Methanol Storage and Delivery Apparatus for Gas Wells

Abstract

A gas well methanol storage and delivery apparatus, includes a housing forming an enclosed interior having a lower portion with a containment container therein having sealed bottom and sides, and an upper portion, and having at least one door to allow access to the interior. A storage tank mounting structure is adapted to mount a storage tank for storing a supply of methanol in the interior above the containment container sealed bottom. A pump mounting structure also in the interior of the housing is adapted to mount a pump for pumping methanol from the storage tank to a gas well for injection into the gas well. Vent means may be provided for allowing natural air flow through a portion of the containment container. The apparatus, with or without a tank and with or without a pump, may be supplied as a prefabricated unit to the well head site.
