Abstract

Slag is a mixture of mineral in tin sand or by product in the smelting process. By using separation process, tin can be separated from other minerals in slag. Extraction process with a solvent is usually used to separate tin from other minerals. Furthermore, solution that still contains many dissolved compounds is adsorbed by activated carbon and desorption back with NaOH solution. This study only focuses on the extraction process to obtain a stannate chloride solution with extraction temperature, solvent concentration, extraction time, and liquid/solid ratio as variables. Hydrochloric acid (HCl) has been used as solvent in this study. The concentration of tin in the extracts of each variable was analyzed to determine the percentage of recovery of tin and the optimum operating conditions in the recovery process of tin from waste slag. Experiment results show that the percentage of recovery increases with the increasing of extraction temperature and solvent concentration The highest recovery is 61.5% which is obtained when the extraction temperature is 80 ºC, concentration of HCl is 10 wt%, with a HCl solution and slag ratio is 7: 1 and extraction time is about 30 minutes.

Abstract

Membrane-based desorption of carbon dioxide (CO2) using a membrane contactor is considered a novel process for separating CO2 from solvents. It can be carried out using temperature regeneration, sweep gas, and vacuum method. In this work, the vacuum regeneration method is applied in the CO2 desorption process from 30% wt of diethanolamine (DEA) solution. This study investigates the effect of operating parameters such as liquid flowrate, vacuum pressure, and CO2 loading on the mass transfer rate and desorption efficiency of CO2. The highest mass transfer rate of 2.2013 × 10-7 mol/m2s is achieved at a liquid flowrate of 500 mL/min, CO2 loading of 0.27 mol CO2/mol DEA, and vacuum pressure of 50 cmHg while the maximum desorption efficiency of 71.45% is achieved at lower liquid flowrate of 100 mL/min, CO2 loading of 0.27 mol CO2/mol DEA, and vacuum pressure of 50 cmHg. The result demonstrates that membrane contactor is a promising method for the CO2 desorption process which requires further investigation.
