When screening solvents for carbon capture, a large amount of property data for each solvent in the CO₂-loaded state is required. In this paper, a novel experimental method is proposed that involves modifying a wetted wall column in order to simultaneously measure the absorption rate, viscosity, pH, and heat of reaction of carbon capture solvents while the CO₂ loading is increased continuously. The proposed method was applied to 30 wt% aqueous monoethanolamine and 30 wt% aqueous piperazine as solvents and found to produce measurement results that matched well with literature data.

同时连续测量二氧化碳捕获溶剂的吸收速率，粘度和反应热的实验方法

当筛选用于碳捕获的溶剂时，需要每种负载有CO _2的溶剂的大量属性数据。在本文中，提出了一种新颖的实验方法，该方法涉及对湿式壁柱进行改性，以便在连续增加CO ₂负载的同时测量吸收率，粘度，pH和碳捕获溶剂的反应热。将该方法应用于30 wt％的单乙醇胺水溶液和30 wt％的哌嗪水溶液作为溶剂，发现其测量结果与文献数据非常吻合。
