摘要
目的 通过高含硫天然气中元素硫溶解度的测试数据分析元素硫溶解过程.方法 依据化学反应的物料平衡理论计算物料比例和化学反应产物占比,论证元素硫溶解过程是否适用化学溶解理论.结果 元素硫溶解过程物料比例不满足化学反应的要求,化学溶解占比通常在 10%以下,不适用化学溶解理论.元素硫在H2S、CH4、CO2、含H2S天然气中溶解度随着压力的升高而增大,适用物理溶解理论.结论 高含硫天然气中元素硫溶解过程适用物理溶解理论.
Abstract
Objective Utilizing laboratory-measured data of elemental sulfur solubility in high-sulfur natural gas,the elemental sulfur dissolution process is analyzed.Methods Depending on the material balance theory of chemistry reaction,the proportion of materials and the proportion of chemical reaction products were calculated,and the applicability of chemical dissolution theory to the process of elemental sulfur dissolution was demonstrated.Results The proportion of materials in the process of elemental sulfur dissolution did not meet the requirements of chemical reactions,and the proportion of chemical dissolution was generally below 10%,which did not apply to chemical dissolution theory.The solubility of elemental sulfur in H2S,CH4,CO2,and H2S-containing natural gas increased with increasing pressure,which did apply to physical dissolution theory.Conclusion The dissolution process of elemental sulfur in high-sulfur natural gas is suitable for physical dissolution theory.
