General operating problems and their solutions of natural gas sweetening process (amine system)‎

Abstract EN

The paper presents general operating problems and some important trouble shootings which are concerning and involved with the operation and performance of the different equipment of the gas sweetening plant by using amine system.

The trouble shooting deal and diagnosis of the problems encountered during plant operation with the main equipment like high and low pressure, level and differential pressure in the absorber and stripper as well as the high and low temperature of the lean solution besides the reflux pump shut down and low and high level alarm failure.

Experimental work was done, it was seen that the optimum concentration of MDEA is 50 %, the optimum mole of steam to acid gas ratio is 1.5, and it was recommended to maintain the pH value for lean amine at a range of 7.1-8.0 by improving the stripping process.
