Siemens to install wet air oxidation system in Qatar for ethylene expansion
The Zimpro wet air oxidation system from Siemens will be part of QAPCO’s facility in Mesaieed Industrial City. The new WAO system will provide QAPCO with more efficient wastewater treatment while eliminating noxious spent caustic sulfide odors. The facility should be operational in December 2013.

QAPCO is expanding its ethylene cracking unit from a current
capacity of 720,000 tpy to a new capacity of 900,000 tpy. The
Siemens scope of supply encompasses a Zimpro wet air oxidation
system as well as a complete power management system for this
The Siemens system will destroy odorous sulfide pollutants and
generate a biodegradable effluent that can be discharged to
conventional biological wastewater treatment, according to the
Siemens officials say that Zimpro wet air oxidation has been
widely accepted as the preferred technology for safe and reliable
treatment of spent caustic wastewater generated in ethylene
There have been nearly 40 systems installed for this
application over the past 20 years.
