Chevron Phillips Chemical has contracted Technip Energies for a project to enhance the environmental performance of its existing ethylene production unit in Sweeny, Texas. The Sweeny complex, about 50 miles southwest of Houston, is one of the world’s largest single-site ethylene facilities, capable of producing more than 11 million pounds of ethylene daily, translating to about 4.3 billion pounds annually.
The collaboration between Chevron Phillips Chemical (CPChem) and Technip Energies entails the supply of the company’s proprietary low-carbon dioxide (CO₂) emission cracking furnace. This innovative technology is intended to improve fuel efficiency, reduce fuel consumption, and lower CO₂ emissions by approximately 30% from current levels. The design features a unique heat recovery scheme, including combustion air preheat and the first-of-its-kind gas-to-gas primary feed effluent exchanger.
The project further includes the electrification of a major compressor driver, allowing the unit to utilize hydrogen as a fuel source. This capability is expected to contribute significantly to future reductions in the carbon intensity of the existing unit. Techniques such as sourcing renewable electricity, exploring opportunities for electrification and hydrogen firing, and evaluating carbon capture solutions are part of CPChem’s broader strategy to lower the carbon intensity of its operations.
The initiative is aligned with CPChem’s commitment to reducing emissions and advancing their sustainability goals. The company’s in-house climate technology team regularly investigates and studies new technologies and strategies for integration into their existing and future operations.
