IOCL Placement Paper Technical - Other new Delhi-24 Mar 2008
I have given iocl exam as diploma in chemical engineering .In technical section some question i have remembered are:1.the thermal conductivity of a gas:i) increases with increasing temp.2.relation between stanton no. peclet no. and nusselt no.i)nussult no. / peclet no. = stanton no.3.which of following heat exchangers is used for chilling oil to be dewaxed?i)double puipe heat exchanger4. the purpose of steam trap isi) to remove condensate and inert gases5: steam economy of triple effect evaporator isi)>16: Duhring rule is useful in solving problems oni) evaporation7:dry ice isi) solid carbon dioxide8:glass isi) a super cooled liquid9:temporary hardness of water may be removed by addingi) calcium hydroxide10: carbohydrates are the organic compound ofi) carbon hydrogen oxygen11:vinyl chloride has the formulai) CH2=CHCL12:the temp. of water cooled in cooling tawer isi) always less than the wet bulb temp. of entering airand 2-3 question was on kinematic viscosity like dimension of kinematic viscosity and 2-3 was on reflux ratio from distillation, and one question was on pump on n.p.s.h. don't remember that question exactly but mostly question of that paper was from the book of objective type q&a in chemical engineering by Dr Ram Prasad.
