A channel is made in the chamber for connecting its cavity by means of a flexible pipe with a branch pipe with a irrigation pipe, and a chimney of a jet of cold irrigating liquid is installed in the chamber. 1 hp ff, 3 sludge, WITH with

Description

The invention relates to the storage of petroleum and petroleum products and can be used in the petroleum, petrochemical, and petroleum refining industries.

The purpose of the invention is to reduce the loss of oil products from evaporation. In an installation for the utilization of vapors in storage tanks for oil and oil products, including tanks, a receiving pipeline connected to the lower part of the tanks, irrigation pipe to a distributor, a circulation pump connected to the suction pipe to the receiving pipe, and the discharge pipe to the irrigation pipe located in the upper parts of the tanks, and the gas equalizing pipe connected by nozzles with the upper part of the tanks, and it is equipped with After the circulating pump, the ejector, to which the gas equalization pipeline is connected, each distribution device is made in the form of a metal chamber having a perforation on the surface opposite to the bottom and on the side surfaces, and is placed on the float in the form of a closed container, in the center of the bottom there is an opening for connecting the chamber by means of a flexible hose with a branch pipe with irrigation pipe, and in the switchgear above the nozzle there is installed a chipper of a cold irrigating well jet liquids, which provides effective cooling of oil products in the upper layers of the tanks, which in turn leads to a decrease in the temperature of the gas space of the tanks of the elasticity of saturated vapors and, consequently, to a reduction in the loss of oil products.

FIG. 1 shows a plant for the disposal of vapors in tanks; in fig. 2 - switchgear on the float; in fig. 3 is a view A of FIG. 2

The installation for vapor utilization consists of atmospheric tanks 1, receiving pipe 2, circulating pump 3, connected by suction pipe 4 to receiving pipe, and discharge 5 to irrigating pipe 6, ejector 7, irrigating pipe 6 with distribution device 8 installed on the float 9. Switchgear 8 is made in the form of a metal chamber, the top 10 and side 11 of which are perforated. In the center of the float and in the bottom 12 of the chamber there is an opening 13 for introducing a cold irrigating fluid into the chamber of the distribution device 8 by means of a flexible pipe 14 with a nozzle 15 connected to the irrigation conduit.

In the upper part of the lateral surface of the dispenser 8, there are also outlet openings.

In the upper wall 10 above the inlet 13 there is a bump 16, having a concave surface. The installation is also equipped with gas equalization pipe 17.

The installation for vapor recovery works as follows.

Oil and petroleum products enter tanks 1, in which the temperature of the gas space at the top of the tanks is reduced.

From the lower cold zone of the tanks 1, the petroleum product is pumped by the circulation pump 3 through the holes 13 through the receiving pipe 2, then to the distribution device 8 installed on the float 9 and then through the holes in the chamber walls it flows back into the upper part of the tanks 1.

In the event of the expiration of petroleum products through the ejector 7, they are extracted (aspirated) through the gas equalization pipeline 17 to heat the gas mixture.

As a result of mixing with cold oil in the ejector 7, a part of the sucked gases is condensed and the mixture thus formed flows together with the oil to the liquid mirror in the tank 1 through the distributor 8 in the form of a cold irrigating liquid, and the excess energy of the jet is extinguished by the baffle 16.

The unit provides effective cooling of the upper layers of petroleum products.

in tanks, which leads to a decrease in the temperature of the gas space of the tanks, the elasticity of saturated vapors and, consequently, a reduction in the loss of oil products.
