Embodiment Construction

[0009] The present invention will be described in detail below in conjunction with examples. The protection scope of the present invention is not limited to the embodiments, and any changes made by those skilled in the art within the scope defined in the claims also belong to the protection scope of the present invention.

[0010] The method for sequestering carbon dioxide in the deep sea of ​​the present invention comprises the following steps: 1. Collecting carbon dioxide, the collected carbon dioxide includes carbon dioxide produced by calcining limestone in a partition wall rotary kiln and carbon dioxide released by oxidation of toluene in the production of caprolactam by toluene method. Use a dry ice maker to pressurize and cool down to make dry ice and store it in a storage tank. The energy used by the dry ice making machine to pressurize and cool down to make dry ice is solar energy, wind energy and electric energy when electricity consumption is low. 2. The dry ice is...

Abstract

The invention relates to a method for storing carbon dioxide in deep sea.The method includes the steps of firstly, collecting carbon dioxide, conducting pressurizing and cooling through a dry ice making machine to make dry ice to be stored in a storage tank; secondly, conveying dry ice to a deep sea area suitable for storage through land transportation and sea transportation modes; thirdly, melting dry ice into liquid carbon dioxide through a high-pressure pump, and conveying liquid carbon dioxide to a seabed 600-10000 m deep through a conveying pipe; fourthly, keeping 5-20 %(wt) of the storage amount of liquid carbon dioxide in a sea transportation ship after conveying carbon dioxide to deep sea.By means of the storage energy and phase-change release energy of carbon dioxide, by driving carbon dioxide collecting, compressing, conveying and injecting equipment, carbon dioxide is gathered, dry ice is prepared and then conveyed and injected to the seabed, green energy is sufficiently used, energy storage and utilization are effective, the cost of the carbon dioxide storage process is reduced, and the atmosphere pollution and greenhouse effect can be easily reduced.

Description

technical field [0001] The invention belongs to the technical field of controlling greenhouse gas effects, and relates to a method for sequestering carbon dioxide, in particular to a method for sequestering carbon dioxide in deep sea. Background technique [0002] The biggest scientific discovery in the 20th century is the discovery of human beings' survival crisis. The deterioration of the global environment has become the primary problem threatening human survival. CO in the Earth's atmosphere 2 Rising concentrations of GHGs and other greenhouse gases enhance the greenhouse effect, leading to climate change. Due to the global dependence on fossil fuels, carbon dioxide emissions from industrial production and human life are increasing, and the resulting greenhouse effect is seriously threatening the earth's environment. Carbon dioxide capture and storage technology is to collect carbon dioxide from large-scale emission sources and store it in an appropriate place, so as t...
