2. Practice design for the supercritical fluid extractor pressure vessel and a vapor-liquid separator assuming only two fluids: carbon dioxide and citric acid solution. For a plant that processes 4867Mgfy ash /year(0.7Mg/h), the extraction vessel requires 2240kg/hCO2 and 60.2kg/h citric acid solution. The extraction vessel is 2m tall with an inner diameter of 0.75m. The densities of supercritical CO2 and 1M citric acid solution under the process conditions (315325K,1525MPa) are 662kg/m3 and 1070kg/m3. The density gaseous CO2 at 2 bar and 315K is 3.5kg/m3. The viscosity of CO2 is approximately 10.5 Pa.s as supercritical fluid and 1510.6Pa5 as a gas. Approximate the properties of the citric acid solution as water. A. Estimate the thickness of the cylindrical shell and the vessel weight (with head) if the vessel were made of 304 stainless steel. State your assumptions (you will need several). B. Estimate the diameter of a vertical vapor-liquid separator to be placed after the extraction vessel, where the temperature and pressure are approximately 315K and 2bar, and the goal is to remove 100m droplets. Examples 23.2 and 23.3 may be helpful. C. Estimate the gas velocity exiting the vapor-liquid separator. D. What would you recommend for an inlet device and mist eliminator if the recovered CO2 is eventually going to be compressed for recycling
