The Advanced Urea On-Line Raman Analyzer (AURORA) is a new powerful tool for on-line process analysis and control of urea plants developed by Casale in cooperation with Kaiser Optical Systems Inc. – a company of Endress+Hauser group, worldwide leader in the spectrographic instrumentation.
Ammonia Absorption Refrigeration Plants (AARP) are refrigerators that use low value heat sources (like low pressure steam or even hot water) to power the refrigeration process instead of using compressors, which, on the other hands, require high grade thermal energy (like MP steam) or electrical power.
The AN based fertilizer granulation process allows, in the same unit, the easy granulation of ammonium nitrate (AN), calcium ammonium nitrate (CAN) with possible elemets addition like Mg, S, etc., ammonium sulphate nitrate (ASN) and also 34.5% ammonium nitrate for technical uses.
Casale can offers a combined tail gas treatment system with both DeNOx and DeN2O catalysts to treat tail gas and achieve requested environmental regulatory limits.
Steam reformer is one of the most critical unit in the hydrogen, ammonia and methanol plants. It is complex, energy intensive, very expensive and by nature its design is often aggressive, due to the need for harsh operating conditions and specialty materials.
Leveraging on Casale’s specific know-how and experience with all commercially available CO2 removal section technologies, either amine-based or hot potassium carbonated based, Casale can assess the performance of existing units with the goal to identify bottlenecks, suggest improvements and propose revamp solutions.
To obtain AA grade methanol, the final purification of the crude is performed with a two-step distillation: the first column, named topping, separates the lighter compounds, while in second column (refining) water and higher ends are separated from the pure product.
