Market leadership in Rotoform granulation — new orders
for sulphur and paraffin wax
With a number of major new orders confirmed over the last 18 months,
Sandvik Process Systems remains one of the leading suppliers of
chemical melt solidification systems to oil and gas producing customers
in the Middle East, with sulphur solidification being the primary
application.
Of the different solidification processes produced by Sandvik,
it is the company’s Rotoform system that has captured by far
the largest market, and 2002-03 has seen orders placed by prominent
engineering companies such as Technip, Snamprogetti, JGC, LG Engineering,
Petrofac and SK Engineering.
The Rotoform process, a combination of steel belt technology and
a specially developed drop-forming system, enables the cost-effective
production of free-flowing, dust-free and easy-to handle pastilles.
As well as supplying the Rotoform system itself, the company also
works in partnership with fellow Sandvik Materials Technology group
company, Roxon, to provide downstream handling equipment such as
conveyors, reclaimers and strip-loaders.
Since first introduced in the mid-1980s, over a thousand Rotoform
systems have been installed worldwide, of which more than 200 are
used for the solidification of sulphur. As more sulphur is extracted
from oil — and more companies need to convert liquid sulphur
into a solid product for easier handling, storage and transportation
– so the benefits of Sandvik’s pastillation system have
become ever more attractive to potential users.
Applications for the Rotoform process are not limited to sulphur;
the system is ideal for solidifying any of the by-products extracted
from crude oil, i.e. pitch, asphaltene, paraffin and residuals,
all of which can be solidified in an efficient, flexible and environmentally
friendly manner.
Orders recently confirmed for non-sulphur applications include
one from a customer in China who will use a new Rotoform plant —
consisting of four Rotoformers — to process up to 8t/h of
paraffin wax into free-flowing pastilles.
This system will be commissioned by the end of 2003.
