KDSOx™

Cost-effective SOx reduction solution for full-combustion FCC units. Reducing SOx emissions has become increasingly challenging in many parts of the world. Depending on the location, SOx emission limits are defined at the refinery level as bubble limits; at the individual emissions source; or, in some cases, by the concentrations in the atmosphere in the vicinity. In light of these challenges, many refineries have successfully used SOx additives for reducing overall sulfur ...

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 ...

LO-CAT® process for costeffective desulfurization of gas streams

The LO-CAT® II process provides cost effective H2S removal for all types of gas streams in many different industries. The LO-CAT and LO-CAT II processes have achieved H2S removal efficiencies of 99.9+% in many different applications and industries. These applications include natural gas production, oil refining, biogas, landfill gas, coke oven gas, geothermal steam power production, CO2 production for beverage use, lube oil production, and many others. These applications range ...

LO-CAT® process for sulphur recovery / odor control

The LO-CAT® Hydrogen Sulfide Oxidation System provides economical H2S removal to solve odor problems quickly and effectively. LO-CAT achieves H2S removal efficiencies exceeding 98%. The system also eliminates costly once-through chemicals, offers unique mobile bed contacting material, and reduces operating costs. Turnkey systems from specification to installation can be developed to meet stringent schedules. We also offer technical service and support. LO-CAT systems provide ...

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 ...

Quantifying FCC gasoline sulfur reduction

Refiners everywhere have to comply with government-mandated fuel specifications, in particular dramatically lower gasoline sulfur levels. While post-treating remains an option, the associated octane loss creates additional constraints for refiners, particularly those who are hydrogen limited. Regardless of whether your refinery is post-treatment or hydrogen constrained, a gasoline sulfur reduction additive such as Albemarle’s RESOLVE line can reduce reliance on post-treating ...

SOxMASTER-2™

Optimal SOx reduction without rare earth for partial- and full-burn units. SOx reduction additives are designed to capture and remove the oxidized sulfur compounds present in the FCC unit regenerator and release them in the FCC riser. On release, the sulfur exits the FCC unit as hydrogen sulfide along with the cracked products in the reactor effluent. The hydrogen sulfide is processed in the gas plant downstream of the FCC unit. Extensive studies in the 1970s looked at the ...
