In fertilizer WWTP, what protection system should be used for Methanol storage tank,precautions,measures and the type/degree of instruments, IP class?

Methanol’s strength is in its chemical makeup. Known as “wood alcohol,” methanol is a simple molecule (CH3OH) that serves as a carbon source for bacterial “bugs.” Accelerated by the addition of methanol, anaerobic bacteria rapidly convert the nitrate to harmless nitrogen gas, which is vented into the atmosphere. The advantages of methanol in the denitrification process are copious. As it contains no solids, no additional nutrients, has a neutral pH, is low cost and contains 100% readily degradable substrate, methanol offers the ideal solution to nitrogen reduction both in its ease of use and in its positive impact. Methanol can be made from anything that is or ever was a plant including biomass, natural gas, forest thinnings, agricultural waste, landfill gas, and even carbon dioxide captured from the atmosphere. This ‘poly-generation’ means that ultimately methanol can be produced from a number of renewable feedstocks and waste streams, especially those that are local to the wastewater plant adding to its overall sustainable impact.
