What is the difference between turbine and compressor?

Turbines are used as propulsion engines of aircraft, helicopters, compressors and generators.

The generators were powered by ALLISON turbines (3 MW), SIMENS GT ( MW) powered by generators and SOLAR (5 MW)

gas compressors were driven.

we have solar gas compressors are driven by gas turbine and the compressed gas from the discharge of these gas compressors is used to gas lift wells. 

Currently, the gas wells are being converted from gas lift to be operated by ESP

Then, gas compressors will not longer used

My questionis: is it possible to dismantle the gas compressor from the gas turbine and utilize the existing gas turbine to produce a n electic power and if yes, is it costely or not   

The compressor provides energy to a cool gas...it is designed to compress air or any gas. It is like swiming, you propel yourself by push a flow of water

A turbine extracts hot energy from gasses produced from combustion. When the water turns rough in a river or in a beach, the stream of water drags you by.

 

Basically turbine is a work producing device while compresor is a work consuming device. In a turbine a high pressure fluid enters and leaves as a low pressure fluid. Here pressue energy is converted into kinetic energy.

In a compressor, the fluid (gas) enters in low pressure and exits in high pressure state. This pressure ratio is achieved by providing external work input. Hence compressor is a work consuming device.

A turbine converts chemical energy to mechanical it is used for power generation by being connected to generators or powering compressors to produce a jet of air in airplanes.

Compressors on the other hand take mechanical energy by a motor to compress fluids (air or gas) to achieve desired pressure and characteristics

compressor is compressor gas as per system requirements

turbine convert Fluid energy to mechanical energy

Compressor Compresses air/gases to reducing volume by application of energy 

• Turbine

A turbine is a device that uses shaft work to drive an electric generator.

Turbines can be found in steam, gas, and hydrostatic power plants.

The heat transfer in and out of a turbine can typically be considered negligible as well as the potential energy unless otherwise stated

Though there is a change in kinetic energy of the gas going through the turbine.

As a mechanical note, liquid can damage the blades of a turbine, so it is better to keep the fluid in a gas state as much as possible.

• Compressor

A compressor, on the other hand, does the opposite of what a turbine does.

Instead of using shaft work to create power, a required amount of shaft work is required to run the compressor.

However, like a turbine the heat transfer and the potential energy can be considered negligible unless otherwise stated.

Also, fluid velocity is negligible for a compressor which means the kinetic energy can also be considered negligible.

turbine is a prime mover  use for   convert the   thermal energy into mechanical energy. 

compressor add energy in fluid /gas for which purpose to displace  of gas from one place to another place or reaction 

Turbine is a prime mover, it contain blade which rotates when pressurized steam , water hits its blade and mechanical energy converted into electrical energy with the help of generator. And compressor is used to compress the steam or water so that pressure increase. It can be done easily demonstrating using a narrow pipe, when water enter from larger end and goes to smaller end we can feel the pressure difference.
