capabilities up to 1,000 DTs per hour, however, mostly the plant operates in a stand-by mode where
LNG Boil Off flow rates vary from 0 DTs per hour to 3 DTS per hour. The MAOP of the pipeline at the
odorizer is 60 PSIG, but can get as low as 30 PSIG. The existing odorizer is a Zeck Systems Model
Z9000 paired with a 250-gallon nitrogen blanketed odorant tank (which will remain in service).
Injection rate, odorizer status, alarms, and system battery voltage is sent back to GUC's LNG
SCADA system using a ControlWave Micro BSAP protocol.

- Validate Communications with GUC's SCADA system
Specifications for Equipment to be Provided:
Injection System
Can be either pump driven, or differential pressure driven injection system, has to be able to inject
up to 0.5 lbs of odorant per MMSCF at a maximum flow of 1 MMSCFH (1,000 DTs/Hr), and capable
of injection into pressures from 30 psi to 250 psi. Must be a closed loop system to purge and prime
back to the storage tank without exposure of odorant to the atmosphere. Enert gases can be made
available to the odorizer.
Pump Specifications if bidding a pump driven odorant system:
- Pneumatically actuated
- Approximate displacement of 0.325 cc/stroke.
