An excess of very sour fuel gas can be the result when a refinery process heavy feedstocks into modern low-sulfur fuels. But refiners can in fact turn a profit from the additional fuel gas and even reduce sulfur emissions with fuel gas hydrotreatment.
Delayed coking MARPOL regulations are creating uncertainty about how best to invest in conversion capacity to comply or shift production to more profitable products.
Feed stream management In the not-so distant past, crude oil prices were hitting records everyday worldwide as downstream operators saw their margins decrease.
Hydrogen technology – Steam reforming hydrocarbons Treating fuel oils to meet the strict MARPOL sulfur regulations 2020 will require hydrogen. It is by far the most economical way to convert the sulfur compounds found in oil. When this organic sulfur is converted to H2S, it can be processed into commercial grade sulfuric acid or elemental...
Atmospheric Residue De-Sulfurization (ARDS) The introduction of new MARPOL regulations is expected to have a major impact on demand patterns in our industry. While this will present challenges to refineries, it will also create opportunities for those companies who optimize assets.
Soot and particulate removal Shipping, unlike land-based transportation, has not been subject to strict environmental regulations. It isn’t simply a question of whether or not companies were prepared to pay for technology improvements to reduce emissions. In fact, the technology was simply not available.
Conversion to methanol production The MARPOL legislation on bunker fuel for 2020 requires that sulfur emissions can be no higher than 0.5 wt% of the fuel used. Within these parameters, methanol is emerging as an alternative to bunker fuel because it’s clean and contains no sulfur or NOx and is soot-free.
Slurry technology Thanks to MARPOL, refineries have more incentive than ever to exit the bunker fuel market and shift their production to lucrative products such as gasoline, jet fuel and diesel.
Crude overflash hydrocracking One approach to reducing the dependency on the fuel oil market has been to revamp or install more conversion capacity in refineries. Such projects have been an extremely cost-effective way for a refinery to shift its product slate.
Sulfur management In the race to achieve more and deeper desulfurization of fuel oil and other refinery products, the challenges faced by refineries are many. For some, the issue is capacity. Existing H2S gas treatment facilities such as Claus plants may not have sufficient capacity to treat additional H2S gas. In other cases, refiners need...
In 2014, Haldor Topsoe A/S and its Italian partner Ecospray Technologies S.r.l. launched a groundbreaking catalytic process technology called ECO-Jet that can signiﬁcantly reduce harmful emissions from marine vessels.
