CASE STUDY
THE PROJECT
A gas analysis solution was required by a major petrochemical company based in the Middle East . The company required a combustion control system at its polymer plant furnace in order to achieve its efficiency and environmental goals .
THE CHALLENGE
The end-user has operated an ethylene plant for more than 20 years , and was in the process of upgrading the 14 dual-fired furnaces on its cracker units to improve efficiency and safety .
Oxygen measurements were being made using Zirconia sensing technology , which became less accurate and unreliable over time due to clogging , so more fuel had to be spent to control the combustion process .
The company is committed to using innovative technology to operate sustainably and minimize its impact on the environment , so it was necessary for the gas analysis solution to comply with this goal as well as achieving accurate measurements within the process .
It was looking to Servomex to supply an alternative technology that was non-contact , accurate , fast , and reliable .
THE SERVOMEX SOLUTION
Servomex has delivered 56 analyzers and purge panels as part of this upgrade project . The analyzers are SERVOTOUGH Laser 3 Plus Combustion instruments , with half configured to measure oxygen and the rest measuring carbon monoxide .
The Laser 3 Plus analyzers support the customer ’ s environmental objectives by helping to provide better control of the cracking process – improving efficiency , reducing emissions , and limiting pollution .
Using non-contact , non-depleting Tunable Diode Laser sensing technology , they deliver fast and accurate measurements of the specified gas . Unlike single-point analysis techniques , they are installed across the stack , providing an average measurement which is much more effective for safety monitoring .
By measuring both oxygen and carbon monoxide ( CO ), they allow the combustion reaction to be optimized , increasing efficiency . Accurate CO breakthrough analysis , delivered quickly , helps control the amount of fuel spend on combustion , reducing consumption and increasing savings . The more efficient reaction also reduces the emissions generated by the process .
Installation and commissioning took place in 2020 and the gas analysis systems are now undergoing final testing prior to completion and handover . The client has already recommended the Laser 3 Plus analyzer for use in its future projects .
