Energy consumption analysis of products is of great significance for evaluating the sustainability of processes in chemical processing systems.A reasonable evaluation of energy consumption for streams in the system is crucial to ensure the accuracy and rationality of energy allocation to products.From the view of energy consumption assessment of waste streams
a reasonable analysis of streams is examined by distinguishing the types of energy consumption and their allocating coefficients.A device-level MFA-EFA energy consumption assessment approach of the product is proposed based on mass flow analysis (MFA) and exergy flow analysis (EFA).The proposed method is used to evaluate energy consumption of five products in the vacuum gas oil hydrotreating unit in a refinery.The consistency of the proposed method is exemplified from three aspects including devise or process scales
energy consumption intensity and CO2 emission intensity of the products.
