remedy for high pH of MEG
« on: June 11, 2019, 11:41:55 PM »
pH of MEG used in gas dehydration plant is increasing to around 9.2 for lean MEG and around 8.1 for rich MEG. The reason for increase in pH was found to be presence of salts and Hydrogen sulphide scavenger. Please suggest any chemical to decrease the pH without increasing the chance of corrosion or any remedy which can solve this problem.
