Are you ready for MARPOL?

As the International Maritime Organization (IMO) has decided to implement the MARPOL Annex VI, all ships must globally reduce their emissions of sulfur by 86% before 2020. This fact is bound to have a huge impact on the shipping as well as the refinery industry. But exactly what will happen? What options are there? What are the opportunities? Who will seize them? And how?   The MARPOL directive presents great opportunities for refineries. Whether you want to produce MARPOL ...

DuraSOx™

DURASOx™ SOx reduction additive is the culmination of intensive development work focusing on obtaining the most attrition-resistant SOx additive on the market without any performance compromises. It follows in the footsteps of Ketjen’s longest-marketed SOx additive, KDSOxTM, in that both take advantage of Ketjen’s patented hydrotalcite technology. SOx reduction additives are designed to capture and remove the oxidized sulfur compounds present in the Fluid Catalytic Cracking ...

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 ...

High octane C₅/C₆ cuts via isomerization Processes

C5/C6 isomerization is a must-have for refiners who want to maximize the profitability of their gasoline pool. This process can be adapted to various configurations and allows improving C5/C6 naphtha cut octane numbers up to 92 without constraints on olefins and sulfur. Axens is licensing a complete set of isomerization configurations in order to support refiners to resolve the evolving gasoline pool equation. COMMERCIAL EXPERIENCE With a powerful R&D support at both lab ...

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. This associated gas was to be used to strip additional H2S from the sour crude and to generate power in 3 gas fired turbines. Pertamina investigated several alternative sulfur recovery options, ...

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 ...
