Natural gas liquefaction system employing an open methane cycle wherein the liquefied natural gas is flashed immediately upstream of the liquefied natural gas storage tank and boil off vapors from the tank are returned to the open methane cycle.

Enhanced methane flash system for natural gas liquefaction

Natural gas liquefaction system employing an enhanced nitrogen removal system capable of removing nitrogen from a relatively warm natural gas stream.

LNG system with warm nitrogen rejection

Natural gas liquefaction system having an optimum configuration of mechanical drivers and compressors. A heat recovery system can be employed with the liquefaction system to enhance thermal efficiency. A unique start-up system can also be employed.

Driver and compressor system for natural gas liquefaction

Natural gas liquefaction system employing electric motors as compressor drivers. A combination of motors and steam turbines can be powered by a cogeneration plant and employed as drivers.

Motor driven compressor system for natural gas liquefaction

Natural gas liquefaction system employing a zeolite adsorbent for removing nitrogen from pretreated natural gas.

Natural gas liquefaction with improved nitrogen removal

A peripheral frame member holds flexible sheets of material tightly over a central open area. A channel around the back of the frame is adapted to receive a flexible strip member having a longitudinally extending bifurcated projection engageable within the length of the channel. When a thin sheet of flexible material is placed over the back of the frame and the strip member pressed down so that the projection fits tightly within the channel, the material is locked in place and stretched taut across the central open area. The frame is preferably rectangular with channels along each side and a plurality of longitudinal strips engage respective sides. The device provides a simplified structure which is particularly useful for holding and displaying fabrics for embroidery and needlecraft projects.
