Styrene is made by dehydrogenation of ethyl benzene, which is formed by alkylation of benzene with ethylene. Propose target yields for the alkylation and dehydrogenation steps if the forecasted prices per metric ton are styrene $800, ethylene $800, and benzene $500.
Note: Structures for the compounds in Problems 2.3, 2.8, and 2.9 can be found in the Merck Index, but are not required to solve the problems.
Discuss the applicability of each model - Does it differ based on the interactions you would expect for each model. Can you conclude that one of the models is 'better' than the others from your graphs/analysis in Problems 3.1-2?
In terms of heat treatment and the development of microstructure, what are two major limitations of the iron-iron carbide phase diagram?
Calculate the volume of 0.25 M NaI that would be needed to precipitate all the g2+ion from 45 mL of a 0.10 M Hg(NO3)2 solution according to the following reaction:
Estimate the number-average molecular weight that is required to give a tensile strength of195MPa.
A completely enclosed stirred-tank heating process is used to beat an incoming stream whose flow rate varies. The heating rate from this coil and the volume are both constant.(a) Develop a mathematical model (differential and algebraic equations) tha..
When heavy oils are cracked in a catalytic or thermal cracking process, lighter hydrocarbon compounds are formed. Most cracking processes on heavy oil feeds form products with carbon numbers ranging from two to greater than twenty.
question 1a discuss in details on five types of health effects related to exposure to hazardous substances encountered
Calculate the work done in breaking up a drop of petrol of volume 1 cm3 into 109 drops. Surface tension of petrol is given as 26 dynes/cm.
Into a barrel containing 33.2 bbl (US) of water containing 0.0012 mol/L of a blue dye you pour V2 yd3 of water containing 8.91 M of the dye. The final concentration of the dye in the barrel is 7.91 mol/m3 after it's well-mixed. What is V2 is yd^3?
A distillation column separates benzene from toluene using a control scheme similar to that shown in Figure (a). Make a practice HAZOP study of the plant section and add any instrumentation that is needed to develop the full P and I diagram.
Name the microstructural products of eutectoid iron-carbon alloy (0.76 wt% C) specimens that are first completely transformed to austenite, then cooled to room temperature at the following rates:
1. A newly constructed power plant proposes to burn coal with a sulfur content of (a) 1.8 and (b) 2.4 percent by weight. If the plant is to meet the new source review performance standard (see attached CFR new source regulation), what percent of SO 2..
