PSA With Imported PLC Control Automatic Operation To Realize Real Unmanned Operation

Working Principle Description:

PSA (pressure swing adsorption) is a process of purifying gas mixture. The process is based on the physical adsorption of gas molecules on the internal surface of porous solid substance (adsorbent) and works in a reversible physical adsorption process between two pressure states. It is based on the fact that the impurity components in the mixed gas have greater adsorption capacity under high pressure and have higher adsorption capacity under low pressure.

The ideal component H2 has smaller adsorption capacity no matter in high pressure or low pressure. Under high pressure, the impurity partial pressure is increased to adsorb on the adsorbent as much as possible, so as to achieve high product purity. Desorption or regeneration of adsorbent is carried out under low pressure to minimize the residual amount of impurities on the adsorbent, so as to adsorb impurities again in the next cycle.

Product Advantages:

· Imported PLC has the feature of high-quality, it can work for a long time and control operation automatically;

· Perfect process design has the advantages of low operation cost, low energy consumption and high efficiency;
