NFPA 36: STANDARD FOR SOLVENT EXTRACTION PLANTS
NFPA 36: 溶剂萃取厂标准
 
1.1 Scope. .
1.1.1* This standard shall apply to the commercial scale extraction processing of animal and vegetable oils and fats by the use of Class I flammable hydrocarbon liquids, hereinafter referred to as “solvents.”
A.1.1.1 Extraction processes that use flammable liquids but are not within the scope of NFPA 36 might be within the scope of NFPA 30, Flammable and Combustible Liquids Code, and the user is referred to that document for guidance. (See Chapter 3 for definitions of terms, including “extraction process” and “solvent.”)
1.1.2 This standard shall also apply to any equipment and buildings that are located within 30 m (100 ft) of the extraction process.
1.1.3 This standard shall also apply to the unloading, storage, and handling of solvents, regardless of distance from the extraction process.
1.1.4 This standard shall also apply to the means by which material to be extracted is conveyed from the preparation process to the extraction process.
1.1.5 This standard shall also apply to the means by which extracted desolventized solids and oils are conveyed from the extraction process.
1.1.6 This standard shall also apply to preparation and meal finishing processes that are connected by conveyor to the extraction process, regardless of intervening distance.
1.1.7* This standard shall not apply to the storage of raw materials or finished products.
A.1.1.7 See NFPA 61, Standard for the Prevention of Fires and Dust Explosions in Agricultural and Food Processing Facilities.
1.1.8 This standard shall not apply to extraction processes that use liquids that are miscible with water.
1.1.9 This standard shall not apply to extraction processes that use flammable gases, liquefied petroleum gases, or nonflammable gases.
1.1.10 This standard shall prohibit the use of processes that employ oxygen-active compounds that are heat or shock sensitive, such as certain organic peroxides, within the area defined in 1.1.2.
 
Maximize fire safety at extraction plants with the 2009 NFPA 36!
Trust NFPA 36: Standard for Solvent Extraction Plants, to mitigate the specialized hazards involved in extraction of oils from agricultural commodities, such as oil-bearing seeds, using hydrocarbon solvents.
Make sure you're working with the latest rules involving:
·   Operations involved in preparing raw material (meal) for processing
·   Storage and handling of the solvent
·   Fire-safe design of the extraction facility and the process equipment
·   Means for conveying the oil and processed solids from the extraction facility
·   Conducting repairs when extraction equipment is operating and when it is shut down and purged of hydrocarbon vapors
Changes incorporated into the 2009 edition of NFPA 36 include:
·   A provision to allow electric space heaters that are approved for Class I, Division 1, Group D and Class II, Division 1, Group G locations to be used in meal preparation areas and in extraction process areas
·   Major revision to the drainage and spill control requirements in Chapter 7, particularly details of the oil/water separation sump
·   Revisions to process control systems
·   Adoption of several new and revised definitions
Order the 2009 NFPA 36 today and minimize risks associated with working in dust-laden or flammable vapor-laden atmospheres. (Softbound, 28 pp., 2009)
