  • Naphthenic acid corrosion inhibitors
    Patent number: 5182013
    Abstract: Naphthenic acid corrosion in refinery distillation units is inhibited by introducing into the units effective amounts of a polysulfide corrosion inhibitor.
    Type: Grant
    Filed: December 21, 1990
    Date of Patent: January 26, 1993
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Philip R. Petersen, Frederick P. Robbins, III, William G. Winston
  • Corrosion simulator useful for heat exchangers condensing vapors containing water and method for using same
    Patent number: 4599217
    Abstract: Apparatus for determining the corrosion rate of industrial condensing equipment so that corrosion inhibitors may be effectively utilized to control corrosion. The apparatus which simulates a cooling circuit for process streams which require the introduction of reagents to inhibit corrosion includes a primary condenser with automatic cooling control and more than one serially connected cooling-monitoring section, associated means for monitoring corrosion rate, temperature, and/or dewpoint and means for adjustibly controlling the process stream cooling rate of said cooling-monitoring sections. The process stream is flowed through said serial connected cooling-monitoring sections in order to cool the vapors in a manner which simulates cooling that will take place in a parallel connected heat exchanger unit.
