Since 1970, Linde has been successfully providing Wet Air Oxidation (WAO) technology, offering one-stop solutions extending from concept through to commissioning for spent caustic treatment plants. We offer everything from state-of-the-art design and engineering to supply of prefabricated skids and aftersales service.
We have dealt with virtually every kind of spent caustic stream generated in a refinery or a petrochemical complex and have developed an economical technology portfolio to treat this poisonous waste. This is complemented by additional units such as hydrocarbon stripper, oil removal and offgas disposal systems. These are combined on a case-by-case basis so that the final oxidized and neutralized effluent is suitable for discharge to a conventional biological treatment system.
In addition, we work with other contractors and licensees during early project development to finalize process schemes, concept layouts and utility requirements. This gives contractors and licensees early and valuable input into the key parameters needed to design downstream wastewater treatment facilities and ensure they are fit for purpose.
