Bio Heavy Fuel Oil, Technology mix, Production mix, at plant - LCI
The dataset represents the manufacture of Bio heavy fuel oil in Korea. It is based on the models created for the Korea EPD Energy database by Korea Environmental Industry & technology Insutiture(KEITI). The data is based on industry data supplied by companies which have representative technology and thus reflecting the realtity in Bio heavy fuel oil production. The foreground data have been combined with LCI models integrating Korea LCI dataset and Ecoinvnet 2.2 on energy supply systems, ancillary processes and materials as background data. Therefore, the data set covers all relevant process steps / technologies over the supply chain of the represented "cradle to gate" inventory.
The independent expert group in Korea, which is composed by KEITI, has critically reviewed the entire LCI data profile including data consolidation, development for the various LCI models and the calculation of the associated LCI data sets. null
Bio heavy fuel oil is a fuel manufactured from unused resources such as biodiesel by-products and animal and vegetable oils as raw materials, and it replaces heavy oil.
It is suitable for power generation because it has a lower flash point and higher calorific value than biodiesel for vehicles. It can replace heavy oil, contributes to the recycling of waste through its by-products from the biodiesel manufacturing process.
The bio heavy fuel oil production process is threefold: a pre-treatment process, a mixing process, and a storage process. And there are differences in each process depending on the raw materials used. The raw materials for bio heavy fuel oil are of lower quality than other biofuels such as biodiesel, and its pre-treatment process is flexibly operated according to the supply and demand of raw materials. There is no difference in the pre-treatment process itself except for the amount of input as it is a process of adjusting the concentration of acid according to the type of raw material. In the mixing process, auxiliary substances such as sulfuric acid and methanol are added to homogenize input raw materials and mix them with the pre-treated raw materials. The filtered mixed raw materials become a bio heavy fuel oil product which is finally transported to the tank terminal and stored.
The input include palm stearin(38.18%), bio diesel pitch(32.48%), palm olein(22.32%), palm oil(3.37%) and animal oil(3.37%) as raw material, water, methanol and dinitrogen gas as ancillary materials, and eletricity, steam, diesel and LNG as energy.
The output include Bio heavy fuel oil as product, wastewater and air emissions. Air emissions include CO2, CH4, N2O, CO, NOx, SOs, Particulates, PM10, NMVOC and NH3.
Korea dataset has been used for backgroud systems as follwings:

- Process water (2003), Kr
- Methanol production (2006), Kr
- Dinitrogen gas production (2006), Kr
- Electricity, Production mix (2000), Kr
- Steam production (2003), Kr
- Diesel production (2003), Kr
- LNG production (2013), Kr
- Ocean transportation_container ship (10,000~70,000dwt) (2007), Kr;
- Transport, freight, Cargo, 8ton ~ 10ton (2012), Kr;
- Wastewater treatment (2007), Kr
Ecoinvent 2.2 has been used for backgound systems as followings;
- palm oil, at oil mill
For palm stearin and palm olein, gate to gate data were referenced in the literature*, and eocinvent 2.2 dataset were intergrated.
