What don't you understand?
http://www.reachoutmichigan.org/fune...k/plastic.html Petroleum to Plastics The technological road from oil field to finished plastic product has numerous fascinating side trips. Here’s the route taken in the petroleum-to-plastics process: 1. Petroleum is drilled and transported to a refinery. 2. Crude oil and natural gas are refined into ethane, propane, hundreds of other petrochemical products and, of course, fuel for your car. 3. Ethane and propane are "cracked" into ethylene and propylene, using high-temperature furnaces. 4. Catalyst is combined with ethylene or propylene in a reactor, resulting in "fluff," a powdered material (polymer) resembling laundry detergent. 5. Fluff is combined with additives in a continuous blender. 6. Polymer is fed to an extruder where it is melted. 7. Melted plastic is cooled then fed to a pelletizer that cuts the product into small pellets. 8. Pellets are shipped to customers. 9. Customers manufacture plastic products by using processes such as extrusion, injection molding, blow molding, etc. |
