The gasifier injector may be coupled to or located inside the gasifier. | 03-08-2012 |
20120055331 | SYSTEM AND METHOD FOR CONTROLLING AN AIR SEPARATION UNIT - A system includes an air separation unit configured to separate air into an oxygen rich stream and a nitrogen rich stream and a purity control system configured to receive input indicative of a target diluent level. The purity control system is configured to control the air separation unit to adjust an oxygen percentage and a nitrogen percentage of the oxygen rich stream based on the target diluent level. | 03-08-2012 |
20130277615 | PARTIAL OXIDATION FEED SYSTEM AND METHOD - A system includes a slag additive slurry feed system configured to combine a slurrying agent, a mineral slag additive, and a liquid slurrying medium to generate a stabilized mineral slurry. The slurrying agent is configured to increase a viscosity of the stabilized mineral slurry. The system also includes a partial oxidation system configured to receive the stabilized mineral slurry, a feedstock, and oxygen into a gasifier reaction chamber. The partial oxidation system is configured to partially oxidize the feedstock to produce a gaseous product and a solid product. | 10-24-2013 |
20130327028 | SYSTEM AND METHOD FOR SLURRY HANDLING - A system includes a slurry depressurizing system that includes a liquid expansion system configured to continuously receive a slurry at a first pressure and continuously discharge the slurry at a second pressure. For example, the slurry depressurizing system may include an expansion turbine to expand the slurry from the first pressure to the second pressure. | 12-12-2013 |
20140124604 | ANNULAR INJECTOR ASSEMBLY AND METHODS OF ASSEMBLING SAME - An annular injector is described. The injector includes a first bayonet assembly and a second bayonet assembly each including a terminal end and a tip end. The second bayonet assembly is configured to be concentrically coupled at least partially about the first bayonet assembly. An outer diameter of the first bayonet assembly and an inner diameter of the second bayonet assembly vary at the tip end to define a first substantially annular nozzle. The first bayonet assembly includes a maximum outer diameter that is greater than a minimum inner diameter of the second bayonet assembly and at least a portion of at least one of the first bayonet assembly and the second bayonet assembly extends from the tip end to the terminal end. The injector includes a third bayonet assembly configured to be concentrically coupled at least partially about the second bayonet assembly to define a second substantially annular nozzle. | 05-08-2014 |
20150159097 | SYSTEM AND METHOD FOR CONTINUOUS SLAG HANDLING WITH DIRECT COOLING - A system includes a quench chamber configured to continuously receive a mixture of a gas and slag, and a downstream end portion coupled to the quench chamber. The quench chamber includes a quench sump configured to continuously separate the gas from the slag in the mixture via a quench liquid. The downstream end portion is configured to continuously convey a slag slurry to a depressurization system. The downstream end portion includes a cooling system configured to directly cool the slag slurry with a cooling fluid, and the slag slurry includes the separated slag and at least a portion of the cooling fluid | 06-11-2015 |
20150159503 | SYSTEM AND METHOD FOR CONTINUOUS SOLIDS SLURRY DEPRESSURIZATION - A continuous slag processing system includes a rotating parallel disc pump, coupled to a motor and a brake. The rotating parallel disc pump includes opposing discs coupled to a shaft, an outlet configured to continuously receive a fluid at a first pressure, and an inlet configured to continuously discharge the fluid at a second pressure less than the first pressure. The rotating parallel disc pump is configurable in a reverse-acting pump mode and a letdown turbine mode. The motor is configured to drive the opposing discs about the shaft and against a flow of the fluid to control a difference between the first pressure and the second pressure in the reverse-acting pump mode. The brake is configured to resist rotation of the opposing discs about the shaft to control the difference between the first pressure and the second pressure in the letdown turbine mode. | 06-11-2015 |
20150159654 | SYSTEM AND METHOD FOR CONTINUOUS SOLIDS SLURRY DEPRESSURIZATION - A system includes a first pump having a first outlet and a first inlet, and a controller. The first pump is configured to continuously receive a flow of a slurry into the first outlet at a first pressure and to continuously discharge the flow of the slurry from the first inlet at a second pressure less than the first pressure. The controller is configured to control a first speed of the first pump against the flow of the slurry based at least in part on the first pressure, wherein the first speed of the first pump is configured to resist a backflow of the slurry from the first outlet to the first inlet. | 06-11-2015 |
