What is a pond-type reactor for urea, and what are its characteristics? ?
Thread Content
On April 1, 2013, with the successful installation of the pool-type reactor for the urea production facility, the installation of the last large-scale equipment for Shaanxi Chemical Group’s coal chemical industry energy-saving and emission-reduction renovation project was completed. The facility then entered the testing phase, with the production of qualified urea products expected to begin in the first half of the year. The reactor is 31 meters long, has an inner diameter of 3.5 meters, and weighs 366 tons. The urea plant employs the carbon dioxide stripping production process developed by Stamicarbon in the Netherlands. Horizontal tank reactors are used in place of traditional vertical synthesis towers, which not only significantly reduces the height of the plant’s structure and saves on investment costs, but also simplifies operation and maintenance.

The text states that \"by replacing traditional vertical synthesis towers with horizontal tank reactors, the height of the plant framework is significantly reduced.\" The reactor vessel on the left is smaller; to achieve the same production capacity and separation efficiency, a taller tower would be required. The structure on the right has a larger cross-section at the bottom, which is beneficial for the reaction and allows for preliminary separation; therefore, it does not need to be that tall
A combination of horizontal and vertical? ? ? ?
I guess so; if a fully bedded design could solve the problem, there’s no need to use a traditional design with a standing structure
On October 7, the core equipment of the urea production unit in Hubei Sanning’s ethylene glycol project, namely the tank reactor R202, which was constructed by the Group Company’s Chemical Engineering Division, was safely placed into its main framework in a \"princess hold\" position. The equipment is 32 meters long, 4 meters in diameter, and weighs 460 tons. Under the supervision of relevant officials from the owner Hubei Sanning Chemical, Shandong Haohua Supervision, Anning Lifting Company, Henan Installation, and others, the team at the command post worked together diligently. The process involved securing the equipment, removing it from the transport vehicle, rotating it, lifting it smoothly, and positioning it firmly. Despite a lifting weight of up to 480 tons (including the lifting gear), the equipment was safely and smoothly lifted onto a 24-meter-high structural frame.
It is understood that the urea pool reactor is the core equipment of the world’s advanced ultra-low energy consumption urea production process. It is manufactured from the SAFUREX material recently developed by the Dutch company Stamicarbon. Thanks to its innovative \"horizontal tower + dual U-shaped tube bundle\" design, it set off from the manufacturer in August and, after traveling via a combination of land, sea, and river transport, was unloaded at a Yangtze River port; after a long journey, it finally arrived at the ethylene glycol production site on October 6th. Length, weight, and diameter are known as the “three biggest” characteristics of the project.
