  • Approaches to simulating distillation and absorption

    Distillation of spirits has been practiced since the time of the ancient Greeks who ascribed sacred powers to the liquids that resulted from refining wine using stills such as the one shown in Figure 1. Dionysian cults incorporated these early spirits into religious rituals. Distillation and other phase separation processes have come a long way since then, and so have the ways they’ve been analyzed and computed. Figure 2 shows the progression of models and computational ...

An overlooked advantage The importance ...

  • H2S oxidation system for refinery desulfurization

    The European Union has recently promulgated new directives reducing the amount of residual sulfur in diesel and gasoline. These directives are requiring European refineries to revise both their fuel production processes and their downstream desulfurization strategies. One affected refinery is Irish Refining plc near Whitegate Middleton, Country Cork, Ireland which recently added a new atmospheric pipestill and expanded their existing gas oil hydrofiner. After the changes, the ...

  • H2S oxidation system for water treatment facilities

    A new water treatment facility in the town of Jupiter, Florida, was causing a serious odor problem. H2S removed from the purified water was being released into the atmosphere. Complaints about the odor came from the residences and businesses downwind of the treatment plant. A turnkey LO-CAT® Hydrogen Sulfide Oxidation System designed to process 30,000 CFM of air containing 250 ppm of H2S solved this problem. Due to the scarcity of fresh water available for treatment ...

  • Hydrogen sulfide removal from sour associated gas

    In November of 1999, PT Pertamina (Indonesia’s staterun oil company) installed the LO-CAT® II Hydrogen Sulfide Oxidation Process for their Mudi Field in East Java, Indonesia. The oil production operation at the Mudi field was producing up to 11 MMSCFD of sour associated gas.

  • LO-CAT® II process for chemical plant desulfurization

    KRONOS’ facility in Leverkusen, Germany produces titanium dioxide, the most important material used by the paints and plastics industry for whiteness and opacity. When new German guidelines set maximum emission limits for SO2 in 1989, KRONOS was required to eliminate the COS from the off-gas at their titanium dioxide production facility to meet the new requirements. Complicating this application, the COS removal process that KRONOS needed had to be built in an area with ...

  • LO-CAT® II process for elevated pressure refinery desulfurization

    MOL Hungarian Oil & Gas Co. selected a LO-CAT® II Desulfurization System for operation at its production unit in Szeged, Hungary. The unit was custom-designed for direct treatment of sour associated and process gas streams at elevated operating pressures and relatively high CO2 partial pressures.

  • LO-CAT® II process for H2s oxidation and sulphur recovery

    Lubrizol’s facility in LeHarve, France produces a lube oil additive via a batch reaction that uses elemental sulfur as a reactant and produces H2S as a byproduct. Lubrizol selected Merichem’s LO-CAT® II Hydrogen Sulfide Oxidation Process to sweeten H2S emissions and recover sulfur. The LO-CAT II system was chosen for its ability to handle the process variation in H2S concentration. During the 8-hour batch reaction cycle, H2S concentrations in the effluent gas ...

  • LO-CAT® process as a claus tailgas cleanup unit

    In 1997, Western Gas Resources selected the LO-CAT® process to treat the amine acid gas generated in their Pinnacle Gas Processing plant located in Tennessee Colony, TX. When the facility’s processing demand exceeded the LO-CAT capacity (2 LTPD of sulfur), Western Gas installed another LO-CAT unit having a capacity of 7 LTPD. In the summer of 2000, Western Gas once again forecasted that future processing requirements would dramatically exceed the sulfur removal capacities ...

  • LO-CAT® process for waste water treatment plants

    In 1980, Los Angeles began exploring alternatives to control the H2S concentration in the digester gas produced at the Hyperion Waste Water Treatment Plant (WWTP), which treats nearly 420 MGD, wastewater generating over 475 tons of raw sludge per day. The digester gas H2S concentration had to be controlled so that the SOX emissions from the on-site combustion of the gas could be kept within acceptable regulatory limits, allowing the gas to be burned on-site to generate steam for ...

  • Optimisation of a sulphur recovery unit

    Prior to Suncor’s purchase of the Spirit River facility, little attention was given to the LO-CAT® unit. In general, over injecting chemicals into a LO-CAT unit will not result in operating problems, just higher than required operating costs. Consequently, in remote gas plants such as Spirit River, it is sometimes difficult to convince operators to change operating conditions if the unit is not presenting any operating problems. However, this is not Suncor’s operating ...
