Use condensate water or hot water from the system’s circulation to replace steam for winter heating ； Advantages: 1. It can significantly reduce steam consumption for refineries that face a shortage of steam in winter ； Disadvantages: 1. The heating effect of condensed water in extremely cold areas is likely to be poor ； II. Replacing the steam-heated hot water used in the polypropylene production process with condensate water can save steam ； III. The heating source for the oil storage tanks has been changed to circulating hot water from the plant, thereby saving steam ； IV. Using condensate to replace part of the demineralized water in the deaerator ； Advantages: It can reduce water consumption for chemical preparation ； Disadvantages: Condensate may contain oil, leading to oil contamination in deoxygenated water and oil-contaminated steam ； V. Install propane vaporizers to reduce fuel gas consumption (applicable to refineries that cannot meet their operational needs with the dry gas produced on-site and thus require additional natural gas) ； Advantage: It is possible to adjust the amount of natural gas or propane used based on market conditions (the prices of natural gas and propane), thereby reducing production costs ； Disadvantage: Burning propane may affect the heating performance of the furnace ； Petroleum Chemical Zone – “Creative Ideas for Energy Saving” event: http://bbs.hcbbs.com/thread-1666758-1-1.html Xiaomi phones are waiting for you to claim them
It’s a type of energy recovery, and we are also using it.
OP, I have a question: Is a propane vaporizer a heated heat exchanger installed in front of the fuel gas nozzle in a heating furnace?
Our propane vaporizer is installed in the coking unit; the outlet pipeline of the propane vaporizer is connected to the outlet pipeline of the gas separation tank in the coking feed heater, where it enters the heater along with the gas to be burned.
It’s a type of energy recovery system that we have been using for some time already; thanks for sharing :)
Some of these measures can significantly reduce energy consumption, and there is data to support this; thanks to the original poster for sharing
Once, the frequency of backwashing the filter in gasoline hydrogenation was adjusted depending on the purity of the oil; the backwashing interval was changed from once every 4 hours to once every 32 hours； The pressure zoning control at the top of the feed oil tank in the hydrogenation unit has been changed to allow only air intake and no air outlet. Reduce fuel gas consumption ；
