DEFINITION

Classification: 376/366

Plural fluids or a fluid in plural phases circulating within reactor (e.g., pressure tube reactor):

(under subclass 361) Subject matter involving the circulation within a reactor (e.g., pressure tube reactor) of at least two fluid streams which may differ from each other in chemical composition or physical state, e.g., water and steam, water and molten metal, or hydrocarbon.

(1) Note. For a pressure tube reactor to issue in this or indented subclasses, a first fluid must be circulating through the pressure tubes with a second fluid being present or circulating outside of the tube through which the first fluid circulates.

(2) Note. For single fluid pressure tube reactors, search this class (376), subclass 401.
