  • Bicine can be controlled

    Bicine is a very corrosive degradation product produced in certain DEA and MDEA systems. Amine system operators must take steps to minimize O2 and SO2 incursion into the amine system and will need to monitor Heat Stable Salts and Amino Acids (Bicine) concentrations in the amine.

  • Comparing physical solvents for acid gas removal

    Physical solvents such as DEPG, NMP, Methanol, and Propylene Carbonate are often used to treat sour gas. These physical solvents differ from chemical solvents such as ethanolamines and hot potassium carbonate in a number of ways. The regeneration of chemical solvents is achieved by the application of heat whereas physical solvents can often be stripped of impurities by simply reducing the pressure. Physical solvents tend to be favored over chemical solvents when the concentration ...

  • COSWEET™ deep COS removal from natural gas

    By combining amine absorption with catalytic COS hydrolysis, COSWEET™ allows gas sweetening, either total (removal of both H₂S + CO₂) or selective (removal of H₂S mainly), with complete COS removal. The three steps of COSWEET™ process consists in: * Removing the bulk of the H₂S and CO₂ present in the feed gas by absorption in the bottom section of a solvent absorber. * Withdrawing the partially sweetened gas from bottom section of the absorber, water ...

  • Cyanide corrosion causes costly upsets

    Refinery cyanides cause considerable corrosion, hydrogen blistering and waste water treatment problems. The majority of refinery cyanides are formed in the reactor of fluid catalytic cracking (FCC) units. All of the gas from the reactor, including the cyanide, is carried overhead into the distillation column, where water is injected into the overhead stream to control corrosion problems. The resulting sour water is separated from the hydrocarbon products at various stages in ...

  • Removal of foaming

    In a recent case history, an East Coast Refinery was experiencing frequent upsets in their amine system due to foaming. MPR Services was contacted and brought in their SigmaPure™ System. SigmaPure removed the foaming agents and the unit returned to optimal operations. Operations management and Engineering were very pleased and the refinery gas treating system significantly increased performance completely eliminating upsets and reducing amine purchases.

  • Running dirty amine to save costs

    Some plants have saved money in the short term by running dirty amine/glycol systems. The result of this obfuscation strategy often is problematic operations. Problems resulting from corrosion, foaming and loss of acid gas absorption arise from processing with contaminated amine/glycol. A single severe process upset resulting in a large solvent loss may put you over budget for the year. We know how important controlling amine/glycol losses and costs can be. MPR Services, Inc. ...

  • Selecting the best solvent for gas treating

    Selecting the best amine/solvent for gas treating is not a trivial task. There are a number of amines available to remove contaminants such as CO2, H2 S and organic sulfur compounds from sour gas streams. The most commonly used amines are monoethanolamine (MEA), diethanolamine (DEA), and methyldiethanolamine (MDEA). Other amines include diglycolamine® (DGA), diisopropanolamine (DIPA), and triethanolamine (TEA). Mixtures of amines can also be used to customize or optimize the ...
