To what extent is pretreatment needed to protect hydrotreaters/hydrocrackers from impurities when upgrading WPO to petrochemical feedstocks?

What new FCC stripper technologies are available that can deliver higher efficiency and optimised heat and pressure balance?

What optimal mass transfer/product separation configurations benefit the integration of catalytic reforming and aromatics complexes?

What incentives and technology are needed to make refinery-based cogeneration of electricity and steam profitable?

How can smaller refineries compete in an industry dominated by mega-refinery/petrochemical facilities?

What strategies can be considered to meet the expanding paraxylene market?

I wanted to know the possible problems and consequences of processing high acidity crude oil (HIGH TAN) and what is the solution? Isn't it better to process these types of crude oil in Delayed Coker or Visbreaker units?

Fluid Catalytic Cracking (FCC), Flue Gas Scrubber SO3 break through. We are facing with Wet Gas Scrubber (FGSU) outlet stack dense plume issue. It is taking longer to disperse and getting landed in nearby area causing eye irritations. As per licensor, this dense plume is due to SO3 breakthrough. Stack outlet analyzer only measures SO2 and and values are within limit. These phenomena happening during Heavy Sulphur feed processing and issue gets aggravated during winter season. We tried to limit the excess Oxygen in flue gas. Also maximized the circulating water. But no noticeable changes occurred Is any refinery facing the same issue and what are the troubleshooting activities have been carried out to resolve this issue? Will SO2 breakthrough occurs first before SO3, which not happening in this case? Flue gas composition: SO2, SO3, CO2, O2, N2.

The chlorides level in amine cycle of our gas sweetening plant have reached up to 1800 mg/L, what can be the probable causes and their solutions, also suggest vendors for the suitable systems.

In what situations do advanced catalyst formulations and technical support affect/benefit downstream product investment, such as when separating olefins?

Can you discuss your experience with using CFD for hydroprocessing reactor troubleshooting?

What evolving methanol-to-olefins configurations are feasible for SAF production?

How much silicon is critical in SMR catalysts?

How to decide the turndown of plant during design phase?

What is a latest technology for C2+ RECOVERY & FRACTIONATION PLANT shall be designed to Produce C1, C2, C3, C4 AND C5+ as PRODUCTS ?

We have low PH (3 to 4) in the CDU overhead but in same time we have low chloride values ( 3 to 10 ) and already we injected high values of neutralizing amine and corrosion inhibiter. What is the reason that causes this drop in PH value?

What process and operational areas have refiners demonstrated a positive ROI in the application of artificial intelligence and machine learning strategies?

I would like to know which are de main strategies (related to WABT of the beds) for operating an hydrocracker unit in order to minimize the catalyst deactivation and extend as much as possible the catalyst life. The unit has three beds: the first one with pretreating catalysts, the second one half preatrating half hydrocracking catalysts and the last one with 2/3 of hydrocracking catalyst and the other 1/3 with isodewaxing catalyst. There are 2 quenches between bed 1 & 2 and bed 2 & 3.

How can I calculate the salt point in an atmospheric crude distillation tower to avoid the precipitation of salts, what literature recommends.

(Cómo puedo calcular el punto de sal en una torre de destilación atmosférica de crudo para evitar la precipitación de las sales, que literaturas recomiendan)

In our vacuum distillation unit, in HVGO section temperature difference between vapors entering into the bed from below and temperature in the bed has come down to less than 10 degc from almost 50 degc after unit emergency shutdown. This has lead to high temperature across bed 1-3. What could be possible reason for this and what are potential impact of this column yield pattern? And what are the remedial measures for controlling this without going for any shutdown?
