The steam compressor recovers low-pressure steam leftover from various processes and pressurizes it by mixing it with high-pressure motive steam. The result is low/mid-pressure steam that can be reused in another process.

As high-pressure and low-pressure steam mix, the pressure reducing valve responds to fluctuations in secondary pressure and adjusts the valve opening accordingly, regulating the steam flow.

Low pressure steam generated by applications such as power generation can also be recovered and reused.
