The refinery has what is probably the only Houdry catalytic cracking unit still in operation in the world [1]. It has been in operation for 70 years.

Thank you Jacob.

Wonderful to see updates like this.

I noticed you also created the Visualization Chart. That is really helpful. You can further enhance the chart, by separating the connector-lines (arrows) also avoiding label overlaps. I moved the lines a bit, please see the effect below. I have not saved it. Leave it to you for optimization.

I will shortly also make sure, the Author of the Visualization Chart is visible in the Site-Page.

Hi Uwe,

Always a pleasure to contribute to the website. The experience of creating a mass balance model feels better with practice, it is now less tidious than it used to be.

I will start doing them on a tons/day basis, I feel like the conversion from barrels to tons creates some disruptions in the overall balance. 

Edit : Final result
