Abstract: The present application provides a method for controlling soot make in a process for the gasification of a liquid carbonaceous feedstock. The gasification process comprises: partially oxidizing the carbonaceous feedstock in a gasifier to produce syngas; guiding the syngas from an outlet of the gasifier to a quench section; cooling the syngas in the quench section to provide cooled syngas; providing the cooled syngas to a soot removal unit; using the soot removal unit to remove solids from the cooled syngas, the soot removal unit providing a cleaned syngas stream and a waste slurry stream comprising the solids removed from the syngas; continuously monitoring a concentration of total suspended solids (TSS) in the waste slurry stream; providing the concentration of total suspended solids (TSS) to a control system. The control system continuously optimizes the gasification process to changes in concentration of total suspended solids, carbon-to-ash ratio, and optional additional parameters.

Abstract: A gasification system for the oxidation of a carbonaceous feedstock to provide a synthesis gas comprising: a reactor chamber for oxidizing the carbonaceous feedstock; a quench section for holding a bath of liquid coolant; an intermediate section having a reactor outlet opening through which the synthesis gas is conducted from the reactor chamber into the bath of the quench section; at least one layer of refractory bricks arranged on the reactor chamber floor, the lower end section of the refractory bricks enclosing the reactor outlet opening and defining the inner diameter thereof; the intermediate section including a number of halved tubes for liquid coolant arranged onto at least part of the reactor chamber floor on a side thereof opposite to the lower end section of the refractory bricks; and a pump system for circulating the liquid coolant through the halved tubes on the reactor chamber floor.

Abstract: A gasification system for the partial oxidation of a carbonaceous feedstock to at least provide a synthesis gas, the system comprising a reactor chamber and a quench section below the reactor chamber. An intermediate section connecting the reactor chamber to the quench section comprises at least one layer of refractory bricks arranged on and supported by the reactor chamber floor, the refractory bricks enclosing a reactor outlet opening. A membrane wall extends downwardly from the reactor outlet opening of the reactor chamber floor. A pump system is provided communicating with a source of a liquid coolant for circulating the liquid coolant through the tubes of the membrane wall.
