  • Method and system for controlling soot make in synthesis gas production
    Patent number: 10941361
    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.
