By March 29th, Sichuan LAN-STAR mechanical design, the overall production of the largest 300000 tons / year urea device -- DN1800 model energy-saving urea synthesis tower loading shipped. The device adopts the heat transfer process of liquid phase flow, carbon dioxide conversion rate of more than 72%, compared with the domestic water solution total recycle urea unit, the comprehensive energy consumption per ton of urea product can save standard coal 70.3 kilograms, more than 21000 tons of standard coal saving.

According to reports, the urea synthetic tower is nearly 36 meters long, 1800 mm in diameter, weight of nearly 350 tons. Environmental protection safety device, 5ppm is less than urea and ammonia content in the wastewater, and no efflux; inert gas scrubber ammonia concentration as high as 72%, fine scrubber operating pressure is only 0.7MPa, can be used for the transformation of existing water solution total recycle urea process device or a new project. The equipment will be put into use in the Sichuan Dazhou Jiuyuan chemical industry limited company 300000 tons / year urea project.

It is reported that, after the equipment in the factory section manufacture, welding, assembly, and the site condition, the production time and cost increase. LAN-STAR machine in the successful development of WHG gasifier, Ning coal and other large equipment and implement in the factory assembly and overall after delivery, the energy saving of urea synthesis tower of the whole production process innovation, mode, completed the design, production, installation of the "one-stop" service, greatly shorten the production cycle to save costs, making a million, technology has reached domestic advanced level, but also save the time for the client device operation.
