炼油化工是高能耗高污染产业,在降低能耗、保护环境、实现节能减排目标过程中担当着不可替代的重要角色。近年来,世界许多大型石油石化公司为提高综合竞争力,把节能降耗作为发展战略的重要内容,提出了降低能耗10-20%的计划目标。目前,从世界炼油化工节能降耗的路径看,关键是工艺技术的突破与创新。纵览世界各国炼油化工节能降耗技术的应用发展趋势,大体包含以下几个方面。联合装置及集成设计主要通过装置大型化及联合装置、炼化一体化、装置热联合和多套装置集成设计等途径实现节能。有关数据表明,在炼油厂规模相同的情况下,采用联合装置可减少设
Refining and chemical industry is a high-energy and high-pollution industry, plays an irreplaceable role in reducing energy consumption, protecting the environment and achieving energy-saving emission reduction targets. In recent years, many large oil and petrochemical companies in the world have put forward plans to reduce energy consumption by 10-20% in order to improve their overall competitiveness and make energy saving and consumption reduction an important part of their development strategies. At present, judging from the path of energy saving and consumption reduction in the world’s refining and chemical industry, the key is the breakthrough and innovation in process technology. Overview of the world’s refining and chemical energy-saving technology application development trend, generally includes the following aspects. Combined devices and integrated design Mainly through large-scale devices and integrated devices, integration of refining and petrochemicals, thermal integration devices and integrated design of multiple devices and other means to achieve energy savings. The data show that in the case of the same size refinery, the use of joint devices can reduce the set
