The industry automation division at Siemens will equip the
Reficar refinery in Cartagena, Colombia, with an integrated
water treatment solution, the company announced on
The deal is worth over $30 million, the company said, and
will form the heart of a combined system for treating both
process and waste water.
Siemens technologies will be applied to prepare river water
for use as boiler feed water, and to purify wastewater before
discharge, for example.
It is part of a project to expand and modernize the
refinery, which is scheduled to be
completed in the first half of 2013.
Siemens says it will supply a multi-component solution for
treating the process water in the Reficar refinery.
These include contact basins for softening the water and a
J-Press filter press for thickening the accumulated primary
Siemens will also provide plants for desalinating the boiler
feed water and treating waste lye. The condensate is to be
cleaned with granular, active charcoal filters.
The wastewater from the refinery will also be purified by a
multi-stage system. To start with, API (American Petroleum
Institute) separators and DGF (dissolved gas flotation) systems
will separate the oil from the water.
An Omniflo sequencing batch reactor will handle the
biological purification before the Hydro-Clear sand filter
employs gravitational filtration in the tertiary stage.
Centrifuges will be used to dewater the sludge.
The expansion project will not only double the
capacity of the refinery to 165,000 bpd, but also
produce better quality, low-sulfur fuel. This will improve the
fulfillment of national and international environmental directives.
