High Performance Adsorption System

Functioning High Performance Adsorption System

16 April 2021

Pressure Swing Adsorption (PSA) is the process that causes compressed air to be converted to a mixture of pure nitrogen. The purity of the nitrogen can be adjusted based on the desired application. The compressed air required for this can be supplied by a dedicated compressor or by an in-house compressor.



The PSA process is as follows:

The cylinders are filled with activated carbon. PSA cylinder 1 (left) is pressurized with compressed air. The oxygen molecules are retained by the activated carbon and the nitrogen molecules are allowed to pass through. The system consists of two cylinders working together. During the process, 1 cylinder is producing nitrogen while the other is regenerating.

HPSA system

Based on the PSA technology, Presscon has developed its own system that deals with the disadvantages of traditional PSA systems; the High Performance Adsorption system. The HPSA technology distinguishes itself by an optimized air flow in the system and a unique pressure system for the activated carbon. These improvements create a system that is environmentally friendly with a significantly longer service life and lower energy consumption. Our patented compression tubes require less than 2 m3 of compressed air to produce 1 m3 of 95% pure nitrogen.

In addition to low compressed air consumption, when using a Presscon nitrogen generator, a compressor with a lower capacity can be used to achieve the desired compressed air volume, or the additional capacity of the compressor can be used in another business process. Nitrogen purity can be set to 99.9997% with our HPSA systems.

Compared to the traditional PSA technology, the HPSA offers a substantial energy saving of 30%, and when compared to a membrane system the energy savings can be as high as 50%!
