Explain what are the major raw materials used to produce propylene. For the most common raw material, calculate how much petroleum will be needed to produce that raw material on an annual basis.

) Separation processes are essential in chemical engineering. A typical chemical plant is a chemical reactor surrounded by separators where raw materials are pre purified using relevant tools and techniques and then fed to the chemical reactor; unreacted feed is separated from the reaction products and recycled to the reactor. Sometimes products and by products must be further separated and purified before they can be sold.  (a) You are required to describe how the following unit operations can be used for separation in the chemical process industry. (i) Chromatography (ii) Ion Exchange (iii) Stripping

The feed stream to a reactor contains ethylene 16%, oxygen 9%, nitrogen 31%, and hydrogen chloride. If the ethylene flow is 5000 kg/h, calculate the individual com- ponent flows and the total stream flow. All percentages are by weight.

please answer 9 properly!! and answer 10 too but make sure 9 is answered good and correct thanks.

The Leading Crop for Biodiesel Production in terms of liter of oil per hectare is: Cottonseed Olive Coconut None of these

If Equimolar mixture of A and B is mixed, 200  kgmol/hr of water (component C) is used to extract B  into aqueous phase. The product flow rates is 350  kgmol/hr. Find the Feed flowrate and the product  composition.

Calculate the % yield for each crude solid based on the total amount of starting mixture. Starting mass = .804g Mass of crude p-dimethoxybenzene = .401g Mass of benzoic acid = .396g

2. A 60 wt% Pb-40wt% Mg alloy is rapidly quench. The final microstructure consists of an a phase (with mass fraction of 0.42) and Mg₂Pb phase (with mass fraction of 0.58). What is the approximate temperature from which this alloy was quenched? Temperature (°C) 700 600 500 400 300 200 100 0 0 (Mg) R 20 a + L L a + Mg₂Pb 40 60 Composition (wt% Pb) L MB₂Pb M Mg₂Pb 80 L + Mg₂Pb B B B+ Mg₂Pb 100 (Pb)

2. Carbon nanotubes (CNT) are among the most versatile building blocks in nanotechnology. These unique pure carbon materials resemble rolled-up sheets of graphite with diameters of several nanometers and lengths up to several micrometers. They are stronger than steel, have higher thermal conductivities than most known materials, and have electrical conductivities like that of copper but with higher current- carrying capacity. Molecular transistors and biosensors are among their many applications. While most carbon nanotube research has been based on laboratory-scale synthesis, commercial applications involve large industrial-scale processes. In one such process, carbon monoxide saturated with an organo-metallic compound (iron penta- carbonyl) is decomposed at high temperature and pressure to form CNT, amorphous carbon, and CO2. Each "molecule" of CNT contains roughly 3000 carbon atoms. The reactions by which such molecules are formed are: Decomposition of Fe(CO)s to form iron, which…

Can you reword this for me to have a better understanding: Plastic items like bottles and bags are made from polyethylene. Ethylene Oxide / Ethylene Glycol – becomes polyester for textile, and antifreeze for airplane engines and wings. Ethylene Dichloride – this, in turn, becomes a vinyl product used in PVC (polyvinyl chloride) pipes, siding, medical devices, and clothing. Styrene – synthetic rubber found in tires, as well as foam insulation.”
