Corrosion is defined as the gradual decay of metals by electro-chemical reaction in its environment.
Why is Corrosion Control important?
The primary corrosive gasses found in electrical operation and control rooms are H2S, HF, HCl, Cl2, SOx, NOx, O3, NH3, Small quantities of these compounds, (only a few ppb) can create highly corrosive environments (ISA Standard 71.0).
Other factors such as temperature and humidity should be kept below specific levels to avoid creating conditions which are favourable to corrosion.
In an electrical or operating room with a corrosive environment complete anti-corrosion protection is only achievable through a combination of pressurisation and air recirculation in the room.
Positive pressurisation is the main way to ensure that uncontrolled and unclean air enters a protected area.
In addition, recirculated air must be treated to ensure total protection against corrosion, that is, to eliminate any contaminant that may accidentally enter the room, or that is generated within the room.
Corrosion Control Solutions
Bioconservacion offers a wide range of absorption methods for different contaminating gasses. These mediums are optimised to obtain high efficiency in short contact times and the use of smaller equipment reducing the quantity of granulates
Moreover, Bioconservacion offers various corrosion control methods, from coupons that collect corrosion data over a determined period of time, to automated corrosion meters that provide real-time data to control corrosion in a room or space. There’s also the option of analysis related to the remaining life span of the granules to predict when their useful life will expire, in order to ensure constant corrosion protection in the laboratory.
Bioconservation offers a full range of solutions to prevent and control corrosion processes.
