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.

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 ...

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. ...

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 ...

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 ...
