\"Fire Protection Standards for the Design of Petrochemical Enterprises\" and Difficulties in Engineering Design

Thread Content

The \"Code for Fire Protection Design of Petrochemical Enterprises\" (abbreviated as the \"Petrochemical Code\") serves as the basis for fire protection design in petrochemical projects, and it is also used by safety and fire protection authorities as a guide for reviewing and supervising such projects. This standard was implemented in July 2009, but it has been continuously revised and improved in light of evolving circumstances. The Ministry of Housing and Urban-Rural Development approved the revised 2018 version of the \"Fire Protection Design Standards for Petrochemical Enterprises\", which came into effect on April 1, 2019. Among them, clauses 4.1.9, 4.2.12, 5.3.4, 5.6.1, 6.2.6 (1, 2, 3, 4), 6.3.2 (1, 2, 4), 6.4.1 (2, 3), 6.4.2 (6), 8.3.8, and 8.7.2 (1, 2) are mandatory provisions that must be strictly enforced. The original text as amended is hereby repealed simultaneously. (1) Main contents of the \"Fire Protection Design Standard for Petrochemical Enterprises\" 1. Relevant aspects of inter-plant pipeline planning and installation ； 2. Fire separation distances for utility facilities in petrochemical enterprises and petrochemical parks ； 3. Layout requirements for facilities within different ranges of radiant heat intensity from elevated torches ； 4. Layout requirements when the area occupied by a set of combined units exceeds 80,000㎡ ； 5. Regulations on the floor area of each urea warehouse and the building area of fire compartments ； 6. Regulations for the installation of fire protection water supply systems when the factory area exceeds 1,000,000㎡ ； The most recent revision added Sections 4.5 and 7.4, as well as 25 items including 2.0.35, 4.1.9, 4.1.11, and 4.1.12 ； A total of 52 clauses, including 4.1.2, 4.1.9, 4.1.10, 4.2.3, 4.2.12, 4.3.4, and 4.4.2, were mainly revised. (II) Flexible application and resolution of difficulties in the implementation of the \"Fire Protection Design Standards for Petrochemical Enterprises\" 1. Fire separation distances for petrochemical enterprises and similar enterprises ； Fire separation distance for inter-plant pipelines and adjacent factories or facilities ； 2. Difficult issues in the storage, transportation, and interplant pipeline sections of the “Petrochemical Regulations” ； 3. Analysis of difficult issues regarding chemical park and plant layout in the “Petrochemical Regulations” ； 4. Issues to be noted by small petrochemical enterprises when implementing the “standards” ； 5. Differences and harmonization issues between the \"Petroleum Chemical Code\" and the \"Construction Code\", as well as certain provisions in codes such as the \"Design Code for Oil Depots\". 6. Difficulties in selecting between “Construction Codes” and “Petroleum and Chemical Industry Codes” in chemical engineering design. For example: \"How to handle situations where the client’s requirements conflict with the standards?\" ”The design is carried out in accordance with the ‘Petroleum and Chemical Industry Regulations’, but during the fire safety review, the authorities conduct the assessment based on the ‘Building Code’. There is a lack of clear guidelines regarding the design criteria.” “When a chemical processing project shares a common wall with other enterprises, and those adjacent enterprises are not of the same type, how should the required clearance distances be determined?” “When non-petroleum and chemical industry facilities are located within a planned chemical industrial park, which regulations should be applied: the ‘Petroleum and Chemical Industry Regulations’ or the ‘Building Code’? ”“‘How should the overlapping blind spots regarding fire separation distances in the ‘Building Code’ and the ‘Petroleum Industry Code’ be addressed? ”Wait. (III) Examples of fire protection design and construction drawing review in petrochemical engineering
1. Fire protection design methods, requirements regarding design depth, and key points for construction drawing review ； 2. Explain the typical layout of a certain engineering project in conjunction with petrochemical regulations. (IV) Fire protection topics 1. Current problems in fire water supply and fire hydrant systems in China, as well as solutions and approaches ； 2. Issues regarding pressure-stabilizing pumps and the installation of high-level fire water tanks under the \"Water Drainage Regulations\" and \"Petroleum and Chemicals Regulations\" ； 3. Design of pump rooms and equipment selection for water supply, fire protection, and other systems ； 4. Fire fighting and rescue in large hazardous chemical areas and foreign fire prevention examples.
