181 PROCESS FOR THE PRODUCTION OF LOW SULFUR, LOW OLEFIN GASOLINE PCT/US2005/029395 2005-08-18 WO2006049673A2 2006-05-11 ROCK, Kerry, L.; XOING, Yi-Gang; JUDZIS, Arvids, Jr.

A process for the production of low sulfur, low olefin gasoline wherein a cracked naphtha, such as a full boiling range cracked naphtha, is first separated by fractional distillation into at least two fractions while simultaneously selectively hydrogenating the polyunsaturated compounds contained therein. The mono olefins in the light fraction are then subjected to etherification with alcohol to produce ethers or hydration with water to produce alcohols. The heavy fraction is subjected to sulfur removal by hydrodesulfurization or chemisorption. The two fractions are then combined to produce a low sulfur, low olefin gasoline.

182 PROCESS FOR SULFUR REDUCTION IN NAPHTHA STREAMS PCT/US0235294 2002-11-04 WO03050207A8 2004-10-21 GROTEN WILLIBRORD A
A process for fractionating and treating of a full range naphtha stream. The full boiling range naphtha stream is first split into a light boiling range naphta, an intermediate boiling range naphtha and a heavy boiling range naphtha. The bottoms are subjected to hydrodesulfurization and the effluent combined with the intermediate boiling range naphtha containing thiophene and thiophene and thiophene mercaptans and subjected to a second hydrodesulfurization. The effluent from the polishing reactor may be combined with the light boiling range naphtha to produce a new full boiling range naphtha containing substantially less total sulfur than the original feed. The mercaptans in the light naphtha may be removed by thioetherification prior to splitting or by wet caustic wash afterwards. The object being to meet higher standards for sulfur removal, by treating the components of the naphta feed with the process that preserves the olefinic while most expediently removing the sulfur compounds.

191 Polished turbine fuel US16780517 2020-02-03 US11104856B2 2021-08-31 Mohammed Wohaibi; Tom F. Pruitt
Turbine fuel provided for large-scale land based turbines used by utilities for producing electricity and desalinated water, and for large mobile engines and turbines in marine and remote applications where only liquid fuels are available. Use results in less corrosion, ash formation and emissions (NOx, SOx, CO2 and noxious metals) than firing contaminated heavy crude, refinery residual oils or high sulfur fuel oils. Manufacture is by decontaminating crude oils, non-conventional crudes, and other highly contaminated feeds. Each fuel is produced as a single product of unit operations, not ex-plant blend of various refinery products, yet using an apparatus configuration less complex than conventional crude oil refining. These fuels can be fired by advanced high efficiency turbines of combined cycle power plants having hot flow paths and heat recovery steam generation systems susceptible to corrosion, which systems cannot otherwise risk contaminated heavy crudes or refinery residual oils feeds.

200 Integrated isomerization and hydrotreating process US13559802 2012-07-27 US10100261B2 2018-10-16 Omer Refa Koseoglu
Deep desulfurization of hydrocarbon feeds containing undesired organosulfur compounds to produce a hydrocarbon product having low levels of sulfur, i.e., 15 ppmw or less of sulfur, is achieved by flashing the feed at a target cut point temperature to obtain two fractions. A low boiling temperature fraction contains refractory, sterically hindered sulfur-containing compounds, which have a boiling point at or above the target cut point temperature. A high boiling temperature fraction, having a boiling point below the target cut point temperature, is substantially free of refractory sulfur-containing compounds. The high boiling temperature fraction is contacted with isomerization catalyst, and the isomerized effluent and the low boiling temperature fraction are combined and contacted with a hydrotreating catalyst in a hydrodesulfurization reaction zone operating under mild conditions to reduce the quantity of organosulfur compounds to an ultra-low level.
