Abstract

At oil refineries, furnaces account for much of the energy expenditure. Energy efficiency may be improved by means of an integrated system that contains a furnace and a unit for heating the incoming gas with energy recovered from the smokestack gases. By exergetic analysis and efficiency assessment of the energy distribution in the system (on the basis of the zeroth law of thermodynamics), a multifunctional approach to effective integration of the furnace subsystem and the energy subsystem is proposed. That results in greater stability of the integrated system; provides the energy required for all the technological operations, as well as additional inexpensive electrical power; and helps curb thermal pollution of the environment. This approach may be adopted in modernizing existing systems or creating new systems.

炼油厂的炉系统现代化以实现多功能

摘要

在炼油厂，熔炉占能源消耗的大部分。可以通过一个集成系统来提高能源效率，该集成系统包含一个炉子和一个单元，用于利用从烟囱气体中回收的能量来加热进入的气体。通过对系统中能量分布的充分分析和效率评估（基于热力学的零定律），提出了一种有效整合炉子系统和能量子系统的多功能方法。这样可以提高集成系统的稳定性；提供所有技术操作所需的能量，以及额外的廉价电力；并有助于遏制环境的热污染。在使现有系统现代化或创建新系统时可以采用这种方法。
