Effects of the addition of coal tar pitch-based mesocarbon microbeads on the preparation of mesophase pitch [PDF]
E3S Web of Conferences, 2021 Mesophase pitch was prepared by co-carbonization of the hydrocracking tail oil (HCTO) and coal tar pitch-based mesocarbon microbeads (MCMB). The effects of the addition amount of coal tar-based MCMBs on the C/H atomic ratio, softening point, carbon ...

Modelling In-situ Upgrading of Heavy Oil Using Operator Splitting Methods [PDF]
, 2014 Heavy oil and oil sands are important hydrocarbon resources that account for over 10 trillion barrels (Meyer et al., 2007), nearly three times the conventional oil in place in the world.

Heavy oil production with energy effective steam-assisted gravity drainage [PDF]
, 2016 In reservoirs with extra heavy oil and bitumen, thermal methods are used to reduce the viscosity, in order to extract the oil. Steam-assisted gravity drainage (SAGD) is a thermal method where continuous steam injection is used.

Oil & Gas Science and Technology, 2004 Heavy crude oils cannot be transported by pipeline without a prior reduction of their viscosity. This is commonly obtained by blending the oil with light hydrocarbons. In that case, the resulting viscosity of the mixture depends only on the dilution rate, on the respective viscosities and densities of the oil, and of the diluent.

Ethylene Separation via Hydrate Formation in W/O Emulsions
Energies, 2015 An hybrid absorption-hydration method was adopted to recover C2H4 from C2H4/CH4 binary gas mixtures and the hydrate formation conditions of C2H4/CH4 mixtures was studied experimentally in diesel in water (w/o) emulsions. Span 20 at a concentration of 1.0

Restart time correlation for core annular flow in pipeline lubrication of high-viscous oil [PDF]
, 2016 One of the fundamental questions that must be addressed in the effective design and operation of pipeline lubrication of heavy oil is; “how much time will be needed to restart a blocked core annular flow (CAF) line after shutdown due to fouling or pump ...
