Look at the great development of chemical equipment in the past ten years and praise China's prosperity and prosperity. Replies will be rewarded and discussed. ---------------------------------------------- On November 15, the first loop reactor of the Tianjin Nangang ethylene 200,000 tons/year LAO unit, the largest domestic linear alpha olefin production unit located in Nangang Industrial Zone, Tianjin Economic Development Zone, was successfully hoisted in one go through a single 6-set loop pipe "Sun" shaped integral frame assembly method. This is the first time in China. This method of hoisting reduces the safety risks of high-altitude operations, shortens the construction period, and opens a new chapter in domestic loop reactor installation. The 200,000 tons/year LAO unit is one of the 13 units under construction in the Tianjin Nangang Ethylene Project. The loop reactor is the core equipment of the unit, and its design and installation quality are directly related to the long-term smooth operation of the unit. The device has a total of 2 loop reactors, each reactor is composed of 6 reaction tubes connected in series, with a total weight of more than 320 tons. This hoisting abandoned the conventional installation method of single-chip single-chip crane, and innovatively adopted a new hoisting mode of integrally prefabricating the loop reactor and "Sun"-shaped group frame. Since the reactor is overall arranged on a concrete frame with an elevation of 6.8 meters, the installation accuracy is extremely high. In order to ensure the successful completion of the installation task, Tianjin Petrochemical worked with participating units to deeply optimize the reactor design plan, conduct in-depth discussions on the installation of the reactor's basic positioning template, and review the installation position of the positioning template multiple times to ensure that the design accuracy and prefabrication accuracy meet the needs of manufacturing, construction and installation, and the reactor was successfully hoisted in one go.
