Fuels stored in tanks, including gas and oil, emit vapors that contain methane, propane, butane and other substances. The fumes from these materials are noxious and potentially flammable. In addition to being an environmental and safety hazard, these escaping vapors can also cost the operator money in terms of lost fuel. The purpose of a vapor recovery system is to capture these fumes and return them to the storage tank before they can escape into the atmosphere.
What to Look for in a Vapor Recovery System
There are a number of important factors to consider when selecting the most appropriate vapor recovery system for your operation:
- Volume and flow rate
- Chemical composition of the gas or oil
- Level of liquid content in the fuel
- Pressure and temperature of the gas or oil to be recovered
- Discharge pressure and temperature
- Availability of a power source to drive the vapor recovery pump, compressor and other system components
- Presence of carbon dioxide or hydrogen sulfide in the gas or oil
- Potential for contamination from atmospheric oxygen
Quincy’s Line of Vapor Recovery Compressors
A compressor is an important element of any vapor recovery system. Quincy Compressor offers a wide assortment of screw, reciprocating, and rotary vane compressors for just about any vapor recovery process or application.
Quincy rotary screw gas compressors, for example, are designed to deliver maximum gas flow with minimum horsepower. These compressors feature an innovative direct-drive rotor profile that provides consistent and reliable performance. It is also designed, engineered and manufactured to provide the durability you would expect from any Quincy Compressor product. The exclusive triplex bearing configuration offers a calculated lifespan of up to 130,000 hours. The positive displacement gear-type fluid pump keeps the rotors and bearings fully lubricated, which helps to prolong compressor life by keeping major repair and maintenance issues to a minimum.
A number of optional features and accessories are also available for Quincy vapor recovery compressors. These include gas engines or electric motor drives, shaft-driven positive displacement pumps, oil and gas separator tanks and variable displacement lift valves.
The QRNG is a reciprocating gas compressor series featuring heavy-duty cast iron construction for superior strength and durability. These compressors are also equipped with an advanced pressure lubrication system, low-lift valves and rebuildable connecting rods. You can choose between single-stage 2-34 horsepower and 13-33 two-stage units that provide the low-cost gas compression you need.
Other key QRNG features include individual valve pockets that simplify the preventive maintenance process, high-efficiency cast-iron cylinders, intercooler with large circular fins for maximum heat dissipation and lapped cast-iron valve seals that prevent the need for a discharge line check valve.
