20100191005 | OXYGEN/HYDROCARBON RAPID (HIGH SHEAR) GAS MIXER, PARTICULARLY FOR THE PRODUCTION OF ETHYLENE OXIDE - A gas mixer is disclosed which includes a vessel ( | 07-29-2010 |
20100204495 | HYDROCARBON/OXYGEN INDUSTRIAL GAS MIXER WITH WATER MIST - A hydrocarbon-containing gas is mixed with an oxygen-containing gas in a gas mixer in the presence of a water mist. The water mist surrounds and contacts entrained particles in either the oxygen-containing gas stream or the hydrocarbon-containing gas stream. The water acts to suppress and prevent ignition of the hydrocarbon gas in the mixer by serving as a sink for heat created by energetic collisions between such particles and structures within the gas mixer. The water mist also acts to quench ignition caused by such collisions. The water mist can be introduced into the gas mixer in a number of different configurations, including via nozzles injecting a mist into a hydrocarbon gas manifold or an oxygen gas manifold, nozzles placed within the gas mixer adjacent to ends of the oxygen supply pipes, and nozzles placed coaxially within the oxygen supply pipes in the gas mixer. | 08-12-2010 |
20100204496 | HYDROCARBON/OXYGEN INDUSTRIAL GAS MIXER WITH COARSE WATER DROPLET ENVIRONMENT TO REDUCE IGNITION POTENTIAL - A hydrocarbon-containing gas is mixed with an oxygen gas in a gas mixer in the presence of coarse water droplet environment, e.g., a ‘rainy’ or ‘driving rainstorm’ environment in which the water droplets generally have a size greater than 200 microns SMD. The water droplets surround and contact entrained particles in either the oxygen gas stream or the hydrocarbon-containing gas stream. The water acts to suppress, prevent and quench ignition of the hydrocarbon gas in the mixer which would otherwise be caused by energetic collisions between such particles and structures within the gas mixer. In one configuration the gas mixer includes water pipes having coarse water droplet-producing nozzles at the peripheral end thereof concentrically located within oxygen supply pipes. Additionally, nozzles introduce coarse water droplets into a pipe carrying the hydrocarbon gas and forming a mixing chamber for the hydrocarbon and oxygen gases. | 08-12-2010 |
20100263535 | WET SCRUBBING FOR REMOVING PARTICULATE SOLIDS FROM OXYGEN SUPPLY LINE - A method of mixing an oxygen gas with a hydrocarbon-containing gas includes the steps of wet scrubbing the oxygen gas in a wet scrubber, supplying oxygen gas from the wet scrubber to a gas mixer and mixing the oxygen gas with the hydrocarbon-containing gas in the gas mixer. Wet scrubbers for use in the method may take various forms, including packed-tower, bubble cap, and sparger-type wet scrubbers. The removal of the particulate matter reduces the risk of ignition of the hydrocarbon-containing gas in the gas mixer. The use of a wet scrubber in the oxygen supply line overcomes many problems currently faced with screen and filters, as per current practice. | 10-21-2010 |
20100298493 | METHOD FOR GAS PHASE POLYMERIZATION - Disclosed is a catalyst injection nozzle that comprises an outer tube with an open end, a nozzle tip with a diameter connected to the outer tube open end, an orifice connected to the nozzle tip internal to the outer tube, an internal mixing zone connected to the orifice internal to the outer tube, an inner tube residing within the outer tube further comprising an open end connected to the internal mixing zone, where a steady-state, uniform two-phase flow regime between an atomizing gas and at least one liquid catalyst feed does not form in the internal mixing zone at an atomizing gas to liquid catalyst feed flow ratio of about 0.05 to about 10. | 11-25-2010 |

20140221718 | EXCESS AIR CONTROL FOR CRACKER FURNACE BURNERS - A method for control of the air/fuel ratio of the burner(s) (excess air) of a thermal cracker includes three steps. The thermal cracker has three consecutive zones or portions through which combustion gases pass, a firebox portion, a bridge wall portion and a convection portion The first step is to direct a wavelength modulated beam of near infrared light from two different tunable diode lasers located in the bridge wall portion through combustion gas from the burner to a pair of near infrared light detectors, each positioned to receive the wavelength modulated beam of near infrared light from a different one of the two tunable diode lasers to generate a detector signal. The second step is to analyze the detector signals for spectroscopic absorption at wavelengths characteristic of oxygen and carbon monoxide to determine their respective concentrations in the combustion gas. The third step is to adjust the air/fuel ratio of the burner(s) (excess air) in response to the concentrations of oxygen and carbon monoxide of the second step. | 08-07-2014 |
20140355373 | MIXER FOR CONTINUOUS FLOW REACTOR - A mixer for a continuous flow reactor and methods for forming the mixer and the operation thereof. The mixer allows for segmentation of a primary reactant flow through a plurality of ports into many smaller flows that are injected as jets into a secondary reactant flow in channels of the mixer. The channel has a constant width dimension to enhance even flow distribution and local turbulence of the primary and secondary reactant flows. The constant width dimension of the channel and the size and number of the ports of the mixer can be configured to ensure the primary reactant flow injected into the channel directly impinges on a surface of the channel that is opposite the injection point at normal operating conditions. | 12-04-2014 |
