The system is an old one. The building is probably over 100 years old. It is the original facility. Most of the original equipment has been replaced by now.

Some of the system is liquid overfeed. Some of it is using a controlled pressure receiver for liquid feed.

Other areas use what we call pumper drums (liquid draining by gravity into a small vessel. When the vessel fills up with liquid, high pressure gas is used to displace or "pump" the liquid out to the system).

There about 26 screw compressors of various sizes connected to about 4 suction pressure systems. Two stage compression.
