Title:
METHOD AND APPARATUS FOR PURIFYING FUEL OIL
Document Type and Number:
WIPO Patent Application WO/2008/032604
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a method and apparatus for purifying a fuel oil in which
maintenance work is facilitated and purification effect can be enhanced significantly
by capturing impurity particles in the fuel oil. [MEANS FOR SOLVING PROBLEMS]
A plate rotary electrode (21) is provided in a container earth electrode (20),
and a voltage application means (3) is provided for applying a DC voltage between
the electrodes (20, 21) in order to make impurity particles in a circulatihg fuel
oil cohere and coarsen by making the Zeta-potential of the impurity particles
lower or disappear and to charge the impurity particles with a potential reverse
to that of the plate rotary electrode (21) so that they are attracted to the opposite
side faces (21a) thereof by Coulomb force. Furthermore, a scraper (22) for scraping
and collecting the impurity particles attracted to the opposite side faces (21a)
of the plate rotary electrode (21) is provided. A fuel oil processed by a purifier
(1) is purified to such an extent that the residual carbon is 8-9 wt% or less and
the impurity particle diameter is 5-10 μm or less.
