In the year of 1969 Chemoprojekt and Stamicarbon concluded a licence and know how agreement, enabling Chemoprojekt to design and construct urea plants on the basis of the modern Stamicarbon CO2 stripping technology.
Chemoprojekt has been successful from the beginning in design and start up of a number of urea plants. Already in the year of 1970 first two contracts for the fertiliser factory VEB Stickstoffwerk Piesteritz in the East Germany were concluded. The first free units with the capacity of 1050 MTPD each were designed and successfully put into operation. Further on a row of the other urea plants followed.
Up to the present time Chemoprojekt has designed together 19 new units and 2 intensification projects ever since based on the Stamicarbon urea process. Chemoprojekt is one of the selected Stamicarbon s contractors for urea. The single unit capacities, designed by Chemoprojekt, range from 1000 up to 1670 MTPD. Six of the plants were designed for production of urea with low biuret content using the technology of crystallisation and melt prilling. The other units are usual processes with evaporation and melt prilling, producing urea with standard biuret content.
