Hi,
I have a question when specifying pressure drop across a control. If the upstream pressure is 300psig, and the fluid will flow to a downstream vessel operating at 30psig, would the delta P specified be 270psig? The fluid also has to travel about 200ft before reaching the downstream vessel...
Hi all,
We have an atmospheric storage tank containing chemical. I believe it is an API 620 storage tank, as the MAWP is 14.5 psig.
We need to install a PVRV (breather) on this tank. I am confused as to what the set pressure should be. I know an API 650 tank is not allowed any accumulation, I...
Hi,
I am looking for a manufacturer of an application/system that can provide continuous UV detection to identify if our pellets are off-spec or there is a more serious problem in our process.
We would like to do this before visible colour change occurs. Right now we can do this in a batch...
Hi,
I am looking to recover condensate from a heat exchanger back to the boiler. Condensate will gravity drain from the exchanger to a condensate tank and then it will be pumped back to the boiler.
I am confused as to whether or not I need a steam trap on the condensate line from the HX to...
I want to inquire about employment and career opportunities at a company. I have the name, number and e-mail of the recruitment manager but also of the engineering manager.
The question now is, do i bypass the recruitment manager and call the engineering manager directly? Would this look bad or...
Hi,
I have a vessel which is half-filled with water. They want to use steam to heat it up at a rate of 20 deg C per hour. How do I calculate the the steam flow in kg/hr for the required heat increase?
I have an offer from a major EPCM company. I am concerned about the falling oil prices, and how this will effect their work. They have a lot of employees, mostly working on oil sands projects, refineries, etc.
With oil at around $70/bbl right now, with signs of declining further, it is the...
Hi guys,
I currently have a bachelors degree in chemical engineering. Where I'm working, I notice that a lot of people have masters degrees and some even Phd's. These are the ones that seem to be in the top positions of the company, like director or managers. Granted, there are some with...
Hi guys,
For the past 2.5 years I have been working as a process engineer (chemical engineering degree) mainly in the oil ang gas as well as petrochemical industry. Recently I moved into a role in minerals processing (base metals extraction, refining, etc).
I'm worried if this is the right...
A quick question regarding methanol and vapor pressure. I am a little confused regarding the relationship between nitrogen padding and vapor pressure. We are designing a storage tank for methanol with a pad/de-pad system. I understand we need to keep a blanket to prevent o2 and air from entering...
Hey guys first time posting,
Here is the scenario:
A truck is filled with liq solution, they will use air at 25 psig to push the liq out into a pipe and to a tank.
I need to calculate a liq flow rate out of the truck to the tank. I have calculated the max flow thru the pipe from the truck to...
