基于本质安全的新型乙炔溶解度测量方法
Novel method for measuring acetylene solubility based on intrinsic safety
摘要
Abstract
Acetylene is widely used in various chemical industries.However,due to its unstable acetylenic bond,acetylene may explode under pressurized conditions.Therefore,measuring the acetylene solubility in various solvents poses great risks.To safely measure acetylene solubility,a micro solubility measurement device with an inner diameter of 0.8 mm quartz tube encapsulated with about 7 μmol acetylene was designed based on the intrinsic safety strategy of reduction and the solubility measurement principle of static saturation method,which could achieve the gas-liquid mass transfer balance within 1 to 2 h.The acetylene solubility in various solvents was measured with the device at a maximum temperature of 150℃and a maximum pressure of about 0.5 MPa.The average relative absolute deviation between the Henry coefficients measured by the device and in the literature was 5.72%.With the advantages of low acetylene consumption,fast gas-liquid equilibrium speed,low equipment cost and easy operation,the device provides a safe and efficient method for measuring the solubility of hazardous gases represented by acetylene.关键词
