Abstract: The natural gas processing and receiving platform is equipped with a set of ethylene glycol recovery facility,which is employed for the recovery and treatment of ethylene glycol-rich returned underwater.This facility consists of dehydration,desalination and flash evaporation units.Reboiler is the key equipment of the dehydration unit.During operation,A and B reboilers suffered internal leakage one after another,making the dehydration unit shut down and in turn being unable to produce qualified glycol,which directly led to the shutdown of underwater gas field.On the basis of studying the working principle of each unit of ethylene glycol recovery facility,a series of innovation and renovation schemes are put forward,which ensures continuous production of qualified ethylene glycol when the reboiler is failure.
