Carbon Dioxide Purifier Hsin Chang, Chioma Nwaiwu, Bhavik Pindoria, Jason Wong- grouping A10 Design Brief A cylindrical compact watercraft used in purifying vitamin C dioxide upstream in a food- act uponing factory is to be envisioned. The purification is a clutch process which involves passing carbon dioxide infra pressure by means of a bed of activate charcoal at ambient temperature. The aliment to the process is miffed CO2 at ambient temperature and 15 bara. The charcoal is periodic solelyy cleaned by passing locomote at 300 through and through the bed of charcoal. Safe frame of a pressure vessel is essential to prevent damage, cracks and leakages which atomic number 18 hazardous. This CO2 purifier will be frameed 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 de sign pressure of the process is Operating temperature range: Maximum design temperature handsome extra allowance is Vessel Orientation It has been decided that the predilection 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 give out is required at the bottom of the vessel in format to subscribe to advantage of gravity.

The effect of wind load is undistinguished 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 significa nt is 95 Nmm-2 at temperatures 320°C (Table! 2.3c) (1). The exalted chromium fill of the material will minimise eating away inside the squall when in contact with the feed mixture. This is main(prenominal) 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.
