What standards should be followed for the layout of pilot-scale plants?

The layout of the pilot plant should be designed and implemented in accordance with **relevant safety production standards and fire protection regulations. For pilot-scale plants that use Class A and B flammable media, special attention must be paid to fire safety. The following standards can be referred to: 1. \"Code for Fire Protection Planning in Industrial Enterprises\" (GB 50016-2014), whose Chapter 5 deals with fire protection planning for buildings and equipment, including fire separation measures as well as the selection and placement of fire-fighting equipment. 2. \"Technical Specifications for Occupational Health and Safety in Chemical Manufacturing Enterprises\" (GBZ 2.2-2007), Article 19 requires that storage and use areas for hazardous chemicals be designated as fire prevention zones, and that specialized fire-fighting equipment and emergency facilities be installed. 3. \"Administrative Measures for the Identification of Major Hazard Sources of Hazardous Chemicals and Their Safety Assessment\" (AQ/T 1058-2008), Chapter 7 of which specifies fire protection measures for major hazard sources, including fire isolation, fire-retardant coatings, explosion-proof equipment, etc. Furthermore, the design and implementation of pilot-scale plants also require consideration of the actual conditions on site, with continuous summarization and improvement based on practical experience. At the same time, it is also necessary to strengthen on-site safety management to ensure the safety of personnel and equipment. .

The area is quite small; the distance does not meet the requirements specified in petrochemical or fine chemical standards

Is there a regulation that explicitly states that?

According to the relevant distances stipulated in the Regulations on Environmental Protection Management for Construction Projects, there are no specific requirements set forth regarding the distance between pilot plants and local areas. Relevant standards commonly used in fields such as petrochemicals and fine chemicals include the \"Guidelines for Occupational Health Assessment in Petrochemical Enterprises\" (GBZ/T 117-2004) and the \"Code for Petrochemical Design\" (GB 50041-2018), among others; these standards also do not specify clear requirements regarding the distance between pilot plants and local areas. Therefore, when selecting the location for the pilot plant, it is necessary to take various factors into consideration, such as the surrounding environment, safety measures, and emergency response plans, to ensure that the pilot plant does not cause harm to the surrounding environment or personnel during operation. For certain special occasions or needs, relevant approvals and evaluations can also be carried out to determine the most suitable layout plan. .

Since there is no yet mature process for pilot-scale plants, there are not many clear regulatory requirements; tests are usually carried out in remote areas or certain sections of the plant. Of course, larger-scale pilot plants need to be designed in accordance with the standards applicable to regular chemical projects.

Pilot plants should be classified according to scale.

What is the standard for determining the scale classification?

“The term “scale” does not apply to pilot plants; what amount do you consider to be scale? A few kilograms, a few tons, a thousand tons, or tens of thousands of tons? Sometimes a pilot plant is used to verify a process flow or a test result, so it cannot be measured in terms of “scale”.
