  • Enhanced temperature control of bitumen froth treatment process
    Patent number: 11261383
    Abstract: A method for pre-treating bitumen froth for mixing with solvent for froth treatment includes heating the froth to a froth-solvent mixing temperature below the solvent flash temperature and suitably high to provide reduced bitumen viscosity sufficiently low for complete mixing of the solvent and the froth prior to introduction into a separation apparatus. A method of improving energy use in froth treatment includes reducing heat provided to the solvent, increasing heat provided to the froth prior to adding the solvent to reduce bitumen viscosity and adding the temperature-reduced solvent to the heated froth. A froth treatment separation process includes trim heating first and second solvent streams to adjust the first and second stage separation temperatures.

  • Process and apparatus for recycling hydrogen to hydroprocess biorenewable feed
    Patent number: 11136514
    Abstract: The process and apparatus enables purification of a recycle hydrogen gas stream from hydroprocessing biorenewable feedstocks. The recycle gas stream is fed to a methanator reactor to hydrogenate carbon monoxide in the gas stream to water and methane. Other acid gases can be removed by scrubbing preferably upstream of the methanator. Removal of carbon monoxide omits the need for a hydrogen purge stream to avoid carbon monoxide accumulation and enables use of the hydrogen for a downstream hydroisomerization reaction.
