Abstract: A method for reducing emissions from a vessel includes isolating the vessel from a downstream fluid flow line, purging a fluid from the vessel by injecting purging media into the vessel to push the fluid through a check valve of a vent tubing and into the downstream fluid flow line, and draining the purging media from the vessel. A first end of the vent tubing is coupled to the housing of the vessel, and a second end of the vent tubing is coupled to the downstream fluid flow line. Further, the vent tubing includes a check valve disposed between the first end and the second end, and the check valve is configured to allow fluid to flow from the housing to the downstream fluid flow line.

Abstract: Methods and compositions for skid-mounted separator assemblies are provided. In some embodiments, the compositions comprise at least one mobile skid, wherein the at least one mobile skid has a first frame and a second frame, and wherein the first frame is hingedly coupled to the second frame. In some embodiments, at least one separator is mounted upon the at least one mobile skid.

Abstract: Methods and compositions for processing a gas produced from an oil and gas well are provided. In some embodiments, the compositions include a wellbore penetrating at least a portion of a subterranean formation. The compositions further include one or more fluid flow paths in fluid communication with the wellbore, the one or more fluid flow paths having at least a first segment and a second segment. The compositions further include at least one heat exchanger. The compositions further include an expander coupled to a generator in fluid communication with the gas in the second segment. The gas in the first segment flows through the at least one heat exchanger wherein it is cooled to the point of forming CNG, and the gas in the second segment flows through the expander to generate electricity.
