Phase-Two Water Detector

Phase Separation Detection

What is Phase SeparationFull Phase Separation: Classic Definition

> Any time water enters a tank of ethanol-blended gasoline, some of it binds to ethanol and stays suspended

> Continues until saturation, then ethanol-water mixture falls to bottom of tank Phase Separation

> A half-full 10’ 10k gallon tank with 20 gallons of water will lead to 5” of PS

Partial Phase Separation: More Common Occurrence

> The water that does not stay suspended falls to the bottom, pulling ethanol with it you never have pure water at the tank bottom

> Occurs far more often than full phase separation; needs much less water

> Can still cause same damage as full phase separation

If you get water in a tank of ethanol-blended gasoline, you will get phase separation

Effects of Phase Separation

Older tanks are only

compatible to E10 PS is E75-E80 PS leads to tank corrosion

Damage to existing equipment

Left undetected, Phase Separation can corrode your tanks, your customers’ engines, and your profits

Damage to customer vehicles and brand

PS damages cars’ engines Liability with station owner Unhappy customers talk

Early detection> No cars have been affected> No lines have been affected

Remedy> May be automatically resolved with

another delivery of fuel> Pump out a couple inches of PS from bottom of tank to sweeten load

Implications> Lost fuel ($300)> Service contractor ($300)> Lost business ($0)

Current Detection Methods3. Automatic Tank Gauge

Description

Water float sensor on electronic probe detects level of water in tank

Drawbacks

Density of phase separation may be too low to raise water float, making PS undetectable

Existing detection methods are either unreliable or detect too late

“Good”

“Bad”

1. Sticking tank with paste

Description

• Put paste on a long stick and insert into tank

• If paste changes color, indication of potential problem

Drawbacks

• Do not stick tank regularly

• Difficult to follow consistent procedure

• Difficult to interpret results

2. Dispenser Fuel Filter

Description

• Use dispenser filter specially designed for phase separation

Drawbacks

• Only detects PS at dispenser, not in tank remediation costs are higher

• More frequent filter changes adds additional cost

• Lack of use / awareness
