SU1223939A1 - Apparatus for setting heat-mass-transfer reactions - Google Patents

Description

The invention relates to chemical technology, more specifically to apparatus for the simultaneous carrying out of chemical processes in the liquid phase and separation of the reaction products by the method of rectification, and can be used in chemical, petrochemical, metallurgical and food industry.

The aim of the invention is to increase the efficiency while simultaneously carrying out a chemical reaction and rectification by increasing the conversion depth of the starting material.

The drawing shows the apparatus, which is tS niv necessary for effective

mass transfer is relatively small height of the liquid on the perforated part of the plate, which makes it possible not to increase or slightly

Dolny cut.

The device has a body 1, plates 2 with vertical partitions 3. overflow thresholds 4, overflow pockets or nozzles 5, perforation b. Perforations can be supplemented with devices that improve the mass, for example caps, valves, visors (non-shown). The perforations are made on the areas of the plates IU: food is a vertical partition and an overflow threshold. The streams are indicated: cnjioiiiHbif.Hi lines - liquid,. dash-ha - steam.

The column works as follows. . .

Leash moves from top to bottom of the pair - S1ShZU up. / Gldkost enters PA each plate 2 through the transfused pipe 5 of the underlying plates; processes can serve, hydrolysis

enters the perforated area of the plate 2 where the chemical reaction takes place, is poured through the vertical partition 3 and falls on the perforated part of the plate (perforation 6), where mass transfer occurs with incoming downstream or complex esters of the lightest product, alcohol.

In addition, the proposed arrangement, performed a dual function, reduces the amount of equipment and energy costs.

through the perforation in pairs, is mixed through the overflow threshold 4 and flows through the overflow pipe 5 to the underlying plate. The pairs, having passed the mass transfer section of the plate, pass over the vertical partition 3 and the liquid in the reaction part of the plate and enter the upper plate through perforations in it.

The arrangement of the perforations on the plates makes it possible to increase the height of the liquid on the reaction non-perforated part of the plate, preserved, and

niv necessary for effective

mass exchange is relatively small height of the liquid on the perforated part of the plate, which makes it possible not to increase or slightly

increase the diameter of the column. By changing the position of the vertical partition on the plate, it is possible to vary the ratio of the volumes of the chemical reaction zone and the rectification zone. Volume

reaction zones can also be changed by changing the height of the partition.

The proposed device allows for chemical processes that are characterized by the occurrence of reverse reactions and for the deep completion of which, therefore, one of the products must be removed from the reaction zone. An example of such

ethers or esters with distillation of the lightest product, usually alcohol.

In addition, the proposed device, performed a dual function, allows to reduce the amount of equipment and energy costs.
