Conclusions

It is of critical importance to ethylene plant operators that their fired heaters are
running optimally as even the lightest of fouling has a substantial impact on performance, given the high proportion of operating costs made up by energy consumption and
heating requirements.
Traditional and often antiquated cleaning methods are limited in their ability to remove
fouling from finned or studded convection banks within fired heaters. The majority can only
clean ca. 2% of the entire tube bundle heat transfer surface area and fail to remove the more
compact and tenacious deposits.
Robotic fired heater convection section cleaning as developed by Tube Tech
offers a unique and superior solution, delivering proven energy and financial savings in situations where conventional methods have struggled or failed and at a superior net present value.
