Centrifugal compressor control

Q: What are the basics of two-stage centrifugal compressor control?

A: For steam turbine or variable speed electric motors, speed is the basic control method. For a constant speed drive, as a fixed speed electric motor, throttling is the basic method of control.

Several questions concerning compressors

Question one. What is a compressor surge? How does it occur, and how can it be prevented?

Question two. What are sweet and sour oils?

Question three. What is critical speed?

Compressor efficiency
If I have four air reciprocating compressors in a series, what would happen to the efficiency if I placed them in parallel to each other?

Compressed air applications
I was curious to know where can we use high pressure process air. I am trying to understand the applications of compressed air above 150 psig. The only applications that comes to mind is the manufacture of pet bottles. Are there any other applications or industries where compressed air above 150 psig is used?

Centrifugal compressor surging phenomenon
Please describe the surging phenomenon with a centrifugal compressor. We use a MHI compressor that is turbine driven. How should we take action?

Air receiver size for reciprocating air compressor
How can we determine the size/capacity of an air receiver for a reciprocating air compressor? What are the factors that affect the capacity of receiver?
