The method for reducing nickel plating in the nickel carbonyl distillation process is easy and convenient to operate and obvious in effect. Through detection, the nickel plating speed of reboiler heating tube nests is obviously reduced.
Description
Technical field
The present invention relates to chemical technology field, be specifically related to a kind of method reducing the nickel plating of nickle carbonoxide rectifying.
Background technology
At present, it is shrend alloy that carbonyl process produces the raw material used in nickel powder process, containing ferro element in shrend alloy, can produce the mixing liquid of nickle carbonoxide and iron carbonyl in building-up process.Nickle carbonoxide is separated with iron carbonyl by usual employing rectifying, and easily there is decomposition reaction when being above the boiling point in nickle carbonoxide, metallic nickel is deposited in rectifying tower reboiler, causes rectifying tower reboiler to block, need to change rectifying tower reboiler after running certain hour.Usually delaying the method that nickle carbonoxide decomposes deposition nickel plating is reduce the temperature and pressure of rectifying as much as possible, but due to the character of nickle carbonoxide, nickle carbonoxide decomposition course is inevitable, and the work changing rectifying tower reboiler consumes a large amount of time, man power and material.
Summary of the invention
For above-mentioned problems of the prior art, the invention provides a kind of method reducing the nickel plating of nickle carbonoxide rectifying, the method technological process of reduction nickle carbonoxide rectifying of the present invention nickel plating is simple, effectively can reduce the sedimentation rate of nickel on reboiler heating tubulation.
Above-mentioned purpose is realized by following proposal:
Reduce a method for nickle carbonoxide rectifying nickel plating, it is characterized in that, the method comprises the step passing into CO gas in rectifying tower reboiler.
According to the method for above-mentioned reduction nickle carbonoxide rectifying nickel plating, it is characterized in that, the inlet amount of rectifying tower is 5 ~ 10:1 with the mass ratio of the CO gas passed in rectifying tower reboiler.
According to the method for above-mentioned reduction nickle carbonoxide rectifying nickel plating, it is characterized in that, the temperature out of rectifying tower reboiler is 39-44 DEG C.
According to the method for above-mentioned reduction nickle carbonoxide rectifying nickel plating, it is characterized in that, the pressure of rectifying tower is 40-50kPa.
Beneficial effect of the present invention:
The method of reduction nickle carbonoxide rectifying of the present invention nickel plating, easy and simple to handle, successful.After testing, the nickel plating speed of reboiler heating tubulation obviously slows down.
Embodiment
The method of reduction nickle carbonoxide rectifying of the present invention nickel plating, CO gas is passed in rectifying tower reboiler, and by the flow of controls CO gas, the temperature of rectifying tower reboiler and the pressure of rectifying tower, realize the object reducing reboiler nickel plating, prolongation reboiler life cycle.Wherein, the inlet amount of rectifying tower is 5 ~ 7:1 with the mass ratio of the CO gas passed in rectifying tower reboiler, and the temperature out controlling rectifying tower reboiler is 39-44 DEG C, and the pressure of rectifying tower is 40-50kPa.
The CO gas of certain flow is passed in rectifying tower reboiler, nickle carbonoxide in rectifying tower reboiler and iron carbonyl liquid are mixed with CO gas, simultaneously, reboiler can heat carbonyl mixing liquid and CO gas simultaneously, CO gas drives mixing liquid to move upward, accelerate the travelling speed of mixing liquid, and reduce the duration of contact of mixing liquid and hot face, thus reduce the decomposition settling velocity of nickle carbonoxide at heating surface.
