Hydrogen Sulphide, Carbon Dioxide and Mercaptans can be removed from Natural Gas by several processes, including:
- Amine Plants (shown here) utilizing MEA, DEA, DGA, MDEA and MDEA based proprietary amines (for all three - effectiveness varies for Mercaptans)
- Molecular Sieves (H2S and Mercaptans)
- Batch processes such as Iron Sponge, Sulfa Check and Chem Sweet (H2S)
- Membranes (H2S) - proprietary process
- Physical solvents such as Sulfinol and Ifpexol
The selection of the appropriate process for your application depends on the sales gas specifications, the cost of utilities and chemicals, and the ambient conditions.
Each process has its advantages and disadvantages. Let me help you choose.
- Note: Many of these processes can also be utilized to sweeten hydrocarbon liquid streams.
