SYSTEM AND METHOD FOR CONTINUOUS SOLIDS SLURRY DEPRESSURIZATION

摘要

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. r - - - - 9 OXYGEN SLAG CARBONACEOUS .ADDITIlVE| FEEDSTOCK '-OP-O-r--3 20A |_MODERATOR_" 30 - - - - -56 43 38-, 32 32 --- 24 54 40 , 150 j GAS TREATMENT 11 QUENCH 46 SYSTEM LIQUID -52 1SYSTEM 442-4 2 2 58 4 12 5 9 r61 4 COOLING COOLING 74 L SYSTEM : FLUID ------- CONTROLLER ------- kk '64 --- 90 94 74 P2 DOWNSTREAM TV 74 |SLAG PROCESSING 74 I 78-~, '-------' |-COLD |_86 |wmE_ -'776 88 80
