Although the bio-,oil, production cost as a function of plant capacity follows similar trend as shown in Figure 11, their estimated cost is higher than that shown in Figure 11 which could be due to the difference in assumptions and considerations (plant life, ash content, plant capacity factors, risk factors, feedstock ,price, increase, operating cost increase, yield reduction, total plant costs, etc) used in the calculation.

One, which produces an ,oil, called a ,CO 2, Select, uses lower pressure to liquefy the ,CO 2,. The resulting ,oil, contains only the source material’s volatile (aromatic) compounds. Some aromatic molecules are too heavy to be derived via steam, so the ,CO 2, Select oils may smell more intensely akin to the source material than ,oil, derived via steam, because more of the compounds are present in ,CO 2, ...
