Process principle:
After the raw material gas enters the adsorption tower of the PSA device, the adsorption capacity of the adsorbent in the tower for ethane (C2) and hydrocarbon components above C2 varies with the change of pressure. Under pressure, C2 and above hydrocarbon impurities in the raw material are adsorbed, and the unadsorbed gas (purification gas) is exported from the adsorption tower as a product. During decompression, the adsorbed impurities are desorbed and desorbed from the adsorbent, while the adsorbent is regenerated. At least four adsorption bed cycles are used to achieve continuous output of purified gas.Raw gas:
Natural gasControl mode and characteristics:
Control mode: Use
controller and instrument to control PSA device. The controller can choose DCS, FCS, PLC control system according to PSA device scale and control requirements.Control features:
not only the conventional control of the system is realized, but also the expert control and adaptive optimization control of any combination and arbitrary switching of multiple towers are realized, which not only improves the flexibility of the operation of the device, but also ensures the long-term, stable and safe operation of the PSA device.Service mode:
Provide patent and proprietary technology, provide a full set of device designProvide general contract for equipmentProvide technical service and personnel training during installation and commissioningThe device is guaranteed for one year after acceptanceLong-term supply of spare partsEmail：tlqt@mljmc.cn
