Basic Info
  • Model NO.: 30, 000 Nm3/h PSA-C2H4 Unit at Sinopec BJ Yanshan
Product Description
Process principle
Due to different adsorption capacities of adsorbents for various gas components in feed gas under various pressures. The hydrocarbon components (C2 and above) such as ethylene and ethane are adsorbed on pressurization, while the weak adsorptive components like H2, CH4, O2, N2, CO are discharged from the outlet. When depressurization or evacuating, the adsorbed hydrocarbons (C2 and above) are desorbed from the adsorbent as semi-product gas and the adsorbent can be regeneration. After pressurization, the semi-product gas enters purification system so as to remove
Impurities like H2S, organic sulfur, CO2, arsenic, water, etc.

Feed gas
*FCC dry gas, coking dry gas
*Other gas mixtures containing ethylene.

Technical data
* Feed gas:
Pressure: Pressure of dry gas
Temperature: Normal temperature
* Product gas: Ethylene purified gas
Arsenic content: <5ppb
Sulfur and organic sulfur content: <0.1ppm.
CO2 content: < 1ppm
H2O content: <1ppm
O2 content: <1ppm
It can be produced according to different use and requirement of the customers.

Control mode and characteristic
Control mode: PSA units are controlled by controllers and instruments. The DCS, FCS, PLC control systems can be chosen according to the scale of PSA units and the requirement of control.
Control characteristic: The implementation of not only the PSA ordinary control system, but also the specialist control system for optional combination and switchover of multiple-adsorbers, and the self-adapt optimum, which improves the operation flexibility, and ensures the long-term, steady and safe operation of the unit.
