Going ‘green’ with FCC expander technology

New options recover waste gas energy as steam and electricity for plant use

Carbonetto, B., Pecchi, P., GE Oil & Gas

Over the years, petroleum refineries around the world have researched and invested in ways to reduce the amount of waste energy and pollutants produced and released into the environment from their processing operations. The diverse processes used to produce crude oil based products usually require large amounts of electricity to run the various compressors and pumps. Many oil refineries have projects to recapture the energy as part of their cost savings plan and are driven by environmental concerns to reduce pollutants generated by process units.
