When compared to the traditional method of flaring propane and other liquefied petroleum gases (LPG), these mobile LPG evacuation units (photo, p. 55) offer a more-cost-efficient and safe alternative for removing residual gas from tanks that needed to be moved, repaired or replaced. The units feature the manufacturer’s LB Series reciprocating gas compressors — model numbers LB161, LB361 or LB601, specifically. In addition to a trailer-mounted unit, a skid-mounted version is offered for easy transportation in a truck bed or via a small trailer to the destination. The portable liquid-transfer and vapor-recovery units are constructed with a variety of engine drive styles and options. The units are designed with the traditional "LU" mounting style, which includes the compressor, liquid trap, strainer, four-way valve and related piping. LB Series compressors are available with transfer rates from 35 to 700 U.S. gal/min (132 – 2,630 L/min) and designed to handle transfer and recovery of liquefied gasses like propane, butane, and anhydrous ammonia. All models feature ductile iron pressure parts for greater resistance to both thermal and mechanical shock. — Blackmer, Grand Rapids, Mich.
