Abstract
The utility model discloses an alkane olefin removing device, and the device comprises a first vapor heater, a second vapor heater, a reactor and a condenser, wherein the first vapor heater, the second vapor heater, the reactor and the condenser are connected in sequence. According to the utility model, a raw material gas is heated by the vapor heaters and led to the reactor, then cooled by the condenser after olefin is removed in the presence of a catalyst, and then olefin removal is finished. The alkane olefin removing device disclosed by the utility model is simple in structure, convenient to operate, very effective in olefin removal, energy-saving and suitable for industrial production.
Description
Technical field
The utility model relates to a kind of alkane except olefin hydrocarbon apparatus.
Background technology
At present industrial except olefin hydrocarbon apparatus be that mixed gas and benzene are placed on the reactor internal reaction, product cools off into the rough segmentation tower through heat exchange, after the gas phase partial condensation of rough segmentation cat head, enter return tank of top of the tower, phlegma is squeezed into the rough segmentation cat head and is refluxed, after non-condensable gas enters the water cooler cooling, gas phase enters the absorption tower, liquid phase flows into the rough segmentation return tank of top of the tower, rough segmentation tower materials at bottom of tower enters the benzene tower after the pump pressurization separates, the non-condensable gas of rough segmentation cat head cooling enter the absorption tower top-down with the absorption agent counter current contact, will wherein recombinate minute absorbs.Tail gas is discharged from cat head, part is made the device fuel, and part is as the deolefination refinery gas, and the material at the bottom of the absorbing tower also enters the benzene tower after the pump pressurization separates, the oil gas of benzene tower steams from cat head, phlegma refluxes, and non-condensable gas advances the rough segmentation tower, and benzene is from lateral line withdrawal function, enter reactor with refinery gas after the heating, as the circulation absorption agent, enter the absorption tower after materials at bottom of tower partly cools off, part is drawn as byproduct.The product purity of this device output is not high, and production efficiency is lower.
Summary of the invention
Goal of the invention: the purpose of this utility model is in order to solve the deficiencies in the prior art, a kind of energy-conserving and environment-protective to be provided, and the output good product quality alkane that but production efficiency is high is except olefin hydrocarbon apparatus.
Technical scheme: in order to realize above purpose, a kind of alkane that the utility model provides comprises the first steam heater, the second steam heater except olefin hydrocarbon apparatus, reactor, condenser, described the first steam heater, the second steam heater, reactor, condenser connect by pipeline successively.
Be provided with the reductibility catalyzer in the described reactor.
Beneficial effect: the utility model heats unstripped gas by steam heater, cause in the reactor, after under catalyst action, alkene being removed, through the condenser cooling, thereby finish except alkene, the utility model is simple in structure, easy to operate, effective except alkene, save energy is suitable for industrialization production.
Description of drawings
Fig. 1 is that alkane removes the olefin hydrocarbon apparatus structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.
As shown in Figure 1, a kind of alkane comprises the first steam heater 1, the second steam heater 2 except olefin hydrocarbon apparatus, reactor 3, condenser 4, described the first steam heater 1, the second steam heater 2, reactor 3, condenser 4 connect successively, are provided with the reductibility catalyzer in the described reactor 3.
During except olefin hydrocarbon apparatus work, unstripped gas is transported to the first steam heater and the second steam heater by pressure reduction, described well heater heats it by steam, heated unstripped gas is transported to reactor 3 by pressure reduction, be filled with catalyzer 4 in the reactor 3, the alkene under the effect of catalyzer 31 in the unstripped gas is removed, and removes gas behind the alkene and is transported to condenser 4 from the outlet of reactor 31 it is lowered the temperature, after gas drops to certain temperature, be delivered to subsequent processing.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the present utility model.
