Sealless pumps for the petrochemical industries
Following the API standard relating to the use of sealless pumps in the petrochemical, oil and gas industries, Hermetic Pumps launches the CNP API 685 series as part of their canned motor pump range
Magnetically driven self-cleaning filter launched
Available from Axflow Limited, the MCF is a unique filter that employs magnetically coupled drive technology to move the self-cleaning disc, eliminating the need for shaft or external drive seals
The contract for the motive water and reject return pumps was placed by Opus Maxim and covered the supply and factory acceptance testing (FAT) of four API Waukesha positive displacement rotary pumps for the produced water handling package.
The Compact Flotation Units (CFUs) provide effective removal of small oil droplets and other compounds from produced water, which proves to be difficult when using traditional gravity based methods.
The units selected were two 320U2 Reject Return Pumps capable of delivering 46.4m/hr and two 420U1 Motive Water Pumps capable of delivering 66.2m/hr.
According to Derek Wallace, each of the Zone 1 ATEX certified pumps was fitted with an API 682 double mechanical shaft seal system, 37kW electric motors, drive and flexible coupling all mounted on a carbon steel base plate.
VSD for the pumps was provided using four ABB ACS 800 Frequency Inverters.
The DeOiler Chemical Injection Package designed and built by AxFlow is required on the PWP to improve the clarity of the produced water in order to meet governmental specifications for overboard discharge.
The pumps specified for this duty were three Pulsar 25HJ (Duty) and one Pulsar 25HJ (Standby) diaphragm metering pumps.
The unit was supplied with a 750Litre working capacity day tank and instrumentation unit containing flowmeters, check valves and relief valves.
"All four pumps on the de-oiler unit have to achieve flow rates from 0.033L/h to 6.6L/h", says Derek Wallace".
