GB21344-2023
Norm of energy consumption per unit production of fertilizer industry
化肥行业单位产品能源消耗限额
GB 21344-2023 is a current mandatory Chinese national standard for Norm of energy consumption per unit production of fertilizer industry. It appears in the Construction compliance cluster with a energy efficiency focus and has an implementation date of Dec 1, 2024.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard 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 energy consumption control for new and renovated projects. It does not apply to specific processes such as producing synthetic ammonia using heavy oil or coke oven gas, or producing monoammonium phosphate from industrial-grade materials. This standard integrates and replaces several previous standards, including GB 21344-2015 and GB 29138-2012.
Technical requirements
GB 21344-2023 establishes energy consumption limit grades for six major fertilizer products, categorized into three tiers (with Tier 1 representing the highest energy efficiency). Existing production facilities must comply with the Tier 3 limit values, while new and renovated projects must meet the stricter Tier 2 access values. The standard introduces specific requirements based on different raw material types and driving mechanisms. For instance, it outlines limits for synthetic ammonia based on whether the raw material is premium anthracite lump coal, pulverized coal, lignite, or natural gas. Notably, it adds new requirements for ammonia production using lignite and includes energy consumption adjustment factors for potassium sulfate production during winter in cold regions using the Mannheim process, as well as for granulated products. The statistical scope of energy consumption encompasses the energy consumed by the production system, auxiliary production systems, and affiliated production systems, including energy-consuming working fluids like water and compressed air. It explicitly excludes energy used for construction, renovation, and domestic purposes within the enterprise.
Testing methods
The standard outlines the calculation methods for comprehensive energy consumption and energy consumption per unit of product. Various energy sources must be converted to kilograms of standard coal equivalent (kgce) based on measured calorific values. If actual measurement is not possible, reference coefficients are applied, referencing GB/T 213 and GB/T 11062 for coal and natural gas calorific value determination. The standard also provides specific allocation methods for shared raw material coal, fuel coal, and electricity consumption in enterprises co-producing synthetic ammonia and methanol.
FAQs
What products are regulated under GB 21344-2023?
This standard regulates the energy consumption limits per unit product for synthetic ammonia, urea, ammonium bicarbonate, monoammonium phosphate, diammonium phosphate, and potassium sulfate.
Are there any major updates from the previous versions?
Yes, GB 21344-2023 integrates and replaces six previous standards. Key updates include a modified scope, the addition of energy consumption limits for synthetic ammonia using lignite as a raw material, and specific energy consumption adjustments for potassium sulfate granulation and winter production in cold regions.
What is the difference between requirements for existing and new facilities?
Existing production facilities must comply with the Tier 3 energy consumption limit values, whereas new and renovated/expansion projects must meet the stricter Tier 2 energy consumption access values.
