USING THE RIGHT EXPERTISE EARLY REDUCES PROJECT COSTS

Examples:

Supercritical CO₂ dehydration plant expansion project for enhanced oil recovery client, 2002 to 2003 timeframe:

Client desired to increase throughput of facility by ~75% over historical levels.  Larger engineering company advised that client had to build a new dehydration facility at a cost of “3X” to get the increased flow. 

Through careful examination of the system 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 “1X”.  The structured packing and other modifications were installed and successfully started up.

This client saved over $1 million.

HDS project for a refinery seeking to desulfurize a C5+ stream, no existing sulfur recovery system, 2002-2003 timeframe:

Client’s original engineering contractor proposed conventional HDS system with caustic treatment of recycle hydrogen stream.

Via in depth knowledge of other available sulfur recovery options and selective HDS options, Trimeric staff showed client an option that reduced H₂ recycle compressor horsepower by slightly more than 50%, and reduced operating costs as well.  Trimeric staff also made client aware of selective HDS approaches that appeared capable of reducing hydrogen consumption by 50-75%.

This project is ongoing.  Potential savings to the client are in the millions of dollars.

Process Simulation Software:

Trimeric uses WinSim DESIGN II software for most basic process simulation.  This is a time-tested steady state simulator with state-of-the-art capabilities.  Design II has hydrotreater modules built into the software.  Trimeric’s staff also has extensive experience with ASPEN PLUS and other software for modeling aqueous chemical and physical solubility equilibria.
