Abstract
Methods and systems described herein provide or use a wall structure for a hydrocarbon storage vessel. The wall structure includes an inner layer comprising a first rubber compound, a center layer comprising a fabric having a barrier layer applied to each side, and an outer layer comprising a second rubber compound.
Claims17
A wall structure for a hydrocarbon storage vessel, comprising:
- an inner layer comprising a first rubber compound;
- a first adhesive layer;
- a first vapor barrier layer in contact with a first side of a rubberized fabric,
- wherein the first adhesive layer is applied to the first vapor barrier layer and disposed between the first vapor barrier layer and the inner layer, and
- wherein the first vapor barrier layer comprises a nylon polymer coating of at least 0.51 mm thickness on the first side of the rubberized fabric;
- the rubberized fabric comprising a fabric treated with a rubberizing material;
- a second vapor barrier layer comprising a nylon polymer coating on a second-side of the rubberized fabric;
- a second adhesive layer;
- and
- an outer layer comprising a second rubber compound.
A fuel cell comprising a cured structure configured to store a hydrocarbon, wherein the structure is formed from a plurality of wall structures, wherein each wall structure comprises:
- an inner layer comprising a first rubber compound;
- an adhesive layer;
- a vapor barrier layer in contact with a first side of a rubberized fabric, wherein the adhesive layer is applied to the vapor barrier layer, disposed between the vapor barrier layer and the inner layer, and is in contact with the inner layer, and wherein the vapor barrier layer is a coating having a thickness of at least 0.51 mm;
- the rubberized fabric comprising a fabric treated with a rubberizing material;
- a second vapor barrier layer comprising a nylon polymer coating on a second side of the rubberized fabric;
- a second adhesive layer in contact with an outer layer, wherein the second adhesive layer is applied to the second vapor barrier layer and disposed between the second vapor barrier layer and the outer layer;
- and
- the outer layer comprising a second rubber compound, wherein the outer layer comprises an external surface of the fuel cell and does not comprise polyurethane.
