AI Technical Summary
Technical Problem
Current gasification processes face challenges in efficiently integrating and utilizing products from syngas purification, particularly CO2-enriched products, which often require specialized handling to avoid hazardous and greenhouse gas emissions.
Method used
The process involves recycling CO2-enriched products from syngas purification back into the gasification process or upstream operations, optimizing their use as utilities or for sequestration, thereby reducing emissions and improving process economics.
Benefits of technology
This approach simplifies process flows, reduces capital and operating costs, enhances product yields, and decreases emissions of hazardous components and greenhouse gases, making the gasification process more economically attractive.

Abstract
Gasification processes utilizing carbonaceous feeds and preferably biomass are disclosed, which can implement one or more strategies for integration of products, such as CO2-enriched products, that are generated from syngas purification, and into which CO2 and possibly other acid gases are preferentially rejected. Such products, which necessarily result as a consequence of obtaining a purified syngas product that is desirably substantially free of components other than H2 and CO, are often provided at different pressures and with corresponding, different compositions. Advantageously, these products can be effectively "matched" or "tailored" to the process and utility needs in the overall production of renewable products (e.g., liquid hydrocarbons or purified hydrogen). Important advantages relate to the discovery of economically attractive solutions for reducing potential CO emissions in CO2 that is vented to the atmosphere.
