20140322125 | RECOVERY OF SULFUR TRIOXIDE HEAT OF ABSORPTION - A contact process for manufacture of sulfuric acid is disclosed in which the vapor phase heat of formation of sulfuric acid in the sulfur trioxide conversion gas and the heat of absorption of SO | 10-30-2014 |
20140322118 | REGENERATIVE RECOVERY OF CONTAMINANTS FROM EFFLUENT GASES - A contaminant gas is removed from a feed gas in two absorption and stripping circuits operated in tandem. The gas is first passed through a rich gas absorber producing a rich absorption liquor from which contaminant gas is stripped in a rich liquor stripper. A lean gas exiting the rich gas absorber is passed through a lean gas absorber, producing a lean absorption liquor from which contaminant gas is stripper in a lean liquor stripper. Regenerated absorption media exiting the respective strippers are recirculated to the respective absorbers. | 10-30-2014 |
20140096683 | FIBER BED ASSEMBLY INCLUDING A RE-ENTRAINMENT CONTROL DEVICE FOR A FIBER BED MIST ELIMINATOR - A fiber bed assembly used to remove aerosols and/or wetted soluble solids from a moving gas stream includes a fiber bed support and a fiber bed supported by the fiber bed support so that the gas stream passes through the fiber bed moving from an upstream space to a downstream space with respect to the fiber bed. A re-entrainment control device is located within a downstream space defined by the fiber bed so that at least a portion of the gas stream passes through the re-entrainment control device. The re-entrainment control device is shaped to change the direction of the average flow path of the gas stream as the gas stream passes through the re-entrainment control device so as to cause aerosols and/or wettable solids contained therein to be separated from the gas stream by inertial force. A re-entrainment control device and method of use are also disclosed. | 04-10-2014 |
20140079624 | ENERGY RECOVERY IN MANUFACTURE OF SULFURIC ACID - This invention relates to the recovery of energy in the manufacture of sulfuric acid, and more particularly to enhanced recovery of energy from the absorption of wet SO | 03-20-2014 |
20130315807 | REGENERATIVE RECOVERY OF CONTAMINANTS FROM EFFLUENT GASES - This invention relates to processes for the selective removal of contaminants from effluent gases. More particularly, various embodiments of the present invention relate to selective removal and recovery of sulfur dioxide from effluent gases in a regenerative sulfur dioxide absorption/desorption process that achieves favorable energy efficiency. Energy is recovered from a wet stripper overhead gas stream produced in the desorption cycle by indirect transfer of heat from the stripper gas to a cooling medium and used to generate steam for use in stripping contaminants from the absorption liquor. The absorption zone may optionally be cooled to enhance the capacity of the absorption medium for absorption of a contaminant gas, thereby lowering the volume of absorption medium and contaminant-enriched absorption liquor that must be pumped, handled, heated and cooled in the absorption/desorption cycle. | 11-28-2013 |
20130115159 | ENERGY RECOVERY IN MANUFACTURE OF SULFURIC ACID - This invention relates to the recovery of energy in the manufacture of sulfuric acid, and more particularly to enhanced recovery of energy from the absorption of wet SO | 05-09-2013 |
20120107209 | REGENERATIVE RECOVERY OF SULFUR DIOXIDE FROM EFFLUENT GASES - This invention relates to processes for selective removal of contaminants from effluent gases. A sulfur dioxide absorption/desorption process for selective removal and recovery of sulfur dioxide from effluent gases utilizes a buffered aqueous absorption solution comprising weak inorganic or organic acids or salts thereof, to selectively absorb sulfur dioxide from the effluent gas. Absorbed sulfur dioxide is subsequently stripped to regenerate the absorption solution and produce a sulfur dioxide-enriched gas. A process for simultaneous removal of sulfur dioxide and nitrogen oxides (NO | 05-03-2012 |
20110056381 | FIBER BED ASSEMBLY FOR A FIBER BED MIST ELIMINATOR - A fiber assembly for a forward-flow fiber bed mist eliminator used to remove aerosols from a moving gas stream. The assembly incorporates an improved drainage system for draining aerosols from the fiber bed without the need for a conventional seal-leg. | 03-10-2011 |
20110056378 | FIBER BED ASSEMBLY FOR A FIBER BED MIST ELIMINATOR - A fiber assembly for a forward-flow fiber bed mist eliminator used to remove aerosols from a moving gas stream. The assembly incorporates an improved drainage system for draining aerosols from the fiber bed without the need for a conventional seal-leg. | 03-10-2011 |
20100244439 | EXPANSION JOINT FOR PIPE SYSTEM - An expansion joint for a pipe system includes a deformable section interconnecting first and second pipe sections. A first mount is secured to the first pipe section in a passageway of the first pipe. A second mount is secured to the second pipe section in a passageway of the second pipe. A flexible tension member, extending through the deformable section, tethers the first and second mounts to each other. | 09-30-2010 |
20080314009 | FIBER COLLECTING MEDIA STRIP FOR A MIST ELIMINATOR - A fiber bed mist eliminator has a fiber bed which is formed of a composite fiber bed collecting media strip including a collection layer which is not subjected to needle punching. The fiber bed can be made very thin while retaining high efficiency in removing small particles of aerosol from a gas stream passing through the fiber bed. The fiber bed collecting media strip lends itself to be applied to the mist eliminator by spirally wrapping the element onto the mist eliminator. The fiber bed collecting media strip can overlap itself to seal at the locations where the fiber element overlaps itself. The fiber bed collecting media strip can be provided to the field in different formats for use in making a mist eliminator fiber bed. | 12-25-2008 |
