We are excited to be Strategic Partner of the World Refining Association’s ERTC: Ask the Experts. This new event from the organisers of ERTC, the biggest and most important event for the European downstream industry, is the only event in Europe offering process and maintenance engineers a platform to ask their burning questions about the everyday challenges facing their plant and hear the practical solutions from industry experts.

This face to face interactive event, features experts from leading European refineries and technology providers; engineers will have the chance to hear unparalleled knowledge through interactive discussions such as fishbowl panels, Q&A Panels and Poster Sessions.

07/08/2018 Q: What are the safety precautions that must always be taken before entering the Confined Space Work in order to install the floating suction inside the tank? (1)
07/08/2018 Q: I would like to ask you about the problem that we are currently experiencing now is a sudden increase in differential pressure reading unusually for FILTER WATER Separate , And MICROFILTER . Which led to the change filter elements in each shipment quantity of up to 225000 litres only, although pursuing fuel shipments during the receipt, and the control checks of the fuel samples from the batch In terms of (water,sediments, appearance, electrical Conductivity and Density), All the results Within specification.
What are the expected reasons that may lead to this sudden rise and exit of the differential pressure reading for the allowable limit?

06/08/2018 Q: What can possibly cause an implosion inside FCC Reactor Riser. We presently have an implosion inside our Reactor Riser. The section /area assumed triangular in shape rather than the original circumferential shape. The incident has drastically reduced the I.D of the riser in that location, restricting normal flow through it.  
03/08/2018 Q: Anyone suggest me about increasing Propylene production in FCC without affecting stripper dp. In our refinery 2 Reactors or working in poly Propylene unit (PPU) for poly Propylene production and feed sent from FCC to PPU. Now 3 rd Reactor is commissioned in PPU but not any changes in FCC for increase Propylene production. So kindly suggest me which type of changes is required in FCC technology or process data's to increase Propylene production. (4)
02/08/2018 Q: What is the meaning "octane barrel"? (2)

01/08/2018 Q: We have a DIesel Hydrotreating Unit. In feed furnace we have Austinitic steel coils. During short shut down, UOP manual says to maintain the bridge wall temperature as 205 C, to prevent the polythionic acid corrosion.
Can anyone tell the basis of temps as 205 C?
