Hi everyone Pls. help me with the following problem. There is 10 feet long and 4" in diameter blow down line coming out of LPG heat exchanger and I need to figure out the line temperature change along the line as result of opening block valve from this pressurized LPG heat exchanger to blow...

please help with the following There is a fractionation column which has multiple safety relief valves installation on top. Also, the column is equipped with depressurization pressure control valve. My questions are the following: 1-What is the function of the depressurization pressure...

We have new centrifugal pump and compressor, which are mechanically ready for placing in light hydrocarbon service. In short, the compressor will compress the propane gas and condense it through fin-fan cooler where the pump pumps the liquefied propane for further treatment. My question is...

There are 3 boiler feed water (BFW) pumps feeding 2 water-tube boilers. The BFW pumps supply the boilers with boiler feed water at discharge pressure of 900 psig and with pumping capacity that is good enough to feed the 2 boilers. The 2 boilers provide heating steam for process heaters. My...

We have 4 running centrifugal pumps. Each pump is equipped with 8” minimum flow recycle line. Each recycle line has flow control valve and check valve (downstream of the control valve. All 4 pumps discharge into one common header, 24”. There will be additional 5th pump identical to the...

Pls. help with solutions or ideas to recover buckled areas on a tank. We have atmospheric storage tank, 46 feet Diameter X 48 feet high. The tank consisted of 6 courses. The tank 24” inlet, located on course No. 3, was subjected to external force which resulted in buckled areas around the...

We have a heat exchanger, typ AES, that is designed to cool about 1000,000 lb/hr of light hydrocarbon liquid in the shell side with pressure drop of 3 psi. The cooling media is sea water, which is placed in the tube side. My question: How can I estimate the maximum hydrocarbon flow rate that I...

Can a control valve produce high noise (more than 85 db) under low pressure drop, say 20 psi or 30 psi? Thank you for your help

How can I compare world natural gas reserve vs. world oil reserves? Where can I find this information? I am writing a presentation and I want to tell my audience that gas reserve will last longer than oil would. Please help

Please help to list any processes on natural gas conversion i.e. GTL. I am preparing a presentation on future of natural gas say in the 20-25 years. My massage through the presentation is to tell audience that the future is “Gas Economy” by conversion of natural gas to finished...

During detailed design, how can I assure adequate area of an economizer for high pressure water-tube boiler? The boiler will produce 625 psig super-heated steams. Many thanks

How can I convert actual field flow transmitter signal read-outs (4-20Am) to volumetric readings, say GPM, without looking up the readings on the DCS display? (flow loop uses orifice plate for delta P) I am conducting a test and trying to directly use flow transmitter signal read-outs in order...

What are the proper producers to check the actual (field) operating conditions of a centrifugal pump, which is pumping hydrocarbon of 0.5 SG, vs manufacturer’s pump performance curve (medium test is water)? What are the tolerances criteria between manufacturer’s curve data and my field...

Cameron hydraulic data book has tabulated friction head losses for water in different pipes sizes at varying flow rates. At specific flow rate (GPM) and pipe size & schedule the tabulated data shows velocity (ft/sec), velocity head (ft) and head loss (ft) per 100 feet. My question is: Can...

We have a shell & tube heat exchanger which uses sea water for cooling the hot process stream. we need to install a PSV (pressure relieve valve)on sea water cooling stream based on tube faluir case. The question is that where should we install the PSV (on inlet side or outlet side) of the sea...

How can I start preparing for conducting process equipment performance tests like pump performane tests? Do you recommend any resources i.e. books, or specific industrial code requirements? Thanks

We have 5 high pressure (HP) boilers producing steam at 625 psig and 720F. Recently, we commissioned 2 Heat Recovery Steam Generators (HRSG), which produce steam at 625psig and 720F. These HP boilers and the HRSG units are inter-connected on the supply side to the steam headers going to the...

We are evaluating the use of "un-restrained coupling" joint in under ground oily waste water piping. This coupling joint is equipped with internal rubber gasket, which should seal the external of piping end. My Questions are: 1) Is this type of joint reliable in under ground oily waste...

We have total of two (2) pumps that are connected in parallel. The discharge outlets of these pumps are connected in 14” common discharge header. One pump is in operations while the second pump is on stand by. These pumps share one common minimum flow protection flow control valve (FCV)...

Hello Please helpe to find out the right equation to solve the following problem: There is a 16 in. line with 60 psig and 75 F gas (mathane) flowing in the line. If I want to make a 3 in. branch from this 16 in. line, which disharges to the atmosphere how can I calculate the gas velocity in...
