This 5 day course covers the general design of systems for natural gas handling and treatment from the wellhead to the gas processing plant to achieve marketable products that meet desired product specifications. Gas metering and gas evacuation (pipeline operations) from process plant to sales point.
Duration: 5 days
Location: To be advised
1. To describe and explain gas processing principles of dehydration (water removal) by absorption, adsorption, refrigeration and low temperature separation (JT effect) and basic associated equipment.
2. To describe and explain gas processing in-depth by absorption using glycol and glycol properties. (Pre- Cooling requirements, Dew Point control and related processes). Glycol regeneration including principles of stripping, DRIZO and Coldfinger.
3. To describe and explain process equipment involved for water removal by absorption. (Knock out drums; Contactor – absorber and internals, heat exchangers, re-boilers, pumps, filters and glycol storage).
4. To describe and explain principles of gas metering and types of meter (Measurement Units (MJ, BTU, nM3, scf and conversions).
5. To describe and explain typical gas contracts & sales specifications.
6. To describe and explain gas pipeline operations
NOTE: Objectives for each day will be discussed with the participants and will be verified at closure of each day.
- a) to verify if the objectives for this day were met
- b) to determine if any adjustments need to be made to the program of the following day (if relevant)
Production and processing personnel involved with natural gas and associated liquids to acquaint or reacquaint themselves with gas conditioning and processing unit operations. This course is for production Operations Engineers, Operations Field Supervisors, Facility Engineers, Process Engineers, Design Engineers, operations personnel and others that select, design, install, evaluate or operate gas processing plants and related facilities.

Although the course is aimed at a “Knowledge” (Understand) level, practical exercises and case studies will form an integral part of the learning process.
The objectives and modules of the training course “Gas Processing” are directly linked to the Competence Assurance Programme (CAP) as developed by SOGOS Academy. Skills are selected from the SOGOS Academy skills library and these are translated into the training course curriculum. This approach ensures that each training event will demonstrable contribute to the competence of course participants.
The management framework CAP ensures competence of all employees through:
- the use of a unique set of skills standard to the oil & gas industry
- a common language for skills and competence
- the use of development/job profiles for each employee
- fit-for-purpose training targets
- a control mechanism to measure state of competence
