The impact of mercury on aluminum heat exchangers
Thread Content
As the title suggests, the gas contains a small amount of mercury. Under what conditions can mercury cause corrosion to aluminum heat exchangers when it passes through them? For example, under what temperatures and pressures does corrosion occur? Thank you!
As long as they can gather. There is liquid mercury. Aluminum equipment is subject to corrosion regardless of temperature and pressure
It is sufficient to install a mercury removal unit; take a look: the natural gas mercury removal technology used in the Fushan oil field in Hainan involves adding a mercury removal tower to the pretreatment system. Activated carbon impregnated with sulfur is used to remove mercury from the gas, and after dehydration using a molecular sieve dryer, the gas enters the top of the mercury removal tower for further mercury removal. After the mercury removal unit was put into operation in March 2007, it performed well, with no mercury detected in the gas after removal. The demercurization agent used is one of our own productions.
