Basic Info
  • Model NO.: 1, 600Nm3/h NG Purification Unit in Thailand
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) are adsorbed on pressurization, while the unadsorbed gas(purified gas) is obtained from the outlet as product. On depressurization, the adsorbed impurity components are desorbed from the adsorbent and the adsorbent can be regenerated. At least four adsorbers are needed for the recycling operation so as realize continuous output of the purified gas.

· Feed gas
*Natural gas

· Technical data
* Feed gas:
Pressure: 0.3~0.8 MPa(g)
Temperature: Normal temperature
* Product gas: Purified gas
C2: ≤ 100ppm
C3: ≤ 30ppm
CH4 recovery: 70~90%
System pressure dropΔ P: 0.10MPa
Temperature: Normal temperature
Note: CH4 recovery depends on the feed gas composition, pressure and CH4 purity.
* By-product gas: Desorbed gas
Pressure: ≤ 0.02 MPa(g)
Temperature: ≤ 40 º C

· 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.

· Mode of Service
* Provide the patent & proprietary technology and design.
* Provide EPC
* Provide technical service and staff training during plant installation & commissioning.
* The plant has 1-Year warranty period since inspection and acceptance.
* Provide spare pare and accessories over a long period.
