Dec 13, 2010 · SOR & EOR are two different sets of operating conditions. SOR or BOR = Start/Begning of Run ie when the catalyst or equipment is fresh EOR = End of Run ie when the catalyst is decayed or the equipment is fouled or has lost its efficiency.

The lowest temperature at which plant is commissioned to yield desired product quality for example sulfur of 0.5 ppm is called SOR. When the catalyst deactivation is reached to the extent that it has to be regenerated to get specified product quality we say that it has achieved EOR.

In estimating EOR, determination of end-of-run (EOR) is highly dependent on the process feedstock. For example, for naphtha hydrotreating, mercaptan recombination, catalyst poisoning (e.g., silicon [Si], arsenic [As], etc.) and pressure drop determine EOR.

What is the difference between these two working conditions? SOR (Early Running) EOR (at the end of Running) The end -stage hydrogen consumption, reduced catalyst activity, good initial catalyst activity, etc., search.

sor就是新催化剂运行初期，在初期催化剂活性比较高，反应比较剧烈，所以在初期一般要控制反应温度不能太高，防止发生飞温； eor表示旧催化剂运行末期，这时一般催化剂经过近一个周期的运行，反应活性有所降低，这是需要提高反应温度来保证生产所需要的活性，因此此时温度比较高，但是如果催化剂床层温度不均衡，存在径向温差的话，如果达到了反应器的最高操作温度，就要停工换剂或催化剂再生了。 加氢反应器 （如 乙烯 分离工艺的碳二加氢反应器）的EOR …

Dec 15, 2014 · The aim of this work is to apply a simple deactivation model that considers the three stages of deactivation, i.e. SOR, MOR, and EOR, to simulate the catalyst decay occurring during the main hydrotreating reactions of heavy oil in an isothermal bench–scale plant.

Nov 14, 2016 · SOR means start of run. EOR means end of run. A run is the period (6 mo.,12 mo., 24 mo., etc) during which feed is introduced before shutdown for catalyst regeneration or replacement.

... temperature profiles at the start of the run (SOR) and the end of the run (EOR) are represented in these figures. Figure 9 compares the temperature profiles observed in the industrial reactor...

Nov 26, 2009 · SOR ( Start of Run ) and EOR ( End of Run ) are usual representation of process conditions for fixed bed catalytic processes in Basic Design. In basic design you receive SOR Process Flow diagram together with complete heat & mas balance which shows you the start-up process conditions.

Nov 21, 2024 · Some of the residual oil after primary and secondary production can be extracted by enhanced oil recovery (EOR) methods. It is important to first perform an EOR pilot to estimate how much oil remains in the field, how much can be produced and at what cost.
