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.
