Vapor Recovery in Natural Gas

Methane gas recovery is by no means a new appliucations – yet, the challenge thank fluctuating gas prices and environmental concerns mean for plant operators are immense. A new compressor technology is thus becoming a new de-facto standard….

Recovering methane gas vapors from tank batteries is not a new application for most owners and operators of oil-and-gas production companies and crude-oil storage-tank facilities. However, the economics for justifying the installation of Vapor Recovery Units (VRUs) on tank-batteries vary with the size of the storage facilities, as well as the prices at which the gas is selling. Also to consider, in addition to the regulations already required by the Clean Air Act (CAA), is the fact that there are increasing environmental regulations being considered by governmental entities such as the U.S. Environmental Protection Agency (EPA), regulations that can call for a significant reduction in the uncontrolled release of methane gas to the atmosphere.
Therefore, companies that want to take a proactive  approach to reducing the amount of uncontrolled releases of Hazardous Air Pollutants (HAPs) into the environment are taking another look at using non-lubricated reciprocating gas compressors for vapor-recovery applications.
Tank vapor-recovery applications, a market once thought to be off limits to non-lube designs due to the higher cost of oil-free (non-lube) reciprocating machines, are now becoming an economically feasible and environmentally smart choice for many operators…
