Zhejiang Petrochemical Aromatics Phase II Project has a total of 6 centrifugal compressors in the 3# aromatics unit and 4# aromatics unit, 4 of which were constructed by the 213 Project Department. In order to safely and efficiently complete the hoisting and construction tasks of the key “heart” unit equipment of the aromatic hydrocarbon plant, the owner, supervisor and project department attach great importance to it. The project department planned in advance and arranged carefully. The site carefully prepared all the preparations before the equipment came into the site and organized technical personnel. Conduct on-site process disclosure and equipment acceptance checks on compressors.
This time the K-5301 compressor unit equipment overall Upon arrival, it consists of the compressor main engine, steam turbine and base. The on-site equipment is unpacked and inspected. The center line of the equipment foundation is marked. The inclined pads are placed in strict accordance with the technical requirements for large-scale unit construction. At about 2 o’clock in the afternoon that day, as the crisp lifting whistle sounded, with the cooperation of a 650-ton truck crane, the 61-ton centrifugal compressor equipment was slowly lifted and slowly crossed the 15-meter steel structure frame of the compressor factory building. The compressor unit was hoisted cleanly and securely on the foundation, creating favorable conditions for the next step of unit adjustment and testing.
Six pieces of equipment for the second phase of the residual oil hydrogenation unit of the Zhejiang Petrochemical Project were successfully shipped
Recently, six pieces of equipment for the Zhejiang Petrochemical Project were successfully loaded at the Erzhong Zhenjiang Company’s heavy-loading terminal and set off for shipment to users.
The 6 pieces of equipment of the Zhejiang Petrochemical Project are the residual oil hydrogenation units of the second phase of the 40 million tons/year refining and chemical integration project of Zhejiang Petrochemical Co., Ltd., including 2 elution towers and hot high-pressure separators. , cold high-pressure separator, circulating hydrogen desulfurization tower/circulating hydrogen desulfurization tower inlet liquid separation tank, circulating hydrogen compressor inlet liquid separation tank, 1 each. The construction of this project is of great significance to promoting the transformation and upgrading of the national petrochemical industry.
In order to ensure that the project is delivered on time, the production and operation department makes overall plans in advance and combines the actual production to sort out the key and difficult issues of the project and formulate reasonable Production Plan. All departments and units worked together and worked overtime to promote production.At the same time, we arranged party member commandos and key personnel to bravely shoulder heavy responsibilities, overcome all important production links, and complete production tasks with quality and quantity.
This project’s circulating hydrogen desulfurization tower/circulating hydrogen desulfurization tower entrance liquid separation tank is the most difficult piece of equipment to be hoisted this time. This product has a special structure and its total length exceeds the width of the workshop axis. Conventional lifting methods cannot meet the shipping needs. After many discussions between the project leader and the auxiliary section, it was finally decided to use two cranes to hoist to the dock for fixed-point steering, and then switch to a single-hook hoisting solution to the ship.
In order to solve the problem of equipment steering, lifting operators and technicians measured site data on site many times and used software to conduct three-dimensional simulated steering. After many attempts, The exact lifting and turning points were determined. On the day of shipment, with the close cooperation of the lifting and driving classes, the steering was finally completed successfully after 12 hours, and the shipment of the product was successfully completed, accumulating successful experience for future shipments of ultra-long equipment.
At present, 6 pieces of equipment for this project have arrived at the user site and are waiting for installation.
