Removal and Disposal of BTEX Components from Amine Plant Acid Gas Streams
The amine process will absorb heavy hydrocarbons and aromatics from gas streams in addition to the acid components. Whether the acid gas is to be vented or fed to a sulfur plant, it is highly desirable to remove these compounds from the acid gas. A new, economical process has been developed to greatly reduce the aromatics and heavy hydrocarbons in the amine plant acid gas stream. In the test facility, the new BTEX-T. rex process decreased the level of aromatics in the acid gas stream by more than three quarters. The process utilizes the plant fuel gas as a stripping agent and the aromatics and heavy hydrocarbons which are removed are incinerated in the amine plant reboiler heater. Plant data collected before and after implementing the BTEX-T. rex process compare favorably with the results estimated using a recent version of TSWEET regarding BTEX concentration results.
