Clyvia presents energy balance for conversion of polymers into fuel oil and diesel
Wegberg. - Clyvia Technology GmbH has prepared a comprehensive energy balance for the mineral fuels produced from polymer waste. The calculations were similar to the previously prepared balance for waste oil conversion and led to similar positive results. The company made this announcement at its corporate headquarters in Wegberg-Wildenrath.
Contrary to waste oils, polymers such as polyethylene and polypropylene must first be preheated to 300 degrees Celsius using an extruder, before they can be processed into fuel oil or diesel. For this reason an additional 65 kWh is required– over and above the base load of 25 kWh electrical energy to power pumps, scrabbers and other system functions – to power the electric motors of the extruder. This increases the total electric energy required to 90 kWh.
The other parameters are generally identical to the waste oil results. An input of 500 kg per hour yields 450 kg mineral fuels, of which 50 kg serve as combustion energy for the reactor. According to the balance, 400 kg saleable material remains, which corresponds to a utilization of 80 percent. Add to this 25 kg fuel gases, which also help to heat the burner as well as 25 kg bitumen, which can be used in road construction later.
A sensational bargain: The finished product costs 25 Euro Cent per litre
Even without including the gases the energy efficiency of the process is 85 percent. “However, if you add the gases,” according to Dr. Manfred Sappok, one of two managing directors at Clyvia Technology GmbH, “the value should be around 90 percent. Thus we achieve excellent numbers for waste oil as well as polymers, which last but not least are reflected in a bargain price per litre, which in both cases is approximately 25 Euro Cents.”
The process developed by Clyvia is based on fractional depolymerization, which is similar to cracking crude oil. With a process temperature of 400 degrees Celsius – significantly less than traditional cracking such as pyrolysis – long hydrocarbon chains are cracked, which then evaporate and condensate in a distillation column as diesel oil.
This technology is attractive for private and public waste management enterprises as well as for industrial and manufacturing firms, which would like obtain energy from their organic waste materials such as waste oil, scavenge oil, packaging waste or production waste, which otherwise would involve expensive disposal.
