Glass fiber reinforced polymer liner for reinforced concrete molten sulfur storage tank

A method for storing molten sulfur, the method including:

• locating a reinforced concrete vessel under the earth's surface, the reinforced concrete vessel having:
• a floor that is a raft footing formed of reinforced concrete, the floor having a floor interior surface;
• a ceiling that is a slab of reinforced concrete, the ceiling having a ceiling interior surface;
• and
• sidewalls that extend between the floor and the ceiling that are formed of reinforced concrete, each sidewall having a sidewall interior surface, the floor, ceiling, and sidewall interior surfaces define vessel interior surfaces;
• and
• protecting the vessel interior surfaces from sulfur by,
• positioning a glass fiber sheet on the vessel interior surface, and
• embedding the glass fiber sheet in an epoxy vinyl ester resin after positioning the glass fiber sheet on the vessel interior surfaces to form a liner that is bonded to the vessel interior surfaces.
