SU17540A1 - Method for continuous distillation of petroleum products in tubular cubes - Google Patents

Description

In some cases, when it is necessary to drive off a large percentage of oil, fuel oil or some other product on tubular cubes, the latter must be significantly overheated in the tubular heater before it enters the evaporator. This leads, on the one hand, to a strong increase in pressure in the pipes, and, with heavy high-boiling oils, also to the risk of cracking. To eliminate the aforementioned deficiencies in raw materials, the proposed method of distillation is added below the evaporator. ,

On the schematic drawing in vertical section shows a diagram of the distillation of petroleum products in tubular cubes according to the proposed method.

The method consists in the fact that waste bins from the evaporator 1 pass through the heat exchanger 2 and enter the intermediate measuring device 3, from which they are sent further to the storage. A part of the sub-steps from the intermediate mernik is taken up by the pump 4 and fed to the discharge line 5,

In the same line, through the heat exchanger 2, the pump b also pumps a fresh product to be distilled, which is heated in the heat exchanger due to the heat of the waste gas. From the injection line, the mixture of both products passes into the tubular heater 7, where its temperature is adjusted to the desired value. Coming out of the tubular heater, the mixture of products enters the evaporator of one or another design, where all the parts of the initial raw product to be distilled evaporate. Underpumps with the pump 4 can be taken directly from the evaporator 1, an intermediate dip tank 3.

The subject of the patent.

A method of continuous distillation of petroleum products in tubular cubes, characterized in that in order to lower the temperature of overheating of the product in the tubular heater, to the raw material being fed to the distillation, an undercooler is added from the evaporator.
