Fuel Gas System-RILS

This is an online version of Fuel Gas System OM-TC2-NXT20100 classroom course

It is divided into 4 modules. Each module should take approximately 4 hours.

Each module contains short quizzes, exercises and videos

Participants in this course will gain an understanding of fuel gas systems used in oil and gas production facilities.  The fuel gas system supplies treated, dry, gaseous fuel for various fired equipment applications within the plant or platform.  The gas can come from a natural gas supply line, off gas from various processes, or a blend of both.  Fuel gas is also used to provide blanket gas to vessels and to supply gas to the pilots on the flare stack.

A fuel gas system is designed to treat gas in order to meet the requirements of the low-pressure equipment such as gas turbine generator, glycol regenerator system, compressor package, purging, and produced water flotation unit.  Participants will learn specifics of a well-designed fuel gas system and how it should remove the offending contamination, ensuring that it is free of liquid and solids and provides the necessary superheating of the fuel gas.

This course will provide participants with an understanding of fuel gas system types, safe operation, monitoring, control, and plant safety management requirements found in the oil and gas industry.
