Abstract
A kettle reboiler includes a shell, a liquid reservoir defined within the shell to contain a first process fluid, and a tube bundle positioned within the liquid reservoir and at least partially submergible in the first process fluid, the tube bundle being configured to circulate a second process fluid that causes the first process fluid to boil and discharge a vapor-liquid mixture. A liquid-vapor separation assembly is positioned in the shell and includes a separation deck, and a plurality of separation devices mounted to the separation deck, each separation device being operable to de-entrain liquid from the vapor-liquid mixture and discharge a vapor. A vapor outlet nozzle is coupled to the shell to receive the vapor discharged from the plurality of separation devices.
