摘要
本文采用绝热型量热仪的基本原理,设计了氨法捕碳吸收过程反应测量实验系统,提出并实践了以低温水滴定的思路测试氨法吸收CO2过程中反应热效应的研究方法。通过鼓泡实验台,针对质量分数为12%的氨水溶液,测量并计算出氨水吸收CO2至一定碳化度时的反应热,并与理论计算结果进行了比较,相对误差不超过4%,证实了该理论用于此处的正确性,为进一步研究氨法捕碳工艺反应热,进而提出一种可行的低能耗氨法捕碳工艺奠定了基础。
The fundamentals of adiabatic calorimeter and cooling water titration are applied to measure the heating effect in the process of the absorption of CO2 with ammonia solutions.This paper designs a system of absorption experiment,measures and calculates the heat of reaction when the reaction of the absorption reacts to the extent in the bubbling reactor through the experiment with aqueous ammonia of 12wt%.Compared with the result of the theoretical calculation,the relative error is less than 4%,which proves the correctness of the theory used here.In addition,it lays foundations for further studies on heat of reaction in the technology of removal of carbon dioxide by aqueous ammonia,and also for the proposal of feasible programs with lower energy consumption.
