Process Shift Incharge Interview Questions and Answers

Carbon paste consumption in electrodes can be calculated by considering the weight of the paste used per electrode.

• Calculate the weight of carbon paste used per electrode by measuring the initial and final weight of the electrode before and after use.

• Divide the total weight of carbon paste used by the number of electrodes to get the average consumption per electrode.

• Keep track of the consumption over time to monitor trends and make adjustments as needed.

Interesterification of oil is a process that involves rearranging the fatty acids in oil to modify its physical and chemical properties.

• Interesterification is used to improve the melting point, texture, and stability of oils.

• The process involves mixing a blend of oils with a catalyst, such as sodium methoxide or enzymes.

• The mixture is heated and agitated to promote the rearrangement of fatty acids.

• The reaction is monitored for the desired level of interesterification, which c...read more

The overall SOP of hydrogenation of oil involves several steps to convert unsaturated fats into saturated fats.

• Hydrogenation is a chemical process used to convert unsaturated fats into saturated fats.

• The process involves the addition of hydrogen gas to the oil in the presence of a catalyst.

• The oil is heated to a specific temperature and pressure to facilitate the reaction.

• The hydrogenation process can be carried out in batch reactors or continuous flow reactors.

• The reaction i...read more

Density is mass per unit volume of a substance.

• Density = Mass / Volume

• Units of density are typically g/cm^3 or kg/m^3

• Density can be used to identify substances based on their mass and volume

• Example: The density of water is approximately 1 g/cm^3
