What type of odorant blends can be used in evaporative systems?
Single component odorants, e.g., THT, or blends where components have similar vapor pressures, e.g., all mercaptan blends or blends with TBM and MES, can be used in evaporative systems. Do not use mercaptan/DMS or mercaptan/THT blends. The components in these blends have widely differing vapor pressures, which results in inconsistent odorization of your gas.
