USE OF BAGHOUSES IN A DAP PLANT
PH-O-11
Baghouses have not commonly been used in DAP plants. However it is possible to employ them as an alternative to
cyclones and wet scrubbers in certain circumstances. This paper examines the most appropriate airstreams within
the plant for the application of baghouses and discusses the pros and cons for their use in each case including an
economic assessment for a specific example.
The paper also discusses the necessary design features for the successful use of baghouses

Innovations to the existing production of DAP are related to capacity increase, energy, saving and easiness of
operation. New pipe reactor, less recycle ratio, additional cooling and coating system and new performant effluents
treatment system allow to achieve high quality product. SNC performed the study from conceptual stage up to EPC/
EPCM contract realisation. The philosophy that has been respected for the increase of the capacity remains in the
fact to keep the same recycle back to the granulator but with lower recycle ratio.
This paper describes the different steps during the design, commissioning and start up problems till successful hand
over of the plant.
