Norm of energy consumption per unit production of
dimethyl siloxane
1 Scope
This document specifies the grade, technical requirements, statistical scope and
calculation method of the allowance of comprehensive energy consumption per unit
production (referred to as energy consumption) of dimethyl siloxane.
This document is applicable to the calculation and assessment of the comprehensive
energy consumption per unit production of dimethyl siloxane, as well as the energy
consumption control of new (renovation, expansion) projects.
2 Normative references
The provisions of the following documents constitute the essential clauses of this
document through normative references in this text. Among them, for referenced
documents with dates, only the versions corresponding to the dates are applicable to
this document; for referenced documents without dates, the latest versions (including
all amendments) are applicable to this document.
GB/T 2589 General rules for calculation of the comprehensive energy consumption
GB/T 12723 General principles for establishing allowance of energy consumption
per unit throughput
GB/T 20436 Dimethylsiloxane cyclics mixture
GB/T 23953 Dimethyldichlorosilane for industrial use
3 Terms and definitions
The terms and definitions defined in GB/T 12723 and the following apply to this
document.
3.1 hydrolysate
A mixture with the main components of hydroxy-terminated polydimethylsiloxane and
cyclosiloxane.
5 Technical requirements
5.1 Limit value of comprehensive energy consumption per unit production of
dimethyl siloxane
The limit value of comprehensive energy consumption per unit product of existing
dimethyl siloxane production enterprises shall comply with Grade 3 in Table 1.
5.2 Access value of comprehensive energy consumption per unit production of
dimethyl siloxane
The access value of comprehensive energy consumption per unit product of new
(expanded, renovated) dimethyl siloxane production enterprises shall comply with
Grade 2 in Table 1.
6 Statistical scope and calculation method
6.1 Statistical scope of comprehensive energy consumption of dimethyl siloxane
6.1.1 The comprehensive energy consumption of dimethyl siloxane mainly includes the
energy consumption of the production system, the energy consumption of the auxiliary
production system and the energy consumption of the ancillary production system.
6.1.2 The energy consumption of the production system refers to the total amount of
various energy actually consumed by the complete process including the silicon powder
processing, monochloromethane synthesis, organosilicon monomer synthesis,
organosilicon monomer distillation, organosilicon high-boiling cracking, the
comprehensive utilization of dimethyldichlorosilane, dimethyldichlorosilane
hydrolysis, dimethyl siloxane refining, cracking, dimethyl cyclosiloxane distillation,
storage of finished dimethyl siloxane, and pre-treatment and discharge of waste liquid,
waste residue and waste gas, as well as energy consumption by equipment.
6.1.3 The energy consumption of auxiliary production systems refers to the total amount
of energy consumed by the processes, facilities and equipment of the production system
services, including the total amount of energy consumed by the power supply, water
supply, gas supply, heating, refrigeration, machine repair, instrument repair, lighting,
warehouses and raw material sites within the factory, as well as safety and
environmental protection facilities.
6.1.4 The energy consumption of ancillary production systems refers to the total amount
of energy consumed by departments and units that provide services for production
during the production process, including the total amount of energy consumed by
facilities such as offices, operation rooms, lounges, changing rooms, bathhouses,
central control analysis, finished product inspection and maintenance.
6.1.5 The comprehensive energy consumption of dimethyl siloxane does not include
the energy consumed in the construction of infrastructure, technological transformation
and other projects, as well as the energy recycled and exported during the production
process.
6.2 Calculation method
6.2.1 General
The actual consumption of various fuel energies shall be converted into standard coal
according to its lower heating value as received in accordance with GB/T 2589.The
lower heating value of energy and the energy consumption of the energy-consumed
medium shall be converted into standard coal according to the measured values or the
data provided by the supply unit. If the measured values cannot be obtained, the
conversion coefficient can be referred to in Appendix A and Appendix B.
6.2.2 Calculation of comprehensive energy consumption of dimethyl siloxane
products
The energy consumption of dimethyl siloxane shall be calculated based on the actual
measured value. The measurement readings of steam and other energy and energy-
consumed medium entering the production process shall prevail.
When an enterprise purchases silicon powder and methyl chloride as raw materials for
the production of organic silicon monomers, the energy consumption of the purchased
raw materials is calculated by multiplying the unit energy consumption of the
enterprise's current production of silicon powder and methyl chloride by the purchased
volume and included in the total energy consumption. If there are no actual energy
consumption monitoring conditions, the unit energy consumption of purchased methyl
chloride is converted with reference to the conversion coefficient of 0.0797 tce/t, and
the unit energy consumption of purchased silicon powder is converted with reference
to the conversion coefficient of 0.0275 tce/t.
The comprehensive energy consumption of dimethyl siloxane products is calculated
according to formula (1).
where.
E -- the comprehensive energy consumption of dimethyl siloxane products during
the reporting period, in kilograms of standard coal (kgce);
ci -- the physical quantity of the i-th energy consumed by the dimethyl siloxane
