  • Patent number: 7815700
    Abstract: A device, system and method of mixing two fluids are described herein. A gaseous first fluid is distributed through a distribution zone to a mixing zone by a bundle of pipes parallel to an axis inside which the first fluid is uniformly distributed. A second fluid is uniformly distributed outside the pipes in the distribution zone. The mixing zone is separated from the distribution zone by a pipe-plate supporting the pipes. The pipe-plate has slits or openings to uniformly discharge the second fluid in an axial flow direction into the mixing zone. The pipes extend beyond the pipe-plate into the mixing zone to partialize an outlet flow of the first fluid. In one aspect, the pipes have different lengths to partialize the outlet flow. In another aspect, a terminal portion of the pipes partializes the outlet flow axially, radially, transversally or a combination thereof in the mixing zone.

  • Patent number: 6793699
    Abstract: The invention provides an apparatus for online and on-site tracer generation for tagging natural gas stored in underground storage fields wherein feedstock is drawn from a feedstock source. The feedstock undergoes initial analysis to determine hydrocarbons levels. The feedstock then undergoes reaction to produce tracers such as ethylene, propylene, acetylene hydrogen and carbon monoxide. The feedstock is then analyzed to determine post reaction tracer concentration. The feedstock including generated tracers is then introduced back into the feedstock stream. Tracer levels in the pre-reaction or initial analysis of feedstock are compared with tracer levels in the post-reaction feedstock and the rate of flow of feedstock through the system is adjusted to achieve a predetermined level of tracer concentration. The level of tracer concentration will then be used to identify the particular natural gas charge in a storage field.

  • Patent number: 6299657
    Abstract: In the reaction process, at least two educts A, B are divided by a system, assigned to each of them, of slit-like microchannels 1a, 1b into spatially separate fluid lamellae, which then emerge into a common mixing and reaction space 4. The fluid lamellae here have a thickness <1,000 &mgr;m, preferably <100 &mgr;m, at a width thickness ratio of at least 10. It is essential here that educts A, B can emerge as thin fluid lamellae 6a, 6b into the mixing/reaction space 4, each fluid lamella 6a of an educt A being led into the mixing/reaction space 4 in the immediate vicinity of a fluid lamella 6b of another educt B. The adjacent fluid lamellae 6a, 6b then subsequently mix by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially compared with conventional reactors. In the case of rapid chemical reactions, the formation of undesirable by-products or secondary products is largely prevented in this manner.
