Sour natural gas compositions can vary over a wide concentration of H2S and CO2 and a wide concentration of hydrocarbon components. If the H2S content exceeds the sales gas specification limit, the excess H2S must be separated from the sour gas. The removal of H2S from sour gas is called "sweetening."

Petrofam has been designing and manufacturer amine sweetening plants using a variety of amines (MEA, DEA, DGA, MDEA and MDEA based proprietary amines). Petrofam designs custom units to meet a variety of operating conditions and as an example can incorporate the following depending on the Customer's needs:

• High efficiency inlet lube oil separators to remove lube oil carryover from upstream compression to minimize foaming.
• Amine re boilers using either a directly fired fire tube, heat medium or an electric immersion heater.
• Specialty materials on portions of the facility if required.
• Corrosion inhibitors, anti-foam injection facilities.
• Water and amine makeup facilities.
• Acid gas disposal and sulphur recovery. Downstream gas scrubbing, dehydration and/or processing for hydrocarbon dew point control and/or liquid recovery

A system designed and manufactured by Petrofam is engineered with characteristics specifically suited for each unique application requirements. Petrofam employs seasoned engineers and fabricators, and utilizes advanced fabrication processes to ensure a superior product. The system can be provided as a complete package including piping, instrumentation/ electrical and valving requirements considering Client Specifications
