二氧化碳(CO
2)捕集与封存是减缓全球气候变化的重要手段,新型捕集技术的开发对我国实现CO
2减排目标具有重要意义。本文明确指出传统化学吸收法存在再生能耗高、经济效益低的弊端。相变溶剂在吸收CO
2过程中出现吸收剂–吸收产物分层现象,通过减少解吸溶剂体积的方式进一步降低再生能耗,使得CO
2捕集成本大大降低,为低成本捕集CO
2提供了新思路。
Carbon dioxide (CO
2) capture and storage is an important means to mitigate global climate change. The development of new capture technologies is of great significance for China to achieve the goal of CO
2 emission reduction. This paper points out that the traditional chemical absorption methods have the disadvantages of high energy consumption and low economic benefit. In the process of CO
2 absorption, the biphasic solvent has the phenomenon of absorbent-absorption product stratification, which further reduces the regeneration energy consumption by reducing the volume of desorption solvent. This provides a new way to capture CO
2 at a low cost.

Carbon dioxide (CO2) capture and storage is an important means to mitigate global climate change. The development of new capture technologies is of great significance for China to achieve the goal of CO2 emission reduction. This paper points out that the traditional chemical absorption methods have the disadvantages of high energy consumption and low economic benefit. In the process of CO2 absorption, the biphasic solvent has the phenomenon of absorbent-absorption product stratification, which further reduces the regeneration energy consumption by reducing the volume of desorption solvent. This provides a new way to capture CO2 at a low cost.
