The norm of energy consumption per unit product of ethylene plant 1 Scope This Standard specifies the technical requirements, statistical range, calculation method, energy-saving management and measures of the norm of energy consumption per unit of product of ethylene plant. This Standard applies to the calculation and evaluation of the energy consumption for the ethylene plant that uses petroleum hydrocarbons as the materials for producing ethylene, propylene, mixed C4, pyrolysis gasoline, hydrogen, and other products after being processed by steam pyrolysis, quenching, compression and separation, and the energy consumption control of new projects. 2 Normative references The following documents are essential for the application of this document. For dated references, only the versions with the dates indicated are applicable to this document. For undated references, only the latest versions (including all the amendments) are applicable to this document. GB 17167 General principle for equipping and managing of the measuring instrument of energy in organization of energy using GB/T 12723 General principles for establishing allowance of energy consumption per unit throughput GB/T 23331 Energy management systems - Requirements 3 Terms and definitions The following terms and definitions defined according to the GB/T 12723 are applicable to this document. 3.1 Energy consumption for ethylene plant It refers to the sum of the physical quantity of various fuels, steam, electricity and energy-consuming working medium actually consumed in the manufacturing process of ethylene plant, within the statistical reporting period, 4.3 Advanced value of energy consumption per unit product of ethylene plant The advanced value of energy consumption per unit product of ethylene plant shall meet the requirements for the advanced value of energy consumption for unit output of ethylene or energy consumption for unit output of ethylene and propylene, specified in Table 3. Table 3 Advanced value of energy consumption per unit product of ethylene plant Type Advanced Value of Energy Consumption for Unit Output of Ethylene Advanced Value of Energy Consumption for Unit Output of Ethylene and Propylene Ethylene plant ≤ 610kgoe/t ≤ 400kgoe/t 5 Statistical range and calculation method 5.1 Statistical range The statistical boundary of energy consumption for ethylene plant includes various units, such as the zones for material desulfurization and dearsenication, cracking furnaces, quenching, compression and separation, the flare gas recovery compressor, the storage tanks of ethylene products, etc.; it does not include the gasoline hydrogenation unit, auxiliary boilers, main torch, spent caustic processing unit, storage tanks of other products, circulating water field, air compression station, etc. See Appendix A for the sketch map for the statistical boundary of energy consumption for ethylene plant. 5.2 Statistical requirements 5.2.1 The energy consumption statistics for ethylene plant includes fuels, electricity, steam and energy-consuming working medium. The energy- consuming working medium includes fresh water, circulating water, demineralized water, deoxygenated water, condensation water, nitrogen, and compressed air. 5.2.2 The fuels consumed by ethylene plant refer to the sum of various fuels consumed in the statistical boundary. 5.2.3 The energy consumption includes the energies consumed in the process of manufacturing, plant operation and shutdown, overhaul and maintenance; it does not include the energies consumed for basic infrastructure. 5.2.4 The magnitudes of output energies shall be consistent with those of output and input energies obtained from the statistical calculation. The output energies that have not been consumed yet shall not be used for energy output statistics. Appendix B (Normative) Conversion values of the energy for ethylene plant and the energy- consuming working medium See Table B.1 for the conversion values of the energy for ethylene plant and the energy-consuming working medium.
