Machine Learning for Downstream Oil & Gas Refineries: Applications for Solvent Deasphalting
This thesis seeks to provide continuous DAO yield estimations for an SDA unit by constructing modern machine learning models using data sets from a commercial downstream oil and gas refinery in the United States. These data sets include plant operating parameters and laboratory measurements for …

Partial Upgrading of Bitumen Through Combinations of Deasphalting and Visbreaking
… to do so is to combine visbreaking (VIS) and solvent deasphalting (SDA) to obtain a lower density and viscosity bitumen. Visbreaking is a mild thermal cracking process that reduces viscosity and density but risks asphaltene precipitation and coke formation at high conversions. Solvent …

Effects of Variables on a Soaker-Stripper Reactor for Thermal Cracking of Deasphalted Oil
… to markets. One effective scheme in use employs Solvent Deasphalting (SDA), a versatile upgrading process that uses light alkanes to precipitate the asphaltic phase from the feedstock, producing Deasphalted Oil (DAO), a stream with reduced asphaltenes and metal content. In that industrial scheme …

Measurement and Modeling of Pentane-Diluted Bitumen Phase Behaviour
… a key factor in the design and optimization of solvent-assisted heavy oil recovery processes and solvent deasphalting processes. However, data and comprehensive models are lacking for these mixtures. Crude oil phase behavior is typically modeled using cubic equations of state (CEoS). While CEoS …
