  • Process to recover energy from hot gas
    Patent number: 6996989
    Abstract: A process to recover energy from a gas having a temperature of above 650° C. and an absolute pressure of more than 1.7 bar and having non-solidified alkali containing compounds and particles by performing the following steps: (a) cooling the gas to a temperature of below 550° C. by means of a shell-tube heat exchanger, wherein the hot gas is passed at the shell side and coolant water is passed at the tube side, wherein steam is formed, from which steam energy is recovered; (b) separating the particles from the gas by means of one or more sequentially arranged centrifugal separation devices to a dust level of below 400 mg/Nm3; and (c) expanding the gas in an expander to recover energy.
