Abstract: Heavy oil feeds are hydroprocessed in the presence of a solvent under conditions that provide a variety of benefits. The solvent can be an added solvent or a portion of the liquid effluent from hydroprocessing. The processes allow for lower pressure processing of heavy oil feeds for extended processing times or extended catalyst lifetimes be reducing or mitigating the amount of coke formation on the hydroprocessing catalyst.

Abstract: A renewable fuel may be obtained from a bio-oil containing C3-C5 oxygenates. In a first step, the bio-oil is subjected to a condensation reaction in which the oxygenates undergo a carbon-carbon bond forming reaction to produce a stream containing C6+ oxygenates. In a second step, the stream is hydrotreated to produce C6+ hydrocarbons.

Abstract: A process for recovering a light hydrocarbon, such as ethane, from a sour hydrocarbon gas. The process involves mixing the sour hydrocarbon gas with an azeotrope inhibitor and then passing the mixture into a first distillation column. The first distillation column is operated under a set of temperature and pressure conditions in which the light hydrocarbon is substantially separated from the mixture as an overhead vapor product. The sour species in the mixture can be recovered by passing the bottoms liquid product into a second distillation column under a second set of temperature and pressure conditions in which the sour species is separated as a second overhead vapor product.
Abstract: The present technology is generally directed to systems and methods of controlling or reducing the output rate of a coke oven through gas sharing providing an extended process cycle. In some embodiments, a method of gas sharing between coke ovens to decrease a coke production rate includes operating a plurality of coke ovens to produce coke and heated exhaust gases. In some embodiments, a first coke oven is offset in operation cycle from a second coke oven. The method further includes directing the heated exhaust gases from the first coke oven to the second coke oven while the second coke oven is mid-cycle. The heat transfer allows the second coke oven to extend its cycle while staying above a critical operating temperature. By extending the operational cycle while generally maintaining output per cycle, overall production is decreased.
