At 17 o'clock on the afternoon of November 4, the refinery division light white clay refining device produced qualified lubricating oil products, which marked the successful upgrade of the DCS system of the device. After more than 10 hours of verification by the opening steam, the newly upgraded DCS operating system was safe. Go to work.
The lightweight white clay refining device upgrades the DCS operation monitoring system by using the heavy lubricating oil system overhaul. Compared with the old system, it eliminates the incomplete display of some operating data of the old system, and the system valve opening is not flexible enough. DCS operating system, there will be an audible prompt when the process indicator generates an alarm. The alarm information is indicated in the alarm bar and the process alarm window.

"Installation Shutdown Program", "Purse Safety and Environmental Protection Program", "DCS Project Matching Risk Assessment" and other measures, the team leader, the establishment of the party group HSE supervision team, the placement of materials for construction fire points, construction tools Strict management and control, such as placement and parking of foreign vehicles, so that every link is put in place, and no unsafe steps are missed.
In this short-term stoppage, the HSSE supervision of the party and the group carried out full-time monitoring of the project construction, and found more than 10 unqualified items during the construction. The process professionals and the instrument installation and deployment personnel carried out face-to-face wiring inspection, and checked the instruments of each connection. If the workload is large, they work overtime. Every day, the professional check the instrument number of each pipeline, each tower and each container. The on-site wiring was carried out in an orderly manner, which provided a safety guarantee for the resumption of the DCS upgrade of the light-white clay refining device.
