Lewa: Safe pumping of sour crude oil

Thursday, May 7th, 2015 von admin

SauerölpumpeCritical applications of conveying mixtures of acidic hydrocarbon/water to the washing system are a challenge for any pump manufacturer. This was also the case in one recent project Lewa handled in the Emirate of Abu Dhabi. Lewa have designed and supplied 16 pumps to a major construction company in Abu Dhabi specifically designed to handle this critical application. Two processes required to pump

  • liquid hydrocarbons from the flare knock-out drum or the blow-down drum respectively and
  • convey the acidic hydrocarbon/water mixture back into the oil line to the washing system

Since the differences in these two processes are only minor, it was possible to supply 16 mechanically identical pumps of the Ecoflow series, driven by 55 kW electric motors.

Andritz: Dewatering flooded mine tunnels in South Africa

Thursday, July 17th, 2014 von admin

South Africa is currently dealing with the problem of acid water because underneath the old gold mining city of Johannesburg is a lake which contains heavily contaminated water, which spreads horizontally and vertically into the abandoned pits of the former gold mines.  Meanwhile, the water line has reached a critically high level, as determined by the specialists from Andritz Ritz, which was given the first order to drain the mine water in 2010. The execution of the project was delayed by four years however, and it was only in spring 2014 that two powerful submersible motor pumps were installed in the middle of Johannesburg city centre, in the so-called “Central Basin”, with each pump capable of bringing 1,500 m³/h of water to the surface.
