Abstract (en)
[origin: EP3628867A1] A seal assembly for a reciprocating rod of a reciprocating compressor, a reciprocating compressor with the seal assembly, and a method of operating the reciprocating compressor with the seal assembly to prevent leakage of gas once the compressor has been shut down. The pressure difference between opposite sides of a static seal is kept low during normal operation to reduce wear of the static seal. When the compressor is shut down, a high pressure difference between opposite sides of the static seal assists with sealing.
