Construction Dewatering for Oil Pipeline

TRANS MOUTAIN DELIVERS some 300,000 barrels of petroleum daily to the West Coast. The Trans Mountain Expansion aims to increase capacity and expand access to global markets.

‍

BACKGROUND:

An installation of 900 km of new pipeline greatly expanded the existing pipeline that measures 1,261 km across Alberta and British Columbia.

CHALLENGE:

Increased scrutiny and regulations: As the largest project in TMP’s history, the expansion required dredging, dewatering, and discharge to waterways and irrigation channels. Groundwater treatment was crucial to ensure released water was within regulatory specifications.

SOLUTION:

SimpleFloc, an anionic flocculant backed by the NanoNet platform, was recommended after bench tests. It was ideal for clarification, demonstrating enhanced flocculation, reduced active chemistry, and much lower toxicity.

• A simpler solution for complex operations: SimpleFloc is delivered ready to use, eliminating make-down, cutting chemical consumption, and reducing polymer by 80%.
• Benefits beyond cost: Not just cost-effective, SimpleFloc tackled DAF carry-over issues, reducing stress on the system and improved operator conditions, particularly in cold weather.

RESULTS:

“SimpleFloc was a game changer not only in helping our project operate within spec, but also in simplifying our overall process. It’s the difference between a system that just meets regulations and one that’s set up to accelerate and scale.”

Chemistry to compete

CarboNet’s NanoNet platform generates flocculants, coagulants, and targeting agents that that adjust in real time to changing wastewater conditions—cutting cost, dose rates, labor, and emissions.
