GEA Westfalia Separator Group is a company of GEA Group Aktiengesellschaft, which is a leading systems provider for the food processing industry and a range of other process industries.
GEA Westfalia Separator Group, founded in 1893, is a technology leader for mechanical separation and, backed by 50 sales and service companies, offers cutting-edge centrifugal separation technology by means of separators and decanters. The value-adding solutions for the food and beverage industry; renewable resources; the marine, oil, gas and energy sectors; as well as chemicals, pharmaceuticals and environmental technology, are setting standards in process efficiency and availability. The innovative strength of the company is based on the installation of products in over 3,000 different procedures and processes.
Demands and requirements for processing rigs and FPSOs are increasing. Operating reliability, weight and space requirements are major parameters. GEA Westfalia Separator supplies plug-and-play processing systems that comply with even the most stringent environmental requirements, and feature the latest space, weight and energy-saving designs. Its centrifuges handle continuous liquid-liquid-solids separation in a wide range of upstream and downstream applications in the oil and gas industry.
Its contribution is to help you protect the fragile environment and to maintain the "zero-discharge philosophy". Thus, GEA Westfalia Separator has developed a complete environmental system that reduces the discharge to the sea to a minimum. Its centrifuge for the purification and dewatering of mineral oil was first applied in 1907. Today, 10,000 of the company's centrifuges take care of the reliable and economic treatment of fuel and lube oils, as well as oily and watery sludge.
The separators are vertical-bowl high-speed centrifuges up to 10,000G that are primarily used for the clarification and separation of liquids with and without solids content. The throughput capacities range from 50-250,000L/h; a comfortable spectrum that accommodates the units for all process steps of separation technology. When the solids content in the suspension is too high, it's time to call in the decanters. They are often installed upstream of a separator and achieve high-clarification efficiencies and maximum dewatering.
Special features of the separators and decanters include high-separation efficiency; no impact from ship/platform movement; achieve lower than 5ppm oil in water; IMO MEPC 107(49) approved; reduced need of chemicals; gas-tight design available; self-cleaning or manual centrifuges; nozzle centrifuges; ex-zone 1 and 2; ATEX approved; compact and robust design; and plug-and-play systems.
The new decanter generation from GEA Westfalia Separator for the treatment of drilling mud and barite recovery has been consequently optimised to meet all the requirements of heavy-duty offshore environments. Features of the rigMaster include stainless steel for all product-contacting parts; duplex bowl and scroll; external planetary gears; and tiles or hard-faced scrolls make it an extremely robust working hose. Due to the pillow-block design, hinged hood and modular concept, the decanter is easily and conveniently accessible for fast service and repair.
The GEA Westfalia Separator summationdrive always provides full torque across the entire regulation range; always full torque means always full performance. On top, the summationdrive manages with only the power that is actually needed, braking effects do not occur. Accordingly, conversion losses are reduced to a minimum; you also save belt drives, shaft loads and construction space. In the version used for higher differential speeds, the drive combines the outputs of the primary and secondary motor (summation) and thus minimises energy consumption.
Automatic torque monitoring and control is standard for all the drive systems. The summationdrive automatically ensures constantly high-solids concentrations even for fluctuating feed conditions. It achieves minimum residual humidity in the solids discharge of the decanter and permits maximum solids discharge volume by means of minimum differential speeds. The gear transmission ensures a normal motor speed even in conjunction with minimum differential speeds, and thus ensures good cooling.
Design features of the drilling-mud decanters include the deep-pool concept for enhanced performance by optimised process setup; tungsten carbide tiles or hard-faced scroll for longer operational life; duplex bowl; stainless-steel wetted parts; stainless-steel hood; welded rigid frame; pillow-block design for easy and fast service; energy saving, highly flexible and rigid drive system for maximum solids concentration; and torque monitoring for safe operation.
