Gas Liquids Engineering Ltd. (GLE) completed the Front End Engineering Design (FEED) of AltaGas’ Ridley Island Propane Export Terminal. The facility was the first LPG export facility on Canada’s Pacific Coast and provides access to overseas markets for propane producers in Western Canada.
The location of the facility is on sub-leased land from Ridley Terminals INC. (RTI) on Ridley Island, near Prince Rupert, BC and replaces an existing sulphur facility on-site that was never commissioned. Pressurized liquid propane is shipped to site in railcars via an existing CN rail network where it is offloaded. The liquid propane is chilled and stored in a large, 98,000 m3 atmospheric storage tank. Boil-off gas is compressed, condensed, and recirculated in a refrigeration loop. An existing marine jetty was upgraded with process lines and marine loading arms to load liquid propane onto Very Large Gas Carriers (VLGC’s) 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 facility was onstream in 2019. From detailed engineering to construction completion, the project duration was approximately 2 years.
