The pressure of a gas is important for its transportation, processing and storage.
Gas arriving at a processing plant, or already in the plant, may not be at the correct
Pressure for subsequent operation. If the pressure of the gas is too high it can be
reduced easily. If the pressure of the gas is too low a Compressor must be used to
increase it. A Reciprocating Compressor is classified as a positive displacement machine. That is,
a solid object displaces gas from inside the machine and in so doing compresses the gas
to increase its pressure, this is done by one or more pistons moving in one or more cylinders.
Centrifugal Compressors on the other hand, compress gas by moving the
gas and increasing its speed within the compressor. The basic principles of operation for Steam and Gas Turbines are also covered in this course.
