Carbon dioxide management system and method

Abstract

A carbon dioxide management system and method are disclosed. The carbon dioxide management system, according to one embodiment of the present invention, comprises: a carbon dioxide injection line for supplying, to a carbon dioxide storage, carbon dioxide temporarily stored in a carbon dioxide storage tank; a booster pump, a vaporizing apparatus, and a heating apparatus disposed in the carbon dioxide injection line; and a carbon dioxide recycling means for recycling the carbon dioxide stored in the carbon dioxide storage tank so as to maintain a constant pressure in the carbon dioxide storage tank when the carbon dioxide is supplied to the carbon dioxide storage.

Description

technical field [0001] The present application relates to carbon dioxide management; more particularly, to a carbon dioxide management system and method for efficiently supplying carbon dioxide to a carbon dioxide storage facility. Background technique [0002] Many studies are underway to use carbon dioxide, which is the main cause of global warming, as a gas for compensating pressure during the production of marine aquifers, seawater formations, gas and crude oil, or to store them in space after the production of gas and crude oil. A source is captured and stored. [0003] In order to move the liquid carbon dioxide to the corresponding area, it is expected that pipelines and carbon dioxide transmission lines will be used. Among them, the carbon dioxide transmission line is considered as a solution. [0004] The conventional transportation of carbon dioxide is to use a carbon dioxide transport ship. The carbon dioxide transport ship uses a small-capacity high-pressure con...

Problems solved by technology

However, there are disadvantages such as unnecessary reheating at the time of shipment of liquid carbon dioxide, and in the case of pipelines, the time for loading into the ship becomes very long, and in order to recycle the non-adsorbed carbon dioxide generated at this time, cost a lot

[0020] On the other hand, when the storage pressure of carbon dioxide in the carbon dioxide storage tank is low, the amount of evaporated gas increases relatively, and the ratio of non-condensable gas increases, making it difficult to liquefy it with liquefaction equipment.

[0021] In addition, when the carbon dioxide storage pressure is low, when liquid carbon dioxide is supplied to the carbon dioxide storage place, the suction force of the suction pump used decreases, and there is a disadvantage that the carbon dioxide supply cannot be smoothly realized.
