摘　　要：本文旨在研究某炼油厂15万t/a MTBE装置的节能降耗,以提出多种创新的方案来改善该装置的能耗和经济效益。首先,对MTBE生产过程中能耗的各项来源进行了研究,包括前期处理、反应和分离等环节。然后,提出了一系列的节能措施,并进行了实验验证。在工艺前期,调整产品精制水洗操作,降低了碳四中的杂质含量,有效减少了在MTBE生产过程中的能耗。同时,优化了醇烯比,最大限度促进异丁烯和甲醇的反应,从而减少了能耗。此外,通过降低催化蒸馏塔和甲醇回收塔的蒸汽用量,并进行余热回收,成功实现了预期目标。与传统MTBE装置相比,该方案显著降低了能耗,并提升了经济效益。针对不同操作条件进行了综合实验和模拟研究,以评估各个工艺参数对能耗的影响。这些措施不仅能够降低能耗、改善经济效益,还为其他炼油厂类似装置提供了有价值的创新借鉴。This paper aimed to study the energy saving and consumption reduction of a 150,000 t/a MTBE unit in an oil refinery,in order to propose a variety of innovative schemes to improve the energy consumption and economic benefits of the unit.Firstly,it studied various sources of energy consumption during MTBE production,including pre-treatment,reaction and separation.Then,it proposed a series of innovative energy-saving measures and carried out experimental verification.In the early stage of the process,the product purification washing operation was adjusted to reduce the impurity content in carbon 4,and effectively reduced the energy consumption in the production process of MTBE.At the same time,it had innovatively optimized the alcohol-ene ratio to maximize the reaction between isobutylene and methanol,thereby reducing energy consumption.In addition,by reducing the steam consumption of the catalytic distillation tower and the methanol recovery tower,and recovering the waste heat,the expected goal was successfully achieved.Compared to conventional MTBE units,the solution significantly reduces energy consumption and improves economic efficiency.In summary,comprehensive experiments and simulation studies were carried out for different operating conditions to evaluate the influence of each process parameter on energy consumption.These innovative measures can not only reduce energy consumption and improve economic efficiency,but also provide valuable innovation reference for similar units in other refineries.
