Title: Natural gas liquefaction
Inventor: WILKINSON JOHN D
IPC: F25J1/00
Filed: 2009-02-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a process for liquefying natural gas while producing a liquid stream mainly containing hydrocarbons heavier than methane by using energy quite less than in a conventional process.  <P>SOLUTION: In this process, as shown in Fig.3, a natural gas stream to be liquefied is partially cooled, expanded into intermediate pressure, and supplied to a distillation column 19. A bottom product from the distillation column 19 preferably contains most part of all hydrocarbon heavier than methane which may reduce the purity of the liquefied natural gas. A residual gas stream from the distillation column is compressed into high intermediate pressure, cooled to be condensed under pressure, and expanded into low pressure to form a liquefied natural gas stream.  <P>COPYRIGHT: (C)2009,JPO&INPIT

The tip part of each element wire of the elastic member 31 comes into contact, in a round cut state, with a polishing pad 20 to dress the polishing pad 20. The diameter of the tip part of each element wire of the elastic member 31 is small to reduce the cutting width of the polishing pad 20. The element wires of the elastic member 31 are bundled with a wire bundling band 35 to enhance the rigidity of the elastic member 31 and thus realize the application of a high pressure to the tip part having a small diameter in the element wires. Therefore, the tip part of the elastic member 31 can give an effective incision depth to the polishing pad 20.  <P>COPYRIGHT: (C)2010,JPO&INPIT
