NFPA NFPA 36 Handbook 2021 Free Download: Solvent Extraction Plants

The NFPA 36 standard provides design, construction, and operational requirements to mitigate fire and explosion hazards in plants involved in the extraction processing of animal and vegetable oils and fats using Class I flammable hydrocarbon liquids. Here are the key points from the 2021 edition of NFPA 36: 1. Scope and Application: - The standard applies to the commercial scale extraction processing of animal and vegetable oils and fats using Class I flammable hydrocarbon liquids (referred to as "solvents"). - It also covers equipment and buildings located within 30 meters (100 feet) of the extraction process. - The standard extends to the unloading, storage, and handling of solvents, regardless of their distance from the extraction process. - It addresses the conveyance of material from the preparation process to the extraction process and the conveyance of extracted desolventized solids and oils. - Preparation and meal finishing processes connected by conveyor to the extraction process are also included, regardless of intervening distance. - However, it does not apply to the storage of raw materials or finished products. - Additionally, it excludes extraction processes using liquids that are miscible with water or flammable gases, liquefied petroleum gases, or nonflammable gases. 2. Safety Measures: - NFPA 36 ensures greater fire safety and minimizes risks at solvent extraction plants. - It specifically addresses the hazards involved in the extraction of oils from agricultural commodities using hydrocarbon solvents. NFPA 36 plays a critical role in safeguarding lives, property, and the environment by promoting safe practices in the extraction industry.
