ESSAR OILCGPA Cut Off: 6.0

1. Technical Round: Comprising of 170 MCQ questions, it was divided into 4 sections:-i. Quantitative Reasoning- 40ques

ii. Technical questions- 50quesiii. Analytical Reasoning- 40quesiv. English- 40ques

Quant reasoning questions were apparently easy (as per d reviews given) English was the simplest of all as it had questions related to PREPOSITIONS!! Few of the questions asked in the quiz:

Total reflux ratio and its effect on distillation column Distillation column asked in detail Constant Numbers- Prandlt, Reynold, peclet, Nusselt, Mach No etc Heat Exchangers, shell side, pressure drop effects on heat exchanger venturi meter bernoulli's equation, its applications, significance of the equation Application of continuity equation Dryers (around 4-5 different questions were asked) Liquid-Liquid extraction & Solid-liquid extraction (arnd 4-5ques) In which type of packing is max surface area available? Humidification, Relative Humidity, dew point Conveyors, which type is used for sand/ asphalt rittinger's law, types of grinding Pumps: centrifugal & reciprocating pump Size reduction techniques Pumps, Blowers, Valves and Compressors: different types available, its applications,

which type of a pump is more relevant in what situation..

Most of the technical questions were based on subjects MTO(25), HTO(5), FFO(10) and MO(10)

2. Group Discussion: Obama’s visit to India helping the Indian Economy Entire batch of 17 people were asked to speak on the same topic Around 20mins were given to prepare..

3. Personal Interview: around 20mins/person. Few general questions apart from the questions based on the training/project

Distillation Column Types of trays, which tray used in laminar/ turbulent flow. Type of flow used in packed & tray column What is Cross-current, counter flow Questions about the equilibrium curve, determining the no.of theoretical trays from the curve

Heat Exchanger Design, what are the characteristics of fluids to be used? Which fluid goes in shell and which in tube? Fouling factor, what causes fouling factor

Significance of LMTD method Significance of laminar/ turbulent flow Pumps- centrifugal pump, any hands on experience operating a Pump? Valves and blowers types and usage. What is an orifice meter? What’s its usage? Working of an Air Conditioner Difference between Gas and vapor Dew point, flash point Why is sulfur removed from every process? (** Major Pollutant, deactivates catalyst) Activity of an catalyst Joule-Thompson effect Types of reboiler, tray you would use on the situation given by them Affinity law Thermodynamics 2nd law How to operate a control valve? On what principle does a pressure cooker works? Le chatelier principle Components of crude oil (*as it was an oil company) How would you separate the crude oil components Major components of LPG Bernoulli’s equation, its applications

HR questions:

Describe yourself.. why did u take chemical engineering Are you willing to be in the refinery as the Jamnagar city is 45km away.. Any problems of homesickness What’s the work of chemical engineer in a refinery Are u willing to work in shifts? working hours Will you be a field operator?

Seniors’ advice:

Know your training report & project very well.. Play safe, don’t mention anything about the report that you don’t know because they grill you

with questions based on what you have said! Go through http://www.indiabix.com/ for aptitude, technical round questions Distillation Column, Pumps, Blowers, Valves, compressors: know at least these few topics

thoroughly
