Hydrogen (H₂) is considered a clean energy carrier. For its use as a fuel, hydrogen is stored at 5 bar insidea cylindrical tank made of nickel (Ni) with 7 cm inner diameter, 1.2 mm thickness, and the length of L. Thetank is maintained at 358 K. Unfortunately, a small amount of hydrogen diffuses out of the tank, slowlydepleting its contents. You may assume that the hydrogen pressure outside the tank is essentially zero andconvective resistance inside and outside of the cylinder is negligible.• Solubility of H2 in Ni at 358 K = 0.00901 kmol/m3·bar• DH2, Ni at 358 K = 1.2 x 10-12 m2/sCalculate the maximum length of the nickel tank wall to ensure that the hydrogen loss does not exceed0.01 kg per year.

The volumetric rate of oxygen uptake by the cells ranges from 0.45 to 0.85 mmol l^−1 min^−1 depending on time during the culture. Power input by stirring is 2.9 W l^−1. Estimate the cooling requirements.arrow_forwardProduction of bakers’ yeast Bakers’ yeast is produced in a 50,000-litre fermenter under aerobic conditions. The carbon substrate is sucrose; ammonia is provided as the nitrogen source. The average biomass composition is CH_1.83O_0.55N_0.17 with 5% ash. Under conditions supporting efficient growth, biomass is the only major product and the biomass yield from sucrose is 0.5 g g^−1.

- ▼ Enzyme conversion An immobilised enzyme process is used in an ice-cream factory to hydrolyse lactose (C12H22O11) to glucose (C6H12O6) and galactose (C6H1206): C12H22O11 + H2O →→ C6H12O + C6H12O6 Gel beads containing ß-galactosidase are packed into a column reactor; 2500 kg of lactose enters the reactor per day as a 10% solution in water at 25°C. The reactor operates at steady state and 32°C; all of the lactose is converted. Because the heat of reaction for enzyme conversions is not as great as for cell culture, sensible heat changes and heats of mixing cannot be ignored.

In a continuous fermenter at 28°C with ammonia as nitrogen source, the yield of alginate was found to be 4 g g^−1 oxygen consumed. It is planned to produce alginate at a rate of 5 kg h^−1. Since the viscosity of alginate in aqueous solution is considerable, energy input due to mixing the broth cannot be neglected. The fermenter is equipped with a flat-blade disc turbine; at a satisfactory mixing speed and air flow rate, the power requirements are estimated at 1.5 kW. Calculate the cooling requirements.arrow_forwardPreheating nutrient medium Steam is used to heat nutrient medium in a continuous-flow process. Saturated steam at 150°C enters a coil on the outside of the heating vessel and is completely condensed. Liquid medium enters the vessel at 15°C and leaves at 44°C. Heat losses from the jacket to the surroundings are estimated as 0.22 kW. If the flow rate of medium is 3250 kg h^−1 and its heat capacity is 0.9 cal g^−1 °C^−1, how much steam is required?arrow_forward
