Analysis of the Factors Affecting the Oil Recovery from Oilseeds in a Multistage Crosscurrent Leaching Process
Abstract
The analysis of the total oil recovery from oilseeds in a multi-stage crosscurrent leaching process is presented. The model created using mass balance equations for three stages was used to analyze the factors affecting total oil recovery, To. The key performance factors (raw meal feed flow rate, solvent feed flow rate in each stage, solvent distribution factor for each stage, percent oil in the raw meal (Poil), solids to solution ratio in the underflow (N), solvent to solids ratio (SSR), solvent to oil ratio (SOR) and wash ratio (WR) were varied while assessing To. While SSRiand SORiranged from 0.1 to 10 and from 0.1 to 100, respectively, N varied between 1 and 7. The variation of Towith the key variables were fitted using polynomial functions, whose degreeincreased with N at fixed values of solvent feed flow rate (Vs) and raw mealflow rate (F). Towas the highest when1and2 ranged from 0.05 to 0.3 and 0.05 to 0.2, respectively. The highest percent contribution to Towas from Stage 1 (50 -80%) followed by Stage 3 (10 to 40%). Optimal settings for the newly introduced parameters (SSRi, SORiand 1) and solvent distributionfactors are recommendedfor maximizing the total oil recovery.
