Understanding Gas Compression

What is the primary function of a compressor in the process industry?

• To increase the volume of gas

• To decrease the volume of gas while increasing pressure

• To transport liquids

• To cool down gases

How do compressors differ from pumps?

• Compressors and pumps have the same function

• Compressors are used for gases, pumps for liquids

• Compressors increase gas volume, pumps decrease it

• Compressors are used for liquids, pumps for gases

What happens to gas molecules during compression?

• They remain stationary

• They disappear

• They move further apart

• They move closer together

Which of the following is NOT a basic design of compressors?

• Dynamic

• Thermal

• Hydraulic

• Positive displacement

How do dynamic compressors like axial and centrifugal types operate?

• By changing the velocity of a gas and converting energy to pressure

• By decreasing the pressure of the gas

• By increasing the temperature of the gas

• By transporting liquids
