Abstract: Disclosed herein is a filter apparatus comprising a fluid inlet for a fluid to be filtered in the apparatus; a first fluid outlet for fluid that has been filtered; and one or more barrier filters arranged between the fluid inlet and the first fluid outlet for filtering material from the fluid. In use, the fluid to be filtered is directed from the fluid inlet so as to promote a continuous erosion of material built up on the barrier filter(s). Also disclosed is a method of filtering particles from a particle laden fluid.

Abstract: A method for vaporizing and heating a cryogenic fluid such as a liquefied natural gas, to a desired temperature in the ambient temperature range. The method comprises using an intermediate heat exchange fluid such as propane to heat the liquefied natural gas and to utilize the cold potential of the liquefied natural gas to produce power. The heat exchange fluid is heated by a heat source, such as warm or hot water available from an industrial process. The heat exchange fluid is pressurized and heated to form a heat exchange vapor. The heat exchange vapor is split into multiple streams that exchange heat with the cryogenic fluid in series fashion so that the cryogenic fluid is vaporized and heated to the desired temperature in stages using a common heat exchange fluid and heat source.

Abstract: A heat transfer apparatus (20) and method comprises first (R2/D2) and second (R1/D1) heat transfer units. A heat exchanger (30) has a first portion (32) thereof arranged between the first and second units, and a second portion (34) that is thermally connected to the first portion and not arranged between the first and second units. Each heat transfer unit comprises one or more modules (10), and each module comprises a chamber having a first part (12) which contains a first gas adsorbent material and a second part (14) which contains a second gas adsorbent material. These parts are connected (16) so as to allow gaseous communication therebetween whilst being relatively thermally isolated from each other. In the method: (i) a relatively hot fluid is passed through the heat exchanger second portion (34) whereby the thermal connection to the first portion (32) causes heat to be transferred to the first portion (32); (ii) a relatively cooler first working fluid (RF1) is passed through the second unit (R1) and around the module first parts (12) therein, then through the heat exchanger first portion (32) to be heated up by the heat transferred thereto in step (i), then through the first unit (R2) and around the module first parts (12) therein, to heat those parts and cause gas adsorbed on the first material to desorb and flow to the module second parts (14) in the first unit (D2) to adsorb onto the second material, the first working fluid then exiting the first unit (R2); (iii) the flow of the first working fluid is ceased and another relatively cooler second working fluid (RF2) is passed through the first unit (R2) and around the module first parts (12) therein to cool those parts and cause gas adsorbed on the second material to desorb and flow back to the module first parts (12) in the first unit (R2) and adsorb back onto the first material; (iv) whilst the second working fluid (RF2) is passed through the first unit (R2) and to cause said desorption in step (iii), a first feed fluid (DF2) is passed through the first unit (D2) and around the module second parts (14) therein, whereby the desorption of gas from the second material causes the first feed fluid (DF2) to be cooled, which cooled fluid can then exit the first unit (D2).

Abstract: A method, apparatus and system for transferring heat is disclosed using a first gas adsorbent material, and a second gas adsorbent material that is relatively thermally isolated from but in continuous gas communication with the first material. In a first step the first material is heated so as to desorb a gas adsorbed onto the first material whereby the gas passes to and is adsorbed onto the second material. In a second step the first material is cooled in a manner so that the gas is desorbed from the second material and passes therefrom to be re-adsorbed onto the first adsorbent material. When the gas is desorbed from the second material, the second material is cooled thereby. In this way a hot gas stream can be used to cool another gas stream.

Abstract: A process and apparatus is provided for reducing the heating value of imported LNG by removing natural gas liquid products while condensing boil-off gas. The LNG is pumped from a storage container and is then heated by cross exchange to a dew point temperature. A portion of this heated LNG is sent out to be vaporized while the remaining portion is further heated by cross exchange with demethanizer overhead vapors and is then sent as feed to the demethanizer. NGL is recovered at the bottom of the demethanizer, and the overhead vapors are mixed with boil off gas coming from the LNG storage container. These mixed vapors are condensed by cross exchanging with the LNG feed portion and then pumped to pipeline pressure and sent to the gas pipeline through the vaporizers.
