206 results about "Ninetieth percentile" patented technology

The 90th percentile is a measure of statistical distribution, not unlike the median. The median is the middle value. The median is the value for which 50% of the values were bigger, and 50% smaller. The 90th percentile tells you the value for which 90% of the data points are smaller and 10% are bigger.

System for recovering glycol from glycol/brine streams

A system for recovering glycol from glycol and brine mixtures produced from oil or natural gas wells that combines energy efficiency with a capability for handling salt and other solids contained in the mixture. The system comprises three effect evaporator systems in series. Each effect evaporator system comprises an evaporator, a separator vessel, product pumps, and a solids removal system.The process utilizes the system to remove salt and other solids as well as excess water leaving a glycol stream that can be reused as a hydrate inhibitor. The process begins by preheating a glycol / brine stream comprising approximately fifty percent (50%) glycol. The stream is then subjected to three evaporation cycles. The first evaporation cycle comprises introducing the preheated stream into a suppressed boiling point evaporator where the stream is heated under a constant pressure. The stream pressure is then dropped to cause a portion of the water contained in the stream to vaporize or flash. The flashing stream is then introduced into a separator vessel where the water vapor is separated from the remaining liquid stream. The water vapor is removed from the separator and condensed. The remaining liquid glycol / brine stream is then pumped from the separator vessel through a solids removal system where precipitated salts and solids are removed. These steps are repeated two additional times. Each time the remaining liquid stream becomes more concentrated with glycol until the finished product is approximately ninety percent (90%) glycol.

Facer beam barrier system

This invention expands Nelson's Sub-Rigid Fast-Form Barrier System that it was originally a part of. The system disclosed herein is simple to manufacture and simple to use and promises wide commercial application as the labor costs for concrete construction become increasingly prohibitive. The extraordinary absence of nails, screws, bolts, welds or any other fastening device allows these barriers to compete with many conventional barrier systems and any concrete form system on the market today. The invention addresses eccentric beam loading where barriers must be economically fabricated to withstand liquid concrete pressure in a sub-rigid manner. While providing a lightweight beam with heavy weight strength it is also a goal of this invention to provide a form system that is self-contained, meaning that all fasteners to construct the barrier, ties that hold form barriers together, staging needed to erect the barriers, bolts used to plumb the barriers and brackets available to hoist the barriers are all integral parts of this invention. Another goal disclosed herein are barriers for concrete formwork that are made up of ninety percent standard building products found in any locality in the world. This barrier invention offers rapid erection time that can be accomplished by unskilled labor and result in a quality construction.

Platinum and Platinum Based Alloy Nanotubes as Electrocatalysts for Fuel Cells

Electrocatalyst durability has been recently recognized as one of the most important issues that have to be addressed before the commercialization of the proton exchange membrane fuel cells (PEMFCs). The present invention is directed to a new class of cathode catalysts based on supportless platinum nanotubes (PtNTs) and platinum alloy nanotubes, for example, platinum-palladium nanotubes (PtPdNTs), that have remarkable durability and high catalytic activity. Due to their unique combination of dimensions at multiple length scales, the platinum nanotubes of the present invention can provide high platinum surface area due to their nanometer-sized wall thickness, and have the potential to eliminate or alleviate most of the degradation pathways of the commercial carbon supported platinum catalyst (Pt/C) and unsupported platinum-black (PtB) as a result of their micrometer-sized length. The platinum nanotube catalysts of the present invention asymptotically approach a maximum of about twenty percent platinum surface area loss in durability test, while the commercial PtB and Pt/C catalysts lose about fifty-one percent and ninety percent of their initial surface area, respectively. Moreover, the PtNT and PtPdNT catalysts of the present invention show higher mass activity and much higher specific activity than commercial Pt/C and PtB catalysts.

Waste gas purification method and equipment

InactiveCN101530708APlay the role of recycling and reducing emissionsLess investmentUsing liquid separation agentWater bathsPurification methods
The invention relates to a waste gas purification method and equipment, especially to a industrial waste gas dedusting, dewatering and desulfurization method and equipment. Technical scheme of the invention includes steps: spraying water to waste gas to fully mix and separate gas and water and make dust-containing sewage to flow downwards; making the waste gas to flow upwards to enter a helical channel, carrying out deceleration and temperature lowering for the waste gas so that contained water is adhered to wall of the helical channel to naturally flow downwards; and discharging the purified flue gas. The invention has advantages that compared with common industrial waste gas dedusting, dehydrating and desulfurization equipment, the invention saves investment by two thirds, has small resistance and high purification efficiency, does not generate secondary pollution, has simple structure and can substitute wet type dedusting facility such as common impact wet type filtration deduster and water bath deduster, water collection efficiency of the helical channel can reach 90%, and waste gas after secondary purification reaches national standard and is discharged into atmosphere, so that the invention has environmental protection and waste water circulation, namely emission reduction, functions.
