OIL & GAS PROCESSING, TREATING
STORAGE & HANDLING SOLUTIONS
TransTech Fabrication is your source for high quality, custom engineered amine contactors for your gas treating operations. Our amine contactors are precision fabricated to your exact specifications to effectively remove acidic gases such as H2S, CO2 and SO2 from your sour gas stream, making it ‘sweet’ and suitable for pretreatment or pipeline specifications.
Amine contactors sweeten your gas stream through the process of absorption, using n-methyl diethanolamine (MDEA) or other alkylamines including Monoethanolamine (MEA), Diisopropanolamine (DIPA), or DIGLYCOLAMINE® (DGA®) Agent to chemically absorb contaminants out of the gas stream.
How it works
The contactor is a specialty high-pressure vertical vessel. Gas enters the bottom of the vessel, rising upward to meet with pre-cooled amine gas, which is fed from the top of the unit. Amine gas is kept at a higher temperature than that of the incoming gas stream to prevent hydrocarbon condensation and potential foaming problems. Alternatively, coalescers can be installed upstream of the contactor for removal of entrained liquids to eliminate the root cause of condensation.
As acidic gases are absorbed, light sweetened gas exits from the top of the contactor while acidic amine exits from the bottom, to be routed to your surge drum for hydrocarbon separation and then on to your regenerator to be recycled.
Precision Engineering & Fabrication
The allowable parts per million (ppm) concentration of amine left within sweetened gas is one of the most important parameters in the design of amine contactors. Our experienced team of pressure vessel experts will construct your amine contactor to the most exacting standards to meet all requirements and for the highest level of quality and safety, in accordance with your specifications.
We bring state-of-the-art manufacturing processes and technologies to every project we deliver and our modern, 160,000 square feet fabrication facility gives you access to one of the largest pressure vessel fabrication facilities in the United States.
We utilize the most modern CNC lathes and machining centers together with a full complement of manual tools to ensure the outstanding quality, performance and longevity of your finished contactor.
Our stringent quality control standards ensure every vessel we produce meets or exceeds all Division 1 requirements for design, materials, fabrication, welding and forging, inspection and testing.
