Deccan Fine Chemicals Interview Questions, Process, and Tips

Mechanical seals are devices that help prevent leakage between two surfaces in relative motion.

• Mechanical seals are commonly used in pumps, compressors, and other rotating equipment to prevent leakage of fluids.

• They consist of two main parts - a stationary element and a rotating element, which are held together by tension to create a seal.

• The seal faces are typically made of materials like carbon, ceramic, or tungsten ...read more

The cost of bearing parts can vary depending on the type, size, and quality of the bearing.

• Bearing parts can range from a few dollars to hundreds of dollars, depending on the specific requirements.

• Factors such as material, size, precision, and brand can all impact the cost of bearing parts.

• For example, a standard ball bearing for a small appliance may cost around $5, while a high-precision ceramic bearing for a special...read more

Predictive maintenance involves using data and analytics to predict when equipment failure may occur, allowing for timely maintenance to prevent breakdowns.

• Uses data and analytics to predict when equipment failure may occur

• Helps in scheduling maintenance activities before breakdowns occur

• Reduces downtime and increases equipment reliability

• Examples include vibration analysis, oil analysis, and thermography

ISO 28721-1.2019 is a code used for establishing a framework for implementing reliability-centered maintenance (RCM) in engineering.

• ISO 28721-1.2019 provides guidelines for developing maintenance strategies based on reliability-centered maintenance principles.

• It helps in identifying the most effective maintenance tasks to ensure equipment reliability and safety.

• The code outlines the process of analyzing potential failu...read more

Number of theoretical plates can be calculated using the plate theory or the distillation column design equation.

• The plate theory method involves using the equilibrium data for the components being separated and the operating conditions of the column.

• The distillation column design equation method involves using the height equivalent to a theoretical plate (HETP) and the total number of plates in the column.

• Example: For...read more

I am a fresher with no prior experience in the field.

• I recently graduated with a degree in Chemistry and am eager to apply my knowledge in a professional setting.

• While I may not have direct experience in production chemistry, I have completed relevant coursework and projects during my studies.

• I am a quick learner and am confident in my ability to adapt to new challenges and responsibilities.

Refrigeration system is a mechanical system that removes heat from a space to lower its temperature.

• Refrigeration systems use a refrigerant to absorb and release heat.

• The basic components of a refrigeration system include a compressor, condenser, expansion valve, and evaporator.

• Examples of refrigeration systems include air conditioning units, refrigerators, and freezers.

Maintaining parameters of an RO plant involves regular monitoring, calibration, and cleaning to ensure optimal performance.

• Regularly monitor key parameters such as flow rate, pressure, and TDS levels to ensure they are within acceptable ranges.

• Calibrate sensors and instruments periodically to maintain accuracy in measurement.

• Perform routine maintenance tasks such as cleaning filters, membranes, and pumps to prevent clo...read more
