Gas treating membrane systems provide a safe and efficient option for water vapor and carbon dioxide removal from natural gas, especially in remote locations. Membrane systems are extremely adaptable to various gas volumes, CO2 concentrations, and/or product-gas specifications. With increasing demands to natural gas in Indonesia, sour gases are being tapped for utilization after purification. But, the natural gas that is transported to the fuel market must meet legal and safety requirements; it must be non-toxic, non-corrosive and safe to environment. For that reasons, gas conditioning or specifically gas treating is a very important step in gas processing scheme. H2S, and CO2, are removed to certain level through a gas sweetening process. There are many processes available. The amines (MEA, DEA, MDEA) are the most popular solutions and thus commonly used in many fields



This course is designed as an effective practical shortcut to understand the amine sweetening process and all features and problems encountered in amine plant operations for engineers, operators, technicians, and anyone who involve or responsible  in H2S and CO2 removal.

The course content and approach are designed to suit participants of different background and different position in the company. It will be delivered as a to-the-point explanation by a professional instructor, utilizing an easy-to-understand examples and illustrations, especially the actual findings in Indonesia.


By attending this course, participants are able to broaden or reshape their knowledge on the related subjects of his or her area of responsibility, learn more about the principles of amine sweetening, identify and discuss the function of each component used in the process, and trace process flow through a typical amine unit, discuss and consult their specific problems they are about to bring to the class, and share experiences with others.

After completion of this course, participants will understand how each component in the unit operates, the effects of process variables, what and how to monitor the unit and make necessary adjustments, what and how to perform routine maintenance, and troubleshooting common problems affecting proper operation of the unit, in order to achieve the goals of gas sweetening.
