EPBC liquids

The San Juan plant can process up to 500 MMcfd of gas, and extract 40,000 bbl of EPBC liquids. EPBC liquids include ethane (E), propane (P), butanes (B), and condensate (natural gasoline) products... 

To extract die EPBC liquids, die plant employs a cryogenic temperature process in combination with a refluxed demedianizer process in two trains. The two turboexpander trains are die heart of die process and bodi have operated at efficiencies higher dian originally expected at die design stage. 

The liquid collected at the bottom of the demethanizer tower is a mixture of ethane, propane, butane, and condensate (EPBC), which is taken off in a stream and pumped—as a liquid, at 1,000 psig—to a customer facility. Another part of the EPBC is introduced into a deethanizer tower. The stream of EPBC liquid entering the deethanizer tower is further separated into PBC liquid and pumped to the El Paso Natural Gas facility in Gallup, New Mexico. EP (ethane and propane)... 

Probably the largest natural gas proeessing straddle plant in North Ameriea is BP-Amoeo s Empress, Alberta faeility. Here, EPBC (ethane, propane, butanes, and eondensate) are extraeted as liquids from natural gas before the gas is delivered to the TransCanada and Foothills (Saskatehewan) pipelines (Figure 8-5). The term straddle plant refers to the faet that the plant straddles the natural gas pipeline and extraets liquid eomponents before passing the natural gas further along the pipeline.
