Altagas – Ridley Island LPG Export Terminal
Gas Liquids Engineering Ltd. (GLE) completed the Front End Engineering Design (FEED) of AltaGas’ proposed Ridley Island Propane Export Terminal. The planned facility will be the first LPG export facility on Canada’s Pacific Coast and provide access to overseas markets for propane producers in Western Canada.
The proposed location of the facility will be on sub-leased land from Ridley Terminals INC. (RTI) on Ridley Island, near Prince Rupert, BC and replace an existing sulphur facility on-site that was never commissioned. Pressurized liquid propane will be shipped to site in railcars via an existing CN rail network where it will be offloaded. The liquid propane will be chilled and stored in a large, 98,000 m3 atmospheric storage tank. Boil-off gas will be compressed, condensed, and recirculated in a refrigeration loop. An existing marine jetty will be upgraded with process lines and marine loading arms to load liquid propane onto Very Large Gas Carriers for transport to Asia and other markets.
GLE utilized in-house expertise for the process and facility design and engaged specialized engineering subcontractors to assist with design of the off-shore jetty upgrades, LPG storage tank design specification, and rail infrastructure upgrades.
The scheduled on-stream date for this facility is tentatively sometime in 2019. From detailed engineering to construction completion, the project duration is anticipated to be approximately 2 years.
