Introduction

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.

Objective

Upon successful completion of this course, the delegates will be able to:

• Demonstrate knowledge and under­standing of the principles of natural gas industry.
• Select and implement most adequate techniques for condensate recovery & fractionation.
• Relate the gained knowledge in the area of natural gas utilization to real-life cases.
• Apply troubleshooting to technical dif­ficulties encountered in the field of specialization.

Audience

The program is ideal for personnel involved in gas plant process operations, troubleshooting, process engineering, and technical services as well as others providing services to the gas industry, should also find this program beneficial.
