LO-CAT - the green solution to sulfur recovery

The LO-CAT process, available exclusively from Merichem, is a patented liquid redox system that uses a proprietary chelated iron solution to convert H2S to innocuous, elemental sulfur. It does not use any toxic chemicals and does not produce any hazardous waste byproducts. The environmentally safe catalyst is continuously regenerated in the process. The LO-CAT technology is applicable to all types of gas streams including air, natural gas, CO2, amine acid gas,biogas, landll ...

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 other ...

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. Recycled process gas and associated gases are collected from the oil fields around the plant and transported via a mixed-phase pipeline, followed by separation in a bank of ...

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 ...

Turnkey systems from specification to installation can be developed to meet stringent schedules. We also offer technical service and support. LO-CAT systems provide ...

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 ...

Meet emission challenges with reliable Claus tail gas unit performance

Meet emission directives while improving your sulfur management. In today’s oil and gas industry, maximizing sulfur recovery from off-gases is extremely important. Regulations get tighter, forcing operators to constantly optimize the efficiency of their sulfur management units. Adding a tail gas treating plant to your Claus unit will enable you to meet the most stringent emission targets for final sulfur removal from the off-gases. The effluent from a Claus plant is the ...
