Approval department: State Bureau of Petroleum and Chemical Industry Implementation date: June 1, 2001 National Chemical Engineering Construction Standard Editing Center (formerly the Engineering Construction Standard Editing Center of the Ministry of Chemical Industry) 2001 Beijing
The "Regulations on the Depth of Contents of Preliminary Design of Chemical Plants" promulgated by the Ministry of Chemical Industry in 1988 has been in existence for more than ten years, and some of its contents are no longer suitable for the development of current technology. For this reason, the China Chemical Engineering Survey and Design Association proposed to revise this regulation. The revised regulations were renamed "Regulations on the Depth of Contents of Preliminary Design Documents of Chemical Plants" (HG/T20688-2000), which includes the content depth requirements for the preliminary design of the device.
This regulation is formulated and revised in accordance with the engineering construction industry standards of the State Bureau of Petroleum and Chemical Industry, and is based on the 1988 Ministry of Chemical Industry's regulations. Based on the "Regulations on the Depth of Preliminary Design Contents of Chemical Plants" promulgated in 2000, it was jointly compiled by the China Chemical Engineering Survey and Design Association and the Shandong Provincial Chemical Engineering Planning and Design Institute, and was revised and completed after extensively soliciting opinions from 13 former subordinate and provincial design units. This regulation is a recommended standard.
This regulation applies to the preparation of preliminary design documents for newly built, expanded and rebuilt chemical plants and petrochemical plants. This regulation does not serve as the basis for the division of professional work within the design unit and the order of arrangement of preliminary design documents. In this regulation, the content of equipment layout and piping design is extracted into an independent chapter, and the equipment layout and piping design of chemical plants, auxiliary plants, and public engineering plants can all be followed. According to the different situations of each design unit and the division of professional design, the design content of equipment layout and piping of chemical plants, auxiliary plants, and public engineering plants can be concentrated in the "Layout and Piping" chapter, or placed in the relevant chapters separately, but the depth of their content can all comply with the provisions of this article. The design of other facilities not listed in this regulation can be implemented in accordance with the provisions of the relevant chapters. This regulation does not specify the format of drawings and tables, and each unit can compile according to the regulations of its own unit. This regulation is a general regulation on the content that the preliminary design documents of chemical plants and petrochemical plants should have. With the deepening of the reform of the national construction system, the content of the preliminary design documents should also vary depending on the specific circumstances of the project, the requirements of the project contract and the purpose of the preliminary design documents. Therefore, in specific engineering projects, it is allowed to make corresponding additions and subtractions with reference to the overall requirements of this regulation. Among them, when it is used for government department review or when the preliminary design documents need to be simplified, the content that can be omitted is recommended and has been explained in the relevant chapters of this regulation.
When it is inconvenient to disclose the content that needs to be kept confidential, such as patent technology, in the preliminary design documents, it can be explained in the relevant chapters.
