Recent GPA data improves BTEX predictions for amine sweetening facilities
Language: Inglés Subject(s): Online resources: Summary: Amine solutions absorb some amount of hydrocarbons and BTEX. These dissolved hydrocarbons that are obtained by contacting with the feed gas are ultimately released in the overhead of the regenerator. This overhead either vents to the atmosphere or feeds a sulfur recovery unit. Hydrocarbon content for regenerator vents discharging to the atmosphere must comply with recent stringent regulations. For acid gas feeds to a Claus unit, excessive hydrocarbons may result in catalyst fouling, sub-quality sulfur product, or more sophisticated burner design. To better understand and quantify hydrocarbon and BTEX solubility in aqueous amines, the Gas Processors Association commissioned research Project 971. Preliminary results from this project have been used to improve models for hydrocarbon and BTEX solubility predictions. Model predictions are compared with operating facilities and guidelines for minimizing hydrocarbon absorption in amine facilities are presented.| Current library | Status | Barcode | |
