In this study, based on a small high-pressure storage tank rupture and release experimental platform, the boiling phenomenon of liquids containing NaCl impurities during rapid depressurization was investigated, and the mechanism of NaCl-enhanced superheated boiling of the medium was determined. NaCl impurities dissolved in water provide a vaporization core through which bubbles nucleate directly, resulting in a large number of bubbles and enhanced boiling. The degree of NaCl-enhanced superheated boiling does not increase linearly with concentration, and a transition occurs at a saturated boiling concentration of 1 mol/L. Furthermore, this turnaround concentration diminishes with increasing initial pressure under the coupled effect of two factors: increasing number of vaporized cores and increasing pressure. Gas-phase venting is not a necessary condition for the occurrence of superheated flash boiling. Significant superheated boiling can also occur when sodium chloride impurities are present, as liquid phase venting increases the degree of boiling.This paper provides some value for the safe handling and storage of superheated liquids containing NaCl impurities.</div></div>","PeriodicalId":16291,"journal":{"name":"Journal of Loss Prevention in The Process Industries","volume":"97 ","pages":"Article 105695"},"PeriodicalIF":3.6,"publicationDate":"2025-05-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144213293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimized layout of gas explosion energy mitigation measures with efficient, economical and safe can prevent explosion accidents from destroying utility tunnels. The control efficiency of explosion severity of hydrogen-blended natural gas (HBNG) under combined explosion control measures was explored. The control measures (CM) include vent, spray, energy-absorbing materials, and cavity, and their control effects are compared. The results show that the control effect on explosive energy of CM is ranked as central vent > energy-absorbing materials > end vent > cavity. The spray is highly effective in extinguishing flames but has relatively poor suppression effect on overpressure. Under the combined action of reverse stretching at the central vent and the spray water curtain wall, a V-shaped flame is presented, indicating a slowing of flame speed. The combination of the central vent and the energy-absorbing material enhances the dissipation and transfer of the explosion energy, and cavity and central vent hinder the flame propagation under the action of the suction. Under the closed utility tunnel, the fire extinguishing effect of energy-absorbing material and spray is the best, and the effect of energy-absorbing material and cavity is the worst. The optimal strategy for controlling explosion propagation in the utility tunnel is the combination of vent, cavity and energy-absorbing material.
