was with men of your training perhaps you wondered whether you'd be working for chemical engineer maybe you can see how a mechanical engineer would get very far in a chemical company that's why we want to show you something of what goes on  supervise manufacturing let's consider the opportunities available to you here is research and development your special interest or machine design maybe you're the kind of a follow more for that research and development some of the work is done here at the experimental station i'm accountable engineer in this field develops mechanisms used in making the company's product is work may result in a massive piece of equipment like this are in a delicate and like this one there's never been a shortage of problems for research and development engineers they run into the thousands actually they mainly do original equipment to meet new and specific needs to improvement of machines already in operation let's look at a few examples they have huge compressors are used in making your carbon dioxide on ammonia out high temperature and pressure ammonia problems like this kind of lever about one hundred times a day at these high pressures machine where alignment and assembly are extremely important tolerances are severely narrowed pains to avoid stress concentration such as might occur in sharp transitions that corner policy action of the high pressures cause a rapid fatigue of material and give rise to many design problems that falls directly in the mechanical engineers lab now here's a machine used in the plastics industry it's called an extractor extruder it melts plastic takes the solvent from it and explodes it in one operation while to adapt dupont plastics or to scale it up or down and called for studies in power requirements heat transfer and fluid flow in other cases engineers often design and develop equipment for use by dupont customers here are two young engineers working to improve a machine that simultaneously farm and then expand the cube or plastic material or i'll make it into a project that requires work at super pressure here's a field that's really challenging and young to behind us deal and concrete barricade equipment can be tested at pressures far beyond the unit in manufacturing today after a string gauges have been attached to the test and the pressure lines connected a mirror is placed so about an engineer can observe the results of the test through a periscope on the other side of the barricades that will come a time when the pressure is far beyond those of today will  twenty thirty forty thousand pounds per square inch these men are getting ready for the time when pressure is even higher than this may become part of industrial practice development many mechanical problems had to be solved before nylon was produced successfully and the naturally mechanical engineers had a big part in solving them just how would you go about melting nylon chips that several hundred degrees fahrenheit without a little of the composition as possible while mechanical engineers designed then tried quite a few types of melting grit some of them didn't work as well as others but they finally came up with a grin that did the job mechanical engineers designed a precision but it works under pressure is better than a thousand pounds per square inch but not before they like the problems of gas getting sealing and material the heart melted nylon solidifies into filaments as it is pumped through holes in the spin around that are almost too tiny to see naturally that spin around isn't a standard item either had to be designed my arm fibers  certainly found it so let's move on to this petroleum laboratory because they are another important part of the development work activity devoted to improving existing processes and products their engineers are matter of fact control instruments they are practically all must on nearly every phase of manufacturing operation because they have come to mean so much in terms of sleeping and economy take a look at this maze of pipes for  maximum production yields reacting chemicals must be brought together under conditions as nearly ideal as possible all steps in the process must be smoothly coordinated actually some processes of the day couldn't operate with instruments of ten years ago it's a fast moving intensely interesting field if this kind of work appeals to you whether you're tackling from the plant design and or from the development and instrumentation offers tremendous opportunities still another field for mechanical engineers at the poncas plant engineering this is a fairly broad field including maintenance and power it also includes design and construction on sub major projects that may involve process improvement or planned expansion nearly all chemical manufacturing operations must run in mechanical equipment tanks gavels valves and this equipment gets heavy use much of it on a seven days a week basis it's bound to wear out and that means maintenance part of maintenance is keeping equipment in top mechanical shape catching trouble before it catches you supervising this work here again is a supervisory job or alert engineers helping with the maintenance work of the machine shop that many dupont plant the needs of some of these shops are always changing that means an almost continuous program of mechanical study ranging from layout and scheduling to working up shop standards now let's say your major interest is power power is essential in a chemical plant as it is in any other kind and the power problems that arise from ponds complex operations are about as challenging as can be found anywhere our engineers at dupont must supply a steam electricity water air refrigeration and other services under a variety of conditions look at this being reducing stations it is one of several operating at various pressure differentials they supply steam at the right pressures and temperatures over a wide range of capacities from one thousand to twenty thousand pounds per hour in a short period of time while their feed water pumps compression distilling almost all power plant equipment needs plenty of engineering know how to avoid interruption in these essential services production supervision is another major activity at that time for engineers would like to work with people but still want to put their technical training to good use the duties are broad and cover all phases of plan operation on the job might well include setting up a vision maintenance schedule for equipment keeping production rolling maintaining quality reducing waste and at the same time building employee morale quality production as determined by individual workers each must understand the importance of his job and it's up to the production supervisors to develop his understanding mechanical engineers and others that would dance in this work for a wage role and professional employees and manufacturing process and the use of the equipment and in responsibility they also work with development engineers in plant technical sections and the central engineering department here their knowledge of the manufacturing process is used in working out designs for process improvement or new plan in all cases the planning and conduct of a continuing program of training and working practices is an important part of supervisory work raw materials scheduling quality standards of intermediates and finished product handling employee suggestions all are part of the work in production supervision the mechanical development laboratory is evidence to how important mechanical engineering is at the principal activity of the laboratory is to develop and build a full scale automatic machine to be used as models for those in manufacture the woman to the shops are still further evidence they make special equipment and machines for company use they are among the most completely equipped in the country and it's all top notch equipment ranging from small bench lathe to large diameter boring machine noticed that this radio drill press has built into it or deep drilling but you have to use a microscope to get a good look at the hole and drill yeah so mechanical engine there has quite a bit about ballroom around here with all this equipment to serve knowledge you have an idea of what does go on in a chemical company you can see that instead of no opportunities a mechanical engineer has many opportunities to use his abilities in training and in many fields because dupont and manufacturing departments operate to a large extent as ten separate companies the way a man heads towards his goal varies from department to department you might start off working with a man who has many years of practical experience you collect material assemble data make calculation you may attend a formal training program that includes conferences on leadership procedures employee relations company policy and safety in either case you have every opportunity to get a broad picture of the company as well as to learn your job regardless of which way you go you'll find a vast sources of information for you or you find libraries with technical literature over one hundred engineering consultants within the company each an expert with years of experience metallurgy stress analysis our location instrumentation even meteorology there is a never ending need for better machine better ways to do new things to meet the challenges of the research and development design and construction production supervision and all phases of plant engineering you to meet these talented mechanical engineers work with each
