The capture and utilization of CO2 gas are high on the global climate agenda today. Due to the fact that these projects are associated with high costs, today all over the world the practical implementation of such projects is carried out with the participation of states in the form of direct or indirect subsidies. This feature is inextricably linked to the need to quantify the CO2 flux in all process operations of projects. To this end, the paper defines the parameters for CO2 flux quantification, which is carried out by means of flow meters whose error is at the level of ±0.1% to ±0.5% and ±1% to ±4% for fiscal accounting and for operational accounting respectively. The most compliant flowmeters are those based on acoustic methods and on the Coriolis effect, as well as those incorporating differential pressure methods (namely the Venturi principle). In the presence of water in the CO2 flow an acidic environment is formed, which aggressively affects the process equipment and leads to intercrystalline corrosion of metals and alloys, and therefore it is important to control the moisture content, which can be realized with the help of flow meters based on microwave methods. It is also possible to use cross-correlation algorithms to increase the sensitivity of the methods. In cases where it is impossible to provide a moisture free environment, corrosion resistant materials such as carbon-manganese, titanium alloys, austenitic stainless steels, technical ceramic materials, etc., should be used.

CCUS 应用的流量测量
CO 2气体的捕获和利用在当今全球气候议程中占据重要位置。由于这些项目成本高昂，当今世界各地此类项目的实际实施都是在各国以直接或间接补贴的形式参与下进行的。这一特征与量化项目所有流程操作中CO 2通量的需求密不可分。为此，本文定义了CO 2的参数流量量化，通过流量计进行，财务核算误差在±0.1%～±0.5%，业务核算误差在±1%～±4%。最合规的流量计是基于声学方法和科里奥利效应的流量计，以及采用压差法（即文丘里原理）的流量计。在CO 2中有水存在的情况下流动时会形成酸性环境，这会严重影响工艺设备并导致金属和合金的晶间腐蚀，因此控制水分含量非常重要，这可以借助基于微波方法的流量计来实现。还可以使用互相关算法来提高方法的灵敏度。在无法提供无湿环境的情况下，应采用耐腐蚀材料，如碳锰、钛合金、奥氏体不锈钢、工业陶瓷材料等。
