Problems solved by technology

However, for such a set temperature, butane or pentane, etc., which are the main components of gasoline vapor, are not liquefied and flow into the adsorption tower as they are. Therefore, the time for gasoline vapor to leak from the adsorption tower is shortened, and there is a switching time of the adsorption tower. shortened subject
Conversely, in order not to shorten the switching time of the adsorption tower, it is necessary to increase the size of the adsorption tower, that is, to increase the amount of adsorbent filled in the adsorption tower, which has the problem of increasing the size of the device.

Abstract

A compact inexpensive gaseous hydrocarbon treating / recovering apparatus capable of efficiently liquefying the gasoline contained in gasoline vapor; and a method therefor. There is disclosed a gasoline vapor recovering apparatus (100) characterized by including a condensation tube (3) for liquefying gasoline vapor; a gas liquid separator (9) for separating the gasoline vapor from the gasoline liquid having been liquefied by the condensation tube (3), provided posteriorly to and on the gas downstream side of the condensation tube (3); adsorption desorption columns (adsorption desorption column (7) and adsorption desorption column (8)) for adsorption desorption of the gasoline vapor having been separated by the gas liquid separator (9), provided posteriorly to and on the gas downstream side of the gas liquid separator (9); a heat medium trapping tank (4) for storage of heat medium adapted to store the heat medium for cooling the condensation tube (3) and the adsorption desorption columns and supply the heat medium to a condensation tube cooling vessel (20) and the adsorption desorption columns; and a refrigerator (6) for cooling the heat medium stored in the heat medium trapping tank (4).

Description

technical field [0001] The present invention relates to an apparatus and method for treating and recovering gaseous hydrocarbons contained in gas discharged to the atmosphere, and more particularly to an apparatus and method for treating gasoline vapor leaked when gasoline is supplied. Background technique [0002] In the existing method of removing gaseous hydrocarbons using an adsorption-desorbent, the gas generated from the exhaust gas source (exhaust gas containing about 40 vol% gasoline vapor) is sent from the exhaust gas supply pipe with a blower or self-pressure. To the condenser, after a part of the gasoline vapor is liquefied in the condenser, the air containing the unliquefied gasoline vapor is sent to the adsorption tower, and the exhaust gas that has completed the adsorption process is discharged from the adsorption tower (in the desorption process) by means of a discharge pipe The top of the adsorption tower after switching) is discharged into the atmosphere as ...
