S&S solution to growing rail terminal expansions

New propane and butane rail terminal expansions are occurring across the U.S. and S&S Technical has provided custom LPG offloading solutions for a number of major midstream companies across the county.

The company recently completed and shipped a custom packaged system bound for an Ohio-based rail terminal. This most recent package included two Blackmer LB942B reciprocating compressors on a common skid with a 4” vapour header and 4-way valve.

The 4-way valve controls the direction of vapour flow through the two compressors, allowing the operators to select between liquid transfer offload and vapour recovery modes to capture the maximum amount of product from the top loading, pressurised railcars.

Due to some concerns with excessive liquids resulting from older piping design at the site, S&S furnished oversized ASME suction scrubbers that included an automated dump system to protect the compressors from the potential for liquid slugging – a common occurrence in LPG compression applications which can result in catastrophic equipment failures and at a minimum, long term reliability concerns.

As continued natural gas exploration and drilling continues, the need to move LPG products will grow as well.
