Calculation Method of Energy Saving in Process Engineering: A Case Study of Iron and Steel Production Process

Abstract

The effect of the traditional energy saving mode on process engineering is decreasing, so the idea of system energy saving is developing vigorously. This paper summarizes the existing studies on energy saving from three aspects—energy saving technology, energy management, comprehensive evaluation or analysis—and clearly finds that related studies on energy saving have been gradually promoted to promote the development of system energy saving in the whole process engineering process. Among them, the calculation of energy saving brought by energy saving technology is a difficult point in the research. This paper proposes a novel calculation method of energy saving by taking the iron and steel production process (ISPP) as an example. According to the actual data provided by a steel plant in China, the calculation method is validated effectively.

Application of Comprehensive Energy System in Value Evaluation of Iron and Steel Enterprises

“…Select the following three scenarios to verify the rationality and superiority of the evaluation method. Scenario 1: During the intensive production period of user products, the assembly line starts 24 hours a day, and the load demand is mainly for a large amount of electricity and varying degrees of heat, with electricity/heat synchronization [8]. Scenario 2: During the transition period of user product production, the assembly line starts during working hours (08:00-17:00), and the load demand mainly includes less electricity and specific temperature heat, and the electricity/heat demand is not fully synchronized.…”

Study on Adaptive Parameter Internal Mode Control Method for Argon–Oxygen Refining Ferrochrome Alloy

“…The oxygen blown into the AOD converter is not directly dissolved in the ferrochrome alloy. The CO produced will be changed to CO 2 and discharged [31].…”
