Provided in some embodiments is a gas compression system that includes a gas compressor having a drive shaft, an impeller drive shaft magnetically coupled to the drive shaft, and a shroud disposed between the drive shaft and the impeller drive shaft. In other embodiments provided is method that includes magnetically coupling a first drive shaft to a second drive shaft, receiving a rotational torque at the first drive shaft, transmitting the rotational torque from the first drive shaft to the second drive shaft via the magnetic coupling, and rotating a gas compressor impeller coupled to the second drive shaft.

Gas compressor magnetic coupler

A system, in certain embodiments, includes a seal assembly having a seal body. The seal body includes an inlet buffer port and an outlet eduction port. The inlet buffer port is configured to receive a compressed buffer gas, such as shop air, which is injected into the inlet buffer port. The compressed buffer gas blocks the flow of a compressed process gas, such as land fill gas, by opposing the flow of the compressed process gas through the seal assembly. Both the compressed buffer gas and the compressed process gas may be expelled through the outlet eduction port.
