Abstract
This paper studies carbon capture and storage based on carbon emission. There are three main technical routes for CO2 emission reduction: pre-combustion capture, oxygen-rich combustion, and post-combustion capture; CO2 separation technology mainly includes: chemical absorption method, solid adsorption method, membrane separation method. CO2 capture needs to be transported to a special place for storage, which can be generally divided into geological storage, marine storage and chemical storage. Future carbon capture research will focus on cost savings and energy savings.
Highlights
The impact of greenhouse gases on global climate is becoming increasingly apparent
The burning of fossil fuels has become the most important source of CO2 emission, and the continuous increase of CO2 concentration in the atmosphere will lead to climate change and global warming
The CO2 capture and separation play an important role in the CO2 emission reduction process
Summary
The burning of fossil fuels has become the most important source of CO2 emission, and the continuous increase of CO2 concentration in the atmosphere will lead to climate change and global warming. Power plants are currently the largest source of industrial carbon, so controlling CO2 emissions from power plants can effectively reduce the concentration of CO2 in the atmosphere. CO2 capture and storage (CCS) is an important way to reduce CO2 emissions, the technology of CO2 capture and storage (CCS) refers to the separation of CO2 from industrial or energy-related emission sources, transportation to certain locations for storage, and long-term isolation from the atmosphere [1]. The current CO2 technology has some limitations; Emission reduction measures have energy consumption in the process of equipment manufacturing, installation and operation, and the utilization efficiency of new energy, such as wind energy, solar energy, biomass energy and low-carbon energy, is still low [2]. CO2 capture can be divided into three technical routes :(1) post-combustion capture (2) pre-combustion capture (3) oxygen-rich combustion [3]
