Examples of Experience Relevant to CO2 Processing and/or
Sequestration:
  • Debottlenecking study at a 150 MMscfd supercritical CO2
    dehydration facility - client desired to increase throughput of
    facility by ~75% over historical levels.  Through careful modeling
    and consultation with an outside expert with specific supercritical
    CO2 experience, Trimeric staff proved that the expansion could
    be accomplished by replacing existing trays with structured
    packing, and making other minor modifications to certain pieces
    of the existing plant.  Net cost of the plant expansion using this
    route was 1/3 that of client’s other option, building a new facility.  
    The structured packing and other modifications were installed
    and successfully started up.  This client saved over $1 million.
  • Engineering feasibility study – Conceptual design and cost
    estimates for two CO2 processing options: 1) compress, cool,
    and dehydrate CO2 with glycerol under supercritical conditions,
    and 2) dehydrate CO2 with TEG under subcritical conditions,
    chill, condense, and then pump the liquid CO2 into the sales
    pipeline.
  • CO2 delivery pipeline capacity evaluation - Modeled 80-mile CO2
    delivery pipeline to predict maximum pipeline capacity under
    various feed conditions with multiple customer draw-off points
    along the line.
  • CO2 gathering system network evaluation – Modeled CO2
    gathering system network to identify bottlenecks and options for
    increasing capacity.  Problem required simulating supercritical
    CO2/water two-phase flow using specialized pipeline simulation
    software.
  • Equipment selection for CO2 liquefaction unit.  Evaluated several
    different conventional and compact heat exchanger designs and
    prepared equipment specifications for 18 MMscfd CO2
    condenser.
