tions. " Our process and automation
engineering expertise, coupled with
our process automation system, will
provide the necessary tools to drive
success. By utilizing our multi-discipline
control platform to deliver an
integrated smart plant for Vadxx, it
will enable them to rapidly deploy
this technology globally. "
In development for over seven
years, the Vadxx process consists of
a series of standard unit operations
(heating, cleaning and cooling) in
a continuous, progressively zoned
system. There is no combustion occurring
in the system; rather, materials
are melted and boiled under
controlled environmental conditions.
The subsequent thermal decomposition
of these liquids results
in hydrocarbon vapors that are condensed
into the various products.
Upon commercial success at the
new plant, the next steps for Vadxx
will be to increase its breadth of
feedstocks to include post-consumer
waste, and to move the technology
closer to the materials' point of
generation to simplify transportation
and logistics. By expanding its
feedstock capabilities and moving
into post-consumer waste-processing,
Vadxx doesn't see its technology as
a competitor to traditional polyolefin
recyclers, more of an augmented or
complementary process, says Jeremy
DeBenedictis, vice president of
operations and engineering. Vadxx's
feedstocks are focused on difficultto-recycle
materials, including those
that are contaminated or off-specification,
which cannot be accepted by
conventional recycling processes.

Do you have flows up to
1,400 US GPM (320 m3
/hr),
heads up to 3,400 feet
(1,000 m), pressures up to
1,500 psig (100 bar),
temperatures from 20˚F to
300˚F (-30˚C to 149˚C), and
speeds up to 3,500 RPM? Then you need Carver Pump
RS Series muscle!
RS Series
Designed for moderate to high pressure pumping applications,
the RS is available in five basic sizes with overall performance to
1,000HP. As a standard, with a product lubricated radial sleeve
bearing and two matched angular contact ball bearings for thrust,
it only takes a mechanical seal on the low pressure, suction side
to seal the pump. Optional features include ball bearings on both
ends with an outboard mechanical seal, various seal flushing
arrange ments and bearing frame cooling. These features make
the RS ideally suited for Industrial and Process applications
including Pressure Boost Systems, Boiler Feed,
Reverse Osmosis, Desalination and Mine Dewatering.
Whatever your application, let us build
the muscle you need!
Creating Value.

Solving a PVC problem
Polyvinyl chloride (PVC) is notoriously
difficult for recyclers to process
when mixed with other materials.
According to guidelines
published by the Association of
Postconsumer Plastic Recyclers
(APR; Washington, D.C.; www.
plasticsrecycling.org), PVC is considered
to be a contaminant in facilities
that process typical plastic
bottles, such as those constructed
from polyethylene terephthalate
(PET) or high-density polyethylene
(HDPE) materials. And conversely,
the presence of PET (even in minute
amounts) can severely hinder some
PVC-recycling processes. Despite
some of the inherent challenges
in recycling PVC, VinylPlus (Brussels,
Belgium; www.vinylplus.eu), a
European organization consisting
of many vinyl producers and recyclers,
has set forth a goal among
its members to develop innovative
technologies that will result in the
recycling of 100,000 m.t./yr of PVC,
leading up to a target of 800,000
m.t./yr of PVC being recycled by
2020. Meeting recycling goals for
PVC and other waste materials is
crucial in Europe, where nine countries
have landfill bans in place.
