Natural Gas Processing on Onshore Facilities

Natural Gas Processing on Onshore Facilities Training Course

This intensive three-day course is designed to address the operation and control of natural gas processing equipment for onshore fields. Gas processing onshore involves the gathering of the gas using field or nodal compressors before dehydrating, compressing and either re-injecting, storing in caverns or exporting via a pipeline. Carbon Dioxide may be removed from the gas using membrane separation and further removal of heavier hydrocarbons may occur by dew-point conditioning. The field/nodal compressors are usually screw or reciprocating units with centrifugal compressors used in the larger gas plants. Reciprocating compressors, screw compressors, gas dehydration (using glycol units),  and hydrocarbon dew-point conditioning will therefore be covered in detail. Centrifugal gas compressors and acid gas removal using membrane separation will be briefly touched depending on the interest of the delegates attending each course. Each topic will be covered using a mix of short lectures, videos, dynamic simulation models and group workshops. 

Suitable for: This course is designed for participants who are involved with the operation of onshore natural gas production either working in the field or at the gas plant. Operations personnel who have some level of responsibility for the operation, control or management of the gas processing facilities will benefit most from this course.
