Answer / ranjit

it depends whether u r a fresher or having some work
experience.if u r a fresher u must be very clear with the
basics of chemical engineering in ff,mt and ht with little
knowledge on petrochemical process.for more information u
can contact on my id...ranjitb4u2k@yahoo.co.in
i m already placed with refinery.

Answer / avinash

Exactly depends on whether you have experience or fresher.If you are a fresher,then they might start from your basics like charles law,boyle's law,avogadro's law and then go on to what you did in your BE project (very important).I was asked "Define a refinery in terms of a chemical engineer?" I was also asked questions regarding IBP,FBP,API Gravity,Cetane Number,specifications for petrol and diesel in different Euro norms,Difference between hydrocracking,hydrotreating and hydro-desulfurization,how will you design a heat exchanger and then cut point for different distillates and lots other questions. But after you gain experience for a few years,they will not ask all these.What they will ask is that what things you did worthwhile while you were in the previous company,what initiatives you took on your own etc.

Question 49 - According to rules of thumb in chemical process design, consider the use of an expander for reducing the pressure of a gas when more than 20 horsepowers can be recovered. The theoretical adiabatic horsepower (THp) for expanding a gas could be estimated from the equation : THp = Q [ Ti / (8130a) ] [ 1 - (Po / Pi) ^ a ] where 3 ^ 3 is 3 power 3 or 27, Q is volumetric flowrate in standard cubic feet per minute, Ti is inlet temperature in degree Rankine, a = (k - 1) / k where k = Cp / Cv, Po and Pi are reference and systemic pressures respectively. (a) Assume Cp / Cv = 1.4, Po = 14.7 psia, (temperature in degree Rankine) = [ (temperature in degree Celsius) + 273.15 ] (9 / 5), nitrogen gas at Pi = 90 psia and 25 degree Celsius flowing at Q = 230 standard cubic feet per minute is to be vented to the atmosphere. According to rules of thumb, should an expander or a valve be used? (b) Find the outlet temperature To by using the equation To = Ti (Po / Pi) ^ a.

QUANTUM CHEMISTRY AND CHEMICAL ENGINEERING - EXAMPLE 31.4 : In a rigid rotor model in quantum chemistry, the moment of inertia I is given by an Equation E as I = Ma x La x La + Mc x Lc x Lc = m x L x L, where m = (Ma x Mc) / (Ma + Mc) and L = La + Lc, m is the reduced mass, Ma is the mass of a, Mc is the mass of c, La is the radius of a from point O, Lc is the radius of c from point O. Prove by simplest method that Equation E is wrong.
