Amine Units

The hydrocarbon treating process includes the removal of contaminants from natural gas. Gas treating or "sweetening" are both terms used to describe the various processes for the removal of certain contaminants, primarily hydrogen sulfide (H2S) and carbon dioxide (CO2), from natural gas or hydrocarbon liquids. CO2 and H2S are also termed “acid gases” due to the formation of an acidic solution when absorbed in water. In addition to CO2 and H2S, the sulfur acids, carbonyl sulfide (CS2), carbon disulfide (COS), and the mercaptan family (RSH), when present in sufficient quantities, are also candidates for removal with specific amines. QBJ utilizes primary (MEA or DGA), secondary (DEA), and tertiary (MDEA) alkanolamines. 

  Why Remove CO2 and H2S From Natural Gas?     

  • Toxicity
  • Corrosive to Equipment
  • Prevents Hydrate Formation
QB Johnson Manufacturing, Inc. has over 40 years of experience designing and manufacturing amine units. QBJ can engineer, design, and manufacture treaters for any application and custom designs all units to fit customers' needs. QBJ has experience in designing new amine treaters from 3 GPM up to and including 600 GPM. All units are modular and skid mounted in order to reduce field installation time and costs to our customers.
