Gas Compression


Production from oil and gas wells can be increased using compression. Reduction of backpressure in well bores, increased pressures into sales lines, and recovery of hydrocarbon vapors from flaring enhances production.

Unimac LP offers solutions tailored to your specific application, we focus on selecting the correct compression design to maximize recovery and minimize initial cost.

Rotary Screw

Rotary Screw Compressors are extremely versatile, capable of discharge pressures up to 350 PSIG they are particularly efficient at discharge pressures from 50 to 200 PSIG. A wide range of gas flows from 20 to 15,000 MSCFD are available.

Unlike reciprocating designs the rotary screw features smooth operation resulting from no unbalanced forces and no pressure pulsation. No foundation is required and there are no piping vibrations from pressure pulsation. Relatively low maintenance and high reliability are inherent with rotary screws because they have few moving parts, there are no valves, rings or packing to wear out or cause loss of efficiency.

Sliding Vane

Ro-FloCutAwaySliding Vane Compressors are a cost-effective solution for vapor recovery and very efficient (MCFD per input HP) when the discharge pressure is below 60 PSIG (up to 150 PSIG available). A wide range of gas flows from 3 to 3,500 MSCFD are available.

Vane compressors can handle the toughest corrosive, sour, wet gas applications. The simple, rugged design has built a reputation for reliable service in extreme environments for decades and can be repaired in the field. Constant efficiency is maintained as the self adjusting vanes stay in contact with the cylinder.

Rotary lobe blowers are efficient (MCFD per inut HP) and ideally suited for unconventional gas like coal bed methane and VRU applications where the discharge pressure is below 15 PSIG. A wide range of gas flows from 50 to 6,000 MSCFDto are available.

The lobe blower features a dry compression chamber, which means it does not require a separate coolant or sealing circuit like a flooded screw, liquid ring or vane design.
