Magma
Soda Ash
Crude Bicarb17-18.5% Moisture Return Ash
Current Scenario:
Bicarb Cake has residual moisture of 17 – 18.5%
Approximately 40 - 45% of the generated HP steam is consumed at the Calciners
Existing Schematic
ICI Pakistan Limited is now part of the AkzoNobel Group 3
Centrifuge
Proposal: Installation of a centrifuge downstream of the rotary filters
Purpose: Reduce the steam consumption at the Calciners by reducing the moisture content of the Bicarb Feed

Centrifuge
Ferrum Proposes Pusher Centrifuge
Moisture reduction 17% to 12 % on Calciner 3 & 4 & 18.5% to 13% on Calciner 1 & 2
Benefits:
Steam consumption on the basis of designer specifications reduces 0.05 T PTA
Moisture content in Bicarb will increase the operating life cycle of the Calciner
Vendor: Ferrum, Switzerland
Centrifuges at RSB from Ferrum
