The system will be supplied by the Water Technologies division of Siemens' Industrial Solutions and Services (I&S) Group.
Using WAO technology will help the plant alleviate two problems frequently associated with ethylene spent caustic: disposal and odor. The technology destroys odorous sulfides and allows acid neutralization of the spent caustic, and discharge to conventional biological treatment.
"Zimpro(r) wet air oxidation technology is commonly selected in new ethylene facilities for treating spent caustic," says Rob Lawson, director of industrial sales for Siemens Water Technologies, in Rothschild, Wis. "We now have dozens of operating units treating ethylene spent caustic. This is a clean and effective treatment process that fits well into ethylene plant operations. The Olefins-2 project will be our first in Kuwait."
The 850,000 m.t./year Olefins-2 ethylene plant is scheduled to be completed in mid 2008.
