Introduction

TRAINING DESCRIPTION

Throughout this course, sessions will pro­vide opportunities for the trainees to get familiar with the fundamentals and prac­tical aspects of natural gas processing. Further, the course will acquaint the trainees intensely with the most recent technologies applied in the field of condensate recovery & fractionation through delivering real-life case studies to achieve marketable products that meet desired product specifications.

Emphasis is placed on offering plant operating personnel an improved understanding of the condensate recovery & fractionation techniques and equipment used.

Typical equipment and facilities that are found in typical natural gas processing operations will also be discussed including compressors, vessels, and relief, flare and safety systems. This improved understanding of plant process operations and effective process plant surveillance techniques will lead to an increased ability to achieve optimum, economical operating performance.
