GB/T 17145-2024Guidelines for recycling of used mineral oil (English PDF)

1 Scope

GB/T 17145-2024 is the Chinese national standard on guidelines for recycling of used mineral oil, in the field of environment and health protection, safety. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 28 November 2024 by the State Administration for Market Regulation; Standardization Administration of China, and has been in force since 28 November 2024. Classification: ICS 13.030.50, CCS Z04. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This document specifies the general requirements, recycling management requirements, recycling process requirements, environmental protection requirements, and regenerated product management requirements for recycling of used mineral oil. This document applies to recycling of used mineral oils such as waste engine oil, waste hydraulic oil, waste gear oil, waste turbine oil, waste transformer oil, waste anti-rust oil, waste solvent oil, waste cutting oil, and waste heat treatment oil generated in mechanical equipment, power equipment, electrical equipment, metal processing and transportation vehicles (automobiles, trains, ships, aircraft). This document does not apply to mineral oil-containing wastes such as oily sludge and residues generated during the extraction and refining of oil and natural gas, nor does it apply to the energy utilization and disposal of used mineral oil and mineral oil- containing wastes.

4.2 The generating and collecting organizations of used mineral oil are encouraged to use auxiliary information systems to standardize the management of ledgers and transfer forms. The key environmental supervision organizations of hazardous wastes specified in

HJ 1259 shall use electronic floor scales, electronic tags, electronic management ledgers and other technical means to carry out information management of the storage process of used mineral oil.

4.3 When engaging in the collection or utilization of used mineral oil, the occurrence of unexpected accidents such as leakage and fire of used mineral oil shall be prevented, and risks and hidden dangers shall be eliminated in time.

4.4 The utilizing organizations shall have production equipment and technical processes that meet the requirements of industry norms and conditions, and have the equipment and technical capabilities to test the quality of used mineral oil and its regenerated products.

4.5 The utilizing organizations shall have pollutant treatment facilities and safety fire- fighting facilities that meet environmental protection and safety requirements.

6 Recycling process requirements

6.1 Used mineral oil utilizing organizations shall adopt energy-saving, environmentally friendly, safe and mature processes and equipment that meet national and local requirements, and shall not use processes and equipment that have been explicitly eliminated by national or local orders.

6.2 Used mineral oil utilizing organizations shall adopt one of the two combined processes of pretreatment - distillation (evaporation) - solvent refining and pretreatment - distillation (evaporation) - hydrofining. For suitable used mineral oil raw materials, it is allowed to directly adopt the process of hydrogenation first and then distillation without distillation.

6.3 The distillation (evaporation) process shall adopt process technologies that can be operated stably, such as continuously operated atmospheric and vacuum tower distillation, thin film evaporation, molecular distillation, high vacuum cyclone evaporation, cyclone flash evaporation and thin film reboiling.

6.4 It shall not adopt open flame high temperature heating to treat used mineral oil in intermittent kettle distillation (thermal cracking and catalytic cracking) equipment, which will produce regenerated oil products that do not meet national gasoline and diesel product standards.

6.5 The refining process shall adopt solvent refining or hydrofining technology, and it shall not adopt sulfuric acid + clay refining, aluminum chloride (solid acid) + clay refining and other acidic compounds + clay refining processes.

6.6 The regenerated base oil treated by solvent refining or hydrofining process can be appropriately treated with clay supplementary refining to improve the oxidation stability of the product. Except for the use of clay supplementary refining in solvent refining or hydrofining, other forms of clay adsorption refining process, mineral sand adsorption refining process or diatomaceous earth adsorption refining process shall not be used.

6.7 The main solvent of the solvent refining process should be environmentally friendly, cheap and safe, such as N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMAC), N-methylpyrrolidone (NMP), furfural, furfuryl alcohol.

6.8 The equipment, facilities and materials used by the used mineral oil utilizing organizations in the construction of the used mineral oil utilization project shall comply with national and petrochemical related industry standards. The design and construction of the used mineral oil utilization project shall be undertaken by engineering design and construction organizations with petrochemical qualifications.

7 Environmental protection requirements

7.1 Pollution control in the recycling and utilization links of used mineral oil generating organizations, collecting organizations and utilizing organizations shall comply with the provisions of HJ 607 to avoid secondary pollution to the ecological environment. Pollutant discharge permit management shall comply with the relevant provisions of HJ 1034 for used mineral oil processing industry.

7.2 The construction of storage sites shall comply with the relevant provisions of GB 18597; storage sites shall have special signs for solid waste storage (disposal) sites that comply with GB 15562.2 and its amendments; storage containers shall be affixed with hazardous waste labels in accordance with the requirements of GB 18597, and storage sites and storage facilities shall comply with the provisions of HJ 1276.
