| 摘 要： | 低温余热的充分利用能够有效提高能源的利用效率、降低生产企业的能耗。本文以含硫天然气净化厂生产过程产生的余热为研究对象,对余热资源品位、余热回收潜能进行了分析和评价。通过对不同的余热发电方案进行分析对比,提出了以有机朗肯循环（ORC）为基础的多品位余热发电方案（MG-ORC）,并对该发电方案进行了热力学分析。借助正交实验手段和多目标优化方法,对不同循环工质条件下MG-ORC发电方案的性能进行了对比分析,结果表明：工质R-600较其余4种工质表现出更优的综合性能,MG-ORC发电系统热效率为17.7%,净输出功率约2600kW。MG-ORC发电方案能够有效合理利用含硫天然气净化厂产生的余热,实现了能源的按质用能和梯级利用。 |

| Abstract: | The full utilization of low-temperature waste heat can effectively improve the efficiency of energy use and reduce the energy consumption. The waste heat generated from the production process of sulfur-containing natural gas purification plants was the object of current study, and the quality of waste heat resources and the potential for waste heat recovery were analyzed and evaluated．Compared with the existing waste heat power generation schemes,a multi-grade heat recovery power generation scheme (MG-ORC) based on ORC was proposed, and thermodynamic analysis of the power generation scheme was conducted．The performance of the MG-ORC power generation scheme under different cycle conditions was compared using the orthogonal experiment method．The results showed that the comprehensive properties of R-600 were the best among other working media. The thermal efficiency of MG-ORC was 17.7%,and the net output power was about 2600 kW．The study confirmed that the MG-ORC power generation scheme can effectively and rationally utilize the waste heat generated from the sulfur-containing natural gas purification plant through cascade utilization of energy． |
| Keywords: | natural gas purification multi-grade waste heat waste heat utilization organic rankine cycle orthogonal experiments cascade utilization |
