Mechanism of Mercury Corrosion and Technology of Mercury Removal of 5083 Aluminum Alloy Heat-exchanger

Mercury is a natural composition existing in natural gas.When the environment temperature is below -40 ℃,mercury is in liquid form and could cause serious corrosion of the heat-exchanger with aluminum alloy plate fin in gas gathering system.Reference for mercury corrosion of aluminum alloy was put forward by analyzing the corrosion example of the mercury corrosion of the heat-exchange equipment in Yakela gas gathering plant,understanding the corrosion mechanism,comparing and selecting the process of mercury removal technology and evaluating the effectiveness of mercury removal.
