Abstract
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.
Claims21
A system, comprising:
- 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, wherein the slurrying agent is configured to increase a viscosity of the stabilized mineral slurry, the slag additive slurry feed system comprises a slurry tank having the stabilized mineral slurry, and the slurrying agent comprises at least one of carboxymethyl cellulose, sucrose, long-chain polymers, soluble polymers, or polymers capable of colloidal suspension, or a combination thereof;
- and
- a partial oxidation system configured to receive the stabilized mineral slurry, a feedstock, and oxygen into a gasifier reaction chamber, wherein the partial oxidation system is configured to partially oxidize the feedstock to produce a gaseous product and a solid product.
A system, comprising:
- 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, wherein the slurrying agent is configured to increase a slurry viscosity of the stabilized mineral slurry;
- a gasifier configured to receive the stabilized mineral slurry, a feedstock, and oxygen into a gasification chamber, wherein the gasifier is configured to gasify the feedstock to produce a syngas and a slag;
- a sensor configured to provide a signal related to a slag viscosity of the slag;
- and
- a slag additive slurry feed control system configured to receive the signal and input indicative of a target slag characteristic, wherein the slag additive slurry feed control system is configured to control the slag additive slurry feed system to adjust relative proportions of the slurrying agent, the mineral slag additive, and the liquid slurrying medium comprising the stabilized mineral slurry based on the signal and the target slag characteristic.
A method, comprising:
- combining a slurrying agent and a liquid slurrying medium to generate a mixture in a slurry tank of a slag additive slurry feed system, wherein the slurrying agent comprises at least one of carboxymethyl cellulose, sucrose, long-chain polymers, soluble polymers, or polymers capable of colloidal suspension, or a combination thereof;
- combining the mixture and a mineral slag additive to generate a stabilized mineral slurry using the slag additive slurry feed system, wherein the slurrying agent is configured to increase a viscosity of the stabilized mineral slurry;
- receiving the stabilized mineral slurry, a feedstock, and oxygen into a partial oxidation system;
- and
- partially oxidizing the feedstock to produce a gaseous product and a solid product.
