Fluid bed granulation
Stamicarbon's fluid-bed granulation technology has been licensed over 15 times for commercial scale plants, including capacities exceeding 3500 mtpd. more
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. Revamping or
debottlenecking urea plants depends on the availability of
feed stocks and utilities.
Because this availability of feed stocks and utilities are different at every site, Stamicarbon developed several revamping concepts. From these revamping concepts the following expectations about capacity increase are given as a ballpark figure in the following table: Concept type Expected capacity increase % More in more out 10 - 25 The double stripper 30 - 45 The MP add-on 35 - 50 The pool condenser 40 - > 100 The reference for the given capacity increase is the nameplate capacity. It should be noted that the achievable plant capacity increase depends on the original used design margins of the large capital equipment.
