H2S and CO2 Removal in the Upstream Gas Sweetening

in Chemical, Oil and Gas

Course Description and Benefits

  • 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, H2S, and CO2 are removed to certain level through a gas sweetening process. The amines (MEA, DEA, MDEA) are the most popular solutions and thus commonly used in many gas 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. 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 trobleshooting common problems affecting proper operation of the unit, in order to achieve the goals of gas sweetening.

Instructor

Hilman Ahmad & Associates

This specially designed course will be conducted by Hilman Ahmad & Associates, an Independent Consultant in industrial oil and gas, member of the Society of Indonesian Petroleum Engineers, who manage the Professional Industrial Oil & Gas Education Center, and has been practicing production operation & safety and corrosion control engineering in Indonesia for more than twenty-five years. He post-graduated from Tokyo Institute of Technology (sponsored by UNESCO) in 1977. He joined in-field-practice program at Nippon Kokan Steel Company & Research Center Kawasaki, Japan for production facility design & construction and corrosion prevention & control in 1983, and collaborated with Cormon Industrial Research Center Brighton UK for on-line corrosion monitoring development in 2000. He has been delivering training course in production operation, maintenance & safety and corrosion control for personnel from Oil & Gas Company and Petrochemical Industry since 1979.
