The Use of Activated Carbon in Amine Filtration Systems

During the processing of natural gas, it becomes contaminated with various substances, including natural oil, H2S, CO2, particles, and other acidic gases. Amine-based sulfur removal technology is commonly employed to eliminate these contaminants. This technology typically utilizes solutions such as 40% MDEA and 20% DEA for the removal of H2S and CO2 in TGTU and AGRU units.

The alkylol amine technique is extensively used, particularly for purifying natural gas on a large scale. However, the use of MDEA or other solvents can lead to issues such as solution degradation, contamination, and corrosion. These problems can impact the proper functioning of the unit, potentially resulting in substandard product gas, solvent loss, and damage to the facility. Foaming of the solution is a primary concern among these issues.

In liquid sulfur removal systems using amine, the use of activated carbon plays a crucial role in addressing problems such as frequent filter washing, device corrosion, foaming, and amine liquid loss. Activated carbon effectively removes the amine degradation compound (foam inhibitor), ensuring a more stable performance in the system.

The role of activated carbon in amine filtration systems is critical for clean and efficient processing in the natural gas industry. High-performance amine filtration systems form the foundation of sustainable and efficient natural gas processing facilities.
