Integrated One-Dimensional Modeling of Asphaltene Deposition in Wellbores/Pipelines [PDF]

open access: yes
—Asphaltene deposition in wellbores/pipelines causes serious production losses in the oil and gas industry. This work presents a numerical model to predict asphaltene deposition in wellbores/pipelines. This model consists of two modules: a Thermodynamic

Prediction of the Gas Injection Effect on the Asphaltene Phase Envelope

open access: yesOil & Gas Science and Technology, 2015
Asphaltene instability may occur when pressure, temperature and compositional variations affect the reservoir oil. Permeability reduction, wettability alteration, and plugging of wells and flow lines are the consequences of this phenomenon. Therefore, it

The modification of bituminous materials using tall oil pitch : a thesis presented in partial fulfilment of the requirements for the degree of Master of Technology in Chemical Technology at Massey University, New Zealand [PDF]

open access: yes, 2003
There are economic, occupational safety and health, and environmental advantages in using tall oil pitch (TOP) as a bitumen extender. However, before bitumen modified with TOP can be used commercially in New Zealand, it must meet the requirements of the ...

Space station molecular sieve development [PDF]

open access: yes
An essential function of a space environmental control system is the removal of carbon dioxide (CO2) from the atmosphere to control the partial pressure of this gas at levels lower than 3 mm Hg.
