Abstract
Systems and methods for preventing biocorrosion of fuel handling components located in a sump in a fuel dispensing environment. One method includes exposing a hygroscopic material to moisture-laden air in the sump such that the hygroscopic material deliquesces into a liquid solution and exposing a buffer material to ethanol-blended fuel vapors in the sump. The method also includes collecting the liquid solution in a reservoir and monitoring the level of the liquid solution in the reservoir using a liquid level sensor. Further, the method includes notifying service personnel of the level of the liquid solution in the reservoir.
Claims16
A system for use in a fuel dispensing environment sump, the system comprising:
- fuel piping extending from at least one storage tank to at least one fuel dispenser;
- fuel handling equipment in fluid communication with the fuel piping, the fuel handling equipment at least partially enclosed by the sump;
- a hygroscopic material disposed in and exposed to air in the sump, the sump comprising a reservoir disposed beneath the hygroscopic material;
- and
- a buffer material having a pH greater than 7, the buffer material disposed in and exposed to air in the sump.
