Abstract

The invention provides a hydrothermal dewatering system for removing moisture from coal or other carbonaceous solid fuel materials, the system having an autoclave 19 with a heater to heat the materials to an elevated temperature and under pressure, where the autoclave is a continuous flow autoclave. Preferably, the autoclave comprises a positive displacement pumping system 7 to drive the materials in a slurry in a continuous flow through the autoclave, an ohmic heater 9 to heat the flowing materials in the autoclave rapidly and uniformly to the required temperature, and pressure let down valve means 12 at the outflow of the autoclave to reduce the pressure of the out-flowing slurry rapidly and in a controlled manner. In a further aspect, a process for carrying out hydrothermal dewatering at elevated pressure and temperature is disclosed, where the process includes the application of pressure from positive displacement pumps and heating by ohmic heating.
