Description
Technical field
The present invention relates to chemical producing system technical field, and in particular to raw material for alkylation molecular proportion control system.
Background technology
Alkyl plant is the alkylation process for the purpose of producing motor petrol, aviation gasoline, uses two class raw materials,
One class raw material is isoparaffin, because alkylated reaction follows carbonium ion mechanism, it is desirable to which alkane has tertiary carbon atom, so only
It can be found in >=C4 alkane；Another kind of raw material is small-numerator olefin, including propylene, butylene and amylene.Butylene is best
Raw material for alkylation, preferably, acid consumption is also minimum for product quality, and the acid consumption of propylene and amylene is almost several times of butylene.In recent years by
Developed faster in producing high-octane rating blending component by propylene dimerization, therefore selection propylene raw material for alkylation is done
Method is fewer and fewer, as amylene itself can as automotive fuel component, almost no one it as raw material for alkylation, therefore
The raw material of alkylation olefin is most importantly butylene, and it includes 4 kinds of isomers：Isobutene, 1- butylene, cis-2-butene and trans- 2-
Butylene.Raw material for alkylation molecular proportion is the important Con trolling index of alkyl plant, and molecular proportion is too high, then iso-butane is superfluous, superfluous
Iso-butane can increase the load of alkyl plant, influence the production capacity of device, reduce the yield of isooctane, increase steam consumption
Amount；Molecular proportion is too low, and system iso-butane can be caused few, influences reaction effect, alkylation is paid reaction increase, reduction isooctane
Quality, causes alkyl plant to be not normally functioning.So raw material for alkylation molecular proportion must be controlled strictly.
The content of the invention
It is reasonable in design, make in view of the defects and deficiencies of the prior art, the present invention intends to provide one kind is simple in construction
With convenient raw material for alkylation molecular proportion control system, it strictly controls the ratio of iso-butane and butylene in raw material for alkylation, really
Protect alkylated reaction to be smoothed out, it is to avoid because molecular proportion controls the bad fluctuation caused, it is ensured that product quality, it is ensured that dress
The length put, peace, steady operation, practicality are stronger.
To achieve the above object, the technical solution adopted by the present invention is：It includes high olefin feedstock tank, isobutane feedstock

Road is connected with No. two pumps, and No. two pumps are connected by pipeline with No. two valve groups, and No. two valve groups are connected by pipeline with No. two flowmeters；
Described isobutane feedstock tank is connected by pipeline with a pump, and a pump is connected by pipeline with a valve group, a valve group
It is connected by pipeline with a flowmeter；The outlet of a described flowmeter and No. two flowmeters is by pipeline with merging pipeline
It is connected after connection with feedstock device.
Further, described merging pipeline is provided with blender.
Further, a described valve group and No. two valve groups are constituted by three stop valves and a straight-through adjusting valve,
Two of which stop valve is in parallel with another stop valve after being connected with straight-through adjusting valve.
Further, described high olefin feedstock tank is high olefin feedstock spherical tank.
Further, described isobutane feedstock tank is isobutane feedstock spherical tank.
Further, a described flowmeter and No. two flowmeters are mass flowmenter.
The technological process of the present invention is as follows：
First, high isobutane feedstock and high olefin feedstock are separately stored in high olefin feedstock tank and isobutane feedstock tank first；
2nd, two pumps are used again（I.e. No. one pump and No. two pumps）Feeding is carried out, and is respectively mounted in the exit of two pumps two valves
Group（I.e. No. one valve group and No. two valve groups）, while installing two mass flows（I.e. No. one flowmeter and No. two flowmeters）, according to
The difference of raw material controls high olefin feedstock and isobutane feedstock by a flowmeter by adjusting a valve group and No. two valve groups
With the accurate metering of No. two flowmeters；
3rd, high olefin feedstock and isobutane feedstock are that feedstock device connects after a flowmeter and No. two flowmeters
After being sufficiently mixed in the pipeline of the merging connect, into process units, it is ensured that raw molecule ratio is 1~1.5:Between 1.
After said structure, the present invention has the beneficial effect that：
1st, the strict ratio for controlling iso-butane and butylene in raw material for alkylation is 1~1.5:1, it is ensured that alkylated reaction smoothly enters
OK, it is ensured that the normal production of device；
2nd, after raw material for alkylation molecular proportion control system comes into operation, raw molecule ratio is controlled well, and being needed according to device can be steady
Surely raw molecule ratio is controlled, it is to avoid because molecular proportion controls the bad fluctuation caused, it is ensured that product quality, it is ensured that
The length of device, peace, steady operation.
