Recovery of products esp. oil unsuitable for pumping - by injecting hot water and extracting products with the aqueous phase

摘要

A system for the recovery of products which are difficult to recover by pumping, i.e. the recovery of mineral oil from the tanks of sunken tankers or of fuel oil from the bunkers of sunken motorships, introduces hot water in the form of piercing and stirring jets to frm an aqueous phase in the upper part. The product is dispersed in this aqueous phase and extracted with it. The system removes the risk of pollution of the sea and of the coastline by oil contained in sunken ships. It is effective when the hydrocarbons have a high viscosity which would make it impossible to pump them.
