Engineering factors in chemical processes
Thread Content
Let’s discuss: What engineering factors exist in chemical processes, and how do they affect product production?
It depends on what device it is. In the oil refining industry, factors such as temperature, pressure, feed volume, product volume, and steam volume are all very important.
Engineering factors? Should it mainly focus on mass and heat transfer aspects, such as mixing, flow, and so on?
If we’re talking only about engineering factors, the ones I encounter here include: the selection of vacuum pumps – which affects the level of vacuum and thus the main content of the product; the heating design of the synthesis reactor – which influences the speed and extent of the reaction, and consequently the main content of the product; the selection of agitators for the crystallization reactor – which has a direct impact on the crystallization process; and the design of the heating source circulation – which affects the heating efficiency in various areas and is directly related to product quality
Put simply, it’s the issue of the three transmissions. In more detail, they refer to the various problems related to heat, mass, and momentum transfer that arise during engineering or industrial production processes.
Thank you all for participating. I think what was said on floor 6 is quite appropriate; it would be even better if it were more specific!
Not only must the amplification effect be taken into account, but more importantly, the influence of environmental conditions must also be considered, such as the lagging effects of changes in temperature and pressure
I also think that it’s often a matter of mass transfer. For example, in reactors, chemical engineers have to consider not only kinetics (the area of study for chemists) but also the transfer of mass, heat, and momentum (such as external and internal diffusion). In distillation columns, fluid dynamics must also be taken into account (for instance, how fluids are distributed).
I feel the same! Therefore, engineering factors are very important in chemical development; often, certain products can be produced successfully in pilot tests, but fail to be manufactured even in pilot-scale trials, and these issues are all related to the engineering factors we need to take into consideration!
Personally, I feel that the amplification effect is the most significant factor; the various phenomena that occur in the pattern of three passes and one counter-attack are likely also manifestations of this amplification effect. Another influencing factor should be the issue of industrial interference.
This is no small issue at all – it encompasses all three types of transfer along with their reversals. In short, it’s about considering the delays or deviations in heat, momentum, and mass transfer, and their impact on the responses”； There are many details to consider, for example: could the local high concentrations resulting from the addition of materials have any impact on the reaction? In the case of an exothermic reaction, could insufficient stirring lead to localized overheating due to delayed heat dissipation? An inappropriate mixing pattern can result in poor efficiency of the mass transfer process, thereby affecting the reaction time or yield……
