Abstract: In the context of the “Dual Carbon” strategy, green and low-carbon transition constitutes the inevitable pathway for refining and chemical enterprises to overcome development bottlenecks and enhance their overall competitiveness. Drawing on field research and engineering practice and taking Enterprise E (a refining and chemical enterprise) as the research subject, this paper systematically reviews and elaborates the core practical pathways of its green transition, covering four key dimensions: production-side transformation, product-side upgrading, energy and resource synergy, and the construction of safeguard systems. The actual implementation of Enterprise E’s green transition engineering strategy has demonstrated significant reduction in the enterprise’s comprehensive energy consumption, total carbon emissions, and pollutant emission levels, achieving industry-leading standards. This study translates the green transformation imperatives of the refining and chemical industry into concrete and actionable practical solutions. It provides guidance and reference for the refinement and implementation of green transition engineering strategies in refining and chemical enterprises, and offers valuable insights for the transition of similar enterprises.
