What are the similarities and differences between biochemical engineering and chemical engineering?

Reply 1# ytuking: Biological engineering and chemical engineering have both similarities and differences. The similarity is that in the industrial production of biological products, there is also a need for the transfer of materials, heat energy, and mechanical energy; in other words, the processes such as analysis and purification that take place in the downstream processing stages are similar. The difference is that for our biological products, the reaction conditions such as temperature, pH, and pressure are not as strictly controlled as in chemical production; generally, these conditions are at room temperature and normal pressure. Moreover, a major difference between biological production and chemical engineering is the necessity for strict aseptic production; it can be said that any contamination could lead to complete failure. Therefore, many designs in the product production process take this into account. Moreover, biological products are defined by their biological activity; therefore, it is essential to pay close attention to this aspect during the separation and purification of such products!
