    摘要： An ultra low NOx burner for process heating is provided which includes a fluid based flame stabilizer which provides a fuel-lean flame at an equivalence ratio in the range of phi=0.05 to phi=0.3 and fuel staging lances surrounding the flame stabilizer in circular, flat, or load shaping profiles, each lance comprising a pipe having a staging nozzle at a firing end thereof, each lance having at least one hole for staging fuel injection, and each hole having a radial divergence angle and an axial divergence angle. The at least one hole and the divergence angles provide circular, flat or load shaping flame pattern. The burner provides NOx emissions of less than 9 ppmv at near stoichiometry combustion conditions.

    摘要： A symmetric device for stabilization of a flame includes a primary oxidant pipe and a fuel pipe. The fuel pipe is internal to the primary oxidant pipe creating a primary oxidant conduit. A secondary oxidant pipe is internal to the fuel pipe creating a fuel conduit. A primary oxidant source supplies oxidant to the primary oxidant conduit. A fuel source supplies fuel to the fuel conduit. A secondary oxidant source supplies oxidant to the secondary oxidant pipe. The first oxidant velocity is greater than the second oxidant velocity and the fuel velocity is less than the second oxidant velocity. The primary oxidant pipe end extends past the fuel pipe forward end and the fuel pipe forward end extends past the secondary oxidant pipe end. A mismatch in velocity between fuel and oxidant generates a large scale vortex. An asymmetric embodiment is also provided.

    摘要： The present invention provides a method for recovering a natural gas contaminated with high levels of carbon dioxide. A gas containing methane and carbon dioxide is extracted from a reservoir containing natural gas, where carbon dioxide comprises greater than 40 vol. % of the extracted gas. The extracted gas is scrubbed with a wash effective to produce a washed extracted gas containing less carbon dioxide than the extracted gas and at least 20 vol. % carbon dioxide. The washed extracted gas is oxidized with an oxygen containing gas in the presence of a partial oxidation catalyst to produce an oxidation product gas containing hydrogen, carbon monoxide, and carbon dioxide. The oxidation product gas is then utilized to produce a liquid methanol product.
