高密度体相纳米气泡对气体水合物生成的促进作用
Promoting effect of high density fluid phase nano-bubbles on hydrate formation
摘要
Abstract
The effects of nano-bubbles on hydrate formation rate and induction period are studied in this paper.In the experiment of the influence of pressure disturbance on the induction period of hydrate formation,it is found that pressure reduction can effectively shorten or even eliminate the induction period of hydrate formation,but instantaneous depressurization does not affect the phase equilibrium characteristics of CO2 hydrate.Through the NanoSight microscale analysis experiment observation,it is found that high concentration nano-bubbles are formed in the proper phase during the depressurization process.The gas-liquid contact area of nano-bubbles is increased,and the high density of nano-bubbles significantly increases the driving force of hydrate nucleation.The experimental results show that the artificially controlled pressure disturbance may avoid the formation of CO2 hydrate,which has practical engineering guiding significance in the marine waste mineral carbon sequestration(CCUS)CO2 project.关键词
