液相流体加剂减阻相关理论及其应用进展

Progresses of theory and application for liquid fluid with drag reduction agent

我国是能源消耗大国,为了响应节能减排基本国策和满足提高生产率的要求,有必要控制能源的消耗采取节能降耗的措施。阐述流体加减阻剂在节能减排方面的广泛应用。通过描述液相流体减阻机理(包括假说的发展),对空调循环系统(如温度、质量分数、减阻剂的混合、应用等方面)进行讨论,油品管道输送中添加减阻剂,可以有效减少全线沿程摩阻损失,降低首站的压力,确保管道运输安全,实现了成本少、迅速、操作简便、有效降低节能消耗且增输的目的。

Our country is energy consumption power,but in response to this basic national policy of energy conservation and emissions reduction and meet the requirement of increasing productivity,it is necessary to control energy consumption energy saving measures.And the characteristic of the economic efficiency of drag reduction agent just can meet the demand of energy saving,this paper describes fluid and subtract retarder is widely used in energy conservation and emissions reduction.First describe the liquid fluid drag reduction mechanism,including the development of the hypothesis,and then the air condition system,such as temperature,mass fraction,the mixture of drag reduction agent,and application are discussed,and then drag reduction from the oil and gas,salt,metal ions,and synergistic agent,and application are discussed,Finally,the oil pipeline in the DRA,can effectively reduce the line friction loss,reduce the first station pressure,to ensure pipeline transportation safety,realize low cost,rapid,convenient operation,effectively reduce the energy consumption and increasing transportation purpose.
