Abstract

Portable/transportable apparatuses, methods, and systems for generating and delivering sulfur trioxide on-site or near an item to be treated is provided. A method for extracting hydrocarbons from deposits containing a clathrate hydrate such as methane hydrates includes a step of delivering sulfur trioxide to an ice deposit containing a clathrate hydrate and subsequently extracting linear or branched hydrocarbons.
