A heat exchangerincludes a conduitfor conveying cooling fluid relative to a body to be cooled. A heat transfer arrangementis arranged in communication with an interior of the conduit, the heat transfer arrangementand the conduittogether defining an assembly that is mountable adjacent the body to be cooled, convective heat exchange occurring, in use, due to movement of the cooling fluid relative to the body and to the heat transfer arrangementof the assembly and radiant heat exchange occurring between the body and at least part of the heat transfer arrangementof the assembly.

In one aspect, a process for treating woody plant material is provided, the process involving contacting the plant material with a continuous flow of an aqueous ethanol solution at elevated temperature and pressure under conditions that promote extraction of ethanol-soluble lignin from the plant material and retention of hemicellulose sugars, xylose and cellulose in the treated plant material solids. In another aspect, a process for extracting hemicellulose sugars from lignin-depleted plant material solids is provided, the process involving contacting lignin-depleted plant material with water at elevated temperature and pressure under conditions that promote extraction of hemicellulose sugars from the plant material; and recovering hemicellulose sugars from the liquid mixture.
