Gas Processing

INTRODUCTION

Natural or associated gas as well as refinery off gases may contain a number of acidic contaminants, primarily h5S and CO2, inert gases, helium and nitrogen and in rare cases Radon. Removal of these acidic components can be divided into two broad categories, chemical and physical. Sometimes a mixture of chemical and physical solvents are used either in a continuous or batch process.

This Gas Processing training course concentrates on treatment processes in the entire natural gas value chain, from discovery, exploration and transportation through to sales and marketing. The h5S can be converted to sulphur using a modified Claus Sulphur Recovery unit. Each of the various sulphur recovery processes is examined and their chemistry explored in detail. Other techniques that will be covered include Shell’s greener alternative Thiopaq.

This Orbit Horizone Gas Processing training course will feature:

Origins and chemical characteristics of Natural Gas
Gas Treatment Technologies and Processes
Amine Systems and Physical Solvents Design Criteria
Troubleshooting Gas Sweetening and Sulphur recovery Units
All the current Sulphur Recovery Technologies

WHO SHOULD ATTEND?

Industry Newcomers

PROGRAMME OBJECTIVES

Appreciate the Many Aspects of Gas Treating and Sulphur Recovery Processes
Identify the Main Process Steps and Discuss the Key Features of Gas Treating
Demonstrate an Understanding of Many Facets of Amine Sweetening Technologies
Understand the Technology, Chemistry and Thermodynamics of Gas Processing
Evaluate, Monitor, and Troubleshoot Gas Treating Operations

TRAINING METHODOLOGY

This Orbit Horizone Gas Processing training course is highly interactive, applied and stimulating learning experience, with presenter led opportunities to advance ones opinions and ideas through discussions, workshops, class exercises, case studies and examples.

To ensure a thorough understanding of the concepts introduced during the programme a mix of learning methods will be used, including lecture style presentations, open discussion and group work.

PROGRAMME SUMMARY

Gas processing gives a versatile overview of the gas conditioning and processing industry. It is designed for a broad audience and is both participative and interactive. It covers the technology and engineering principles and is recommended for those needing an overview of the industry and the processes and equipment used.

Selection and evaluation of processes used to dehydrate natural gas, meet hydrocarbon dewpoint specifications and extract NGLs will be thoroughly covered and will highlight the issues to the industry on important specifications for gas, NGL and condensate Physical/thermodynamic property correlations and principles to the operation, design and evaluation of gas processing facilities, including practical rule of thumb equipment sizing methods for major process equipment.

In closing the attendees will recognize and develop solutions to a range of operating problems and control issues in gas processing facilities.
