Abstract

1,132,014. Cooling systems. IMPERIAL CHEMICAL INDUSTRIES Ltd. 22 April, 1966 [4 May, 1965], No. 18730/65. Heading F4U. [Also in Division C7] To prevent stress corrosion cracking of a stainless steel heat-exchanger, the coolant, e.g. water, is circulated at such a pressure that bubbles are prevented from forming. The coolant may contain a corrosion inhibitor, e.g. trisodium phosphate, and dissolved gas and impurities are removed. Operation of the exchanger may be prevented, until the coolant is at the desired pressure. The heat-exchanger may be used to cool a reaction vessel and the coolant may be circulated by pumping or convection.
