Revisiting acidulation for tall oil and lignin manufacturing
The Canadian Journal of Chemical Engineering, EarlyView.Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production
