Oleum Vent Systems
For General Industry
    MECS, Inc. offers a fully engineered package system for controlling SO3/H2SO4 emissions from oleum storage tanks, tank trucks, railcars, and loading stations. These units are available in flows from 100 to 1,500 cfm. The units hydrolyze SO3 vapor into sulfuric acid mist and use a high efficiency Brink Mist Eliminator to remove the mist. Typically, customers with a storage tank vent problem will require a 100 cfm package. If there are multiple vent problems, such as several storage tanks at high rates, a 200, 500, or larger cfm package will be required.
    Where an oleum loading or unloading dock is involved, the package size is governed by the hood design, but a typical package would require a 200 or 500 cfm oleum vent package.
