Project Engineer Instrumentation Interview Questions and Answers

Oil & gas is highly inflammable due to its low flash point and high volatility.

• Oil & gas have low flash points, which means they can ignite at relatively low temperatures.

• Oil & gas are highly volatile, meaning they evaporate quickly and form flammable vapors.

• The presence of hydrocarbons in oil & gas makes them highly combustible.

• Oil & gas can easily mix with air to form explosive mixtures.

• The high energy content in oil & gas contributes to their flammability.

• Examples of highl...read more

Low pressure and low voltage are used in petrochemical plants for safety and efficiency reasons.

• Low pressure is used to prevent leaks and accidents in the handling of volatile substances like oil and gas.

• Low voltage current is used to minimize the risk of electrical hazards and ensure worker safety.

• Low pressure and low voltage systems are more energy-efficient and cost-effective in petrochemical operations.

• Examples of low pressure instruments used in petrochemical plants incl...read more
