OxyChem operates a billion pound-per-year capacity ethylene cracker at its plant in Ingleside, Texas.

OxyChem incorporated significant energy efficiency features, such as the use of byproduct hydrogen gas as fuel and recovery of surplus heat from the process and flue gas outlet of the cracking furnaces. Another unique aspect of this project is the use of two thermal oxidizers equipped with boilers to combust low pressure gases from process equipment and storage vessels. These thermal oxidizers are designed to provide high emissions control and generate steam from the surplus heat.

OxyChem estimates that it is eliminating approximately 970,000 metric tons per year of total CO2e due to the highly efficient design.
