BLACK LIQUOR EVAPORATION PLANT UPGRADES

Rinheat has long experience on the reboilers for Thermo Mechanical Pulping (TMP) Process and evaporators for the liquor from Chemi Thermo Mechanical Pulping (CTMP) plants. On the basis of this knowhow we have developed better main constructions for the black liquor evaporation:

OT Concentrator with liquor flow on the outside of the vertical tubes
CS Evaporator with condensate stripping
CC Condenser with counter-current flow

BENEFITS

The patent for OT Concentrator and CS Evaporator has been awarded and the patent for CC Condenser is pending. Rinheat evaporators have the following common benefits and features:

Good quality secondary condensates

Low steam consumption

High dry solids

Small foot print

KEY TECHNOLOGY FEATURES

Non-plugging tubular OT Concentrator
Good secondary condensate segregation in CS Evaporator
Efficient falling film CC Condenser
Integrated foul condensate stripper

OPTIONS

More capasity and steam saving through additional effect on the existing evaporation train
Retrofitting new heat transfer surface into an existing body
