Title:
WASTE PLASTIC CRACKING APPARATUS AND METHOD OF CRACKING WASTE PLASTIC
Document Type and Number:
WIPO Patent Application WO/2008/108282
Kind Code:
A1
Abstract:
A technology for absorbing chloro-compounds generated at the cracking of waste
plastic. There is disclosed a waste plastic cracking apparatus having a cylindrical
container (110) surrounded by a heat insulating material (200). Waste plastic
is fed into the container (110) from a first hopper (120). The container (110)
can be heated by a burner (220), and the waste plastic is converted in the container
(110) to a liquid phase component and further to a vapor phase component. The
vapor phase component is recovered from either a first outlet duct (116) or a second
outlet duct (144). The liquid phase component generated in the container (110)
is regulated not to rise beyond dashed line X. The space extending over the upside
of the liquid phase component is provided with a perforated delivery pipe (140)
adapted to have an absorbent for chlorine absorption, fed from a second hopper
(150), delivered through the interior thereof. The chlorine contained in the
vapor phase component is brought into contact with the absorbent delivered through
the interior of the delivery pipe (140) and absorbed thereby.
