PPM – Energie aus nachwachsenden Rohstoffen GmbH ( PPM - energy from renewable resources Ltd. ), founded in 1999 in Austria, has developed an innovative technology for the production of fatty acid methyl esters (biodiesel) from fresh vegetable oils, used vegetable cooking oils and animal fat and manufactures new production plants on the basis of this technology.
PPM also plans, constructs and starts biogas plants for a wide range of substrates for mesophilic or thermophilic operation in accordance with their own technology developed in Asperhofen and Berlin.
Fatty acid methyl esters (FAME) from virgin vegetable oil, used vegetable oil or animal fat are called biodiesel.
100 per cent FAME (fatty acid methyl esters) can be used as fuel. On the German and Austrian market, this fuel is obtainable under the name of ”biodiesel”.
Biodiesel = 100 per cent FAME ( fatty acid methyl esters )
PPM offers modules for the production of biodiesel with capacities from 5000 to 50000 tones per year.
These capacities are optimal for economic reasons as well as for ecological reasons:
The PPM biodiesel technology is based on the approved process of trans-esterfication of fatty acid glycerides in an alkaline environment. Liquid prefabricated potassium methylate is added as catalyst.
The actual process is preceded by the pre-cleaning of the raw material. The pre-cleaning contains the filtration, drying and reduction of the share of free fatty acids in the oil.
The actual process consists of 4 main stages:
The soapy water, accrued during the reaction, is added to the glycerol phase.
Consumption data per ton of produced biodiesel:
|virgin rape oil||1020 kg|
|potassium methylate||35 kg|
The quality of the produced biodiesel corresponds to the European standard EN 14214.
The PPM biodiesel technology has the following advantages:
