Scope

This Document specifies the norm levels, technical requirements, and statistical range of energy
consumption per unit production (abbreviated as energy consumption) of toluene diisocyanate
(TDI) and diphenyl methane diisocyanate (MDI); and describes the calculation method for them.
This Document is applicable to the calculation and assessment of energy consumption per unit
production of TDI produced with dinitrotoluene (DNT), hydrogen, chlorine, and carbon
monoxide as raw materials, and MDI produced with aniline, formaldehyde, chlorine, and
carbon monoxide as raw materials, as well as energy consumption control for new construction
and renovation and expansion projects.
