Black Liquor is the digester waste mixture of spent chemicals and lignin extracted from wood chips. When burned in a recovery boiler Black Liquor produces heat for steam and also releases digester chemicals called "smelt." Mixed with water, smelt becomes Green Liquor. This is treated with lime in the causticizers to produce White Liquor, the digester’s cooking chemical.

Under Deposit corrosion (UDC) is one of the hardest types of corrosion to identify and a common mode of failure in boiler tubes. UDC is not only a high risk of eventual tube failure but it can also be deadly in black liquor recovery boilers. The biggest issue: it can't physically be seen. This localized corrosion was happening at a paper mill in eastern Georgia.
