Multistage centrifugal boosted with piston pump
Thanks, I have attached the scheme. Basically would mean replacing P-Q201 (a centrifugal) with a piston pump. I understand the inconsistency of the flow from a piston pump and that the multistage would be jumping all over the curves in a very narrow band. Pressure reliefs and other safeties...- Unotec

Multistage centrifugal boosted with piston pump
We have this discussion going around regarding the booster pump for a multistage centrifugal. We need to boost into the multistage due to filters between the pumps. Typically, I use a centrifugal pump as a booster. Some people here are proposing using a piston pump for boosting. This doesn't...- Unotec

6 Top Challenges for Engineering in the 1st Quarter of the 21st Century?
miningman, the fact that you use the word immigrant is not racism at all. The comment about "leaving his attitude behind" referring to cultural/work backgrounds is what struck me as such. When you mention "I do have a problem with ANY individual who expects the accepted local standards to be...- Unotec

6 Top Challenges for Engineering in the 1st Quarter of the 21st Century?
miningman Well, gotta tell you that reads a little racist. If I have found one big challenge is the poor engineering quality of Canadian engineers in the West (O&G). Needless to say that, for the most part, university curriculum tend to be far broader and more disciplined outside Canada or the...- Unotec

Plate & Frame Hex hot vs cold sides differential pressure
Just got back from site. I verified and the mfgr specs are 6kPa differential on the sides. Looking at the damage, yes it was caused by the bending of the plates due to the differential in pressures. Apparently one exchanger was damaged when the oil got thick enough that the pressure drop was...- Unotec

Plate & Frame Hex hot vs cold sides differential pressure
Good day, We have a problem with a crude oil cooler. The oil comes from a high (80ºC) process at a relatively low viscosity (1.38cP). It is cooled down by water to about 40ºC, where the viscosity increases to about 7.33cP. The problem is that, as the viscosity increases the differential...- Unotec

What is fire?
rb1957, I agree that fire is the RESULT of a chemical reaction, but not always fuel and O2, is it? And if fire is heated gas and I heat gas (not necessarily through combustion) why would it not glow if fire is nothing but heated gas? As someone in the chemical business might appreciate, there...- Unotec

What is fire?
ok, so if fire is gas, then if I add enough heat to it, it would glow, correct? <<A good friend will bail you out of jail, but a true friend will be sitting beside you saying ” Damn that was fun!” - Unknown>>- Unotec

What is fire?
Well, did try to explain the intensely heated gas, but she's my daughter.... and her reply went along the lines of I don't believe you and bodily warm gases being expelled and don't make light. So what I tried to do was get iron hot enough to show her the glow. Damn pine wood, did not get hot...- Unotec

Emergency Purchases
ajack, you'd be surprised when a process emergency purchase has to go through the hands of accountants and such folk.

Recent Volcano Greenhouse Gases
I've heard the volcano eruption will block sunlight and cool the world. So if this is true, and the CO2 somehow, by miracle, is not generated in a volcanic eruption then why worry. Now that the US coast guard is going to set the Gulf of Mexico on fire (or so I've heard), there should be enough...- Unotec
