Abstract:

“Emission peak and Carbon neutrality target” brings new challenges to chemical production. Improving energy supply structure and enhancing energy efficiency are ones of the important ways to solve this problem. With the continuous development and improvement of energy conversion technology and energy storage technology, the utilization level and supply stability of renewable energy are further improved. It has obvious advantages in replacing chemical utilities system mainly based on fossil energy, and is considered as the most promising way of energy supply for a new generation of chemical systems. Based on the technology of renewable energy supply, this paper summarizes the application status of renewable energy in new chemical utilities such as heating, cooling, water supply, power supply and multigeneration system, and highlights the important role of renewable energy in energy saving and emission reduction compared with traditional chemical utilities. The matching status, problems and challenges of renewable energy in chemical utilities are discussed, and its future development is forecasted. The paper points out that the renewable energy chemical public engineering will become an important way to solve the dilemma of chemical environmental protection.

Key words: renewable energy, chemical utilities, process systems, optimal design, energy saving and emission reduction

摘要:

“双碳目标”对化工生产提出了新的挑战,改善能源供给结构和提升能源利用效率是解决这一问题的重要途径之一。随着能源转换技术和储能技术不断发展和完善,可再生能源利用水平及供应稳定性进一步提高,在替代以化石能源为主的化工公用工程系统方面有着明显的优势,被认为是最具应用前景的新一代化工系统供能方式。本文在可再生能源供能技术的基础上,总结了可再生能源在供热、制冷、供水、供电以及多联产系统等新型化工公用工程中的应用现状,着重突出了可再生能源相比传统化工公用工程在节能减排方面发挥的重要作用。探讨了可再生能源目前在化工公用工程系统中的耦合匹配现状、应用所遇到的问题和挑战,并对其未来发展进行了展望。文章指出,可再生能源化工公用工程将成为解决目前化工环保困境的重要途径。
