Combustion Control in a Black Liquor Boiler

Tuesday, February 14, 2023 | Derek Stuart

Application

The kraft process is widely used to convert wood into pulp for papermaking. The process is very efficient because most of the chemicals used to process the wood can be recycled. In the process, the lignin and hemicellulose are separated from the desired cellulose fibres.

What Are NOx and SOx and Why Are They Important?

Friday, February 18, 2022 | Derek Stuart

Industry

The terms "NOx" and "SOx" are often seen in emissions measurement specifications, but many people are unsure of their accurate definitions. The terms come from the study of atmospheric chemistry, and each refers to a family of compounds.
