Construction and Design
The Liquid/Liquid Extraction Apparatus OperatiX - 11 is built around a glass extraction column in two parts, 40mm in diameter and 1000mm in height. A distillation unit is fitted with a packed column and a distillation bridge with a condenser in a heated round-bottomed flask, 50mm in diameter and 400mm in height. Two pumps handle fluid delivery: a feed pump rated at 1000ml/min with a 40m head, and a solvent pump rated at 2000ml/min with a 10m head. Two three-way valves allow switching between continuous and discontinuous operation. Two valves fine-tune the phase boundary within the extraction column. A water circulation vacuum pump with 2 vacuum ports supports vacuum operation during distillation, reaching a final vacuum of approximately 200mbar. PID control governs electrical heating, with a bottom heater power output of 1.2kW. Stainless steel tanks hold feed, solvent, raffinate, and extract, each approximately 20L, while the top product tank for distillation is made of glass at 2.5L capacity. A bottom tank for distillation holds approximately 5L. Raschig rings increase heat transfer surface area in the extraction and distillation columns.
