The company imported two sets of synthetic ammonia and two sets of urea plants from South Korea Nanhai Chemical Co., Ltd., and a set of large granular urea plant from Holland for production. After introducing the world-advanced patented technology of casali to transform the internals of the synthetic tower, the key equipment of the synthetic ammonia plant, the daily output of a single plant is 1000 tons, and the comprehensive energy consumption per ton of ammonia in the synthetic ammonia plant is reduced from 10 gcal before the transformation to 8.5GCal, which has entered the leading ranks of similar plants in China in terms of energy saving. The urea plant adopts the world-famous patented technology of Stamicarbon 2000+CO2 stripping in the Netherlands and large-scale synthetic ring process, and adopts a new patented corrosion-resistant material Safure, which can realize anaerobic operation.
At the same time, the automatic control system of the project has also undergone a large-scale transformation. 1 1 The compressor unit adopts the most advanced ITCC automatic control system, and all the control systems are changed to the most advanced DCS distributed control system (the fourth generation technology).
