Anqing Petrochemical eliminates lack of pre-hydrogenation safety shields

In order to ensure the safety of festival production during the Spring Festival, prior to the holiday, Anqing Petrochemical Refinery II conducted a unloader replacement treatment on the I-set hydrogen saturation reactor 001, cut out the reverse 001, discharged the old catalyst, and replaced the new one. And smooth investment, the entire production process a smooth transition, product quality has also been guaranteed.

Previously, due to the increasing pressure difference of the 001 differential pressure in the I-saturated hydrogenation reactor, the effect of hydrogenation reaction was affected. In order to ensure normal production and product quality, it was necessary to carry out crowning on the reverse 001. The application of the I-hydrogen saturation reactor effectively protects the I-set of the hydrogenation reactor 101, preventing the increase of the differential pressure of the coking catalyst in the bed, and avoiding the suspension of treatment that will affect the normal production. In the absence of work stoppage, The filter can be processed by directly cutting out the furnace filter.

In addition, during the Spring Festival, the hydrogenation unit of the second refinery began with pre-holiday equipment and HSE inspection, and took all effective measures to overcome the unfavorable factors such as the fluctuation of the gas pipeline network and ensured the safe and stable production of the device. Pre-holiday and second-hand pumping personnel performed detailed inspections on the equipment and HSE conditions of the equipment to ensure that the pumps were in good operation and standby condition. The large-scale units and special equipment were managed properly. The combustible gas alarm and fire alarm system were in good condition. Hidden risks registered on the Internet timely rectification, the implementation of safety precautions, does not make the device sick. During the Spring Festival, in response to the new round of cooling weather, we will do a good job of on-site anti-freezing and anti-coagulation and anti-slip work. At the same time, we will carefully compare the on-site liquid level, boundary, and indoor DCS to prevent instrument artifacts. For the key equipment III hydrogenation cycle machine K-302, raw material pump and other strengthening monitoring, pay close attention to changes in temperature, sealed steam, with liquid and other conditions. The second department also requires the technicians to keep the mobile phone unblocked, so that there is a problem 24 hours to report at any time.

Due to the shutdown of a set of equipment in coking, the amount of gas is reduced, and due to the influence of factors such as more liquid, pressure fluctuations, and the use of liquefied gas, the temperature of the I set of hydrogenation is not well controlled, so as to avoid affecting product quality and causing Equipment damage, the operator pays close attention to the DCS operation screen, the important parameters are changed manually, the on-site and indoor adjustment are combined, and the inlet temperature is stably reacted to ensure the smooth production of the device.

The recently installed television monitoring system in the two hydrogenation operations rooms, through the installation of 13 electronic cameras at the site, implements all-round and full-process monitoring of the entire hydrogenation plant on-site towers and pumps, and the sudden and abnormal conditions on the site. The ability to timely discover and handle in a timely manner is like adding a solid protective cover to the site's production safety, thus ensuring safe and stable production during the holiday season.
