Corrosion Process Simulator

A method of corrosion monitoring comprising:

• weighing a test coupon to determine a first weight;
• inserting the test coupon into a flow path defined by a body, wherein one or more sealing elements are disposed between the test coupon and the body;
• flowing a fluid from an inlet of the body, through the flow path, and to an outlet of the body such that the fluid contacts the test coupon;
• flowing current through the test coupon while flowing the fluid to heat the test coupon;
• and
• thereafter, weighing the test coupon to determine a second weight.

A system comprising:

• a corrosion monitoring apparatus comprising:
• a body defining a flow path;
• an inlet to the flow path;
• an outlet to the flow path;
• a test coupon at least partially disposed within the flow path;
• a sealing element disposed between the test coupon and the body;
• and
• a current source electrically coupled to the test coupon,
• wherein the inlet and the outlet are in fluid communication through the flow path, wherein the sealing element electrically insulates the body and the test coupon,
• wherein the current source supplies current to the test coupon, and
• wherein the current source comprises control circuitry capable of varying current supplied to the test coupon;
• and
• a control system configured to provide a control signal to the current source.
