Abstract
The present invention relates to the method that a kind of waste or used plastics interpolation crude oil or used oil are produced vapour, diesel oil.Mainly be that waste or used plastics and crude oil or used oil are added cracking in the cracking furnace with certain proportion, make gasoline and diesel oil through catalyzed reaction, condensation cooling, rectifying again.The conversion rate of products that has solved the prior art existence preferably is low, thermo-efficiency is low, the problem of complex process.It is a kind of comparatively ideal technology method of handling waste or used plastics, turning waste into wealth, prevent and treat environmental pollution.
Description
The present invention relates to a kind of is main raw material with the waste or used plastics, adds the method that crude oil or used oil are produced vapour, diesel oil.
The processing of waste or used plastics at present is many to be carried out with physical method, and it requires the washability height of waste or used plastics, therefore has a variety of waste or used plastics to handle, and pollutes to environment.It mainly is that waste or used plastics purification, fusion, cracking, cooling, fractionation are made petroleum products that chemical process is handled waste or used plastics, though can turn waste into wealth, conversion rate of products is low, thermo-efficiency is low, the problem of complex process but still exist.
The objective of the invention is at the deficiencies in the prior art part, the method with waste or used plastics system vapour, diesel oil that a kind of technology is simple, thermo-efficiency is high, transformation efficiency is high is provided.
The objective of the invention is to be achieved through the following technical solutions.This production method mainly comprises following process: will remove waste or used plastics behind the impurity and crude oil or used oil and send into thermally splitting in the cracking furnace.The lysate that comes out from cracking furnace enters the reactor, produces paraffins mixture gas under the effect of catalyzer.Above-mentioned paraffins mixture gas is chilled to below 150 ℃ through condenser, isolates a part of diesel oil, and the gas mixture condensation that will not coagulate again is cooled to 25 ℃, obtains vapour bavin mixing oil.Again vapour bavin mixing oil is sent into rectifying tower rectifying, cat head steams gasoline, obtains diesel oil at the bottom of the tower.
The flue gas that above-mentioned cracking furnace, reactor heating are produced enters waste heat boiler, produces for the rectifying tower still steam, and the flue gas that comes out from waste heat boiler passes through chimney emptying.The temperature of reaction of described reactor is 300～350 ℃.Described rectifying tower tower top temperature is controlled at 150 ℃.Described waste or used plastics is meant polyethylene, polypropylene, polyphenyl alkene, polyester etc.Waste or used plastics is 1: 1 with the ratio of the quality of crude oil or waste used oil.
The present invention compares with prior art has following advantage: the fusing of plastics and cracking are all carried out in cracking furnace, have improved thermo-efficiency.Plastics enter reactor again after cracking, improved transformation efficiency.The flue gas that cracking furnace, reactor heating are produced enters waste heat boiler, supplies with rectifying tower steam, has further improved the heat energy utilization rate.Simultaneously, this technology can produce qualified 80# gasoline and-20# diesel oil and lower carbon number hydrocarbons fuel gas, oil yield is more than 70%.In the whole production, no waste discharge, all raw material is fully utilized.
Accompanying drawing is a process flow sheet of the present invention.
Below in conjunction with accompanying drawing in detail the present invention is described in detail.Waste or used plastics such as polyethylene, polypropylene are removed impurity, and the content that makes impurity is sent in the cracking furnace 2 by feeder 1 less than 5%, and used oil or crude oil are squeezed into cracking furnace 2 by pump from opening for feed 11.The cracking in cracking furnace 2 of polymer substance such as polyethylene, polypropylene, these lysates enter in the reactor 3, produce alkane miscellany gas under the effect of 300 ℃ and catalyzer.
Above-mentioned paraffins mixture gas is chilled to below 150 ℃ through condenser 4, takes out a part of diesel oil, and the gas mixture that does not coagulate is cooled to 25 ℃ through condenser 5 condensations again, obtains mixing oil.Mixing oil enters distillation tower 6 and carries out rectifying, and the oily vapour that distills out from the rectifying tower cat head is chilled to normal temperature through water cooler 9, obtains gasoline.At the bottom of the rectifying Tata, obtain diesel oil.With the above-mentioned gasoline that obtains, diesel refining processing, obtain the tank oil of different varieties.
The hot flue gas that cracking furnace 2, reactor 3 heating are come out enters waste heat boiler 7 and carries out waste heat recovery, produces 0.4MP
aAbove steam uses for rectifying tower 6, and the cold flue gas that goes out waste heat boiler 7 is by chimney 8 emptying.The waste residue that cracking furnace 2 produces is slagged tap through slag notch 10.The non-condensable gas attitude hydrocarbon that condenser 5 produces can be used as fuel.
