Alkylation process selection (sulfuric acid method): DuPont or Ruums? Or something else? An experienced senior, please share the actual production situation
Thread Content
Dear experts, the company is eager to install a new alkylation unit. Although the sulfuric acid method is proven to be effective, there are still concerns regarding the stability of operation over cycles of at least three years. Excuse me, everyone? Sulfuric acid process: DuPont or Ruems? ? Are there any recommendations from those with practical experience? Or ionic liquid method/solid acid.
Currently, there is strong competition in the alkylation unit sector due to adverse market conditions; many of these units are operating at suboptimal capacity or have been shut down. It is recommended to consider this decision carefully. As for the choice of process type, since sulfuric acid-based DuPont alkylation has been used traditionally, it is recommended at a broader level to choose between sulfuric acid-based alkylation and Rumus alkylation, as both are well-established processes.
Companies everywhere are still planning alkylation; they’re all competing for raw materials
If you invest now, you’re bound to end up in trouble~~~ Invest in those with lower costs; that way, you’ll suffer less losses:L
Last year, our unit conducted a survey and gave up on it.
The Rums process is still simpler, requires less investment, and is safe and reliable. If domestic digestion technology is to be used, turn to Luoyang.
There’s no problem with liquefied gas; the company has expanded its use of aviation fuel while reducing diesel use, which has led to an increase in liquefied gas production.
As long as the raw materials are available, using an alkylation unit is a good option. The current low operation rates and limited processing volumes in the alkylation industry are mainly due to a shortage of raw materials; nevertheless, the overall efficiency of such units remains quite high.
