Vacuum booster for drying application

Drying is a process of removal of a liquid from a solid mixture by thermal means. Under this article, we shall not consider mechanical methods, such as filtration, centrifuging, pressing, etc. of liquid removal from solids. Various drying process & techniques are extensively used in the various Process industry, Pharmaceutical industry, Food processing  ndustry, Dye & Chemical industry, Perfumes & Permitted Food additive industry etc primarily to achieve one or more of the following,

Vacuum booster for distillation process

Distillation at reduced pressures is a widely used process in the chemical industry, specially used in extraction / purification of essential oils, deodorisation of Vanaspati / Vegetable Oils and purification & drying of chemicals. The advantages of low-pressure distillation process over Atmospheric pressure distillation are as under:

Vacuum booster for chemical process

Mechanical vacuum boosters are dry pumps that meet most of the ideal vacuum pump requirements. They work on positive displacement principle and are used to boost the performance of water ring / oil ring / rotating vane / piston pumps and steam or water ejectors.They are used in combination with any one of the above mentioned pumps, to overcome their limitations. Vacuum boosters pumps offer very desirable characteristics, which make them the most cost effective and power efficient option.

MVR writeup 2016

Industrial units are facing multiple problems for survival such as in effluent water discharge. It could be very difficult to get process water abundantly as water sources are limited and it is very essential for industries to recover as much water as possible for recycling. Many industries are considering “ZERO OR NEAR ZERO LIQUID DISCHARGE.

Field Service Trouble Shooting Manual

Blowers and vacuum boosters fail for a reason. The most common causes of failure include operating beyond the unit’s limits of speed, pressure, compression ratios, temperature and horsepower.
Additional failure causes are from installation mistakes, and high operating temperatures.

Vapor Recompression to Recover Low Pressure Waste Steam

Increasing energy cost and pressures on imporoving process efficiency are forcing process engineers to minimize wasteful losses. Efforts are continually being made to minmize all such looses.

Vacuum Pumps , Common Problems and Trouble Shooting

Vacuum Pumps and Systems are one of the widely used equipment in process plants. It is very important to correctly size and select the vacuum pump as it is to lay down the right specifications. Understanding the fundamentals of vacuum as well as the system and its integration would enable the operators to deal with the day to day problems, which are inevitable.

Screw Pumps – FAQ’s

Q : What do you mean by HYBRID SCREW DESIGN? In what way it is diferent from the variable pitch screw manufactured by other Screw Pump Manufacturers?

Ans: Hybrid Screw design ofer advantages both single pitch and variable pitch. Hybrid screw was designed with two constant pitches and one variable pitch.
