Rainbow Refraction In Spraying Liquid At Petroleum Coke Terminal

Texas City, Texas, USA

A spray of water forms a rainbow at a petroleum coke storage facility, which accepts this waste product from the nearby oil refineries. The water is sprayed to control airborne dust. Petroleum coke or “petcoke” residue from oil refining can be purified for use as electrodes in electric arc steelmaking furnaces and anodes and cathodes in aluminum smelters.
