Case Study of electrical room corrosion: Palos de la Frontera (Huelva) Plant

CEPSA continues to trust in Bioconservacion solutions for electrical room corrosion's prevention.

In CEPSA's different refineries we have already installed equipment to regulate corrosion and pressurisation in electrical rooms. We recently published an article on this subject on our blog; Safety, Protection against Corrosion and Cabinet Pressurisation in Refineries.

On this occasion CEPSA's chemical plant in Palos de la Frontera (Huelva, Spain) was the facility that needed an efficient solution to manage corrosion in its control rooms.

The main activity of this plant centres on two product lines: on the one hand, cumene, phenol, acetone and alphamethylstyrene that are basic commodities in construction and the automotive industry, and on the other, methylamines and its derivates for a wide variety of applications such as weedkillers, fungicides and insecticides, solvents, fine chemicals and pharmaceuticals.

To prevent corrosion of the electrical equipment in the Palos plant, two SAH systems (Lateral access and horizontal flow system) have been installed, loaded with filtration media in PP12 modules. These systems promote air flow, achieving an optimisation of filtration media, and facilitate the replacement of these media when they are worn out.

The filtration media that Bioconservacion has recommended in order to efficiently remove corrosive gases present in the air are Bi-On OXYL and Bi-On ISORB. Both ensure an efficient reduction of a broad range of pollutants such as acid gases, SO2 and low-molecular-weight compounds that can generate corrosion issues.

As on previous occasions, Bioconservacion offers a service of analysing coupons and analysing the remaining life of filtration media to check that the proposed solution is functioning correctly, and to ensure that media are replaced at the right moment.
