Efficiency of heat transfer equipment
Some fundamental parameters governing the efficiency of heat transfer.
1. Temperature difference - High temperature...
Compressed air is commonly used as a pigging propellant - leading to the term 'air pigging'. Air pigging is so common, thanks to the cheap and readily...
This reboiler, which is essentially a heat exchanger, heats up the liquid. A reboiler may use steam, fire, another hot liquid etc. to provide heat and...
Basically, the reducer and expanders are needed because pump nozzles are smaller than the piping on respective sides.
Why not have smaller piping at suction...
Normally the liquid droplets in the flare/vent network are removed from the gas before entering the flare/vent stack using a flare knock out drum. A knock out...
