Methods and systems for cooling hot product gas
Methods, systems, and apparatus for cooling hot product gas are provided. The method includes introducing cooled solid into a downward or upward contactor where heat transfer between solid and product gas. After separating solid and product gas in cyclone system, cooled product gas flows to process downstream and hot solid is introduced into a fluidized bed solid cooler from the cyclone dipleg. The hot solid flows through the shell side of the fluidized bed cooler and exchanger heat with the coolant in the tube side. The cooled solid flows through a mechanical or non-mechanical valve back into the downward/upward contactor and complete the cycle.
