression is a distillation process, where evapora- tion of sea or brackish water is obtained by the application of heat delivered by compressed vapour. Mechanical vapor compression distillation of saline water is a process in which mechanical energy is used as the main driving force.

It is basically a heat pump process that pumps heat from a low-temperature reservoir to a higher temperature reservoir, just. The Final Report consists of two stand-alone documents. This document is Volume II.

It describes the work performed in expert fault diagnostic development for the Vapor Compression Distillation Subsystem. The Final Report is submitted to the National Aeronautics and Space.

The vapor compressor receives the low-pressure steam from the fourth VTE effect at with 8 super- heat and increases its temperature to superheated steam, which is VAPOR COMPRESSION DISTILLATION then desuperheated to The boiler steam is.

Incoming water (influent) enters the system and runs through two heat exchangers which transfer heat to the influent from the outgoing pure water (distillate) and grey water (concentrate).

The mechanical vapor compression (MVC) desalination system is based on distillation of seawater. The system is basically a heat exchanger that is an evaporator/condenser.

The heat required to evaporate water which flows on one side of a heat transfer surface is supplied through the simultaneous condensation of the distillate-producing vapor on. (Page 1) Distillation is one of the most extensively used operations in the chemical process industries (CPI).

It is a highly energy-intensive unit operation, and continuously rising energy costs make it imperative to look for ways to reduce energy requirements. Some energy-saving configurations can increase capital investment costs, so the benefits need to be weighed carefully. The Mechanical Vapor Compression (MVC) distillation is inherently the most thermodynamically efficient process of single-purpose thermal desalination plants.

The thermodynamic efficiency is derived from the application of the "heat pump" principle by a large. BRAM-COR VAPOR COMPRESSION DISTILLATION PROCESS.
