Pulp millWikipedia
A pulp mill is a manufacturing facility that converts wood chips or other plant fiber source into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical semi-chemical or fully chemical methods (kraft and sulfite processes). The finished product may be either bleached or non-bleached depending on the customer requirements.

Advancement of High Temperature Black Liquor Gasification
In the pulp and paper industry black liquor gasification (BLG) can enable the recovery of pulping chemicals and production of syngas from the spent liquor accumulated in the pulping process. The syngas can be converted to value-added fuels chemicals and electricity helping to boost the economics of the pulp mill.

A dynamic Na/S balance of a kraft pulp mill
Normally in softwood mills there is an excess of sulfur and low levels of sodium compared to what the process requires. The unbalance is adjusted in different ways depending on the mill. In the future the pulp mill will most likely produce other products than just pulp which in turn might induce the introduction of new processes.
