These cost categories are discussed in more detail in the following
sections.
In this study, the cost results are given in Canadian dollars, with
a base year of 2010. Other cost data quoted in the paper is given
with the base year used in the data source, unless otherwise indicated.
In the techno-economic model, cost data with different base
years has been scaled to the year 2010 using the Chemical Engineering
Plant Cost Index (CEPCI), which is provided monthly by
the journal Chemical Engineering [51]. The CEPCI is an index that
can be used to adjust costs from year to year based on changes
in labor cost, capital cost, and inflation [52]. Using the cost data
discussed in the following sections, techno-economic models for
HDRD production from canola oil and camelina oil were developed
using a discounted cash flow approach to determine the overall
cost of production for HDRD. Key assumptions used to develop
the techno-economic models are given in Table 5.
