  • Publication number: 20160060190
    Abstract: A process of producing a sweetened liquid hydrocarbon stream. In order to prevent the forming of acid species in a sweetening zone, a oxygenate removal zone is disposed upstream of the sweetening zone. The oxygenate removal zone may comprise a water wash or an adsorbent zone, including a regenerable adsorbent. The sweetened stream is formed from a least a portion of liquid natural gas stream which may be scrubbed free of hydrogen sulfide and dehydrated before passing to the oxygenate removal zone.

  • Publication number: 20140338869
    Abstract: A process for heating a cold stream with a hot stream is described. At least one of the cold inlet or outlet, the hot inlet or outlet, the cold inlet or outlet header, the hot inlet or outlet header, and the plurality of plates is made of one of two stainless steel alloys. One alloy has higher molybdenum content with copper for improved corrosion resistance and is resistant to chloride pitting, chloride SCC, and PTA SCC. The other alloy has significantly higher tensile and yield strength, which will reduce the susceptibility of the plate bundle to thermal stress damage.

  • Patent number: 8323416
    Abstract: One exemplary embodiment can be a process for removing one or more scale deposits formed on a surface. The process can include contacting the surface with a composition for a period of time sufficient to remove the scale deposits that comprise coke or metal sulfides or mixtures thereof. Generally, the composition includes an effective amount of an organic acid and/or a salt thereof, and an effective amount of an oxidizing agent.

  • Patent number: 8128887
    Abstract: A coating applied to at least a portion of the surfaces of reactors, reactor internals, other reactor components, and/or heater tubes is provided in order to minimize the formation of metal catalyzed coke in hydrocarbon conversion processes operating at temperatures at about 350° C. (662° F.) or greater and in reducing environments. These coatings may comprise Nickel coatings or complexes thereof, such as Ni—Al, Ni—Cr/Cr carbide, as well as aluminum painted coatings that are applied in a reduction cure process (e.g., application temperatures of about 600° C. (1112° F.)). Additionally, where H2S is necessary for the process, such as to minimize thermal cracking, the coatings also reduce corrosion of base metal due to sulfidation attack and eliminate the requirement of continuous replacement of reactor internals and other components.

  • Patent number: 7345214
    Abstract: A catalyst for opening naphthenic rings has been developed. The catalyst comprises ruthenium and platinum as the active catalytic metals and a modifier with cerium being a preferred modifier. At least 50% of the platinum and ruthenium components are present as particles wherein more ruthenium is present on the surface of the particles than in the center. All of these components are dispersed on a metal oxide support such as aluminas. A ring opening process using the catalyst is also described.
