  • Patent number: 10883483
    Abstract: 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.

  • Patent number: 7674878
    Abstract: Disclosed is a method of producing a non-adhering granulate above the glass-transition temperature comprising a polyester material, in which the polyester material is introduced into a cooling water flow as a melt and is separated from the cooling water after passing through a cooling stretch. The dwell time of the polyester material in the cooling stretch is 0.2-5 sec, and the cooling water has a pressure of at least 2 bar along the cooling stretch. For the thus obtained granulate, post-crystallization is not required, at least not in every case. It has been shown that the granulate does not adhere, even without post-crystallization and mechanical movement if no additional external input of energy takes place. Even during heating under pressure, no adhesion could be observed.
