On November 15th, the first batch of 150,000 tons of ethylene cracking furnace of Dushanzi Petrochemical Co., Ltd., which was contracted by China Ryukyu Engineering Co., Ltd., started the low-temperature oven, which laid the foundation for the next year's production. The ethylene cracking furnace is the leading device of the million-ton ethylene project of Dushanzi Petrochemical. It is the same type of equipment with the largest single cracking capacity in China. The cracking technology adopted by the device belongs to the high-end technology of refinery chemical equipment, with many kinds of materials and high construction requirements. Low-temperature oven is an important part of winter construction, mainly to remove the residual water in the furnace tube, avoid freezing the furnace tube, and ensure that the furnace tube is safe for the winter. At the same time, by slowly heating and heating up, the moisture accumulated in the furnace wall is removed, and the life of the furnace wall and the refractory material is improved. In order to ensure the safety of construction in winter and smoothly advance the process of low-temperature oven, the cracking furnace project department of Liujian Company grasps the key points and key difficulties of winter construction, carefully prepares for winter construction, prepares detailed winter construction plans, and strengthens quality and Safety management, carry out joint inspection and cross-check of quality and safety; implement safety education and training for construction workers and safety construction technology in winter; strengthen technical quality management in all aspects and at multiple levels, technicians conduct comprehensive follow-up inspection of the whole process, and immediately coordinate and rectify problems Carefully analyze the risk factors of winter construction, plan HSE safeguard measures in detail, and implement the protective measures. The cracking furnace construction technology is the high-end technology of chemical equipment. Especially the welding and installation of the radiant section furnace tube, the cracking gas large pipe, the oil transfer line and the ascending down pipe are the construction difficulties and key points. To this end, the project department launched the “Dagan 100 Days†labor competition, using the national first-level construction method of modularization of cracking furnaces, organizing expert analysis meetings, conducting technical difficulties, optimizing construction plans, strengthening welding process evaluation, and welding welders. Specialized technical and simulation training was carried out, and the “first three must-check†measures were implemented to promote construction safety, quality and progress with advanced construction technology. The qualification rate of welding once reached 98.6%.
