Abstract:
A multipurpose chemical additives (MPC) is disclosed to mitigate fouling in hydrocarbon refinery processes, such as in a heat exchanger. A method for reducing fouling of a hydrocarbon is also disclosed that includes (i) providing a crude hydrocarbon for refining process; and (ii) adding an additive to the crude hydrocarbon.
Abstract:
In various aspects, systems and methods are provided for integration of molten carbonate fuel cells with a Fischer-Tropsch synthesis process. The molten carbonate fuel cells can be integrated with a Fischer-Tropsch synthesis process in various manners, including providing synthesis gas for use in producing hydrocarbonaceous carbons. Additionally, integration of molten carbonate fuel cells with a Fischer- Tropsch synthesis process can facilitate further processing of vent streams or secondary product streams generated during the synthesis process.
Abstract:
Systems and methods are provided for capturing CO 2 from a combustion source using molten carbonate fuel cells (MCFCs). The fuel cells are operated to have a reduced anode fuel utilization. Optionally, at least a portion of the anode exhaust is recycled for use as a fuel for the combustion source. Optionally, a second portion of the anode exhaust is recycled for use as part of an anode input stream. This can allow for a reduction in the amount of fuel cell area required for separating CO 2 from the combustion source exhaust and/or modifications in how the fuel cells are operated.

A method for treating an emulsion of a hydrocarbon is disclosed. The method includes providing an emulsion of a crude hydrocarbon, and adding an additive to the emulsion to obtain a treated hydrocarbon.
Abstract:
In various aspects, systems and methods are provided for operating molten carbonate fuel cells with processes for cement production. The systems and methods can provide process improvements including increased efficiency, reduction of carbon emissions per ton of product produced, and simplified capture of the carbon emissions as an integrated part of the system. The number of separate processes and the complexity of the overall production system can be reduced while providing flexibility in fuel feed stock and the various chemical, heat, and electrical outputs needed to power the processes.
Abstract:
In various aspects, systems and methods are provided for operating a molten carbonate fuel cell to reduce or minimize losses due to loss of heat energy. A molten carbonate fuel cell can be operated based on a desired ratio of heat generated by exothermic reactions in the fuel cell relative to heat consumed by endothermic reactions in the fuel cell and any optional integrated endothermic reaction stages.

Abstract:
In various aspects, systems and methods are provided for operating a molten carbonate fuel cell, such as a fuel cell assembly, with increased production of syngas or hydrogen while also reducing or minimizing the amount of CO 2 exiting the fuel cell in the cathode exhaust stream. This can allow for improved efficiency of syngas production while also generating electrical power.
