Equipment recycling

Some automobile manufactuieis have found the in-shop recycling equipment to be ill-advised one service bulletin warns of the deterioration of engine-coolant ethylene glycol to the extent that no additive can restore it to an acceptable state (21). 

Does the Toller use a primary ozone depleting compound (ODC, for example, a CFC or 1,1,1, -trichloroethane) m their process Are ODC management practices followed (for example no uncontrolled releases of ODCs, installation of capture and recycle equipment, leak detection and repair, use of well trained personnel) ... 

Since these reactions are also strongly endothermic, the reactor must be heated, and this is usually accomplished by piping the fluid into a furnace in interstage heating, where it is heated back to the desired temperature and returned back to the reactor. In a catalytic reforming process, the furnace and the catalyst recycle equipment are frequently larger than the actual reactor. 

Such approaches sometimes represent a distinct risk for the contractor in such models, since misuse of a user can hardly be excluded without giving the user the impression that the service has been curtailed. A clear separation of responsibilities, ownership, operation, maintenance, etc., in the individual processes helps to avoid dissatisfaction. Service models should target at an almost complete takeover of responsibility not only for the chemical, but also for the application plant and the waste management or recycling equipment. 

As an example for a high level service model the so called "Total Care Model" may serve, where the supplier owns the application and the recycling equipment and is responsible for its operation and maintenance, although the plant is situated at the user s premises (Fig. 2). 

Unfortunately, you have to pay for all the reactant fed to a process, not just the fraction that reacts, and any A that leaves with the product therefore represents wasted resources. Suppose, however, you could find a way to separate most or all of the unconsumed reactant from the product stream. You could then sell the resulting relatively pure product and recycle the unconsumed reactant back to the reactor. You would, of course, have to pay for the separation and recycle equipment, but you would compensate for this cost by having to purchase less fresh reactant and being able to sell the purified product at a higher price. 

The cost of the reactor that would be required to achieve an 83.3% conversion in a single pass could be much greater than the cost of the separation and recycle equipment. 

For these experiments, a portion of the solvent was introduced slowly into the recycle vapor line. Samples were taken after the solvent had distributed itself throughout the polymerizer, devolatilizer, and recycle equipment. No solvent was added to the feed monomer, although for long periods of operation a small amount of solvent would normally be required in the feed to make up for solvent lost through the extruder as part of the volatile in the copolymer product and also, possibly, lost through the condenser into the vacuum system. 

There are several reasons for building a second pipeline first, valuable recycle flows can be efficiently transported to downstream users who would not mind the variable ratio and concentration of inert gases. Thereby, in upstream industrial processes the need for recycle equipment ceases to exist. The upstream producers could generate some income by selling their recycle flows. 

Because of the heterogeneous nature of the mixture, and presence of contaminants, the articles produced should have large cross-sections, so that small imperfections do not hinder the mechanical performance of the products. Products can be manufactured by continuous extrusion, compression molding, or by Klobbie-based intrusion processes. Intrusion process is a cross between conventional injection molding and extrusion. In this, the extruder first works and softens the thermoplastic mixture, which is poured into one of the molds without using screen packs or nozzles. Today s recycling equipments are capable of processing most types of mixed thermoplastic material, even with up to 30 to 40 percent contamination as unmelted polymers or nonpolymer materials such... 

This book summarizes information on plastics recycling based on studies conducted for the state of Illinois. Part I discusses characterization, collection, costs, and markets for mixed plastics recycling. Part li discusses recycling technologies, Including those for processing and separation, buyer specifications, and the manufacture of plastic lumber. Appendices Include lists of scrap plastic handlers and brokers, manufacturers of recycling equipment, and information sources. 

Finally, it would be useful to cite the Annual Buyer s Guide to Tire and Rubber Recycling Equipment [66], which contains contact details and brief product information for more than a hundred companies, most North American, including manufacturers of primary and secondary tire shredding eqnipment, knives, and granulating and pulverizing systems.
