Print this case study

The processed oil in Heglig Central Processing Facility (CPF) is being exported to Sudan Port via 28" crude oil export pipeline supported by 6 pump stations. Greater Nile Petroleum Operating Company (GNPOC) export oil specifications is BS&W <=0.5%.

Lately, the export oil BS&W has been observed to exceed the specification more frequently. An efficient method shall be sought to enhance the CPF processing efficiency keeping in consideration upgrading of CPF facilities including addition of more tanks. As per process design, un-separated emulsion in the Electro-Static Treaters (ESTs) should flow to the Off-Spec Tank, and then be recycled back to the ESTs for reprocessing. However, the process gets upsets whenever off-spec tank contents are recycled to the ESTs. To overcome this, the off-spec tank contents have been spiked directly to Crude Oil Storage Tank (COST) after water draining.

ECG scope includes design of fixed roof Off-Spec Storage Oil Tank 10,000 BBL capacity with all needed attachments and accessories, sizing selection of an offspec oil spiking pumps, design of interconnecting piping from & to the off-spec oil tank / off-spec spiking pump including piping layout, stress analysis, pipe supports and isometrics, instrumentation & control of the system, design of fire protection system for the Off-Spec Storage Oil Tank and electrical designs for power, lighting, earthing, lightning & cathodic protection.
