Analysis of volatile organic acids in vapour condensates from a low-grade vacuum pan at Mulgrave mill
By Pope, GM; Rich, B; Papageorgiou, J; Doherty, WOS; Edye, LA
The composition and concentration of volatiles produced in a low-grade vacuum pan at Mulgrave Mill during crushing periods and maintenance stops have been determined using high performance liquid chromatography (HPLC). The organic acid contents of massecuite samples were determined and compared to the analysis of the vapour condensate samples. This paper presents the results and recommends strategies that would reduce corrosion of low-grade pans constructed with mild steel.
