Natural Gas Services for a Northeast US City – Utility Curtailment

CLEANCOR contracted with a major utility in the U.S. Northeast to provide an uninterrupted supply of natural gas via its mobile LNG regasification solution for a one-day duration of a scheduled maintenance project. It became clear that the system demand for gas was going to be twice as high as expected, partly due to the anticipated cold weather conditions. CLEANCOR’s revised solution included additional pipeline tie-in points, larger bore hoses, high-flow regulators and bypass valves to cope with the additional increase in demand.

The project, planned two (2) months in advance, was anticipated to last a total of one (1) day and required LNG supply of a minimum of 208 thousand cubic feet per hour (MCFH), 24 hours a day. CLEANCOR deployed four (4) high-pressure storage units with a total capacity of 44,000 gallons of LNG, with two (2) additional LNG transfer trailers used as refueling units to meet the daily volume demand. CLEANCOR upgraded the equipment package to meet the increased demand and successfully provided a consistent flow rate at the requested pressure of 75 pounds per square inch (PSI) at the inlet for the duration of the project. CLEANCOR’s technical staff members were on site 24 hours a day monitoring flow rates and receiving refueling deliveries until service to the area was restored.
