Rheological Properties Of Solutions In The Production Of Potassium Sulfate

This study investigates the rheological properties and phase separation characteristics of solutions during potassium sulfate production through the conversion process involving potassium chloride and ammonium sulfate. The research focuses on the clarification kinetics, filtration rates, and solid-liquid separation efficiency in multi-stage conversion processes. Experimental investigations were conducted using graduated cylinders and Buchner funnel filtration systems to evaluate settling velocities and filtration characteristics. Results demonstrate that suspension clarification on the second stage reaches maximum values of 66.25% within 95 seconds, while filtration rates vary from 1000-1200 kg/m²·h for the first stage to 2100-2300 kg/m²·h for the second stage. The study reveals that temperature elevation from 20°C to 60°C and molar ratio adjustments from 1:1 to 1:2 significantly influence filtration efficiency. These findings provide crucial insights for optimizing industrial potassium sulfate production processes through enhanced understanding of suspension rheology and phase separation mechanisms.
