High Purity 12000Nm3 Hydrogen Purification Unit PSA Technology

Shanghai NEW-UNITY ENERGY 12000Nm3 SMR Hydrogen Plant,PSA Hydrogen Plant

Technology Application

Techairs is professional engaged in gas preparation, separation and purification technology research and development and engineering transformation. It is widely used in petrochemical industry, coal chemical industry, fine chemical industry, gas industry, ethanol industry, photovoltaic semiconductor industry and PTA industry.Unique THiPSATM technology and FrTPSA technology can achieve high purity, high yield, low material consumption and low energy consumption; Separation of multicomponent gas and low separation coefficient gas.

Absorption

After feed gas enters absorption tower from the bottom, impure components in feed gas will be absorbed on a selective basis by multiple kinds of adsorbents. Hydrogen not absorbed will be used as product gas and conveyed to user. With this step, conforming product gas can be obtained.

Desorption

① Equalization depressurization

After finishing absorption, high-pressure hydrogen in tower will conveyed to other low-pressure absorption tower having realized regeneration along absorption direction. This process not only is a depressurization process but also absorbs hydrogen in adsorbent bed space. It includes three times of continuous equalization depressurization, so that hydrogen can be fully recovered.
