Installation
Algas-SDI Operation and Maintenance Manual – P/N – 54000
2-6
CAUTION
The entire installation must be leak tested prior to operating the
system.
NOTE
Do not connect this vaporizer to a storage tank that has been used
in vapor withdrawal service until the tank has been emptied and all
sediment and heavy ends have been cleaned from it.
LI
QUID INLET
NOTE
Do not install a check valve in the supply line between the tank and
the vaporizer. Liquid must be able to flow both ways in that line.
1. Ahead of the vaporizer inlet, install a 60-mesh strainer of equivalent size to
that of the vaporizer inlet connection.
2. Install a UL listed shut-off valve with a Minimum 250psi (17.24 bar) gas
pressure rating
3. The liquid line from the storage tank to the vaporizer should be of sufficient
size to supply the vaporizer at full capacity with a maximum pressure drop of
less than the hydrostatic head pressure (
see
NFPA 54
).
4. Connect the vaporizer to the storage tank.
L
IQUID SUPPLY LINE
(
see Figure
3
)
The liquid supply line should be adequately sized for the service.
