Dow Chemical Co., Plaquemine (LHC 2),La — United States

Petrochemical in United States. Approximate location 30.31804, -91.23246.

PetrochemicalUnited StatesCO₂ estimate (modelled)

Dow Chemical Co., Plaquemine (LHC 2),La is a petrochemical plant in United States. Its listed capacity is 1,247,000 t of ethylene. 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. It is operated by The Dow Chemical Company. By capacity it ranks #10 among 26 petrochemical plants in United States. It emits about 1,583,070 t CO₂e a year from Climate TRACE. That is 0.28% of the CO₂e from the 1,910 facilities in United States that have an emissions figure in IndustryAtlas.

In context: how this facility compares

At 1,247,000 t of ethylene, Dow Chemical Co., Plaquemine (LHC 2),La is around 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.
