Rubber is firstly sliced by rubber refining machine and then sent to sol cylinder to mix sol with gasoline. The sol is then emulsified and modulated and pumped to the emulsion tundish. The rubber solution dissolved in gasoline is fed from the top of the distillation column and distilled by steam heating. The light component of gasoline is heated to form a gas phase. The gasoline gas is mixed and cooled by cold water in the oil and gas cooler.
