Marine Methanol Question

Cindy Zimmerman

I got a comment to a post that I would like to draw attention to because I can’t find the answer to his question myself. If anyone can help, please comment. Thanks.

I hope one of your readers can fill me in on a paticular aspect of fuel attributes. I operate a marine fuel dock in RI and I’ve recently learned we will be changing from MTBE to methanol in the next few months. I’m having difficulty finding an unambigious procedure to advise my customers on what precautions to use in order to avoid having phase seperation ( water )occure in their fuel storage tanks. They range from 6 gal to 250 gal. If ethanol is used, a simple water separator would be effective however the rumor around the docks is that if a supplier provides methanol as the additive the chemistry becomes more challenging to separate. My customers travel to offshore sites to fish and if problems develope out there it’s tough to stop in the breakdown lane. This saefty issue in marine fuels is the focus of my inquiry and I would appreciate any insight or remarks your readers would offer. Thank you for your time.
