The onshore Gas Receiving Facility is located at Cove Eco Estate and Business Parkland, adjacent to the T&TEC Power Plant.
It was designed to operate with two (2) independent processing trains each with a capacity of 100 million cubic feet of gas per day (mmcfd) and a metering system for measuring the gas volumes sold. It has a minimum capacity of 12 mmcfd and a maximum of 200 mmcfd with the second processing train installed.
At present only one processing train has been installed and therefore the facility’s current processing capacity is 100 mmcfd.
This Gas Receiving Facility boasts of a ground flare, the first of its kind in the country. There is, therefore, no visible or open flame and no smoke emanating from the flare. This feature is consistent with Tobago’s theme of Clean, Green, Safe and Serene.
All storm water will be first collected in the storm drain sump for removal of any hydrocarbons. Water produced during the processing operations will be collected separately and treated in the Produced Water Treatment unit to ensure it complies with the EMA water effluent standards before release into the environment.
For safety purposes, there are (i) an Automated Process Control System (11) an Automatic Emergency Shutdown System (iii)) a Standby Generator to handle 100% of the Plant load (iv) automatic fire and gas detection systems (v) firewater and foam systems (vi) a PA/Emergency alarm system and (vii) an odourizer to inject an odorant into the gas before it is sold to customers on the Industrial Estate. The odorant‘s pungent smell will allow for easy and quick detection of any gas leaks.
The Condensate ( hydrocarbon liquids) removed from the gas stream is stabilized, collected and stored in two storage tanks (2,800 barrels each) with bund walls or barriers around the tanks as a secondary barrier to prevent leakage of the contents into the environment. Currently the Company is considering two options for disposal of the condensate: The primary option is sale of condensate to a third party on the island for use in asphalt manufacturing operations. The other option is to transport the condensate via cargo vessel back to Trinidad for sale to Petrotrin.
A sophisticated Programmable Logic Control (PLC) system will monitor and control in real time all process operations at the facility.
During operations the facility will be manned by a team of cross functional technicians working on a 12 hour continuous shift basis.
The plant is equipped with Closed Circuit Television (CCTV) monitoring.
