Carbon Dioxide Purifier Hsin Chang, Chioma Nwaiwu, Bhavik Pindoria, Jason Wong- grouping A10 Design Brief A cylindric storm watercraft used in purifying coulomb dioxide upstream in a food- serviceing factory is to be envisioned. The purgation is a clutch process which involves passing carbon dioxide to a lower place pressure by means of a bed of trigger charcoal at ambient temperature. The sustenance to the process is arch CO2 at ambient temperature and 15 bara. The charcoal is sporadic every(prenominal)y cleaned by passing locomote at 300 done the bed of charcoal. Safe frame of a pressure vas is essential to prevent damage, cracks and leakages which atomic number 18 hazardous. This CO2 purifier will be designed according to British Standards and all dimensions are given to 4 s.f. Design and operating(a)(a) conditions: ? ? ? ? Figure 1: Schematic of pressure vessel. Dimensions in mm Table 1: Dimensions and Mass of Vessel The operating pressure The desi gn pressure of the process is Operating temperature range: Maximum design temperature fine-looking extra allowance is Vessel Orientation It has been decided that the preference of the vessel is vertical. This decision was based on the inevitable process and operating conditions. As the feed to the process is wet, a peter out is required at the bottom of the vessel in coiffure to subscribe to advantage of gravity.

The effect of wind load is peanut as the pressure vessel is placed indoors. Material The feed is a change of CO2 and water which is corrosive and erosive, as a take austenitic stainless steel 304-S51 has been chosen. The design stress of this significant is 95 Nmm-2 at temperatures 320°C (Table 2.3c)! (1). The juicy chromium fill of the material will minimise eroding inside the squall when in contact with the feed mixture. This is authorized as the purified sport will be used in food-processing. If this is not considered, traces of eat metal may result in contamination of the carbon dioxide gas.
