AI Technical Summary

⚠Technical Problem

Existing gasification processes face challenges in effectively separating and recovering solids of different densities from slag-containing water, such as slag and fly ash, which can cause fouling and clogging in downstream equipment due to their accumulation, and there is a need for improved methods to classify and utilize these solids for different purposes.

⚗Method used

A process involving multiple separation stages, including gravity separation and hydrocyclone methods, is used to separate slag-containing water into distinct products based on solid density, allowing for the recovery of lighter and heavier solids and water-soluble compounds, utilizing two separate vessels for efficient classification and recycling of these fractions.

🎯Benefits of technology

The process enables effective separation and recovery of solids and compounds with different compositions, enhancing the ability to utilize these products for various applications and reducing fouling in downstream equipment by effectively managing solid accumulation.

Abstract

Disclosed are treatment configurations for recovering portions of solid-containing water (e.g., slag-containing water) having different compositional and quality characteristics and useful for different purposes. Solid-containing water generally contains solids of different types (e.g., densities), optionally together with dissolved water-soluble compounds such as chloride species (e.g., HCl) and nitrogen species (e.g., NH3). Some or all of the recovered products may have different compositions (e.g., weight percentages) with respect to different types of solids and / or water-soluble compounds. The disclosed separations can be actually implemented in or integrated with several processes that generate solid-containing water, with gasification and its associated synthesis gas cooling operations being exemplified.
