  • Patent number: 8449776
    Abstract: Our idea is a new procedure that can be used to clean up and recover oil from spills or oil leaking from damaged ships or rigs. The reclamation is accomplished by restoring the oil's light density. This is accomplished with density control by adding light cycle oil, (LCO), with a density of 0.82 g/ml, to the oil being recovered for the purpose of reprocessing in refineries. Recovery is made possible through the application of solubility rules found in organic chemistry. LCO is a mixture of many different molecular weight hydrocarbons that have many different numbers of carbons in their chains, branches, or rings. Each of these hydrocarbons dissolves a small part of the oil preparing the mixture for collection and reprocessing as refinery feedstock. Furthermore, this idea can prevent the need for landfill storage and offset the cost of recovery.

  • Publication number: 20130056395
    Abstract: Processes are described for extracting hydrocarbon from a mineable deposit, such as bitumen from oil sands. The integration of solvent-based extraction processes with aqueous extraction processes is described. In one embodiment, water is removed from an aqueous bituminous feed that is then directed into a solvent-based extraction process. In another embodiment, a stream produced through solvent extraction is directed into a water-based extraction process. In the solvent-based extraction processes, agglomeration of fines may be employed to simplify subsequent solid-liquid separation. The process permits recovery of hydrocarbon that has conventionally may have been too difficult to recover from oil sands processing, and thus has previously been lost. Advantageously, a fungible product can be formed more efficiently according to certain integrated processes described herein.

  • Patent number: 7967974
    Abstract: A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a constructed permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume having substantially permeable side walls and a substantially impermeable cap. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom without contamination or substantial leaching of materials outside of the impoundment. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.

  • Patent number: 7906014
    Abstract: A method of recovering hydrocarbons from hydrocarbonaceous materials can include forming a stationary permeability control infrastructure. This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydrocarbonaceous material can be introduced into the control infrastructure to form a permeable body of hydrocarbonaceous material. The permeable body can be heated sufficient to remove hydrocarbons therefrom within a temperature range which is sufficient to substantially avoid formation of carbon dioxide or non-hydrocarbon leachates. During heating the hydrocarbonaceous material is substantially stationary as the constructed infrastructure is a fixed structure. Removed hydrocarbons can be collected for further processing, use in the process, and/or use as recovered.
