Now, more than ever, while we practice social distancing and isolation to protect ourselves and others, we need our community to support each other. In this spirit, Refining Community hosts eREFCOMM a virtual event for technical sharing and remote networking. The concept will be in the spirit of our favorite live conference activity, the break out session. Every other week, we will have a new short topic and lively discussion around that topic.
- Interactive Webinars
- When: Second and Fourth Thursday of each month
- Time: 8PT, 9MT, 10CT, 11ET (1500 GMT)
- Duration: 60 minutes

Many refiners are struggling to meet new product specifications and improve refinery margins simultaneously while dealing with large resid pool. The choice for resid upgrading technology and flow scheme is of paramount importance especially in the face of the IMO 2020 regulations.
In our first Breakout webinar, participants will discuss the effectiveness of their site’s feedback loop, share successes and pitfalls, and learn from the experiences of their international operations colleagues.
The production of foam above the level of the coke bed during and after coke drum filling is just part of the process and is inevitable (generally). There are various scenarios where more or less foam can be expected. As part of this webinar, we will explore how foam can be reduced or managed with antifoam chemicals and through process awareness.
Operator Training Simulators (OTS) have long been utilized to improve the skills of an operational workforce, thereby increasing plant performance…

Corrosion under insulation (CUI) is one of the best known and researched corrosion mechanisms in process industries. CUI is not often discussed in the context of the delayed coker specifically or especially around the drum structure equipment itself.
In the beginning, the preferred valve of choice for delayed cokers was the lift plug valve. For many of you who still work on older units, you know this because all your valves are still this type.
The heater charge pump is arguably the most critical pump in the entire delayed coker. It can also be the most challenging to keep properly ready in standby mode so it is hot and ready when called into action and QUICKLY.
For many years, the only indication for the coke drum level was the Neutron-Backscatter (NBS) type. Then in the 90’s, continuous level gamma source instruments were developed. Their rollout has been gradual for the existing installed capacity and they are the standard on new grassroots units.
Our goal is to keep the coke in the coke drum, right? We are not always completely successful in this mission but one way to keep the drum vapor line clean is to minimize carryover from the drum and quench the vapors “enough” to prevent coke deposition on the ID of the pipe.
Traveling the coking world, we have literally talked to 1000s of operators and opinions vary about the ‘best’ way to switch the drum and steam strip. In this installment of eREFCOMM, we are going to investigate the variety of techniques in place and discuss the pros and cons of various methods.
