An apparatus and method for enhancing the heat and water recovery from a transport membrane condenser (TMC) includes a non-moving mechanical device inserted into the TMC tubes to increase the heat transfer efficiency via the enhancement of the fluid turbulence and/or surface area. The apparatus and methods may be applied to porous tubes arranged in a spaced array, similar to a conventional shell and tube heat exchanger device. Other configurations of the TMC may be conceived and adapted for use with the described apparatus and method.

Transport membrane condenser using turbulence promoters

A method suitable for treating used oil to remove ash and metal contaminants therefrom with minimum oxidation of the oil, the metal including at least one of the components of iron, lead, copper, zinc, sodium, magnesium, and calcium, to provide a highly purified oil product having less than 10 ppm of at least one of the contaminants and less than 0.15 wt. % of ash content. The method comprises providing a body of oil to be purified and chemically treating the oil to condition ash and metals contained therein to facilitate removal of ash and metal during membrane purification of the oil. A porous inorganic membrane module having a high pressure side and a low pressure side is provided and the chemically treated oil is introduced to the high pressure side of the membrane module to provide an oil permeate on the low pressure side and an ash and metal-rich concentrate on the high pressure side thereby separating ash and metals from the oil to provide the highly purified oil product at an improved level of throughput of the membrane compared to feed oil not chemically treated.

Deashing and demetallization of used oil using a membrane process

Disclosed is a method suitable for treating used oil to remove contaminants including ash and color contaminants therefrom to provide a purified oil product. The method comprises the steps of providing a porous inorganic membrane module having a high pressure side and a low pressure side, and a body of oil to be treated. The oil is introduced to the high pressure side of the membrane module to provide an oil permeate on the low pressure side and an ash rich concentrate on the high pressure side thereby separating ash in the oil from the oil permeate. Thereafter the oil permeate is contacted with an adsorbent to remove one of color and odor from the oil permeate to provide a purified oil product. The spent adsorbent can be regenerated and reused.

Refining of used oils using membrane- and adsorption-based processes

A ceramic fired composite filter media having a uniform pore size, the media consisting essentially of a porous cordierite substrate having a surface having pores of non-uniform diameter, the diameter ranging from &lt;1 to 200 .mu.m; and a layer of porous ceramic oxide having pores having a uniform diameter bonded to the surface of the cordierite substrate, the layer of ceramic oxide comprised of ceramic oxide particles having a particle size sufficiently large to avoid substantial penetration of the pores in the surface of the cordierite.

Inorganic membranes using porous cordierite support

A high temperature ceramic membrane device for separation of fluids at high temperature, the device comprises: (a) a housing having: (i) an entrance for introducing fluids to the housing to be separated, (ii) an exit for removing fluids after being subjected to separation; (b) a plate mounted in one end of the housing, the plate having openings therein; (c) ceramic membrane comprised of porous ceramic tubes having a closed end and an open end, the tubes permeable by a fraction of the fluid to be removed from the fluid as filtrate and impermeable to a second fraction, the open end designed to remove the filtrate from the tube, the tubes mounted in the openings in the plate so that the closed end is projected into the housing and the open end is extended outside the housing for removing the filtrate; (d) a seal for sealing the plate in the housing; (e) insulation provided in the housing, the insulation means located adjacent the plate and surrounding the tubes projecting therethrough, the insulation adapted to insulate the hot fluid in the housing from the plate; and (f) cooling outside the housing adjacent the seal to maintain the seal at a relatively low temperature.
