Rewrite the original driving plan for the position – large rewards available

Which process do you use? I have this solution, but it’s for a K-type 1500T/D unit; I’m not sure if it’s what you need.

Cleaning and purging plan for the conversion system: 1. For the first and second conversion furnaces, open their manholes and material access holes to ensure adequate ventilation; personnel enter the furnaces through these manholes to remove debris inside them. 2. Humidifier: Open the access panel and enter to clean out debris inside. 3. Purification furnace: Open the manhole and material feeding hole to ensure adequate ventilation; a person enters the furnace through the manhole to remove debris from inside it. 4. Oil remover: Open the manhole and enter to clean out debris inside. 5. After the aforementioned work and individual unit tests are completed, use the air supplied from the second stage of the compressor to purge each section one by one; when purging, open all drain valves to ensure unobstructed flow. 6. After the purging is complete, check that all oil drainage, waste drainage, pressure gauges, and sampling points are not blocked and remain unobstructed.

Original driving plan for position change I. Preparation work 1. In accordance with the installation and process construction drawings, conduct a thorough and detailed inspection to ensure that all valves, blind flanges, manholes, analysis sampling points, instruments, safety devices, and electrical components are in the correct positions. Whether the quality meets the specified requirements. Whether each analysis solution and analysis instrument can be started properly. Is the supply of water, electricity, steam, etc. normal, and can all upstream and downstream processes operate properly? Have each individual unit, machine, and electrical device undergone individual trial runs? 2. Thorough cleaning: During installation, residues such as welding slag, iron filings, and dust may remain inside the equipment and pipes. If these are not removed, they will block the equipment, pipes, and valves once operation begins, affecting production and safety. Therefore, it is necessary to blow away these debris before driving to ensure smooth driving and prevent accidents. Blowing out is to be carried out using compressed air at a pressure of 0.1–0.2 Mpa, in order to remove debris from the equipment and pipelines along the flow path; when performing this process, the equipment should be handled separately. And strike the pipes and welds hard with a wooden hammer. During purging, the drain valves, pressure gauge pipelines, sampling pipelines, etc. are also purged to ensure unobstructed flow. After cleaning, the valves and flanges should be quickly connected to prepare for the airtightness test. 3. Airtightness test: Adjust the conversion valve, and have the compressor supply compressed air to the conversion unit; once the pressure reaches 0.5 MPa, check for leaks. Pay special attention to checking equipment, manholes, flanges, pipe ends, welds, and instrument connections; if any issues are found, stop the machine immediately and relieve pressure. After processing is complete, send compressed air again. Raise the pressure to 0.8 Mpa; it is considered qualified if no leaks are detected. 4. System purging: After the inert gas in the main gas pipeline meets the requirements, the compressor is started to purge the shift and pressure swing adsorption carbon removal units with inert gas. First, adjust all the valves properly, then contact the compressor to supply gas; proceed along the process flow to perform displacement for conversion and decarburization, with the gas being released from port 70. The sample analysis shows that an oxygen content of less than 0.5% in the gas is considered acceptable. 5. Catalyst heating and reduction plan: Develop a scientific and reasonable plan for the heating and reduction of the catalyst, draw the corresponding heating and reduction curve, and prepare items such as record sheets, flow meters, and U-tube manometers. Check that the electric furnace, electrical appliances, and instruments are functioning properly before proceeding. Skilled and responsible operators are assigned to carry out the operations strictly in accordance with the heating and reduction plan, to ensure its smooth execution. II. Steps for starting the machine 1. Inspection Before operation, for safety reasons, check again whether all equipment, pipes, valves, safety devices, as well as electrical components and instruments meet the requirements for starting the machine. 2. Perform system replacement again to ensure that the oxygen content in the cooling tower’s exhaust air is less than 0.5%; after the replacement is successful, conduct pressure testing and leak checks once more. 3. Check whether the pressures of steam, soft water, and cooling water are sufficient. 4. Are the gas masks and fire-fighting equipment complete and in good condition? 5. Steps for starting up the equipment: 5.1 Contact the teams responsible for decarburization, desulfurization, compressors, etc. to ensure that all preparations are in place. 5.2 Connect to the boiler to supply steam. 5.3 Roots blower. 5.4 Use a Roots blower to cyclically raise the temperature according to the temperature-raising and reduction scheme. 5.5 Contact the compressor to supply air according to the temperature rise requirement. 5.6 Use a cold chamber and an electric furnace to control the heating rate according to the required temperature rise. 5.7 Adjust the amount of quench water and steam according to the transformation temperature. 5.7 After the temperature-raising reduction is complete, gradually increase the load and lower the furnace voltage. Until the electric furnace was removed, the carbon monoxide and sulfur contents at the analysis conversion outlet were measured. It is possible to determine the reduction status of the catalyst.

Inform the on-site personnel to confirm the nitrogen circulation process. Confirm that SP-4 is closed and set to the “local” position. Confirm that SP-104 is closed and set to the “local” position. Open the exhaust valve at 104-DB to relieve pressure. Confirm that the pressure gauge PI-66 at 104-DB indicates 0 Mpa. Close the exhaust valve at 104-DB. Open the bypass valve of PIC-3 to completely relieve the pressure in F66401. Report to the shift leader that the pressures in 104-DB and F66401 have been relieved. Contact the relevant personnel to switch the blind flanges on N-15-18” and N-20-18” to the “open” position. Confirm that the “8”-shaped blind flanges at the inlet and outlet of the nitrogen circulation system in 104-DB are in the correct position. Open the two nitrogen circulation valves on N-15-18” and N-20-18”. Open the main inlet valve of C66403. Close the bypass valve of C66403. Open the front valve of PCV-3 and close the bypass valve. Open 40% of the inlet valve of J66402. Open 50% of the outlet valve of J66402. Close the bottom drain valve of F66401. Confirm that the CW system in C66404 is operational. Confirm that the purity of N2 at C66403 is greater than 99.9%. Open the N2 supply valve at C66403 to increase the pressure there. Start the PCV-3 system for purging. Confirm that the N2 purification in the low-pressure conversion system is complete (O2 level)

1. Driving operations (1) Initial driving: The steps for initial driving are as follows. ①Preparations before driving. After the equipment is installed, it is inspected, cleaned, purged, subjected to a gas-tightness test, catalyst is loaded, and the system is purged in accordance with the specified procedures and methods. ②Catalyst heating sulfidation: A suitable heating sulfidation plan is developed based on the properties of different catalyst models. Depending on the specific conditions of the factory, either the one-pass gas method or the gas circulation sulfidation method can be used for sulfidation. The B303Q catalyst is sulfided using a one-pass gas method, and the control parameters for sulfiding at elevated temperatures are shown in Table 3-14. Table 3-14 Control parameters for the sulfidation of the BQ303Q catalyst Phase Time/h Space velocity/h-1 Bed temperature/℃ H2S content entering the reactor (g/m3) Remarks Heating phase: 8–02, 00160–180 – Displacement first, then heating Initial sulfidation phase: 10–12, 200, 200–300, 10–20; if outlet H2S > 3 g/m3, penetration has occurred Intensification phase: 8–10, 200, 300–350, 10–20; if outlet H2S > 10 g/m3 or CS2 contents at inlet and outlet are similar 8–10, 200, 350–430, 20–40 Cooling and displacement phase: 4–8, 200 – If outlet H2S is 3 g/m3 (standard), it indicates that the catalyst has been penetrated, and the intensification phase can begin. During the strengthening phase, the outlet temperature of the electric furnace is gradually increased to 300–350°C and maintained for 8 hours. Afterwards, both the outlet temperature of the electric furnace and the amount of CS2 added are increased step by step to raise the catalyst temperature to 350–430°C, with this temperature being maintained for 8 hours. When the temperature at all points in the bed reaches 425°C and is maintained for more than 4 hours, and when the H2S content in the exhaust gas remains above 10 g/m3 (standard) for three consecutive times, it can be considered that the sulfidation process is complete. After sulfidation is complete, gradually increase the circulation rate of semi-water gas to lower the temperature, and increase the amount of gas vented for sulfur removal (if sulfidation is carried out on semi-water gas that has already been desulfurized, it is necessary to continue adding CS2 at temperatures above 300°C to prevent the already sulfidized catalyst from undergoing desulfidation). Once the temperature drops below 300°C, analyze the H2S content at the outlet

There are quite a few transformations available. Thank you for your contribution; I’ve learned from it.
