Article Synopsis
- The global sulfur limit regulation requires 0.5% low sulfur fuel oil (LSFO) to cut down harmful emissions, but adding naphthalene (Nap) to stabilize LSFO has increased polycyclic aromatic hydrocarbons (PAHs), mainly from Nap.
- A study analyzed exhaust from 16 ships and found Nap emissions made up 77% to 97% of total volatile organic compounds (VOCs), with levels exceeding 50,000 μg/m in fishing vessels, tankers, and harbor crafts.
- The rise in Nap emissions worsens air quality in port cities and poses health risks, suggesting the need for better emission controls or alternative stabilizers for LSFO to minimize these negative effects.
This study presents the real-time energy consumption of a container ship's generator engine on two round-trips from the West Coast of the US to the East Asian ports and analyzes the ship's PM, PM, NO, SO, CO, and HC emissions, shore power usage, and factors affecting energy consumption. The average total energy consumption and air emissions for the two round trips were 1.72 GWh and 42.
