Dec 01, 2014 · the pump at 200 meters away has a pump rate of 40 meters cubed per hour at atmospheric conditions and 2 meters cubed per hour at it's ultimate pumping pressure which is 0.001 mbar. The pump will have a continuous pressure from the boiler at 200 degrees C and will not be able to reach 0.001 mbar, and there lies my problem.Learn More
In case of steam, as heating temperature increases required operating pressure of the boiler and process equipment goes up. For example, if we want to supply heat at 150 0 C to a distillation column through reboiler. The require steam pressure is around 16 bar (as we need steam temperature between 190 – 200 0 C).Learn More
