| Abstract: | Trichloroethane was selected as a solvent for the extraction separation of furfural water system. The theoretical results of cross current and counter flow were obtained by simulation calculation. The results show that 1,1,1 trichloroethane is an effective solvent for the extraction process. The recovery of furfural after extraction with n=3 was up to 99% (wt.) and furfural in water layer was reduced to <0.07%. The simulation results will provide theoretical bases for further industrial testing. |
