What is a good flow measurement technology being used successfully in different refineries. The application is hot oil (400 C), 0.83 sp. gravity, 1.2 cp viscosity at 500 psig in 6" line at heater inlet. Normal flowrate is 10KBPD, max. is 20 KBPD. There is 1-2% solids in the stream. No purge oil...
Hello Valve experts!
We have a water booster pump circuit which has suction, discharge and bypass valves (all 24"). The water is mixed upstream of this pump with caustic due to process requirement (pH = 8-8.5, Sp. Gravity = 0.97, Pressure at suction is 60 psi and discharge is 100 psi, Temp. is...
I am looking for forms for the acceptance of electrical & instrument project work. If anyone knows any resource site please let me know. I will appreciate your help immensely.
Thanks.
Here are two good articles about control valve sizing and application. If you deal with control valve selection and sizing then you will find them very informative.

Gentlemen,
We are experiencing more than normal failures of these positioners. Usual symptoms are that positioner shuts down when the signal goes below 4 mA and loses configuration. Technician usually recycles power and reconfigures the parameters to make it work again. Last year we sent 2...
Hello Forum,
We have a large number of disk stack centrifuges (Alfa Laval).
The feed containing the liquid and the solids is introduced to the rotating centrifuge bowl from the top via a stationary inlet pipe, and is accelerated in a distributor before entering the disc stack. The separation...

Hello Folks,
We are planning to buy and install a "Total Chloride Analyzer" which uses Sensi-Tape technology (CI Analytics). I want some feedback about it's reputation in refining industry. The vendor claims it's been around for 30 years but I personally haven't seen one in action. So if anyone...
Hi Forum,
I have a scenario. I have an equipment which can use dry feed and wet feed or both. When we use dry feed we use lots of water (400 l/s), when we use mixed feed or wet feed we use very less water (75 to 100 l/s). The flow is measured by an orifice plate (16" line size) and transmitter...
Hello
I have to do 100 data sheets with same data (different tag numbers). Is there a way that I do one data sheet then copy it to other 99? Any help will be appreciated.
Is it worth going for PMI or PMP certification for an instrument professional. I am mostly involved with design and QA of instrumentation & Controls of small to mid level projects.
What are the requirements to install a fire safe valve on Hydrocarbon service. We have two vassels which contain bitumen+naphtha and have fire safe valves installed at the discharge but we also have a Naphtha tank without a fire safe valve. Naphtha tank is a lot smaller though. Does it still...
Hello,
I am looking for a pH meter for oily water service. This stream has 1-4% bitumen and has 10-15% sand. The line size is 16 inch and line pressure is 70 psig. Temperature is around 60C. I was thinking about installing the probe into a slip stream with an isolatable system. Any suggestion?
