The high efficiency STHE technology used in our 2MMTA DHT unit allows us to use the fired heater only during the startup phases. During normal operations, the STHE is so efficient that the furnace can be shut down, saving dramatically the consumption of f​

The existing combined feed heat exchanger of our 2.2 MMTA reforming unit has been replaced with a designed and manufactured ZPJE's Spiral Tube Heat Exchanger in July 2020.​

The combined feed and effluent heat exchanger of our 2.4 MMTA CCR unit was replaced in November 2019 with a spiral tube heat exchanger (STHE) designed and manufactured by ZPJE.​

Feed and effluent heat exchangers in 3.2 MMTA CCR unit, 3.2 MMTA disproportionation unit and 3.6 MMTA isomerization unit were replaced in October 2017 with spiral tube heat exchangers (STHEs) designed and manufactured by ZPJE.​

The feed/effluent heat exchanger of the reactor of our 0.6MMTA PDH unit was replaced with the STHE designed and manufactured by ZPJE in August 2017.​
