Düsseldorf (Germany) March 02, 2016 – GEA recently successfully commissioned a Hybrid Vacuum Ejector System for Bharat Petroleum Corp. Ltd. for the crude distillation unit at its Mumbai (India) refinery. It is the first time this advanced technology has been used on a major refinery in India.
The GEA Hybrid Vacuum Ejector System is fitted with steam jet vacuum pumps and liquid-ring vacuum pumps that together represent the ultimate in highly energy-efficient, vacuum ejector technology. The combination of the two pump types at a well-defined interstage pressure reduces the consumption of the motive medium, power and cooling water. This is achieved by fitting condensers between the jet vacuum pumps to reduce the flow of drawn-off vapors and the motive medium before they reach the liquid ring pump. GEA jet vacuum pumps are able to convey large quantities of gas, operate smoothly and need very little maintenance making them perfectly suited for this application. They are also available in a wide choice of materials so, whatever the medium, corrosion can be reduced or eliminated.
The condensers comply with ASME (Sec. VIII, Div. I), TEMA-R and ASME-U Stamp. The total length of the tubes used in the condensers is 80 km each tube having dimensions of 12.85 m (L) x 2.85 m (W) x 2.95 m (H). The weight of each condenser unit is 65,000 kg and it was transported to site by multi-axle hydraulic trailer, covering a transit distance of 1600 km.
This project illustrates GEA’s leading capability in engineering, manufacturing and delivery of future-oriented, energy-efficient vacuum ejector technology. The system was put into operation in November 2015.
