This reactor is the centrepiece of Stamicarbon’s LAUNCH MELT™ Ultra-Low Energy Design, which allows for substantial energy savings. The reactor embeds two heat exchanging tube bundles and makes use of SAFUREX®, a stainless steel for high pressure equipment in the synthesis section in urea plants.
Most urea processes until now have been based on a so-called "N=2" heat integration design, in which the heat supplied to the plant is used twice.The Ultra-Low Energy Design is based on a "N=3" design, in which the heat supplied in the form of high pressure extraction steam is used three times. The steam consumption is reduced by about 35% and cooling water consumption by about 16%, compared to other present-day urea plant designs. The design requires only two high pressure synthesis equipment (reactor and stripper). Aside from bringing significant reductions in the operational costs of urea plants, this technology offers major environmental benefits, because it reduces both energy consumption and greenhouse gas emissions.
The Ultra-Low Energy Design is not only suitable for new plants, it can also be used as a powerful revamp tool for both CO2 stripping and conventional urea plants. Stamicarbon has been awarded contracts for implementing the design in three grass-roots urea plants.
