Abstract: | The continuous development of new crops for anaerobic digestion has led to the need to manage in a rational and environmentalfriendly way the distribution of the digested products that comes out of the biogas plant. The EU, national, and regional regulations set the time windows when it is allowed to carry out the slurry applications and the limits on the amount of Nitrogen per hectare (ha) to be distributed in the field. The purpose of the study was to compare the use of traditional tanker system [TS] vs. the umbilical system [US] in terms of application performance and operation costs. Based on the field trials carried out in 2008 2009 and 2010 a dynamic, discreteevent simulation model using Extendsim® software (Imaginethat Inc, USA) was built. The values of the input parameters are based on experimentally measured and subsequently analyzed data. The assessment considers the following factors: field distance (1 to 5 km, step 1 km) and rates of Nitrogen distributed per ha (50 to 300 kgN ha1, step 50 kgNha1). The US was shown to be costeffective for high application rates and distances of 24 km. The US allowed, however, a very important reduction in working time (up to 71% for a 5 km pipeline system) compared with the TS. The significant savings in term of working times (up to 400 h/y savings for 1 MW biogas plant) are a useful information in terms of comprehensive planning involving, for example, timeliness issues and/or workability issues. The US allows covering a larger area within the available operational days compared to TS. The savings for the distribution of the digestate, on selected scenarios, was found to be about 40% for the US (up to 20,000 €/y). Assuming a 15 years lifetime for a biogas plant, this implies savings up to 0,3 M€, and a significant reduction in the associated energy expenses and CO2 emissions. |
