1 OIL HANDLING SYSTEMS Oil is treated and stored at HI 376 A before it is pumped through a LACT unit to the Departing Oil Pipeline. The Oil Handling System is composed of the Primary Oil Handling System and the Secondary Oil Handling system. The Primary Oil Handling System consists of all equipment associated with oil treatment and storage; Chemical Electric Treater (NBK-3300), Oil Storage Tank (ABJ-1250), Over Flow Oil Tank (ABJ-1260) and the manually operated bottoms pump on each tank. The Secondary Oil Handling System includes the components involved in sending the oil down the pipeline; the LACT Pumps (PBA-2030/2040), LACT Skid, Pipeline Pumps (PAX-2220/2210/2140/2150) and the Departing Oil Pipeline (KAH-7030). Primary Oil Handling System: Oil discharged from the Oil Separators is dumped to the Chemical Electric Treater. Water separated from the oil is dumped to the Water Skimmer (MBM-1060). Oil discharged from the Treater flows to the Oil Storage Tank. Once a sufficient level has accumulated in the Storage Tank, the Secondary Oil Handling System is activated to ship the oil down the Departing Oil Pipeline. The Overflow Oil Tank is common with the Oil Storage Tank and handles excess input. A manually operated pump is installed at each tank to circulate the tank bottom back to the Chemical Electric Treater. Secondary Oil Treating System: When the Secondary Oil Handling System receives a run signal, the LACT Pumps (PBA-2030/2040) send the oil through the LACT Skid to the suction of the Pipeline pumps (PAX-2220/2140/2210/2150). The Pipeline Pumps discharge to the Departing Oil Pipeline (KAH-7030). The pipeline is protected from overpressure by a PSH and PSV on each of the Pipeline Pumps. 6 Departing Oil Pipeline (KAH-7030) Segment No carries oil away from HI 376 A to Amoco. The line is 6 and has a maximum allowable operating pressure (MAOP) of 2160 psig. Rev: 0 Date: 11/11/11 Page 1 of 8 HI A-376 A
