Chemical manufacturing processes unit operations concept

Thus, microreactor technology, by allowing continuous processes, touches at the heart of fine chemical manufacturing processes, namely it reduces the amount of labor required to run a process. It reduces the amount of labor because it reduces the number of unit operations (or procedures) accomplished by workers. Those operations are performed in situ through an automated system and an appropriate microreactor setup (toolbox concept). The relation between continuous operations and labor is well established in other industries such as the petroleum industry, leading to highly automated and efficient processes. 

Process Technology 3—Operations—combines process systems into operational processes with emphasis on operations under various conditions. Topics include typical duties of an operator. Instruction focuses on the principles of modem manufacturing technology and process equipment. Emphasizes scale-up from laboratory bench to pilot unit. Describe unit operation concepts solve elementary chemical mass/energy balance problems interpret analytical data and apply distillation and fluid flow principles. The purpose of this class is to provide adult learners with the opportunity to work in a self-directed work team, operate a complex operational system, collect and analyze data, start and stop process equipment, follow and write operational procedures. The course is advanced and requires the learner to apply classroom skills to real-life operational activities. Students are required to qualify and operate a process unit. 

The manufacture of even simple devices may entail more than 100 individual steps. However, many of the same concepts and procedures are invoked several times. Therefore, it is advantageous to group the process steps broadly in terms of unit operations analogous to those used successfully to conceptualize, analyze, design, and operate complex chemical plants involving a similarly large number of chemical processes and materials. Examples of these unit operations are listed in Table 1. 

After the veneer has been properly unitized and dried, it is transported to the gluing operation. It is here that the greatest proportion of chemicals other than water are involved in the plywood process. To better understand the adhesive resins involved, perhaps it is best to review the quantities of softwood and hardwood plywood manufactured in relation to the adhesive needs required. The 1972 - 1973 era were years of peak production in the United States for plywood. Data will be extracted from various reports for presentation purposes. Hardwood and softwood plywood production is normally reported in different manners and it is difficult to compare. While the values reported are not intended to be exactly accurate, they will give some comparison, relatively speaking, and should give some concept of the volume of plywood produced and in turn the volume of adhesives used.
