A gas mixture consisting of 10% ethylene gas (C2H4) and 90% CO2 by mol is combusted with 50% excess air via the following unbalanced reaction: C2H4 (g) + O2 (g) à CO2 (g) + H2O (g) Air for the reaction is brought in from outdoors and cooled through a chiller to remove any humidity. The combustion product gas is pressurized so that all water vapor is condensed into liquid, which then combines with the water from the air chiller and exits through a separate H2O stream. a) Draw the process flow diagram. b) If the outdoor air has a dry bulb temperature of 30°C and 30% relative humidity (RH), how many mol of water leave the system (in the combined H2O exit stream) per mol of ethylene combusted? c) What is the molar volume (in L/mol) of the water-free combustion gas if it is pressurized to 150 atm at 20°C? CO2: Tc = 31.2°C, Pc = 72.8atm O2: Tc = -118.6°C, Pc = 49.8atm N2: Tc = -147°C, Pc = 33.5atm

One of the major concerns related to climate change is sea level rise. The Intergovernmental Panel on Climate Change (IPCC) has estimated that we are likely going to see sea level rise of around three feet by 2100. However, these estimates have come under heavy criticism in recent years as being far too conservative. Why are the IPCC estimates so conservative (i.e. what information does the IPCC not include in its models or estimates of sea level rise)? According to the VICE documentary piece that profiles Dr. Eric Rignot, how much would global sea levels rise if the West Antarctic Ice Sheet were to melt? (5%) How is Eric Rignot and his research team able to use radar and lasers to determine the thickness and melt rates of West Antarctic ice shelves?

To achieve efficient process operations, it is essential that appropriate process equipment is selected. For air separation based on cryogenic distillation, the selection of the wrong type of heat exchanger (HEX) can lead to sub-optimum plant performance, operability issues, and equipment failure. Briefly discuss the different types of heat exchangers available, and the suitability of the HEX for air separation units (ASUs) based on cryogenic distillation.

Hydrofluoric acid (HF) is produced by reaction with a massive flow rate of 6000 kg / h and 99% pure calcium fluoride (CaF2) sulfuric acid. The reaction takes place with 97% conversion. The reaction equation is given below: CaF2 (solid) + H2SO4 (g) → CaSO4 (solid) + 2HF (g) Solid by-product, unreacted solid reagents and impurities are taken from the bottom of the reactor. The gas phase HF and unreacted H2SO4 are taken from the reactor and sent to the bottom of an absorption column. Aqueous acid solution containing 40% acid (HF + H2SO4) by weight is taken from the bottom of the column by absorbing 99% of HF and 99% of H2SO4 with the water sent over the column. 1% of the acid vapors emerge from the top of the column without absorption (Ca: 40; F: 19; H: 1,; S: 32; O: 16) a) Draw the block flow chart. b) Establish mass balance around each device and over the entire system.

A filtration component consists of a rectangular channel having dimensions H = 10 cm, W = 50 cm, and L = 100 cm, containing carbon pellets of diameter 5 mm, is modelled using the Ergun equation. Develop the pressure drop versus mass flowrate (for ?̇ in the range of 1 – 50 kg/s) characteristic for the following porosities (due to packing arrangement): ? = 0.5, 0.7, and 0.9. The fluid properties may be taken to be ρ = 1000 kg/m3 , μ = 1.0 × 10-3 Pa⸱s. What is the pressure drop when ?̇ = 50 kg/s? Is it better to operate three filters in series or in parallel? Why?
