Minimizing corrosion is of paramount importance in most plants involved with chemicals production or refining oil products. In a new online guide METTLER TOLEDO discusses the role in-line analytics can play in keeping corrosion under control in (petro) chemical plants and refineries as well as in power and cogeneration facilities.
Annual costs of corrosion have been estimated at 3 trillion USD globally, of which approximately 25 % can be attributed to process industries and power utilities. It is not just the repair or replacement of damaged equipment that is expensive: Significant amounts of money are lost on subsequent production downtime, environmental damage, and health and safety hazards.
External measures such as painting, coating, and cathodic protection may offer satisfactory measures in sustaining integrity of engineering structures, but protecting the inside of process equipment requires a different approach. Constructing an entire plant from corrosion resistant, exotic materials usually involves an exorbitant initial cost. Therefore, corrosion protection programs are usually based on chemical treatment. The effectiveness of specialty chemicals very much depends on process conditions, and as these may vary, so will the quality of the treatment. To be on the safe side, expensive overdosing of corrosion inhibitors has therefore become the rule rather than exception.
Monitoring and controlling pH, conductivity, dissolved oxygen, sodium, and silica can go a long way to keep corrosion at bay, and can significantly reduce use of reagents.
In METTLER TOLEDO's online guide, "In-line Analytical Measurements for Corrosion Prevention in Chemical Plants and Refineries", the company shows through case studies and white papers how modern in-line and on-line process analytical solutions can be utilized to minimize corrosion and its effects.
