VariPSA PSA VSA Analyzer

VSA PSA Adsorption Analysis for Labs

Stock Status: In Stock


Sorption effects are industrial used in pressure swing adsorption plants (PSA), e.g. for bio methane purification. Thereby adsorber vessels, filled with zeolites or carbon molecular sieves, are flown through by gas mixtures. Carbon dioxide is absorbed by the sorbent materials, leading to a pure methane flow, which can be used for power generation. Another industrial application is the nitrogen generation from ambient air. A continuous supply of product gas is carried out by batch operation of several adsorbers.

For an investigation of these processes under realistic conditions, RuboLab offers specialized laboratory scale PSA systems. The fully automated instrument can be used to measure breakthrough curves within adsorber columns. In addition, complex PSA and VSA processes can be investigated using two or more adsorbers (max. 10). Therefore, the standard system is equipped with two stainless steel adsorber vessels, which can be filled with sorbent materials. By means of thermal mass flow controller and a pressure regulation device, we can realize system pressures of up to 69 bar.

Fluid handling is done by using pneumatically high pressure valves and metal sealed fittings to ensure lowest leakage rate and best vacuum conditions. The adsorption front can be detected using 5 different temperature sensors. Adsorber breakthrough is measured using gas analyzation sensors like NDIR, TCD, GC or MS.


Costumer Specific Upgradability

The standard RuboSORP BTC/PSA (VariPSA) version contains two adsorber columns. In addition, the system can be expanded with further adsorber vessels (max. number of 10 columns). The volume of each adsorber bed can be adjusted using inner containments.

Full Automation

The Rublab Vari PSA Software allows a fully automated measurement performance of complex PSA or VSA studies. Online measurement data is shown on the integrated touch display. All data are saved in ASCII format and can be copied using a USB port at instrument front panel.

High Resolution Sensor Technology

The RuboSORP BTC/PSAsystem contains high resolution pressure and temperature sensors to ensure best measurement accuracy. The used premium pressure sensors are working within a measurement uncertainty of 0.04 % FS.
