Abstract
The utility model relates to a device for lowering alkene from gasoline and producing propylene which belongs to a chemical and physical method device. The utility model consists of a raw material mill furnace, a catalytic reactor and a vapour liquid separator which are connected in series in turn. A raw material inlet a enters the mill furnace through a heat interchanger; an outlet of the mill furnace is connected with the top of a catalytic reactor; a bottom outlet of the catalytic reactor is connected with the heat interchanger and then enters the top of a vapour liquid separator through a cooler. An outlet b of rich gas containing propylene and an outlet c of lowering alkene gasoline are arranged on the top and the bottom of the vapour liquid separator respectively. The internal structure of the catalytic reactor comprises a liquid distribution disk in the entrance, a magnetic ball packing layer and a catalyst bed layer on the top, a magnetic ball packing layer on the lower part, a support sieve plate on the bottom and a liquid lever controlled filter cap in the exit in turn. The utility model has the advantages of a simple design and a reasonable structure. The utility model can be adapted to an oil refining device with flexible adjustment according to demands, thereby contributing to reducing energy consumption of the whole device. Through the device of the utility model, alkene content in the gasoline can achieve an acceptable index directly and propylene products can be produced after intermediate products are separated, thereby greatly improving economic benefits of oil processing.
Description
Technical field
The utility model belongs to the device of chemistry and physical method, the device of particularly a kind of decreasing by gasoline olefin and production propylene.
Background technology
The prior art of decreasing by gasoline olefin mainly is in the catalytic production process of refining of petroleum, by adjusting catalyzer or gasoline being carried out technology such as freshening and realize.However, the reduction of olefin content in gasoline is still very limited, the requirement that does not reach the processed oil that dispatches from the factory, and the increase of green coke amount, and energy consumption is higher.Be not able to, can only be with adding aromatic hydrocarbons or MTBE artificially, so that gasoline reaches qualified product, but its cost is very high, unfavorable market competition.
Summary of the invention
The utility model is intended to solve the deficiencies in the prior art, has designed the device of a kind of decreasing by gasoline olefin and production propylene.Its technological principle is: adopt the static catalytic cracking reaction unit, use the molecular sieve type catalytic cracking catalyst, only long linear alkene, alkane and short-side chain alkene, alkane are carried out selective cracking reaction, generate small-numerator olefin and alkane, so as in operation afterwards with olefin removal.Also can increase production the propylene product of high added value and market shortage simultaneously.Its technical scheme is: the device that has been followed in series to form decreasing by gasoline olefin and production propylene by raw materials furnace and heating, catalyticreactor and vapour liquid separator.Wherein: feed(raw material)inlet a enters process furnace through interchanger, and furnace outlet connects the top of catalyticreactor, and the outlet at bottom of catalyticreactor connects interchanger, enters the top of vapour liquid separator again through water cooler.There are pneumatic outlet b, the bottom of being rich in propylene that the olefin gasolines of falling outlet c is arranged at the top of vapour liquid separator.The internal structure of catalyticreactor comprises liquid-distributing disk, top magnetic ball packing layer, beds, bottom magnetic ball packing layer, bottom support sieve plate and the outlet liquid level controlled filter cap of ingress successively.Water cooler is to replace with wet air cooler, dried air cooler, dried wet combination air cooler or any of water cooler.
Decreasing by gasoline olefin of the present utility model and produce the device simplicity of design of propylene, rational in infrastructure, the oil refining apparatus that adapts to prior art can be adjusted its operation flexibly by demand, helps reducing the energy consumption of single unit system.Particularly in refining of petroleum,, can make olefin content in gasoline directly reach qualified index by device of the present utility model.Simultaneously, to middle product after separating, but the production propylene product has greatly improved the oil product economic benefit of processing.
Description of drawings
Figure of description is the utility model decreasing by gasoline olefin and the structural representation of producing the device of propylene.
