Process Vacuum is an integral requirement in majority of Chemical, Pharmaceutical, Fertilizer, Dairy and Food Processing, Steel Plants and a lot of other continuous Process Industries.
Industrial Process Vacuum is used in a lot of applications across the industries some of which are mentioned below
- Drying
- Distillation
- Sterilization
- Degassing
- Crystallization etc
Selection of the right equipment for generating Vacuum across the Plant is a topic which is carefully considered and debated by Plant Managers, Design Engineers, Consultants, Process Engineers as well as Project Managers.
The key considerations being the Ultimate Vacuum required for the application, the maintenance of the equipment, Initial cost, other Utilities required as well as the Total Lifecycle Cost of the Vacuum System.
There are 4 Major Technologies which are readily used in the market for generating process vacuum namely Ejectors, Dry Vacuum Pumps, Liquid Ring Vacuum Pumps and Oil Sealed Vacuum Pumps
Each of these system/pump has its own advantages as well as disadvantages the major ones are listed below

Dry Vacuum System and Dry Vacuum Pumps are widely used in the industry due to their robust design and construction. Moreover Dry Vacuum Pumps do not largely use any additional utilities as in most of the cases and are environmentally safe and intrinsically safe in their operation
However, the mean of generating vacuum should be carefully done considering the characteristics of each technology as mentioned above keeping in mind the entire Techno Commercial viability of the project
