Siemens to supply wastewater treatment systems for Sinopec refinery
Siemens has received an order from Sinopec Jiujiang Petrochemical Co. for the supply of a refinery wastewater treatment system that includes PACT biological treatment, Wet Air Regeneration and a Hydro-Clear filter system, and a Zimpro wet air oxidation (WAO) system for spent caustic treatment.
Siemens Energy has received an order from Sinopec Jiujiang Petrochemical
Co. for the supply
of a refinery wastewater treatment system that includes PACT
biological treatment, wet air regeneration (WAR) and a
hydro-clear filter system, and a Zimpro wet air oxidation
(WAO) system for spent caustic treatment.
Both of these systems are key
components in Jiujiang Petrochemical
's upgrade to meet
the new national discharge standards for wastewater and for
water re-use, according to Siemens officials.
The Jiujiang refinery
is located in the Jiangxi
province of China. Start-up is targeted for the end of 2014.
The PACT / WAR system will treat oily wastewater for reuse in
, enabling biological
treatment of wastewater using powdered activated carbon
. The system will also treat
salty wastewater from the refinery process to meet stringent
requirements for discharge into the Yangtze River.
The WAR unit provides for treatment of the activated carbon
used in the PACT process,
which is a biophysical wastewater treatment process. The WAR
unit simultaneously regenerates the spent carbon and destroys
the associated biological solids with a regenerated carbon
recovery rate of up to 95%,
helping to avoid expensive sludge dewatering and disposal.
The Zimpro WAO system will be used to destroy reactive
sulfides in the refinery
spent caustic, and to
break down complex phenolic compounds prior to final
wastewater polishing in the PACT system.
"Siemens is proud to partner with Sinopec in these environment
operations", said Mario Azar, CEO of the oil and gas
solutions business for Siemens Energy.
"The reliable and effective solutions provided by Siemens in
will help in their
efforts, especially in the sensitive Yangtze River area," he
added. "We look forward to further expansion
of our business in
China, a key market for our Water Solutions business."
