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

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

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
