Bio-fuel technology simulation

In the current era, growing environmental awareness supported by international treaties and followed by governments created the need for manufacturing fuels from renewable sources. Three types of the most promising "bio-fuels" are:

"Bio"-ethanol, "Bio"-gas ", "Bio" diesel

Nor-Par has expertise in building tailor-made software and modelling of different bio-fuel technologies. We provide tailor-made software and solutions based on the requirements and data from the client, and we calibrate the software and models together with the client. CHEMCAD/CC-DYNAMICS are used as the Engine for these solutions. We have reference companies and Universities. Do not hesitate ask us for details.


Ethanol can be made from virtually any natural material that can be converted to saccharides (sugars). The most economically promising sources of the raw material are:

Each of the routes has own specifics that may include these steps

Examples of applications that Nor-Par works with:

Membrane Separation Technology Unit by Nor-Par/Nor-Par Online A/S

After the fermentation, it is necessary to separate ethanol from water and waste-products of fermentation. To produce fuel-grade ethanol it is necessary to dehydrate it that requires more complex technology (making dry ethanol requires passing so-called "azeotrope point"). First stage typically consist of conventional distillation unit. while conventional azeotropic distillation with entrainer used to be applied for the dehydration in the past. Nowadays, the market follows the new route of ethanol dehydration, which is membrane technology (pervaporation). With membrane technology, you can use 11 times less energy compared to the conventional dehydration process.

Nor-Par/Nor-Par Online A/S has developed specialized Membrane Technology simulation unit that uses CHEMCAD as the Engine. Each membrane brand has different physical properties and separation strength. Nor-Par serves expertise in the field to help you simulating process including the membranes you have. We are backed up by a pilot plant for material property testing

Processing fermentation waste-products

Fermentation yields waste-products called "fusel oil" consisting mostly of amyl alcohol. It is possible to convert the fusel oil into organic acids and also produce esters of the amyl alcohol and organic acids. Esters serve as valuable solvents in many industries. Nor-Par can help you with simulation of the processes converting fusel oil into valuable products. CHEMCAD is the simulation tool for that.


Bio-gas can be derived by fermentation of natural material, but also can be produced by pyrolysis or gasification of various organic material such as wood, lignin, waste of the pulp industry or from communal waste. After being produced, bio-gas requires thorough cleaning before it can be commercially used. Bio-gas can also be converted into liquid fuels.

Nor-Par can help you design or optimise bio-gas production facility. We use CHEMCAD/CC-DYNAMICS as the Engine for our tailor-made software and solutions. Do not hesitate to ask us.

Bio-diesel and other liquid bio-fuels

One of proposed ways of producing liquid bio-fuels is Fischer-Tropsch synthesis from bio-gas (Gas-To-Liquid technology). Another route of bio-diesel manufacture is transesterification of vegetable oil with methanol.

If you research any of these routes, be aware that Nor-Par can help you with our tailor made software and solutions in this field.

Chemstations and Nor-Par

Chemstations Inc based in Houston TX , USA are the owners and makers of the CHEMCAD Suite of process simulation software.

Oslo-based Nor-Par a.s is exclusive distributor of CHEMCAD Suite in Scandinavia, East Europe and Russia . Nor-Par a.s and its daughter company Nor-Par Online A/S also provide own software and solutions to fill the gap between standard process simulation software and unique needs of the market as well as unique needs from a specific client.
