A polyethylene unit experienced a gas leak within a high pressure tube and shell heat exchanger. Failure analysis revealed that the tube wall loss was beneath residual deposits. Preventative measures and improvements in inspection & cleaning procedures are discussed.
Establishment of criteria for the pilot-scale evaluation of the performance of cooling water additives under field-specific operating conditions.
In this paper the performance of a variety of biopolymers and synthetic polymers as calcium phosphate inhibitors is evaluated under a variety of cooling system impurities. For comparison various commercially available phosphonates were also investigated.
Increasing the life expectancy of cooling water equipment through the application of chemical conditioning techniques prior to cooling water exposure. Two steps: (1) cleaning of metal surfaces. (2) Protective film on the metal surfaces. Historical Document 1995
