Solution
Forbes Marshall carried out a detailed study of the plant,
determined areas of concern and redesigned the entire
steam system. Following changes were implemented in the
new design
- SteaMon vortex flowmeter for steam flow monitoring
incorporated
- The 26 MF dryers were divided into 06 thermal groups,
with 06 individual pressure control stations and
PID-based control valves
- Steam header for thermal groups equipped with compact
module thermodynamic trap, air vent, pressure gauge and
piston valve
- Each of the MF dryers equipped with a complete single
orifice float trap based steam trapping solution
- Separate flash vessels to optimize flash steam recovery
at pre-section and post-section
- Multivalve steam operated condensate pump MV55 to
pump hot condensate
