In 2009, the company independently invested more than 2 million yuan to build this set of test equipment in the company's park. The whole set consists of adsorption tower, program control valve, compressor, PLC control system, pretreatment system, instrumentation, etc., forming a set of independent Complete test device that can be independently commissioned. The test device uses a separate gas distribution method to simulate the separation of any gas composition in an industrialized plant, which plays a key role in the research and development of our company. Therefore, the test equipment, our company successfully developed pressure swing adsorption sulfur concentration, pressure swing adsorption from more complex refinery tail gas purification of CO, C3 ~ 5, CH4 and other active ingredients, pressure swing adsorption high purity oxygen and other advanced technology .

At the same time, our company's adsorbent needs to test the adsorption performance on this device every time it is technically improved. It is also an important means to ensure the performance of the company's adsorbent.
