Biomass supply and diesel requirements for co-feeding a bitumen upgrader in Alberta

摘要

1. A 3-stage biomass densification and hauling methodology has been proposed by 1.1 Splitting solid and liquid hauls 1.2 Applying square grid method for stage 1 and 2 and using geometric tool e.g. Google Map to calculate actual haulage for 3rd stage. 2. Model parameters need to be refined to reflect the local conditions at each district as well at harvest region, e.g. size of pyrolyser for each district C_(pyrolyser k), the efficiency of diesel consumption of trucks and tankers β, tortuosity factors (τ) for forestry and agriculture. 3. The model will evaluate the overall parasitic GHG emissions caused by hauling of biomass to upgraders. 4. The methodology will be used to optimize the output for multiple scenarios: 4.1 What will be impact of moisture content*, especially in the 1st stage of hauling? 4.2 What if we choose more than one upgrader of preference? 4.3 What degree of primary upgrading of bio-oil at the pyrolysis unit or at the district level is needed?
