The present invention relates to a method for conditioning a soot-containing syngas stream in a single integrated apparatus containing a scrubbing vessel wherein particulate matter is decoupled from the waste water stream.

Integrated process and unit operation for conditioning a soot-containing syngas

A high purity ceramic oxygen generator incorporating a module utilizing a plurality of tubular ceramic membrane elements and configured to operate in: (i) a pressurizing mode to separate oxygen from an oxygen containing feed stream when an electric potential difference is applied to induce oxygen ion transport in an electrolyte thereof; and (ii) an idle mode when the electric potential difference is removed. The ceramic oxygen generator further includes one or more manifolds as well as one or more automatic purge valves located upstream of the oxygen receiving tank. The purge valve is opened for a pre-set duration upon initiation of the pressurization mode to purge any nitrogen or other contaminating gas that diffuses into the ceramic oxygen generator during idle mode thereby ensuring the desired purity level of oxygen is received by the oxygen receiving tank.

High purity ceramic oxygen generator

A separation method and apparatus that separates a component from a feed stream by use of a membrane in which separation is driven, at least in part, by a sweep stream. The sweep stream may be pumped to a supercritical pressure and then heated to at least near supercritical temperature, at least in part, through heat exchange with a component laden sweep stream being discharged from the membrane. A multi-component mixture can also be used that will produce the sweep stream as a vapor as a result of the heat exchange. The component laden sweep stream, due to cooling through the indirect heat exchange, will form a two-phase fluid that can be phase separated into a vapor phase enriched in the component that can be taken as a product and a residual liquid that can be recirculated in the formation of the sweep stream in the liquid state.
