| 20090139902 | PROCESS FOR CATALYTIC HYDROTREATING OF SOUR CRUDE OILS - A continuous process for upgrading sour crude oil by treating the sour crude oil in a two step process that includes a hydro-demetallization section and a hydro-desulfurization section, both of which are constructed in a permutable fashion so as to optimize the operating conditions and catalyst lifespan to produce a high value crude oil having low sulfur and low organometallic impurities. | 06-04-2009 |
| 20100018904 | Prerefining Process for the Hydrodesulfurization of Heavy Sour Crude Oils to Produce Sweeter Lighter Crudes Using Moving Catalyst System - A pre-refining catalytic hydrotreating process for the desulfurization, demetallization, and upgrading of heavy, sour crude oils operating at a moderate temperature and pressure through the utilization of moving catalyst bed technology. | 01-28-2010 |
| 20100025291 | Process for the Treatment of Heavy Oils Using Light Hydrocarbon Components as a Diluent - The present invention relates to a process for the treatment of heavy oils using a catalytic hydrotreating process. More specifically, the invention relates to the presence of light hydrocarbon components in conjunction with the heavy oils for improved treatment of the heavy oils utilizing moderate temperature and pressure. | 02-04-2010 |
| 20100025293 | Process for the Sequential Hydroconversion and Hydrodesulfurization of Whole Crude Oil - The invention relates to a method for removing sulfur from crude oils using a catalytic hydrotreating process operating at moderate temperature and pressure and reduced hydrogen consumption. The process produces sweet crude oil having a sulfur content of between about 0.1 and 1.0 wt % in addition to reduced crude density. The method employs least two reactors in series, wherein the first reactor includes a hydroconversion catalyst and the second reactor includes a desulfurization catalyst. | 02-04-2010 |
| 20110083996 | Alternative Process for Treatment of Heavy Crudes in a Coking Refinery - The present invention relates to a process for the pretreatment of heavy oils using a catalytic hydrotreating process prior to introduction to a refinery. More specifically, the invention relates to the use of an HDM reactor and an HDS reactor in order to improve the characteristics of the heavy oil, such that when the oil is introduced into the refinery, the refinery can achieve improved throughputs, increased catalysts life, increased life cycles, and a reduction in overall operation costs. | 04-14-2011 |
