20090094894 | Method and Apparatus for Producing a Hydrogen-Containing Gas - A process and apparatus for producing a hydrogen-containing gas in a reformer where a furnace, which is independent of the reformer, heats the effluent from a prereformer prior to reacting the prereformer effluent in the reformer. The prereformer effluent may be heated in a heat exchange tube in the furnace where the heat exchange tube is positioned in the furnace to preclude direct radiation from any flames in the furnace thereby preventing local overheating of the heat exchange tube and preventing carbon formation in the heat exchange tube. Fuel and oxidant gas may be introduced into the furnace with significant excess oxidant gas, having a stoichiometric ratio of 1.8 to 2.8 for controlling the temperature of the heat exchange tube. | 04-16-2009 |
20090134172 | Vessels With Personnel Access Provisions - Embodiments of vessels include personnel access provisions having welded or otherwise permanent connections that substantially reduce the potential for leakage into or out of the vessels by way of the personnel access provisions. | 05-28-2009 |
20110247979 | Process for Separating Components of a Multi-Component Feed Stream - Provided is a process and apparatus for separating a multi-component feed stream wherein a porous separator is used to effectively create, via permeation and phase change, at least three fractions of differing compositions. | 10-13-2011 |
20120125128 | SYSTEM FOR PERFORMING INSPECTIONS, REPAIRS, AND/OR OTHER OPERATIONS WITHIN VESSELS - A system is provided to facilitate inspections, repairs, and other operations within vessels without human entry into the vessels, and without introducing contaminants that could reduce the purity of materials held in the vessels below predetermined minimum levels. | 05-24-2012 |
20130167584 | HEAT EXCHANGER PERFORATED FINS - A plate fin heat exchanger comprises a folded fin sheet comprising fins wherein the fin sheet comprises a plurality of perforations, such plurality of perforations are positioned on the fin sheet in parallel rows when such fin sheet is in an unfolded state, such parallel rows of perforations on the fin sheet comprise a first spacing between the parallel rows of perforations (S | 07-04-2013 |
20140013946 | SHIELDING IN A SEPARATION COLUMN - A liquid distributor and method for distribution of a liquid in a mass transfer column, the distributor includes at least one riser comprising at least one riser wall, the at least one riser wall extends from a first surface of the distributor in a first direction of the mass transfer column; at least one shield, the at least one shield extends from a second surface of the distributor opposite the first surface and extending in a second direction opposite the first direction; and at least one liquid distribution aperture extending from the first surface of the distributor through the second surface of the distributor, the at least one shield has a length extending in the second direction such that a gap is created between the at least one shield and a packing, the height of the gap between the shield and the packing is about 10 mm to 75 mm. | 01-16-2014 |
20140262732 | ONSITE ULTRA HIGH PURITY CHEMICALS OR GAS PURIFICATION - An onsite purification plant/system to delivery high and ultra high purity product, such as, process chemicals, industrial and specialty gases to manufacturing processes within the onsite plant turndown ratio from 0% to 100% while preserving the predetermined purity of the supplied substances within a predefined specification range is provided. Preserving liquid/vapor ratio in at least one of the purification means/units ensuring that product purity range stays unchanged is achieved by redirecting the product back into the onsite purification plant/system. | 09-18-2014 |
20150352485 | Liquid Distributor in a Separation Column - A distributor for distribution of a liquid in a mass transfer column and method for distribution, including a first riser, a first plurality of liquid distribution apertures positioned adjacent to and at a first distance from a first edge of the first riser; a second plurality of liquid distribution apertures positioned adjacent to and at a second distance from a second edge of the first riser; a second riser; a third plurality of liquid distribution apertures positioned adjacent to and at a third distance from a first edge of the second riser; and a fourth plurality of liquid distribution apertures positioned adjacent to and at a fourth distance from a second edge of the second one riser; wherein the second plurality of liquid distribution apertures are adjacent to and at a fifth distance from third plurality of liquid distribution apertures. | 12-10-2015 |
