In chemical production, how are the calculation parameters for many formulas obtained? Pray to the deity
Thread Content
In chemical production, many formulas are needed to calculate parameters such as flow rate and volume. However, many formulas that represent practical problems involve a large number of variables, and the coefficients and constants in these formulas are often very difficult to find; it’s not possible to measure them in a factory right away. Is there any place/website where such information can be found directly? The deviation from the ideal state equation is also extremely large; it makes me miss my school days, when *each problem came with standard coefficients, and one could just apply the formulas to get the answer! For example, with PV=nRT for propylene, the calculated actual volume deviation is too large; how can this be resolved? ? ? First, I’d like to thank all the experts out there! ! !
Regarding the actual production conditions on site, what should be focused on is the actual condition of the equipment, whether it is operating at its maximum capacity, and whether it meets the design specifications. For statistics related purely to computation, it is impossible to simply apply the data provided in books. For example, most instrument readings are now digital, but there is still a measurement accuracy issue. If the precision is not sufficient, errors will occur in the calculations. The price of instruments is often related to their precision; it’s not possible to determine it solely through calculations, as shown in books. The calculation can only be done by assessing whether the design capability requirements are met. If the requirements are not met, it is necessary to coordinate with the design manufacturer to find a solution. For a company’s production calculations, it is best to conduct overall accounting by using the locations of various points such as electricity meters for power supply, feeding scales, and external measurement parameters; internal calculations should also be refined as much as possible using this same method.
