    Abstract: A reciprocating compressor includes a compressor cylinder defining a cylinder wall, a valve bore formed in the cylinder wall, and a compressor valve assembly arranged in the compressor cylinder. The compressor valve assembly includes a valve liner having a liner body and a liner flange disposed at an end of the liner body. The liner body is disposed in the valve bore. The liner flange is positioned in contact with the compressor cylinder. A valve seat is coupled to an inner surface of the liner body. The valve seat has a seating surface formed at an end of the valve seat. A compressor valve is positioned on the seating surface of the valve seat. A valve cage is positioned on the compressor valve. A valve cover is coupled to the valve cage to apply a bias force to retain the compressor valve on the seating surface of the valve seat.

    Abstract: A platform seal and damper assembly for turbomachinery (100), such as fluidized catalytic cracking (FCC) expanders or gas turbine engines; and methodologies for forming such assembly are provided. An axially-extending groove (160) is arranged on a side (162) of a respective platform. Groove (160) is defined by a radially-outward surface (168) at an underside of the platform and a surface (170) extending with a tangential component (T) toward radially-outward surface (168). A seal and damper member (152) is disposed in groove (160), where the body of seal and damper member has adjoining surfaces (190, 188) configured to respectively engage, in response to a camming action, with the surfaces (168, 170) that define the axially-extending groove. The camming action being effective to produce an interference fit of the seal and damper member (152) with the side of the respective platform (162) and an opposed side (163) of an adjacent platform.

    Abstract: A system and method for producing liquefied natural gas are provided. The method may include compressing a process stream containing natural gas in a compression assembly to produce a compressed process stream. The method may also include removing non-hydrocarbons from the compressed process stream in a separator, and cooling the compressed process stream with a cooling assembly to thereby produce a cooled, compressed process stream containing natural gas in a supercritical state. The method may further include expanding a first portion and a second portion of the natural gas from the cooled, compressed process stream in a first expansion element and a second expansion element to generate a first refrigeration stream and a second refrigeration stream, respectively. The method may further include cooling the natural gas in the cooled, compressed process stream to a supercritical state with the first and second refrigeration streams thereby produce the liquefied natural gas.
