TURNING crude oil into usable petroleum products is by its nature a gritty business, including the production of flare gas – which is a mixture of waste hydrocarbon gases – during the refining process.

In the past, those gases were burned off, emitting pollutants into the environment. To capture and recycle flare gas can be both a significant environmental improvement and a source of money when the gases are sold or reused in the process.
Because flare gas is highly contaminated, capturing these by-products calls for equipment that can handle dirty, corrosive and explosive gases without breaking down or requiring frequent maintenance — critical requirements for refineries, which run 24/7. That makes flare gas recovery a perfect job for Gardner Denver Nash liquid ring compressors which, because they have only one moving part, can handle the most demanding applications without clogging or breaking down. Nash invented liquid ring vacuum pumps and compressors and offers the broadest range of pressures and flow rates. These products are supported with design and engineering capabilities that enable Gardner to create custom, Engineered-to Order systems that meet our customers’ specific needs. Other refinery jobs for Gardner liquid ring pumps include vacuum distillation, removal of wax from lubricating oil stock and recovery and reuse of petroleum vapour from storage tanks. The bottom line is that almost every refinery includes Gardner equipment. Other Gardner products are found in refineries as well, including blowers used in the removal of sulphur from “sour gases” — gases that contain hydrogen sulfide — and reciprocating compressors for process gas applications.
