Can a round-block hole-type graphite heat exchanger be used under conditions of an operating pressure of 0.5 MPa? ? What other options are there? For heating, 0.5 MPA steam is used, and the medium to be heated is a dilute solution of hydrochloric acid or alkali
0.5MPa is no problem. Is it impervious graphite impregnated with phenol formaldehyde? This material is generally used for hydrochloric acid production; in the past, some heat exchangers in the chlor-alkali industry also utilized it. A pressure of 0.5 MPa is not a problem; the key issue is the poor heat exchange efficiency and weak impact resistance. Especially with steam, to prevent liquid slugging, it is easy for the pipes to develop cracks.
