The demand for diesel is growing at twice the rate of gasoline, which has been declining greatly in the U.S. and is expected to continue declining as drivers shift to more fuel-efficient vehicles. In addition, as of mid-2013, margins for diesel produced on the U.S. Gulf Coast were running just above $16 per barrel, while the margins on finished gasoline were much lower at just under $8 barrel (According to CNBC).
With increased demand and better margins, refineries must maximise diesel production to increase their overall profitability. One way refiners can maximise production is by utilising the PAC MicroDist, an online distillation analyser providing boiling range characteristics of various petroleum products and Cetane Index calculations in accordance with ASTM D4737 and D976. Online microdistillation data enables refineries to move the temperature of the cutpoints closer to the target without waiting for laboratory measurements. This helps refiners produce more of the expensive product and less of the cheaper product. Increasing T90% by 1°C may result in 0.5 to 1% additional Diesel production; depending on production capacity, this can impact up to $1 Million USD of incremental profits.

In addition, you can read the case study about a large refinery that produces over 350,000 bpd which reported their results when utilising the PAC MicroDist. Overall, the refinery reported the following results after the 720-hour MicroDist evaluation:
With the fast analysis time, the refinery could calculate cut points as fast as the variables were changing. This allowed them to minimise product giveaway and maximise their profitability.
