All of the previous steps were within the confines of the starting aspect ratio. So, up to this point, hopefully we have an optimum design for that ratio. However, that ratio may not be optimum overall. So, ideally the entire process should be repeated over the range of aspect ratios that are not constrained by other factors, such as site restrictions and shop‐fabricated vs field‐fabricated issues. Only by doing this will we find the economically optimum design. The capex and opex of the agitator, vessel, and compressor should ideally be included.
