Question
Q1: Aluminium sulfate is used water treatment and in many chemical processes. It can be made
by rcacting crushed bauxite (aluminium ore) with 77.7 weight percent sulfurie acid. The
bauxite ore contains 55.4 weight percent aluminium oxide, the remainder being impurities. To
produce erude aluminium sullate containing 2000 1b of pure aluminium sullate, 1080 1b o
bauxite and 2510 b of sulfuric acid solution (77.7 pcrcent acid) are uscd.
AlO,+3H,SO,Al,(S0,), +3H,0

- Steelworks activities are important sources of fine particles, which may affect air quality in urban areas close to Fe-Mn-alloy manufacturing plants. In order to identify the identity of the particles, fine particles were sampled inside the chimneys of the plant. Explain briefly the surface analytical techniques in order to identify: (i) Particle composition. (ii) Particle size. (ii) Fe and Mn oxidation states in fine particles.arrow_forward100 90 80 NANO 70 60 CaCl, 50 Pb(NO3)2 40 KCI NaCI 30 8 20 KCIO, 10 Ce,(SO)3 10 20 30 40 50 60 70 80 90 100 Temperature (°C) Solubility (g of salt in 100 g H,O) KNO3arrow_forwardA petroleum gas mixture containing 65% propane, 25% of propylene and 10% of butane (mole percent) is burned with with 40% excess air.

- An Al-4.5wt%Cu alloy has a low-temperature yield stress of 600 MPa due to the precipitation strengthening effect imparted by the equilibrium q phase (Al2Cu) precipitates. Estimate the interparticle spacing and particle size in this alloy. Given: density of α-solid solution 2,700 kg/m3 and density of q phase 4,430 kg/m3. Assume the Cu content in α-solid solution 0.5 wt% and the Cu content in the q phase 54%. Hint: You need to use the Orowan model of particle strengthening and the lever rule among other concepts.arrow_forwardShow all steps please, thanks.arrow_forwardWhich of the following is one of the raw materials used for biodiesel production? short chain alcohols All of these animal fats vegetable oilsarrow_forward
