http://en.wikipedia.org/wiki/Asphaltene


Answer

•Composition of crude oil


3. ID the above equipment used to pump clean/sterile fluids


Answer

• Peristaltic pump


4. Identify


Answer

•Mendeleev's Periodic table

•Note that his arrangement presents the periods vertically, and the groups horizontally.


• 5. In 2007, a controversy broke as the ICC banned the “Kookaburra Kahuna” cricket bat which was used by several high-profile players including Ricky Ponting and Michael Hussey .

• The reason was that a thin layer of a particular material was bonded to the back of the entire bat to strengthen the blade and assist in shock absorption.

What material was used?


Answer

Carbon fibre or Graphite fibre

Ricky Ponting scored an incredible 1,795 runsin 12 months using this bat.


6. Identify this equipment used in extraction of crude oil


AnswerChristmas tree

•The primary function of a Christmas tree is to control the flow, usually oil or gas, out of the well.


•7. If the single-pass conversion (once-through conversion) of A to B is 40%, then what is the recycle rate R (mol/hr)?


• 150 mol/hr

• Since X=0.4, then 100/0.4 should be the feed which gives us 250 mol/hr. So 100 mol/hr is the fresh feed then 150 mol/hr will be the recycle rate R=150 mol/hr.

Answer


•8. In 1981, the government of the United States of America initiated a joint project between the research division at MIT and the Department of Energy, specifically to create Advanced Systems for Process engineering. As a result of the project, the company X was born.

•On October 1, 2013, Antonio Pietri became the President & CEO of the company after the previous CEO Mark Fusco retired.

•Which company am I talking about?


Answer:

•AspenTech (Advanced System for Process ENgineering Technology)

‘X’ is the one of the most critical components required for drilling a well. The primary functions of ‘X’ are,

1. To lift cuttings of the wellbore to surface so thatthe hole is cleaned properly

2. To exert adequate hydrostatic pressure on theformation so that the entry of formation fluidsinto wellbore is prevented

3. To lubricate the drill bit while drilling process

X is a thixotropic fluid

13. What is ‘X’?


AnswerDRILLING FLUID or MUD


14. Google doodle to commemorate the 270th birth anniversary of which notable scientist ?


Alessandro Volta

Answer


•15. Which rule has been used to plot this graph?

Note :The various lines indicate different concentrations


Answer

• Dühring’s rule

•For strong solution, the boiling point of the solution is a linear function of the boiling point of pure water at the same pressure.


GROUP I GROUP II

P. Centrifugal pump 1. used in chemical installations to pump high viscosity fluids

Q. Twin Screw pump 2. used to transport fluids by the conversion of rotational kinetic energy to the hydrodynamic energy of the fluid flow

R. Gear pump 3. used to pump high-pressure viscous fluids

S. three-spindle screw pump 4. used when pumping conditions contain high gas volume fractions and fluctuating inlet conditions

16. Match


Answer

• P-2

• Q-4

• R-1

• S-3


• 17. Identify the flow meter:

• Principle: Fluid passing through a vibrating U shaped tube produces small elastic deformations. From the magnitude of the elastic deformations, the mass flow rate may be calculated.

gif


Answer• Coriolis meters


• X make sure that the pump is always primed and makes sure that the fluid flows in only one direction

• X is created with a larger flow area than the actual pipe size to make sure that there is less head loss.

• X consists of a strainer that prevents picking up

large debris that could clog or jam the opening.

18. These are particular functions of a component(X) in a piping system


Answer

• Foot valve


• X is the place where the first oil well in Asia was drilled. The first refinery was started here as early as 1901.

• Today, X boasts two energy wonders of the world—a hundred-year-old oil field that is still operational andthe world's oldest operating oil refinery, which produces in excess of its capacity.

• Story goes that X gets its name, as the Canadian Engineer, Mr W L Lake shouted "Dig Boy, Dig", at his men as they watched elephants emerging out of the dense forest with oil stains on their feet

19. Id the place X


Answer


20. • X is a chemical element with atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal.

• Y is a chemical element with atomic number 35. It is a fuming red-brown liquid at room temperature, corrosive and toxic.•Historically, the compound XY was used to purify radium in a process of fractional crystallization devised by Marie Curie.

•X and Y together is featured in the opening credits of a famous TV show.

Answer

• Dhirubhai Ambani

• Dhirubhai Ambani set up his first business "Majin" in partnership with his second cousin to import polyester yarn and export spices to Yemen.


23. Reasons explaining which phenomenon ?

• The main reason has been found to be the formation of an even layer of crystalline iron hydrogen phosphate on its surface.

• The mild climate of the place is responsible as the relative humidity at 70% for significant periods of time in the year.

• Several investigators have stressed the importance of the material used as relatively pure composition of the iron is used with presence of Phosphorus (P) and absence of Sulphur/Magnesium.


Answer

• THE CORROSION RESISTANCE OF DELHI IRON PILLAR

• 25. A phenomenon called‘Tears of wine’ manifests as a ring of clear liquid, near the top of a glass of wine, from which droplets continuously form and drop back into the wine.

• It is most readily observed in a wine which has a high alcohol content.

•What is the cause of this phenomenon?


Answer • Surface tension gradient

• A case of Gibbs-Marangoni effect - the flow of liquid caused by surface tension gradients.

The effect is a consequence

of the fact that alcohol has

a lower surface tension

than water.
