I think glycerin melts/freezes around 62 degrees
SpillPro drum skimmers have aluminium frames, which are lightweight for easy transport and handling. Their rotating drum is made from high density polyethylene, making them resistant to impact and abrasion.
A pneumatic or hydraulic power source turns the drum. Oil sticks to its surface and is scraped off into a collection trough. The same power source pumps the recovered oil to a collection tank onshore, or on vessel.

I imagine that putting an old baseboard heater inside a pipe wouldn't work; the airflow wouldn't work out properly.
