Patent number: 9441172Abstract: The mercury in crude oils is managed during the refining process to reduce its occurrence in refined petroleum products as well as in refinery emissions and wastes by converting the mercury, which may typically be present in the crude in elemental, ionic or combined organic (organomercury) forms, by operating the refinery on a blend of crudes comprising a mercury-containing crude of low sulfur content and a high sulfur crude. For optimal mercury control, the refinery should be operated in a high conversion regime, preferably with hydroprocessing (severe hydrotreating, hydrocracking) suitable for converting refractory, non-reactive sulfur compounds in the high sulfur crudes to more reactive forms including, for example, hydrogen sulfide, which will combine with the mercury present from the mercury-containing crude to form solid mercury sulfides which may be removed as solid waste by-products and disposed of in an environmentally acceptable manner.Type: GrantFiled: June 16, 2014Date of Patent: September 13, 2016Assignee: ExxonMobil Research and Engineering CompanyInventors: Bryan M.

Patent number: 9433875Abstract: A system and process for removing divalent cations from a rich MEG feed stream is presented. An ion exchange bed containing a cation exchange resin adsorbs the divalent cations in the rich MEG feed stream as it flows through the ion exchange bed. After the divalent ions have been removed, the feed stream flows through a flash separator and a distillation column to reclaim MEG. Alternatively, the feed stream flows through a distillation column to regenerate MEG. The spent cation exchange resin may be regenerated in place using a regeneration brine comprised of sodium chloride and water. After use, the regeneration brine may be disposed as waste or recycled to the brine storage tank and re-used to regenerate the cation exchange resin.Type: GrantFiled: August 24, 2012Date of Patent: September 6, 2016Assignee: Cameron International CorporationInventors: Daniel W.
