The Rotoform process offers high flexibility in urea production and opportunities to add value to your existing urea products, with low investment and operational costs, low energy consumption, negligible emission figures and premium product quality. One or more Rotoform units can be added in parallel to the existing finishing system at any time. The Rotoform process is a good technical and economical method of debottlenecking or revamping existing urea finishing units.
Furthermore, it’s possible to add value to the product by producing specialty fertilizers in a parallel line.
For new grass root urea plants Rotoformer technology offers besides the significant advantages such as negligible emission figures and low investment and operational costs, also other advantages such as no risk for large scale applications as it is simply several Rotoformer units in parallel. The Urea Rotoformer has been successfully in operation in several units for more than four years and the large scale application has been proven for Sulphur (46 units in parallel). By adding one or two units extra in parallel to enable regular maintenance of each unit, one is able to assure an availability of 100%, meaning an on stream time of 365 days a year.
This paper focuses on the process technology aspects while the next paper will focus on the product properties aspects.
