2 Basic engineering design
2.1 Overview
2.1.1 The engineering design stage is divided into the basic engineering design stage and the detailed engineering design stage. In the engineering design stage, the piping and instrumentation flow diagram (P&ID) should be issued in 7 versions, namely: 1P&IDA version (initial version);
2P&IDB version (internal review version);
3P&IDC version (user version);
4P&IDD version (confirmation version);
5P&IDE version (detailed version 1);
6P&IDF version (detailed version 2);
7P&IDG version (construction version).
The basic engineering design stage is the period of drawing the first 4 versions of P&ID (P&IDA, BC, D), and the detailed engineering design stage is the period of drawing the last 3 versions of P&ID (P&IDE, F, G). For some engineering projects, when P&ID user review is not conducted or the equipment order modification quantity is small, P&ID does not need to draw 7 versions.
2.1.2 Engineering design is carried out on the basis of basic design/preliminary design. The production control scheme and instrument selection have been basically determined in the basic design/preliminary design stage. If the basic design/preliminary design review meeting does not propose any modification opinions on the control scheme and instrument selection, the engineering design can be carried out according to the determined scheme and instrument selection. 2.2 Technical preparation before design start
2.2.1 Collect relevant design technical information, instrument product manuals, samples, etc. according to the production scale, process characteristics, operation requirements, process control scheme and instrument selection of the process unit. 2.2.2 When necessary, conduct research at relevant chemical production plants, research institutes, and manufacturing plants to solve technical problems left over from the basic design/preliminary design. bzxz.net

3.1 Overview
3.1.1 It is a common practice for engineering companies (design departments) to carry out procurement of instrument equipment and installation materials during the engineering design stage when undertaking general contracting projects. Starting from the basic engineering design stage, the procurement department carries out procurement work based on the design documents submitted by the design department. The design department carries out detailed engineering design according to the order situation of the procurement department.
If it is not a general contracting project, the procurement work specified in this chapter will not be arranged when the user is responsible for the procurement work. The procurement work of instruments and installation materials is the responsibility of the procurement department, and the automatic control professional cooperates. The main cooperation work in the engineering design stage is as follows:
Submit technical documents for procurement:
Prepare instrument purchase requisition;
Participate in the technical review of manufacturers' quotations;
Review and confirm Guangshang technical documents.
3.2 Submitting procurement technical documents
3.2.1 Some design documents prepared (drawn) during the basic engineering design phase, such as instrument design regulations, instrument data sheets, instrument panel layout diagrams, DCS system configuration diagrams (preliminary), etc., are the main components of procurement technical documents and should be submitted to the procurement department according to the needs of procurement work. 3.2.2 According to the instrument selection of the project, prepare the technical specifications of the main instruments and the technical specifications of the DCS (including PLC), and submit them to the procurement department. 3.3 Preparation of instrument purchase requisition
3.3.1 After the preparation of instrument procurement technical documents is completed, prepare the instrument purchase requisition according to "Preparation of Instrument Purchase Requisition" (HG/T20637.5).

5OFO.con4 Detailed engineering design
4.1 Overview
4.1.1 Since the preparation of many design documents of the automatic control department can only be carried out after obtaining relevant information from the manufacturer, after the detailed engineering design begins and the instrument procurement work has not yet been completed, the automatic control department can first carry out the preparation of design documents that are not affected by the technical information of the instrument manufacturer. 4.1.2 The detailed engineering design of the automatic control specialty is the continuation and deepening of the basic engineering design. In addition to cooperating with the procurement department to complete the procurement work, there is no strict boundary between the two as far as the automatic control specialty is concerned. 4.2 Submit instrument connection and installation design conditions 4.2.1 The instrument interface size conditions should include the following: 1. Submit the instrument data sheet or "control valve and flow meter data sheet" of the control valve and flow meter with the determined model, specification and size to the system specialty (this sheet is submitted by the system specialty, reviewed by the automatic control specialty, and returned with the determined model and specification). 2. Submit the instrument connection conditions to the pipeline specialty, mainly submitting the connection sizes of control valves and various flow meters. For the source and sampling components or valves of temperature, pressure, flow, analysis and other parameters on the pipeline, the automatic control specialty shall submit the automatic control installation drawing number to the pipeline specialty, and then the pipeline specialty shall design according to the requirements of the automatic control installation drawing. 3. Submit the instrument container connection diagram to the equipment specialty. In addition to the temperature and pressure detection points, the design conditions can be submitted directly to the equipment department. For certain liquid level measurement points that require the installation of source stop valves, the design conditions must be submitted to both the equipment department and the pipeline department, because the stop valve is designed by the pipeline department. 4.2.2 When the sending end of the interlocking system is the process parameter and the execution end is the electrical equipment, the automatic control department shall propose the design conditions for executing the interlocking action to the electrical department. When it is necessary to set up a separate instrument grounding device, the automatic control department shall propose the instrument grounding design conditions, and the electrical department shall be responsible for the design of the grounding device.
4.2.3 Submit the instrument installation conditions to the civil engineering department, including the pre-processing design conditions of the installation brackets such as field instruments, protection (temperature) boxes, cable trays, etc., and the basic design conditions of the control room instrument panel (cabinet) or DCS operating table, cabinets, etc.
Standard submission network cb0.co All kinds of standard industry data are free to download 4.3 Accept pipeline plan and subcontractor technical documents 4.3.1 After the P&IDD version and D version pipeline naming table are published, the pipeline professional will draw the pipeline plan and carry out model design (when necessary). When the design reaches a certain stage, a model review meeting and instrument positioning meeting will be held, at which the location of the source and sampling point of the instrument and analysis will be agreed upon. After receiving the first version of the pipeline plan, the automatic control professional will start to draw the instrument location diagram, instrument cable and bridge layout diagram, on-site instrument wiring diagram, etc.
4.3.2 In general, the subcontractor is only responsible for the design and supply of random instruments and dials, while the installation of the dial and the design and supply of instrument power supply, signal cable and wires are the responsibility of the main design unit. At this time, the subcontractor must provide relevant instrument design information for the main party to draw the instrument cable and bridge layout diagram and count the instrument installation materials. 4.4 Cooperate with the system professional to complete P&ID version, F version, and G version 4.4.1. Cooperate with the system professional to complete the P&IDE version (detailed version 1). The P&IDE version is drawn based on the D version according to the final version of the data provided by the manufacturer, as well as the changes and modification opinions of the pipeline and automatic control professionals, and is used for the detailed version 2 (design version) drawing of the pipeline and equipment layout diagram. 4.4.2. Cooperate with the system professional to complete the P&IDF version (detailed version 2). The P&IDF version is published as needed, that is, it is drawn only when the data of the manufacturers of pipelines, instruments, pumps, etc. are greatly modified. 4.4.3. Cooperate with the system professional to complete the P&IDG version (construction version). The P&IDG version is the final version, which is the basis for construction, installation, preparation of process operation manuals, and start-up, production, and accident handling. 4.5. Complete the engineering design documents
In the basic engineering design stage, although part of the design documents have been compiled (drawn), since the instruments have not yet been ordered, their models and specifications cannot be completely determined, so this part of the documents is only a semi-finished product. In the detailed engineering design stage, as the instrument ordering work is carried out in depth, the compilation (drawing) of the engineering design documents of this major can be carried out in an all-round way. 4.5.1 For projects using conventional instruments, the design documents that need to be completed are as follows: 1 Text and table documents
