SERVOMEX PROVIDES COMPLETE PTA SOLUTION TO CHINA
Servomex will supply a complete analyzer solution for the second phase development of Jiaxing Petrochemical Co Ltd ’ s purified terephthalic acid ( PTA ) production facility in Zhejiang province , China .
Four years after supplying a system for phase one of the project , Servomex was chosen to supply the plant with three SERVOTOUGH Oxy 1900 oxygen and three SERVOTOUGH SpectraExact 2500 toxic gas analyzers . These will be integrated into a bespoke analyzer house designed and built at Servomex ’ s Systems Integration facility at the company ’ s Asia Pacific Business Centre in Shanghai .
In a typical PTA process a mixture containing p-xylene , ethanoic acid , a catalyst system and compressed air is fed into a reactor , where a two-stage oxidation process creates PTA . As a result , precise , accurate and reliable monitoring and control of the oxidation reactions is critical .
The high reliability of the existing phase one system was a major factor in Servomex being selected for the next stage of the development , as well as Servomex ’ s low cost of ownership and long-term reliability in comparison to inferior competitor solutions .
In addition , Jiaxing Petrochemical Co Ltd was impressed by the quality of Servomex ’ s service offer , which will deliver fast , responsive maintenance and support from the Asia Pacific Business Centre .
Servomex is the leading supplier of PTA gas analysis solutions , with more than 30 projects having been fulfilled since 1995 .

“ Servomex is delighted to have been chosen for the next stage of this high-profile project , which shows great confidence in our system and the service and maintenance we offer . Both the analyzers they have chosen have strong track records in delivering accurate , stable results in the most challenging of environments . Jiaxing Petrochemical Co Ltd was further reassured to choose Servomex on the basis of numerous successful installations for other PTA plants , and confirmed that our current system is working well .”
By selecting Servomex ’ s award-winning SERVOTOUGH Oxy 1900 analyzer , Jiaxing Petrochemical is able to rely on the unique Paramagnetic oxygen sensor technology for accurate and stable measurements of oxygen . With a non-depleting measurement requiring minimal calibration , the Oxy 1900 was a compelling choice because of its optimization for hazardous applications including safety critical oxidation , long lifetime of ownership , and low maintenance costs .
The SERVOTOUGH SpectraExact 2500 analyzer is a rugged , highly-flexible multigas solution designed for a wide range of demanding process applications . It combines Gas Filter Correlation and Infrared technologies to deliver proven performance in the harshest process conditions , making it an ideal choice for the high-temperature , acidic environments encountered in PTA production . servomex . com / oxy1900 servomex . com / spectraexact2500
