Smelting catalyzed smoke trains into "energy saving model"

As of early June, the continuous safe operation of Yanzhou Refinery Catalyzed-Cigarette Unit has exceeded 230 days. At the same time that it set a new record of continuous operation for 5 years, the cumulative energy recovered was 59.66 million kWh, equivalent to an economic benefit of 29.83 million yuan. System-wide advanced level.

The catalytic ash unit is one of the core equipments of the oil refinery equipment. The self-catalyzed equipment of the smelting unit has to be shut down and overhauled due to severe vibration exceeding the standard. Yanzhou Petrochemical has specially set up a QC team to implement technical research on the long-term operation of the smoke machine. After regularly monitoring the operating conditions of the smoke trains and locking up the main factors affecting the working conditions of the smoke machines, they broke through the routine and controlled the cooling steam volume of the wheel to control the wheel and vanes at a suitable temperature, thus eliminating production in a single move. There are problems.

At present, the vibration value of the catalyzed smoke machine gradually decreases from the previous 90μ to about 35μ. While ensuring the long-term safety production of the catalytic device, the recovery power of the smoke machine has also been greatly increased, reaching 11,350 kilowatts, and it has been successfully converted from an “electric tiger” to an “energy-saving model”.
