Abstract:
A method includes monitoring a pressure of a gasification system after gasifier shutdown via a pressure sensor, wherein the gasification system includes a gas treatment system and a gasifier configured to output syngas to the gas treatment system during gasification. In addition, the method includes depressurizing the gasification system after gasifier shutdown by opening a flare valve to release gas from the gasifier and the gas treatment system to an atmosphere. The method also includes pressurizing the gasification system after gasifier shutdown, when the monitored pressure reaches a lower pressure threshold, by establishing multiple purge flows of inert gas into the gasification system to remove residual gas from the gasification system. The multiple purge flows are established at different times and at different locations within the gasification system relative to each other.
Abstract:
A gasification quench chamber dip tube component is disclosed. The dip tube includes an elongate hollow element that has a first intake end and a second discharge end that is located distally opposite the intake end. The second discharge end includes either a plurality of elongate openings that are displaced circumferentially around the hollow element or a plurality of elongate elements displaced circumferentially around the hollow element thereby defining a plurality of elongate spaces therebetween that extend axially from the second discharge end. A quench chamber that employs the dip tube is also disclosed.

Abstract:
A method for the delivery of a catalyst to a polymerization reactor is disclosed, comprising: contacting a catalyst with a carrier fluid comprising an inert hydrocarbon in gaseous form, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.; and flowing the carrier fluid to the polymerization reactor such that the carrier fluid transports the catalyst to the polymerization reactor. A catalyst delivery system is disclosed, comprising: a catalyst vessel for containing a catalyst; a catalyst injection line for delivering the catalyst to a polymerization reactor, the catalyst injection line being in fluid communication with the catalyst vessel and the polymerization reactor; and a carrier fluid line in fluid communication with the catalyst injection line for delivering a carrier fluid comprising an inert hydrocarbon to the catalyst injection line, the inert hydrocarbon having a normal boiling point of about −1° C. to about 81° C.
Abstract:
In one embodiment, a gasification system component, such as a quench unit or scrubber may retain of pool of a cooling fluid for cooling another fluid. The gasification system component includes a flow damping mechanism designed to dampen flow of the cooling fluid, the other fluid, or both, within the gasification system component. The flow damping mechanism may be disposed in an inner chamber formed between a dip tube and a draft tube or disposed in an outer chamber formed between the walls of the gasification system component and the draft tube. The flow damping mechanism also may be disposed between the inner chamber and the outer chamber.
Abstract:
Techniques, systems and material are disclosed for thermochemical regeneration of biomass into renewable engineered fuel, storage of the renewable engineered fuel, respeciation of the renewable engineered fuel and transport. In one aspect, a method includes generating low density hydrogen fuel from biomass dissociation at a first location of a low elevation. The low density hydrogen fuel is self-transported in a pipeline to a second location at a higher elevation than the first location by traveling from the first location to the second location without adding energy of pressure. A high density hydrogen carrier is generated at the second location of higher elevation by reacting the low density hydrogen fuel with at least one of a carbon donor, a nitrogen donor and an oxygen donor harvested from industrial waste. The high density hydrogen carrier is delivered to a third location of a lower elevation than the second location while providing pressure or kinetic energy.
