There’s a device that has just been put into operation. Do you know what kind of device this is? On December 24th, after four months of intensive construction work, the project to address the exhaust gas issues at the silos of Yanshan Petrochemical’s high-pressure polyethylene plant was successfully completed. The RTO system was ignited successfully on that day at 17:57, marking the timely completion of this key safety hazard remediation project of Sinopec level. This project is also one of the initiatives under the Blue Sky Defense Campaign supervised by the Beijing municipal government; its core component is the construction of a new RTO furnace with a design processing capacity of 38,000 standard cubic meters per hour. The RTO furnace is known in Chinese as a regenerative thermal incinerator. Its working principle involves heating organic waste gases to over 760 degrees Celsius, which causes the VOCs in those gases to be oxidized and decomposed into carbon dioxide and water. This not only prevents air pollution but also eliminates potential safety hazards. The exhaust gases from the metering systems of the 3 production lines, as well as those from the blending silos and the finished product silos in the Yanshan Petrochemical high-pressure polyethylene plant, can all be directed to an RTO furnace for purification. It is reported that the device was put into use to handle exhaust gases on the 28th.
