Hindalco Industries Shift Incharge Engineer Interview Questions and Answers

Power factor is a measure of how efficiently electrical power is being used. To maintain a power factor of 0.80, various measures can be taken.

• Power factor is the ratio of real power (kW) to apparent power (kVA).

• To improve power factor, reactive power should be reduced.

• Installing power factor correction capacitors can help improve power factor.

• Regular maintenance of electrical equipment can prevent power factor degrada...read more

C3 value is a measure of coke formation in a refinery. It should be less than 0.1 wt%.

• C3 value is the weight percentage of coke formed during thermal cracking of petroleum products.

• It is an important parameter to monitor in a refinery as high C3 value can lead to fouling of equipment and reduced efficiency.

• The ideal C3 value is less than 0.1 wt%.

• C3 value can be reduced by optimizing the cracking process and using addit...read more

Reductions and flux are chemical reactions used in metallurgy to extract metals from their ores.

• Reduction is the process of removing oxygen from a metal oxide to obtain the metal.

• Flux is a substance that is added to the ore to lower its melting point and to remove impurities.

• The reaction formula for reduction is: Metal oxide + Carbon → Metal + Carbon dioxide

• The reaction formula for flux is: Impurities + Flux → Slag

• Exam...read more
