Demand for our diesel has dipped. What process steps do you recommend for increasing gasoline make?

With the fall of pump prices, US consumers have responded relatively quickly by increasing gasoline demand, which has led to increased gasoline crack spreads and incentives for refiners to switch from middle distillates to gasoline in the short term. This phenomenon has been especially true in markets affected by unexpected outages.

We are getting organochlorides in some product streams and have traced this back to the catalytic reformer. Causes and prevention measures please.

Organochlorides are typically formed in the catalytic reformer when hydrogen chloride (HCl) reacts with olefins downstream of the reaction system.

Can you recommend a process route for residual fuel oil feed to help comply with the IMO’s revised targets for bunker fuels?

Refiners will address the upcoming January 2020 regulatory shift to lower sulphur marine fuels primarily utilising one of four strategies: (1) crude acquisition, (2) technology investment to produce compliant, low sulphur fuel oil (LSFO), (3) reliance on the persistence of an attractive market for high sulphur fuel oil (HSFO), or (4) conversion of HSFO to lighter products with the goal of either reducing their fuel oil production or exiting the market altogether.

Our tail gas unit is performing below spec. We are experiencing high levels of heat stable salts in the solvent. How do we deal with this?

The presence of heat stable salts does affect the performance of the amine solvent,1 consequently H2 S slip from the absorber may increase dramatically. To bring the H2 S slip back to acceptable levels, the amine solvent needs to be restored back to pristine conditions, either by a reclaiming process or by partial or full replacement.

What type of catalyst would you recommend for processing deasphalted oil in our hydrocracker?

The quality of DAO is primarily a function of the vacuum residue properties, SDA solvent, and SDA operation.
