"Code of Chemical Control Design" is an industry standard organized and compiled by the National Chemical Control Design Technology Center Station according to the basic work tasks for 1999 arranged by the China Chemical Survey and Design Association [19991015]. This regulation contains 13 independent automatic control design regulations such as "Automation Instrument Selection and Design Regulations", which is a standing technical standard for preliminary design/basic design and engineering design (construction drawing design) of chemical control professionals. There are 11 regulations in the "Code of Chemical Control Design" that are revisions to the corresponding regulations of the 1992 edition, 1 regulation (common terms and terms for automatic control design) is a revision of the 1984 edition CD standard, and 1 regulation (programmable controller system setting regulations) is a newly compiled standard. The above-mentioned HG standard of 1992 and CD standard of 1984 have played an important role in the design of chemical automatic control. However, due to the development of instrument manufacturing and automatic control technology, some inapplicable provisions of the 1992 edition need to be revised, and some new contents need to be added; some provisions refer to other professional standards, and the referenced standards have been revised, so the standards of the automatic control profession should also be revised accordingly. The newly compiled 1 regulation was compiled after a long period of preparation based on the needs of automatic control design work. During the revision process, we conducted extensive investigations and studies on the problems existing in the original regulations, summarized the practical experience of chemical automatic control design in recent years, and solicited opinions on design, construction, production, manufacturing, etc. The main issues were discussed many times and finally finalized after review. The Chemical Industry Automatic Control Design Regulations make clear, systematic and detailed regulations for the chemical industry automatic control design work, such as instrument (including PLC) selection, control room (including automatic analyzer room) design, instrument power supply and gas supply and piping and wiring design, signal alarm safety interlock system design, and instrument grounding, heating, insulation, isolation, European washing design and other specific work. In addition, this standard also makes unified regulations for the functional signs and graphic symbols of process measurement and control instruments and common terms and terms for automatic control design. This series of regulations reflects the rich experience of automatic control design work in the chemical industry, adapts to the needs of the development of process control technology at home and abroad, and is in line with relevant international standards. This standard plays a guiding and normative role in the design of chemical industry automatic control, and plays a guarantee role in improving efficiency and design quality. The Chemical Automation Design Regulations and Chemical Plant Automation Engineering Design Regulations (HG/T20636~20639) form a complete set of chemical automation design standards. This standard series includes all the standards required for chemical automation design, such as design management, design document preparation, and various technical regulations for automation design, etc., which meet the needs of various chemical plant automation engineering designs at home and abroad. This regulation is also applicable to automation design work in industries such as petrochemicals, light industry, textiles, medicine, metallurgy, and electricity. Thirteen chemical automatic control design regulations are as follows: 1.
Functional signs and graphic symbols of process measurement and control instrumentsAutomation instrument selection and design regulations
Control room design regulations

This regulation applies to the design of central control room of chemical production equipment, and the design of auxiliary control room and field control room can be implemented as a reference.
1.0.2 The standards cited in this regulation are:
GB 50058
GB 50160
HG/T20512
HG20556
Design Code for Electrical Installations in Explosive and Fire Hazardous Environments, Design Code for Fire Protection in Petrochemical Enterprises,
Design Code for Instrument Piping and Wiring,
Architectural Design Code for Control Rooms in Chemical Plants. When implementing this regulation, the relevant national standards in force shall also be met. 133
2 Central Control Room of Distributed Control System
2.1 Selection of Location of General Plan
2.1.1 The location of the central control room shall be selected in an area without explosion and fire hazard, and its location shall comply with the provisions of the Design Code for Fire Protection in Petrochemical Enterprises (GB50160). If the above provisions cannot be met due to conditions, effective protective measures shall be taken.
2.1.2 A joint control room shall be built for a combined device or multiple process devices in the same boundary area. For factories with conditions, one central control room shall be set up for the whole plant.
2.1.3 For high-voltage and explosion-hazardous process devices, the central control room building shall face away from the device and shall have a certain ability to resist external explosions. 2.1.4 The central control room should be set up separately. When forming a comprehensive building, the central control room should be located on the first floor and should be a relatively independent unit with no direct passages between other units. The control room should not be adjacent to the high-voltage distribution room. If it is adjacent to the high-voltage distribution room, shielding measures should be taken. 2.1.5 In certain circumstances, when the central control room is located in a hazardous area and contains general-purpose electrical equipment or other potential ignition sources, it should prevent the entry of flammable vapors, gases or dust. A positive pressure ventilation system for clean air can be used, and the indoor pressure should not be lower than 25Pa.
2.1.6 The central control room of the whole plant or joint device should be as close to the main device as possible, and the field control case and field cabinet room should be close to the area with frequent operation and concentrated control measurement points. 2.1.7 For process equipment with flammable, explosive, toxic, dusty, water mist or corrosive media, the central control room should be arranged on the upwind side of the dominant wind direction in the region throughout the year or on the leeward side of the wind direction with the lowest frequency throughout the year. 2.1.8 The orientation of the central control room where windows are allowed should be north-facing and south-facing, preferably north-facing or east-facing, and not west-facing. If it cannot be avoided, sunshade measures should be taken.
2.1.9 The central control room should not be close to the main traffic artery of the factory area. If it is unavoidable, the distance between the outermost axis of the control room and the center of the main road should not be less than 20m.
2.1.10 The central control room should be away from high noise sources. 2.1.11 The central control room should be away from vibration sources and places with large electromagnetic interference. For specific regulations, see Articles 2.3.3 and 2.3.5.
2.1.12 The central control room should not be located adjacent to the compressor room and chemical warehouse. 134
