Gas Drying, Sweetening and Processing


This course covers the various aspects of gas process treatments and sulphur recovery. Discussions on the chemistry of acid and sour gas sweetening as well as the processes of sulphur recovery will take place. It will also concentrate on the various processes of removal and recovery of sulphur compounds and the participants will be encouraged to interact through open discussions and group exercises


To enhance the participants' knowledge, skills and abilities necessary to understand sweetening and Sulphur recovery technologies
