TS 13541

TS 13541 is a general rules standard for waste oil regeneration facilities that continuously process used mineral oils to remove contaminant parameters and produce base oil of suitable quality. It sets out the minimum structural features, operating arrangements, personnel aspects and technical equipment expected for these workplaces, providing a practical framework for orderly regeneration and refining activities with environmental considerations in mind.

Facility types and process logic

The standard refers to vacuum refining and clay-treated plants, vacuum refining and chemical treatment plants, hydrogen-treated vacuum refining plants, thermal cracking plants and other industrial refining plants. These terms describe different re-refining routes used to separate or transform water, solids, additive residues, oxidation products and other unwanted constituents in used oil. In general technical context, the purpose of re-refining is to recover a lubricant-grade base oil stream that can be used again as a raw material for new lubricants or related products.

Occupational safety, environment and management context

• The standard links healthy and safe working principles with environmental principles.
• It focuses on minimum structural and technical characteristics rather than detailed process design.
• Waste oil regeneration is closely connected to waste management, air emissions, water pollution control and permit/licensing frameworks.
• Referenced standards such as TS EN ISO 9001, TS EN ISO 14001 and TS EN ISO/IEC 17025 indicate the broader quality, environmental and testing context around such facilities.

This document was withdrawn in 2016, but it remains a useful technical reference for understanding how waste-oil refining and regeneration facilities are categorized and organized in Turkey.
