摘要： The present invention is directed to a method for irradiating of solids containing petroleum or petroleum derived compounds (PPDCs), such as soils, oily sludge, drill cuttings, sediments, and non-commercial petroleum industry products, with electron beams in order to physically and/or chemically alter the composition of the PPDCs. The method includes the step of separating PPDC gas and liquids in the presence of a gas driver. Optionally, the method includes the steps of treating off-gases and applying one or more amendments to PPCD-impacted solid material pre- irradiation, post- irradiation, or during electron beam irradiation.

摘要： The present invention is directed to a method for the prediction of coke morphology from feed characteristics using cross-polarized light optical microscopy, image segmentation, and statistical analysis. In particular, the method comprises performing a microcarbon test (MCRT) on a coker feed, ASTM D 4530 to produce a MCRT coke sample, using cross-polarized light optical microscopy at 100X, 200X or 500X, preferably 500X, to produce a photo of the MCRT coke sample, using machine learning segmentation software to produce a segmented output file that comprises a partitioned image with multiple segments, determining structural parameters of output file by applying statistical analysis weighted by area, and correlating the resulting statistical analysis to a coke morphology. Preferably, the structural parameter is Feret maximum, number of particles less than or equal to 100 microns or area calculated by statistical analysis.

摘要： Disclosed are system (100) and method for treating contaminated material (2). The material is heated by nonconductive and nonconvective heating in a vacuum chamber (4) such that the surface of the material is heated without significant heating of the air within the chamber. The surface of the material is heated to at least a volatilization temperature of the contaminants or to a decomposition temperature of one or more compounds in intimate contact with the contaminants, so that the concentration of contaminants in the material is reduced. Exhaust is removed from the chamber and cooled. A solids and/or liquids collector removes condensed solids and/or liquids and has a gas outlet connected to a vacuum pump (17).

The process of the present invention can be also carried out at higher temperatures such as by injecting steam with the one or more hydrocarbon solvents and the one or more asphaltene precipitant additives into the well in any order.
