Methods of hydrotreating a mixture made up of oils of animal or vegetable origin and of petroleum cuts with intermediate stripping
ActiveUS20080161614A1Low costLimit consumption of hydrogenThermal non-catalytic crackingCatalytic crackingVegetable oilVolumetric Mass Density
The invention relates to a hydrotreating method (HDT) using two plants working under different operating conditions with an intermediate stripping for co-treating a mixture made up of oils of vegetable or animal origin and petroleum cuts (gas oil cuts (GO) and middle distillates) in order to produce gas oil fuel bases meeting specifications. The first plant (HDT1) is more particularly dedicated to the reactions concerning oils of vegetable or animal origin in comixture while pretreating the hydrocarbon feed, whereas the second plant (HDS2) works under more severe conditions to obtain diesel fuel according to standards, in particular in terms of effluent sulfur content, density and cold properties. The process economy, the activity and the stability of the catalyst of the second plant are greatly improved by the intermediate stripping.

Converting mist flow to annular flow in thermal cracking application
ActiveUS7097758B2Reduce flow rateShorten speedThermal non-catalytic crackingHydrocarbon oil cracking processGas phaseEngineering
A process to increase the non-volatile removal efficiency in a flash drum in the steam cracking system. The gas flow from the convection section is converted from mist flow to annular flow before entering the flash drum to increase the removal efficiency. The conversion of gas flow from mist flow to annular flow is accomplished by subjecting the gas flow first to at least one expander and then to bends of various degrees and force the flow to change directions at least once. The change of gas flow from mist to annular helps coalesce fine liquid droplets and thus being removed from the vapor phase.

Crude oil can be refined through a filtration media. Cavitation bubbles having localized areas of very high temperatures and pressures may be created thereby causing several physical and chemical phenomena, including thermal cracking of carbon-carbon bonds as the crude moves through the flux cartridge membrane. Heavy hydrocarbons are residues are thereby cracked into smaller lowering boiling molecules having a higher API gravity. Once the relatively smaller hydrocarbons pass through the flux cartridge membrane into the flux cartridge, the effluent can be routed to a second separator annulus. It should also be pointed out that lighter hydrocarbons formed can volatilize and special provisions may be needed to efficiently capture these gases.
