Electrostatic charge dissipator for storage tanks

A liquid storage tank, comprising:

• a) an electrically non-conductive interior surface;
• b) tank walls enclosing an interior volume;
• c) a bracket attached to the tank, inside the tank;
• d) an electrical feedthrough for providing an electrical conduction path between tank interior and tank exterior;
• e) at least one electrically-conductive polymeric fiber yarn electrically connected to the feedthrough and mechanically attached to the bracket and hanging from the bracket inside the tank, wherein the at least one conductive fiber yarn is exposed and has at least 10 broken fiber tips or stray fibers per linear foot of the dissipator projecting from the at least one conductive fiber yarn.

An electrostatic charge dissipator for collecting and removing electrostatic charge from inside a tank, comprising:

• a) a mounting bracket for attachment to the tank inside the tank;
• b) a support with a first end attached to the bracket, and a second end;
• c) an electrical feedthrough for providing an electrical conduction path between tank interior and tank exterior;
• d) a braided sleeve comprising electrically-conductive polymeric fiber yarns electrically connected to the feedthrough, wherein the braided sleeve surrounds the support and is exposed and has at least 10 broken fiber tips or stray fibers per linear foot of the dissipator projecting from the braided sleeve.
