Alkylation unit losses
Thread Content
Two months into operation, the alkylation unit is experiencing high levels of wear and tear. Let’s take a look at how much wear there is in each unit’s alkylation system, as well as what the yield rates are Currently, our loss rate is 4.5%; no emissions occur from the flare, and the raw material contains 2% methanol, which is removed after washing. What other factors affect the yield of alkylation?
As far as I know, the acid consumption is around 1%. I’m not yet aware of the material loss. Your facility has already started operating; I hope you can add 441222352 so we can communicate further
That means 45 tons of loss for every 1,000 tons – that’s not normal. Our daily processing capacity reaches up to 1,300 tons; at this rate, we’ll suffer huge losses!
Mainly, from which aspects is loss controlled?
We use the sulfuric acid method more often; the acid consumption is over one-tenth, around 13 percent. The loss is around three percent. The yield is around 80. If you have any good methods, please share them.
The information is quite comprehensive; the acid consumption in our device is around 12%, which is mainly determined by the characteristics of the raw materials
The alkylation process technology mainly focuses on adjusting the processing scheme, as well as the liquefied gas and oils entrained in the waste acid. Improving these three aspects will lead to significant gains; in addition, there are further technologies such as the use of additional small devices to reduce the amount of alkali used in the alkaline washing process, thereby cutting processing costs. QQ1472359555, let’s communicate more when we have time.
Was the liquefied gas and oil in the waste acid recovered?
Was liquefied gas and oil recovered from the waste acid?
Liquefied gas and oils entrained in waste acid.
The experience loss is 1.3%; our plant’s average annual loss is around 0.7%. The key factors in controlling losses include raw material quality, recovery of non-condensable gases, recovery of hydrocarbons from waste acid, and control of losses during loading and unloading
