At concentrations of 0.1 and 0.01 moles in 0.1-molar acid, their presence reduces the corrosion rate by between 50% and 90%, which implies at least a doubling of component lifetime.

Combating sulphuric acid corrosion at wastewater plants ... "MICC often corrodes the conventional types of concrete used in wastewater treatment plants at a rate of a centimetre or more per year.

The cold end acid corrosion problem was addressed by the use of a shallow (12″) layer of heavy gauge (18ga) Cor-Ten steel element designed for ease of cleaning (Figure 1).

Reduction of unit heat rate and increased corrosion of downstream equipment due to the raising of dew point by SO 3. Fouling of air heaters and SCR catalysts due to the reaction of SO 3 with ammonia.

Background. CO 2 corrosion, also known as "sweet corrosion", is a common and harmful form of corrosion in the oil and gas industry. It occurs when CO 2 dissolves in water, forming carbonic acid (H ...

Using numerical modeling, an Italian research team has discovered the role 'macrocells' play in the corrosion of hollow submerged marine concrete structures such as tunnels and parking structures.
