  CO2 stripping plants

  When the present operation of the urea plant should be integrated into the revamp, Stamicarbon performs a revamp study, in order to examine the present performance of the plant and to investigate the optimum solution for the revamp and integration with the original plant design. It is important to consider a debottlenecking or revamp project because it is very attractive to take full advantage of all the design margins available in order to produce more urea. This will lead to a maximum production level in a rather costly process installation. A higher production level will be achieved with the same number of people, the same infrastructure and the same buildings. The total fixed costs can be divided by more tons of urea leading to a lower cost price of urea. This is also a reason that the sizes of grass root plants are nowadays growing significantly.

  Non CO2 stripping plants

  The main reasons for revamping Non-CO2 stripping plants (also called: heat stripping or ammonia stripping) are increasing the reliability and increasing the capacity of the urea plant. The design capacities could be raised by more than 50% by using the Stamicarbon revamp technologies such as Pool condenser and Double Stripper concept.
