Gasifier preheater fuel and moderator injection apparatus, systems and methods are provided. A preheater distributor ring is securely mounted within the shell dome of a gasification vessel, for the selective discharge of preheat fuel and oxidizer into the vessel during preheating operations, or for the selective discharge of moderating agents into the vessel during normal gasification operations.

The present application thus provides a gasifier cooling system for cooling a flow of hot syngas from a gasifier. The gasifier cooling system may include a radiant syngas cooler, a quench chamber, and a convective syngas cooler such that the flow of syngas flows through the quench chamber or the convective syngas cooler.

A method of reducing the concentration of at least one sulfur compound in a process stream and for recovering at least one sulfur compound from a process stream are provided. A process stream is delivered to a vessel, wherein the vessel comprises an adsorbent material. At least one solvent is transferred into the vessel. One or more fluids are then removed from the vessel. At least one of the fluids removed from the vessel comprises a clean gas. The adsorbent material may be regenerated to yield a high concentration of the at least one sulfur compound.
