Re: ONGC Chemical Engineering Exam Syllabus

Here I am providing the exam pattern and syllabus of ONGC Chemical Engineering Exam

Eligible applicants will be required to appear for Written test (Objective Type) constituting three sections -
General Awareness,
Concerned subject, and an

Total duration will be of 03 hours.
Verbal/ Non-verbal Reasoning,
Numerical Ability
Aptitude test
comprising of Reading Comprehension,
Quantitative Aptitude,
Data Interpretation

ONGC Chemical Engineering Exam Paper

1- film coefficient of heat transfer- thermal conductivity/film thickness

2- Petroleum coke is made by Residue by- Pyrolysis

3- correction factor for single tube pass-

4- Oxygen demand- COD>BOD

5- A unit step response to transfer func G=1/(s^2+1)-

6- phase lag- 45 deg

7- chemical used in the test of COD- both options KMnO4 and K2Cr2O7 are rite but K2Cr2O7 mostly preferd over KMnO4.

8-By product of wet process for the production of phosphoric acid- Gypsum

9- for Pr>1 conduction will be within viscous sublayer

10- mass transfer and momentum transfer- Sherwood No. Sh

11- Three unequal sized mixed flow reactor in series with volume 5L, 10L, 15L is arranged as-

12-fluid energy mill- attrition

13-for black body absorptivity and emmisivity equivalence-

14- view factor for concentric spheres of radius R2 for smaller sphere and R1 for larger one is- R2/(R1+R2)

15- ficks law for- molecular diffusion

16- superheated steam is not used for heating in HE due to- less heat transfer film coefficient

17- limiting reactant question-

18- rxn between acetylene and chlorine- vinyl chloride is formed

19- (synthesis gas)- CO+H2

20- evaporator arrangement for viscous fluid- backward feed

21- for cold and viscous- mixed feed

22- pump NPSH is- Head + Vapour pressure of Liquid.

23- cooling tower question- all options were correct

24- wet bulb temperature- lies between dew point and dry bulb temperature i.e. 40*C-60*C

25- 1/c0 vs t curve straight line for- 2nd order reaction

26- laminar flow question- there is flow in streamline no flow across.

27- After absorption ammonia is removed from- Distillation

28- on incresing temperature relative humidity- increases

29- aniline point for- aromatic content of diesel

30- catalyst used in the production of Nitric acid 97%- platinum/rhodium

31- Heat engine efficiency and temp diff 60*C now given find the temp of heat source and sink- 325& 265*C

32- For 1st order rxn in porus catalyst thiele modulus is 10 then effectiveness factor is- 0.1

33- For gas phase rxn 2A-->B, feed consists 80 mole% A and 20 mole% inerts. if the conversion of A at the reactor exit is 50% then Ca/Ca0 at reactor outlet- 5/8

34- A pulse tracer is introduced in an ideal CSTR at time t=0,time taken for the exit conc. of the tracer to reach of of its initial value- 0.693*t

35- A batch adiabatic reactor with an initial temp. of 373K is used for the rxn A-->B. Assume heat of rxn is -1kJ/mol at 373K and heat capacity of both A and B is constant 50J/mol.K. The temp rise for the conversion of 0.5- 10*C

36- Moles of Air used for complete combustion of C3H8-

37- Molar composition of a gas is 10% H2, 10% O2, 30% CO2, and balance H2O. Now 50% H2O condenses then the final mole % of H2 in the gas on dry basis- 20%

38- A pitot tube indicates 5cm of water when it is used for measuring velocity of air. velocity of air in m/s is- 28.2

39- real gas approaches ideal behavior when- pressure<1 and Temp>1

40- Rxn between Gleceride and Aldehyde- Transesterification

41- An alkaline solution is used to reduce the conc. of CO2 in a stream from 10% to 0.1% by absorption with irreversible chemical rxn. The overall NTU based on gas phase is- 4.605

42- Multiple effect evaporator has capacity to process 4000kg of solid caustic soda per day when it is concentrating from 10% to 35% water. The water evaporated in kg/day is- 27,500

43- Heat is transfered through three layer of different thermal conductivity- 20.27 kW/hr.m2

44- Optimum reflux ratio depends on- Costing of Column

45- Converting Black Liquor to White Liquor- drying, adding caustic with dilution

Re: ONGC Chemical Engineering Exam Syllabus

ONGC provides same syllabus for all branch students. The placement paper of ONGC is based on general awareness and reasoning.

Here the syllabus of ONGC all engineering Level Syllabus

For the Subject Discipline syllabus, candidates should have to study the whole subject (Electrical, Electronics, Mechanical, Chemistry, Bioler, Materials management, production, Accounts, Personnel & Administration, Heavy equipment) important topics for the examination.

General Awareness syllabus

For the General Awareness or General Knowledge questions, read the news paper daily for current affairs and current events details, Important Days, Famous persons birthdays, political news, geography, major events, social issues etc.

Reasoning Syllabus

Topics of Verbal and Non verbal like coding decoding, alphabet series, number series, blood relations, analogy, decision making etc

ONGC exam paper pattern:

Type of Question Number of Objective Type Questions
Subject Discipline 90
General Awareness 30
Reasoning 30
Grand Total 150

Duration of Written Test 3 Hrs
There will be no negative marking.
Each objective type question carries one mark
