Core Insights - The chemical industry must prioritize energy-saving actions as essential for survival and development, rather than viewing them as additional compliance tasks in the context of achieving dual goals of carbon neutrality and cost reduction [1][3]. Group 1: Cost Reduction and Efficiency Improvement - Chemical companies should focus on "cost reduction" through process optimization to eliminate redundancies and activate resource value, while simultaneously investing saved funds into high-value areas to achieve a dual transformation of "reducing redundancy" and "increasing efficiency" [1]. - For instance, Yangzi Petrochemical implements a "demand-driven" plan declaration management in material supply, ensuring timely delivery and usage of materials, thus avoiding inventory backlog and long turnaround times [1]. Group 2: Energy Consumption Reduction and Innovation - Reducing energy consumption is crucial for cost reduction, but it should not compromise production efficiency; instead, it should be supported by technological innovations that enhance energy utilization efficiency [2]. - Yangzi Petrochemical has focused on reducing oxygen content in heating furnace flue gas by over 0.5% through new technology, which has improved thermal efficiency to 94% and saved over 10,000 tons of fuel gas annually, achieving both energy savings and increased effectiveness [2]. Group 3: Emission Reduction and Value Addition - In the face of stricter environmental regulations, emission reduction is no longer just a compliance cost; it can also extend the industrial chain by transforming waste into valuable resources [2]. - Yangzi Petrochemical has invested in 69 environmental projects over the past three years, reducing total emissions by over 50% through proactive measures and establishing a wastewater reuse system that recycles over 20 million tons of water annually, cutting fresh water intake by 50% [2]. Group 4: Sustainable Development Strategy - The key to energy-saving and cost-reduction in the chemical industry lies in understanding the dialectical relationship between "addition" and "subtraction," where "subtraction" eliminates waste and burdens, creating space for development, while "addition" brings innovation and value, driving growth [3].
