WebbFractional distillation is the process by which oil refineries separate crude oil into different, more useful hydrocarbon products based on their relative molecular weights in a distillation tower. This is the first step in the processing of crude oil, and it is considered to be the main separation process as it performs the initial rough separation of the different fuels. WebbFor hydrocarbons, viscosity is far higher and conductivity far lower. The high viscosity will lead to the accumulation of heated emulsion around the coil that isolates the mass from further heat transfer because the ΔT is reduced. In theory, we therefore expect a large reduction of heat transfer with the coil in question when used in hydrocarbons. inch or mile crossword
