GB 21344-2023 Norm of energy consumption per unit production of fertilizer industry

Scope

This document stipulates the energy consumption (hereinafter referred to as "energy consumption") limit levels, technical requirements, energy consumption statistical scope, and calculation methods for synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate, and potassium sulfate. This document applies to the calculation and assessment of energy consumption for production enterprises of synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate, and potassium sulfate, as well as the energy consumption control of new and expanded projects. This document does not apply to the following production enterprises: - Producing synthetic ammonia using heavy oil, residual oil, or coke oven gas as raw materials; - Producing ammonium bicarbonate from by-products such as melamine tail gas; - Producing monoammonium phosphate and diammonium phosphate from industrial-grade monoammonium phosphate and industrial-grade diammonium phosphate; - Producing monoammonium phosphate and diammonium phosphate from commercial phosphoric acid; - Producing potassium sulfate from seawater or brine for potassium sulfate magnesium fertilizer, or using methods such as ammonium sulfate conversion, gypsum conversion, and mixed salt production to produce potassium sulfate.
