LUNDBERG SOAP CONCENTRATOR


Separation of soap from black liquor frequently produces a soap density of one to three
pounds per gallon. The Lundberg Soap Concentrator can increase soap density to as
high as eight pounds per gallon, resulting in reduced soap storage requirements. In
addition to savings in storage, typical concentrator installations include: weak black liquor
oxidation Systems, foam control systems in washing plants, following evaporator skim
tanks that have been aerated to improve soap flotation, and in soap processing systems.

The Concentrator is one of the two mechanical foam breakers that Lundberg engineers
have developed for foam control systems. The Concentrator has been designed to
operate on light, soap-rich foam common to black liquor from pulping resinous woods.

The Concentrator is a disc bowl centrifuge which deaerates the light soap by breaking
down the highly viscous small soap bubbles. The unit normally operates at 150 pounds
per minute. The discharge density normally averages five to seven pounds per gallon or
higher.
