I found big discrepancies between our relief valve sizing and the vendor sizing for fire scenario in unwetted vessels when F' is less than 0.01. The discrepancies are based in the version of the API 521 used for the calculation. Our calculation were finalized last year and based in API Std 521...
I am working in feasibility study.
We want to change the service of two existing tanks in a storage terminal.
The new product to be handled in the existing tanks will be condensate (light naphta), with a maximum RVP of 15. The current tanks are floating roof.
For the new service these ones...
We have this problem.
We are designing a tank that will receive 2200 BPD of foamy oil at 80°C. The inlet nozzle will be located at the top of the tank. Inside of the tank the normal liquid level is 5 feet. This equipment is not insulated; only personal protection insulation is needed, because it...

We are designing a sample connection to be installed in a 2" produced water line. this lines operate in a intermitent service.
Is it possible to install this sample connection without a sample quill?. Pipig group has problems with the installation of quill in small diameter lines. The other...
Where could I find guidelines to design a relief valve (fire case) for a amine-lpg tower (liquid-liquid contactor tower).
I know that the relief valve will open in fire case when there will be vapor in the top. However the relief valve will handle liquid-vapor mix. How can i estimated the...
I am calculating the length of interphase batch in a pipeline which will operate with two differents crude oil in a batch mode. I am using the Austin-Palfrey formula.
Is there another formula to calculate interphase batch??.
I would like to know your comments.
Regard, Hianbo

We are designing a pipeline to send Extra heavy Oil diluted with a water composition of 0.135 % mol. We are making the hydraulics calculations in Pipephase. However we are getting from the program that the stream increases their temperature when the pressure drop. It is possible this effect on...
Some one could help me in known required minimum pressures for running smart pig.
We are designing a natural gas gathering network that will operate between 58 psig and 109 psig. However we would like to know if it is possible run smart pig with this application. I know that this is...
Will Someone have experience using mechanical interlocks for the valves associated with Pig Launchers and Receivers??.
In our company want to implement this kind of interlock in order to have safer operations, in all pipelines (gas, crude oil, etc).

In these moments we are designing a relief valve (for blocked outlet) of a natural gas gathering system from wells, considering the maximum flow of gas that hopes to be had in 25 years of production. However We would like to know that it will happen in those years that the gas gathering system...
Right now, We are designing a Natural Gas Gathering Pipelines from different oil produced clusters. In the actual design we are considering use pig traps in the main trunklines, but we are thinking to use pig valves for some branches (economical reasons). However we have not had experience with...

Hi:
Anyone knows of how to estimate instrument air consumption by pneumatic instrument?
Normaly, during engeneering phase instrument air requirements are estimate as 0.072 kmol/h for each consumer of instrument air, such as valve positioner on control valves loop or 0. 144 kmol/h for actuator...
We would like to know the experience in using disc pump technologies for multiphase application.
We want to use this kind of pumps in upstream application in our facilities, in order to send Oil, Gas and Water from the Wellheads to the production facilities. Several pumps will be connected to...
