  • Claus unit treatment of shutdown tail gas
    Patent number: 10188988
    Abstract: The process for configuring or reconfiguring a sulfur removal plant having a plurality of Claus units that is greater than the number of downstream tail gas treating units (TGTUs) allows for the regeneration of one of the Claus units without shutting down any of the downstream TGTUs or the other Claus units. Specifically, the regeneration tail gas can be diverted to the reaction furnace of an in-service Claus unit, thereby allowing excess oxygen to be used to regenerate the Claus unit more efficiently, and without exceeding environmental SO2 emission requirements.

  • Staged complementary PSA system for low energy fractionation of mixed fluid
    Patent number: 10143960
    Abstract: A staged complementary pressure swing adsorption system and method for low energy fractionation of a mixed fluid. Two beds in a four-column PSA system are selective for component A, and another two columns are selective for component B. The cycle creates an intermittent A and B product, using the purge effluent from the complementary product fed at an intermediate pressure. This intermittent product is used as purge gas for low-pressure purged elsewhere in the cycle using appropriate storage tanks. The use of an intermediate pressure in this cycle enables continuous production of purified component A and B without the use of compressors. Columns may also be configured to enable pressure to equalize between complementary columns.

  • Quartz crystal characterization of fractions derived from cracked streams
    Patent number: 10139387
    Abstract: Methods are provided for characterizing the stability of a distillate fraction using a quartz crystal microbalance apparatus, such as a distillate fraction derived at least in part from a pre-refined crude oil. A sample can be aged for an aging period in a quartz crystal microbalance apparatus, and a frequency value for the sample in the quartz crystal microbalance apparatus can be determined before and after the aging period to determine a frequency difference. This frequency difference can be correlated directly with the ability of a jet fuel fraction to satisfy a stability test standard, such as a jet fuel breakpoint stability. The methods can also include using a temperature profile during characterization that can reduce or minimize operator error during the characterization.

  • Polarity-enhanced ductile polymer fibers for concrete micro-reinforcement
    Patent number: 10131579
    Abstract: Cementitious mixtures, such as concrete, can be reinforced by adding one or more ductile but strong synthetic copolymer microfibers to the mixture. The synthetic copolymer microfibers improve local energy dissipation and bear load, taking the driving force for crack propagation away from the crack tip and thus reinforcing the cementitious mixture against the propagation of microscopic cracks. The resulting mixtures have an improved balance of strength properties.
