| 摘要: |
| 目的 针对制备乙烯的乙烷原料展开质量要求的探讨,以确定不同用户要求和输送方式对乙烷质量要求的区别,并探讨不同质量指标的检测方法,以期为以天然气为原料生产乙烷的行业提供技术支持。方法 主要参考美国《气体加工工程数据手册》、中国石油天然气集团有限公司企业标准Q/SY 01027-2019《天然气回收乙烷技术指标》对乙烷产品的质量要求,分别对国内气态和液态乙烷产品质量要求和指标进行研究和探讨。结果 乙烷产品宜根据其气态和液态特点分别分为3个等级,乙烷产品来源于天然气,其取样采用天然气取样方法、其主要质量指标采用天然气相关分析方法标准进行检验是适宜的。结论 现阶段国内还没有乙烷产品的国家标准和行业标准,建议有关部门尽快制定乙烷产品国家标准或者行业标准,统一规定乙烷产品质量指标、产品分类、检验规则、交货验收,为乙烷回收项目的实施提供技术支撑,同时也可促进中国乙烷市场和生产体系的建立。 |

| Abstract: |
| Objective This paper discusses the quality requirements of ethane for the production of ethylene to determine the different quality requirements of ethane for different utilization and transportation ways, and further discusses the detection methods of different quality indicators of ethane in order to provide technical support for the relevant industry producing ethane from natural gas. Methods This paper mainly refers to the quality requirements of ethane products in the American Gas Processing Engineering Data Manual (GPSA) and the PetroChina enterprise standard of Q/SY 01027-2019 Technical specification of ethane extracted from natural gas. Based on these two documents, the quality requirements and indexes of gaseous and liquid ethane products in China were studied and discussed intensively, respectively. Results The ethane products may be divided into three classes according to their gaseous and liquid characteristics. Ethane products come from natural gas, so it is appropriate to use natural gas sampling method for sampling and to use related analysis and test standards of natural gas for its main quality determination. Conclusion sAt present, there are no national or industrial standards for ethane products in China. It is suggested that the relevant departments should faciliate the development process of national or industrial standards for ethane products to uniformly regulate the quality indicators, classification, inspection rules and delivery acceptance of ethane products. And then it can provide technical support for the implementation of ethane recovery projects, as well as promote the establishment of China's ethane market and production system. |
