[Q&A Question 226] 2016.12.02

Inspection of moving equipment, combustion condition of the furnace, detection alarms, leaks in pipelines

Shift handovers must adhere to the \"Ten Deliveries\" and \"Five Non-Acceptances\" principles: \"Ten Deliveries\": deliver tasks and instructions, operational procedures, performance targets, quality standards, equipment, safety measures, environmental and hygiene requirements, experience, tools, and records； “The \"Five No’s\": Do not proceed if the equipment is not properly lubricated, if the tools are incomplete, if the operating procedures are not clearly explained, if the records are incomplete, or if the hygiene standards are not met.

1. Understand the main operations for the shift, as well as the instructions from workshop leaders and dispatchers, through the shift handover book. 2. Changes in the raw materials used in the previous batch, product quality, and corresponding adjustment measures. 3. Several key data trends in the hydrogenation unit, such as changes in the circulating hydrogen volume before and after the furnace, the reaction feed rate, backwashing time, and reaction CAT, etc. 4. Understand the operation of equipment through large-scale unit systems.

Ensure that the operating conditions of all equipment and instruments are as described by the person handing over the shift, and that the cooling water for mixing is flowing properly

Conduct pre-shift inspections in advance each day, carry out inspections every hour during the shift, fill out the inspection records (Hydrogenation Unit Inspection Form), and update the on-site inspection signs on time. Inspections are carried out using the methods of “looking, listening, touching, and smelling”. “Check the compressor current, pressure, inlet and outlet pressures at each stage, water pressure, filter pressure difference, cooling water temperature, bearing temperature, and the oiling condition of the oil injector, as well as look for any leaks on site. “Check whether the current, pressure, temperature of the pump, the condition of the cooling water, oil level, as well as the high and low liquid levels and interface levels of the static equipment, along with their temperatures and pressures, and whether there are any leaks on site, are all within the specified ranges. “Listen for any abnormal noises from the various pumps; if such noises are present, identify the cause and address it promptly. “Feel the temperature and vibration of the bearings and motors of each pump. “Smell to check for any unusual odors at the site of various mechanical devices.

Is the device production stable, and do the products meet the production requirements without any defects?； Are all the moving and stationary equipment, as well as instruments and electrical devices on site, complete and undamaged? The on-site inspection shows normal conditions ； Have there been any changes in the process parameters and raw materials used in production, and are there any specific requirements for production from the workshop? ；
