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. The monitoring means which include corrosion and temperature probes and dew point measuring units provide monitoring means to determine corrosion rates at the various temperature levels of the hydrocarbons so that a corrosion profile can be established and related to the temperature of the vapors at various locations in the heat exchange units of the equipment.
