  • Patent number: 10787614
    Abstract: A process is presented to treat a process stream containing a hydrocarbon (oil and/or gas) and hydrogen sulfide with a liquid treatment solution containing a sulfur dye catalyst. The process stream can be within a pipeline, wellbore, subsea pipeline or a wellhead that contains hydrogen sulfide where the liquid treatment solution is injected at a predetermined point to define a scavenger zone such that the sulfur dye catalyst in the liquid treatment solution causes the sulfide from the hydrogen sulfide to react with the catalyst. The hydrocarbon component is separated substantially free of the hydrogen sulfide from a spent treatment solution containing spent sulfur dye catalyst which can then be fed to an oxidation vessel where it is contacted with an oxygen containing gas causing the sulfide to oxidize to thiosulfate and converting the spent sulfur dye catalyst to regenerated sulfur dye catalyst.

  • Patent number: 10702794
    Abstract: A distillation system having a plurality of chambers, an input conduit connected to each chamber to deliver an aqueous fluid to each chamber; a pressure reducing valve connected to the input conduit; a waste output conduit connected to a waste collection compartment of each chamber; and condensate output conduit connected to a condensate collection compartment of each chamber. An evaporation wall of each chamber is constructed to maintain an evaporation surface temperature that is greater than a condensation surface temperature of a condensation wall of each chamber. The aqueous fluid forms a fluid coating, which moves down the evaporation wall. A saturation pressure differential is created as water from the aqueous fluid evaporates from the evaporation wall and condenses on the condensation wall forming an aqueous condensate, which moves down the condensation wall and is collected as an aqueous distillate in the condensate collecting compartment.

  • Patent number: 10683461
    Abstract: Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.
