Fisher®Design ES Valve Eliminates Leaks
In Hydrogen-to-Flare Application

RESULTS

•An $8,000 valve saves $800,000 USD per year through
improved shutoff.

•The valve eliminated the leak by using a match plug and
seat, with extra seat load. It was tested by measuring
downstream temperature. (Hydrogen heats up after a
large pressure drop).

•The Fisher
valve, provided control (on average) better than 1%,
and paid for itself in 3.8 days.

Pressure control valve to high-pressure flare.

CUSTOMER

An oil refinery in Texas.

CHALLENGE

A two-inch, 600# globe valve was leaking hydrogen directly to the flare.

iguring the price of hydrogen at $2200 per MMSCF, any leak was costly.

se, the leakage (>1 MMSCFD) represented more than

ydrogen leakage rate was a minimum of 1 MMSCFD (41,667 SCFH).

g in the valve and comparing production verified the leakage. At

at time, the price of hydrogen was between $1800 and $3200 per

SCF. An Operations Support Engineer (OSE) advised the team to use

r MMSCF for the average hydrogen cost to justify this

vestment.

SOLUTION

Jim Pfeil (account manager) and Craig Jeane (valve asset manager) of
Puffer-Sweiven, Emerson Process Management's local business
partner in Houston, Texas, used the cost of the lost hydrogen to
justify the valve replacement. They recommended a new Fisher
valve with Class V shutoff, a Type 667 size 46 actuator, and a

fieldbus digital valve controller with Advanced Diagnostics
(AD) capabilities. Per these specifications, Emerson's Fisher valve
division supplied a two-inch Design ES valve, which was installed
during a turnaround.

Two years later, this pressure control valve is still providing tight, leak­free operation. No maintenance has been required to date.
