Ethylene and Chemical Plants

World-class spent caustic treatment solutions

We’re a world-leader in the treatment of ethylene spent caustic. Our hydrothermal treatment solutions, including Zimpro® wet air oxidation (WAO), electro-oxidation (ZEO) and catalytic gasification (ZimCat); and wet air regeneration are backed by decades of process and application knowledge.

Next Generation Spent Caustic Treatment

Learn more about Zimpro® WAO followed by advanced biological polishing treatment and the advantages over alternative technologies, expected effluent quality, and use of this technology to increase fresh water recovery.

Spent Caustic from Ethylene Production 

Spent caustic from ethylene production is characterized as a toxic and odorous wastewater, primarily due to its high sulfide content. Consequently, treatment can be a challenge. For more than 25 years, Siemens has addressed this challenge using Zimpro® wet air oxidation (WAO) technology as pretreatment for biological polishing. Siemens has developed a method for directly treating spent caustic to avoid contamination of the remainder of the wastewater with its high dissolved solids content. 

Downstream Refining and Petrochemicals

From discharge to reuse, we have your solution

Advances in technology and an evolving regulatory environment, coupled with increasing production and operational demands pose new challenges for a variety of industries. Let us help you find the right treatment solution for wastewater discharge/reuse and process water treatment, in addition to high-strength wastewater treatment.

Upstream Oil and Gas Production

Solutions for upstream operations

Contact us today for offshore and onshore produced water treatment for discharge or reuse. We offer decades of produced water treatment experience applying our corrugated plate separators and solid/liquid or liquid/liquid hydrocyclones for primary treatment; dissolved air/gas flotation with our Brise™ pump and Spinsep™, Veirsep™ and Combosep™ systems for secondary treatment; and tertiary treatment using our Monosep™ walnut shell filter and PerforMedia™ oil removal media.
