1. Each set of unit is comprised of the following eight parts: a. Reboiler b. Fractionating tower c. Pressure release device d. Central electric control system e. Condensation system f. Fuel gas heating system (exhaust treatment system) g. Air heater h. Flue dust collecting system 2. Domestic origination: a. The whole set installment's production entire process is moves in the smokeless tasteless environment, the environmental protection effect is good. b. The pressure release device operates through water circulation, which greatly improves the security of the system. c. The release of pressure during the production dramatically increases the output within certain time and meanwhile improves the quality of oil. d. The heating system adopts hot air heating technology, which improves the safety performance of production and heating efficiency. e. Highly effective fuel gas heating system. In refinery process, when is heated up after the gas amounts to 150 degrees Celsius, will produce the gas which the massive normal temperature atmospheric pressure cannot liquefy --- Methane to butane. These gas after we design specially in gas nozzle full combustion, has the massive energies, saved the energy greatly. f. Flue dust removal system. Has the bidirectional water impact type tornado dust removal room, May guarantee that the flue export the emissions achieves the state-level emission standard
