Production of sulfuric acid from incineration of pulp mill NCGs
The production of sulfuric acid from pulp mill NCG enables a bioproduct mill to become nearly self-sufficient in sulfuric acid usage. Sulfate led to the mill's effluent treatment plant is reduced and the sulfate load to nearby waterways is decreased drastically. This innovative plant can produce sulfuric acid and bisulfite simultaneously depending on the requirement. The internal recycling of chemicals can reduce purchasing by 350 truckloads of acid per year.
