Description
Technical field
The utility model relates to oil shale retorting oil refining technical field, is a kind of retrieving arrangement of microwave adsorption desorption oil shale distillation gas lightweight oil.
Background technology
Oil shale distillation, temperature required by being heated in the environment of resinous shale as isolated air, make petrologen generation pyrolytic reaction, generate destructive distillation product-shale oil and destructive distillation coal mine gas, shale oil not only directly as the liquid fuel for marine turbine, also can be passed through rectification process and produces the liquid fuel such as gasoline and diesel oil.At present, in industry, shale oil recovery generally adopts the method for destructive distillation oil gas being carried out to condensation separation, destructive distillation oil gas is carried out cooling process, shale oil liquefy is separated out, remaining as noncondensing methane gas.Therefore, the temperature that carbonizing gas is cooled is lower, the shale oil that condensation obtains is also more, oil recovery rate is also higher, but the gas tolerance needing condensation in distillation process is very large, and along with the reduction of unit methane gas oleaginousness, condensing temperature also reduces, need the cold paid also to increase, certainly will will consume mass energy.Consider from macroeconomic in current industry, shale oil recovery technique outlet temperature is controlled at 40-60 DEG C, if temperature is low again, certainly will will consume the more energy, increase oily harvest originally.This directly causes, in destructive distillation end product coal mine gas, not reclaiming lightweight oil phenomenon containing a large amount of.On the other hand, shale oil belongs to the mixture of multiple hydrocarbon polymer, known from its physicochemical characteristics, vapor pressure is higher at normal temperatures for its light constituent (solar oil), has the feature of highly volatile, is easily entrained in destructive distillation coal mine gas, be difficult to collect, form the phenomenon of gas band oil.Field data show, the large-scale destructive distillation oil refining enterprise in domestic northeast, in destructive distillation coal mine gas, oleaginousness is at 20-25g/Nm
3, it singly overlaps destructive distillation device, and outlet gas tolerance is approximately at 70000-80000Nm
3/ h, in the gas free air delivery of 24 hours, just has the lightweight oil of 36 tons (solar oil) do not reclaim and discharge with gas tail gas nearly.According to average statistics in industry, in the destructive distillation coal mine gas of current resinous shale enterprise discharge, oleaginousness is about 15-20g/Nm
3, so a large amount of high-quality fuel oils is not retracted, and while forming resource huge waste to oil refining enterprise, also there is serious pollution, cause potential disaster hidden-trouble especially to production environment to environment, harm is produced and personnel safety.
