I work in refineries as a chemical engineer.
If it is white, then it is steam. Nothing burns in a refinery and produces white smoke.
Black smoke is bad.
Fire may be a flare. Flares are designed to burn excess hydrocarbons within the refinery in a safe way. These excess hydrocarbons might build up within vessels or process units until the pressure exceeds design parameters before they're sent to the flare. So, you might see the flare infrequently. Usually the flare is designed for "complete combustion" so there will be little or no smoke.
