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.

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.

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.

Straightforward reaction expands ability to recycle strong, lightweight materials used in applications such as wind turbines ...

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 ...
