Figure 4-58. Metering station
One important function that can be performed at the metering station is the activation of the shut-off
valve in the case of operational issues or safety concerns. These metering stations are linked into a
SCADA (supervisory control and data acquisition) system which consists of a series of instrumentation
that transmits data into a computer system to monitor and control the facility. The station can be
monitored by on-site personnel or remotely from a centralized control room at an off-site location.
4.6.6 Produced Water Tanks
One of the bi-products / waste generated within a processing facility is produced water. Within the
midstream sector this is a broad term that includes actual formation water that is absorbed into the gas
molecules, condensates and other residuals that are processed out of the gas stream. This produced
water is routed over to tanks for storage and eventual disposal. These produced water tanks are also
commonly referred to as “slop water” tanks because of the variety of liquid waste streams that are
often deposited into them. Depending upon the waste / water volumes anticipated, there are typically
several (1 – 4) tanks linked together and referred to as a tank battery. The tanks are made of steel or
fiberglass and can range in size but a typical volume would be 400 to 500 gallons (each tank). The tank
battery is built with a secondary containment system to control spillage and a series of valves to
facilitate their draw-down for disposal.
