Abstract
The described invention relates to a method for determining corrosion in wet gas pipelines comprising: a) using a portion of the liquid phase from a wet gas pipeline; b) placing said portion in a high pressure, high temperature autoclave to prepare a saturated vapor phase; c) transferring the saturated vapor to a corrosion test unit, said unit having a specimen holder section having external, temperature adjustable means, and specimens being arranged in one or more positions within the specimen holder; d) chilling said specimen holder section so as to cause condensation onto said corrosion testing specimens; and, e) calculating a value selected from the group consisting of corrosions rate, pitting of the specimen, weight loss of the specimen, and any combination thereof. The invention process can be practiced in a separate laboratory apparatus designed to accomplish the above method, or in a similar online apparatus set up in a semi-batch mode or continuous mode.
