The gas balance issue across the entire plant
Thread Content
Gas balance issues throughout the plant: 1. In the case of insufficient pressure, should propane or natural gas be used for supplementation? 2. Do gas pressure fluctuations become significant when switching towers in plants equipped with coking units?
It is better to use natural gas as a supplement, but in terms of efficiency it is not as good as using propane. However, propane and gas should not be used together; it would be better to have one burner that uses propane exclusively, while the others use natural gas
1. When the gas pressure is insufficient, supplement natural gas to control the pressure. For propane, when market conditions are favorable, we sell it; when conditions are not good, it is supplied separately for use in coking or as a raw material for hydrogen production, and it is never directly fed into the fuel gas network. 2. When switching coking towers, there are certain fluctuations in the fuel gas pipeline network; as long as these are properly managed and natural gas is supplied in a timely manner, no issues will arise. After all, the tasks are the same every day; finding a balance makes it easier to coordinate everything smoothly. 3. When using propane, it is still advisable to compare its price with that of natural gas; using propane in a rational manner can better demonstrate its economic value.
We use a mixed approach nowadays; when the pressure in the pipeline network is low, propane is added. As a result, the furnace temperature in each gas-using workshop experiences significant changes, since the calorific values of gas and propane are different
