Thermodynamic cycle construction method adopting chemical absorption carbon capture technology

Abstract

The invention discloses a thermodynamic cycle construction method adopting a chemical absorption carbon capture technology. The thermodynamic cycle construction method is a thermodynamic research method comprises the following steps: completing construction of thermodynamic cycle in the order of ''physical properties, process, cold and heat source, and cycle'', and investigating cycle energy efficiency. The method provided by the invention takes the chemical absorption carbon capture technology as an example, and applies the thermodynamic research method to the novel technical field of carboncapture; and as a ''quantitative ruler'' based on thermodynamic thoughts, thermodynamic cycle can analyze performance of the carbon capture technology, judge maturity of the technology through secondlaw efficiency, and effectively explore the energy saving potentiality of the carbon capture technology.

Description

technical field [0001] The invention relates to the thermodynamic research field of carbon capture technology, in particular to a thermodynamic cycle construction method using a chemical absorption carbon capture technology. Background technique [0002] With the development of industry and the huge consumption of fossil energy, the global CO 2 The average concentration has exceeded 415ppm. A global average temperature rise exceeding 2°C will inevitably lead to global natural environmental disasters, such as melting glaciers, rising sea levels, and species extinction. The United Nations Intergovernmental Panel on Climate Change (IPCC) proposed that to control the global average temperature rise within 2°C, efforts must be made to triple the current emission reduction efforts. According to the U.S. Energy Agency (IEA), improving energy efficiency, using green renewable energy and carbon capture technology are currently three major emission reduction strategies. Carbon capt...

Problems solved by technology

[0008] In summary, it can be seen that the existing relevant patents cannot achieve the goal of developing an ideal thermodynamic research method as described above. The efficiency analysis model of chemical absorption carbon capture needs to be developed to the cycle level for in-depth analysis.
