Raw materials recycled

These processes are aH characterized by low isobutane conversion to achieve high isobutylene selectivity. The catalytic processes operate at conversions of 45—55% for isobutane. The Coastal process also operates at 45—55% isobutane conversion to minimize the production of light ends. This results in significant raw material recycle rates and imposing product separation sections. 

Can the process be operated at less severe conditions If this results in lower yield or conversion, can raw material recycle compensate for this loss ... 

THERMAL METHODS OF RAW MATERIALS RECYCLING OF PLASTICS WASTES... 

The stream discharged from a process step may consist of a mixture of product and unconverted raw material, which must be separated and the unchanged raw material recycled to the reaction zone for further processing. 

No in-process contact water is currently used by the latex rubber industry. No raw material recycling is practised because of poor control of monomer feeds and the buildup of impurities in the water. 

Mater-Bi . [Novamont N. Am.] Thermoplastic horn natural, renewable raw materials recyclable, combustible, and biodegradable plastic for pkg. films, bags, 6-pack yokes, disposable diapers, hospital and sanitary prods. 

Raw material recycling goes back to the chemical base units of the polymers, which are reused, for example in polymer synthesis, production of other chemical... 

In essentially the same plant it is possible to produce a wide variety of NPK products simply by adding additional raw materials. Recycle ratios of 1.5 - 2 may be achieved in NPK production. Depending on the product, the additional raw materials may be solid or liquid. For solids, appropriately sized material (< 2 mm) is added to the recycle system liquid material is fed directly into the granulator. 

Considering the preservation or saving of the material, the material recycling is the most effective procedure. The usable fractions are about 70 to 80 % [6]. Also raw-material recycling processes achieve an output of 70 up to 80 %, exceptional the pyrolysis of mixed plastics waste. Hydrogenation of a clean... 

Energetical utilization, i.e. direct incineration of plastics waste has the disadvantage of the higher environmental impact in comparison to the incineration of oil or gas from raw-material recycling processes. Every step to higher environmental compatibility of incineration decreases its energetical usability and is coupled with an appropriate increase of costs. 

For thermoformed parts, the cost of the final part is the complex sum of the raw materials recycle incorporation, conversion efficiency, and others. To this end, the resin design used conventional resins and fillers to minimize the raw material cost.
