In context: how this facility compares

At 331,000 t of ethylene, Westlake Petrochemicals Corp., Calvert CityKy. is below the median petrochemical plant in United States (1,134,000 t of ethylene). Subsector: petrochemical-steam-cracking. As petrochemical plant, it requires high process heat (typically 300–800°C) for its core industrial operations, supplied by boilers, furnaces or direct combustion. Petrochemical plants crack hydrocarbons at very high temperatures to produce ethylene, propylene and other building-block chemicals — one of the most heat-intensive industrial processes.
