Pipeline De-Commissioning

Before any maintenance, product change, or decommissioning, it is essential to remove hydrocarbons from pipelines or process systems and render them in an inert state. The method for hydrocarbon removal depends on the specific properties of the hydrocarbons, such as:

• Type (oil or gas)
• Viscosity
• Chemical characteristics (sour, sweet, etc.)

SYGMA offers tailored hydrocarbon removal solutions, including:

• Nitrogen Purging – Safely displacing hydrocarbons with inert gas.
• Flushing – Cleaning pipelines using compatible fluids.
• Scraper-assisted De-oiling / De-gassing – Mechanical removal of residual oil and gas.
• Gel Pigging and Liquid Gel Solutions – Cleaning solutions for pipelines that cannot be pigged.

Surfactant Cleaning – Using chemical agents to remove persistent hydrocarbon deposits.
