China Construction and installation company realized the largest monomer hoisting in the national scene production
January 11, 2015,China Construction & Installation Engineering Co., Ltd.
(hereinafter referred to as the construction company) is responsible for the construction of 500 thousand tons / year Hebei Haiwei PDH project (hereinafter referred to as Hebei Haiwei project) 2# separation tower to finish smoothly.
Hebei Haiwei Group Limited 500 thousand tons / year PDH project in Hebei province is the focus of the project, is the first device in the United States Lummus process complete localization of the domestic, one of the 3 sets of propane dehydrogenation unit is also the country's largest. The project is located in Hebei Hengshui Hengde Industrial Park North, device using propane dehydrogenation technology of American Lummus company, after the completion of the production of propylene by propane dehydrogenation technology, which accords with the national comprehensive utilization of energy and environmental protection industry policy, and can alleviate the current shortage of domestic propylene supply is of great significance.
As the main construction unit Hebei Haiwei project, making installation and debugging engineering construction company responsible for the main equipment, production and installation of the number reached more than 150 sets of equipment, including 5 sets of reactor are 100 tons of equipment, 2 sets of product separation tower to achieve ultra kiloton level, core equipment is also the most difficult project, hoisting equipment. The reactor and the separation tower are made on the spot by China Construction and installation company. Therefore, in the construction company to chemical equipment manufacturing plant to the site, built 3360 square meters of a total of 4 sets of automatic mobile plant, 50 tons gantry crane, 10 sets of ESBA equipped with 3 span 40 meters full automatic welding machine and other advanced equipment, on-site production of 17 complete sets of large equipment. The 5 reactors single weight 270 tons, 7.9 meters in diameter, about 20 meters long, by the construction and installation company of Italy CR company, Lummus company in the United States for the first time in the United States Lummus joint manufacturing process completely localization, product quality, manufacturing cycle has been unanimously praised the U.S. senior engineer; 2 sets of product separation tower the height of over 81 meters, diameter exceeded 8 meters, among them, 2# separation tower total weight of 1335 tons, 1# total weight of 1412 tons of separation tower. The project adopts the lifting scheme of 2600 ton gate type hydraulic lifting system as a whole lifting and 750 tons crawler crane matching tail chute.
The separation tower is the largest chemical equipment monomer produced in the whole country so far, which has created a precedent for the field production of super large equipment in the national petrochemical industry. The separation tower is also the highest and heaviest chemical equipment monomer lifting in the middle of the whole building. The hoisting technology of the portal hydraulic lifting system is used for the first time.
