The Keys to Maximizing Diesel Production

Routes for diesel production – Over the period 2015–2040, the global demand for diesel is likely to grow at a compounded annual rate of 1.0 per cent. Therefore, maximization of diesel yield remains the major objective of petroleum refiners. Read on to find out the various routes through which diesel can be produced in a refinery...

How to Make the Optimal Use of Scheduled Plant Downtime

A regular large-scale inspection of a refinery took place at Mineraloelraffinerie Oberrhein (MiRO) in Karlsruhe, in the spring of 2015. All 41 process plants in No. 1 Works as well as three plants in No. 2 Works were at a standstill for four–six weeks. During this time much more took place than just the fulfillment of legal requirements: The plants were cleaned, repaired and underwent further technical optimization and testing to ensure that they would run reliably and efficiently in the years ahead.
