What is a VRU? A VRU, or vapor recovery unit, is a compression system used to collect and compress low volume gas streams for injection into the suction of a larger compressor, a meter run, a local site fuel gas system or directly into a gas gathering line. Mechanical VRUs consist of a driver motor or […]
Process Description To meet pipeline specifications, operators are often required to dehydrate their produced natural gas that is saturated with water vapor. Water vapor in natural gas pipelines can result in the formation of hydrates that can obstruct or plug the pipe. Also, water vapor in a pipeline can cause corrosion due to the presence of carbon […]
Federal and State regulatory rules require oil and gas (O&G) operators to reduce natural gas venting and leaks from their operations. NSPS OOOO has standards for VOC emissions from storage tanks, compressor seals, pneumatic controllers and fugitive leaks (primarily natural gas processing). NSPS OOOOa has standards for VOC emissions from storage tanks, compressor seals, pneumatic controllers, pneumatic […]
Operators use enforceable limits in air permits to avoid triggering NSPS OOOOa applicability for crude oil, condensate and produced water storage tanks. To obtain an enforceable limit, the limits must be included in a legally and practically enforceable air permit or other authorization. Air permits granted by a federal, state, local or tribal authority typically […]
For oilfield storage tanks, NSPS OOOO and OOOOa have similar requirements regarding applicability, emission limitations, recordkeeping and reporting requirements. Some exceptions for storage tanks are different applicability dates for the two rules and NSPS OOOOa has additional requirements for closed vent systems (piping) used to control NSPS OOOOa affected facility storage tanks. These rules affect […]
There is a continuing focus by regulators on the tightening of the regulation of vent gas (VOCs, methane) from oil and gas operations. These regulations place a large liability on industry to know the regulations and comply with all of the emission controls, standards, testing, record keeping and reporting requirements. As regulations are incorporated into […]
ƒAll over the media there is news about climate change and greenhouse gases (GHGs). Many in the oil and gas industry do not work directly with GHG issues but most realize that this issue will greatly affect their companies. This is a brief summary of GHGs and the oil and gas industry. What are […]
Air permits for oil and gas (O&G) production facilities include Federal EPA and State requirements for storage tanks for crude oil, condensate and produced water. The main EPA rules applying to O&G storage tanks are the New Source Performance Standards (NSPS) OOOO and OOOOa. Individual state environmental regulatory agencies may have their own storage tank regulations that might […]
Flares as Emissions Control Devices Flares are combustion devices used to burn off associated, unwanted or excess combustible gases during many industrial processes, such as oil and gas extraction, refineries, chemical plants, coal mines, bioreactors, and landfills. Flares are used both as safety (pressure relief) devices and as emissions control devices. Based on tests […]
