Scope and content
Two Swenson evaporators and pipes at St. Regis. The molten substance left after the "Black Liquor" burns through the furnace is called "Green Liquor." The green liquor is sent to the caustic department, where the insoluble matter settles out, also the calcium carbonate, and a clear white liquor is made. This liquor is the original one used in the "cooking process" to separate sap & pitch from cellulose fibers and the recovery and recycling is complete. (TNT 2-17-1952, pg. C-14)
