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.

respected sir,i have been selected in the written examination(CHEMICAL) of IOCL Panipat held on 30 m1rch, So please tell me which type of questions asked in this interview frequently.Can u mail me some questions?

MASS TRANSFER - EXAMPLE 4.1 : A concentric, counter-current heat exchanger is used to cool lubricating oil. Water is used as the coolant. The mass flow rate of oil into the heat exchanger is 0.1 kg / s = FO. For oil, the inlet temperature TIO = 100 degree Celsius and the outlet temperature TOO = 55 degree Celsius. For water, the inlet temperature TIW = 35 degree Celsius and the outlet temperature TOW = 42 degree Celsius. What is the mass flow rate of water in kg / s, FW needed to maintain these operating conditions? Constant for heat capacity of oil is CO = 2131 J /(kg K) and for water is CW = 4178 J /(kg K). Use the equation (FO)(CO)(TIO ?TOO) = (FW)(CW)(TOW ?TIW).

Question 87 - According to Hardy-Weinberg Equation, p x p + 2 x p x q + q x q = 1 where p = dominant allele frequency and q = recessive allele frequency. Let p + q = 1. Fraction of population has 2 copies of the p gene = p x p. Fraction of population has 2 copies of the q gene = q x q. Fraction of population has a copy of p gene and a copy of q gene = 2 x p x q. In a small town, the allele frequency is q = 0.2 for a recessive gene, the delta-32 mutation, that gives human protection from HIV infection. (a) Find the allele frequency a dominant gene, p. (b) What percent of the population has at least a copy of the gene that cause the population either immune to HIV or less susceptible to the disease?
