  • Auto-switch boring / cutting tool

    The innovative DeltaValve auto-switch coke cutting tool provides a high level of safety and reliability during de-coking operations by allowing the tool to remain in the drum during switching between boring/cutting modes. The auto-switch tool, in combination with the DeltaValve drill stem guide enclosure and the top unheading valve, provide maximum coker safety by allowing personnel to be removed from the cutting deck. Flow channels in the auto-switch tool are optimized to ...

  • 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 ...

  • Optimizing CO2 capture, dehydration and compression facilities

    The removal of CO2 by liquid absorbents is widely implemented in the field of gas processing, chemical production, and coal gasification. Many power plants are looking at post-combustion CO2 recovery to meet environmental regulations and to produce CO2 for enhanced oil recovery applications. The figure below illustrates actual data of fuel consumption in 2005 and an estimate of energy demand for various fuels from 2010 to 2030. The world energy demand will likely increase at rates ...

  • 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 ...

  • Sulfur recovery

    With increasing environmental concerns, sulfur recovery has become one of the leading issues in emissions reduction. Bryan Research & Engineering’s process simulator, ProMax, contains a complete reactor suite for modeling kinetic (plug flow and stirred tank), equilibrium, conversion, and Gibbs minimization schemes. A variety of sulfur recovery and tail gas cleanup processes may be modeled using this suite of options. Some of the most commonly modeled processes include: • ...
