Hello folks, Probably an easy question for you but I don't have a clue. The compressors driven by GE turbines can initiate a shutdown or a shutdown with 'no motoring'. What do they mean with 'no motoring'? When is this required? Regards Frank

For a lube oil pump (gear type) of a compressor only an internal pressure relief valve is in place. I am sure that there should also be an external relief valve as there are some valves in pump discharge. Can somebody tell me where I can find this requirement. The pump will serve on a plant...

Hi gents, For a firewater main in current project the selected material is GRE. Due to the start of firewater pumps high surge pressures are developed. In the interpretations section of ASME B31.3 it is stated that ASME B31.3 doesn't provide an allowance for surge pressure above the hydrostatic...

Thanks Steve

Steve, do you have a reference to a paper wherein the ECE 4 model is described?

Thanks steve. Do you know if the BP Cassandra model is also included in ECE4?

Does somebody knwo how the TOL corrosion can be calculated in pipelines or does somebody have references to acticles on the web. I found 1 article from the NACE titled: "Top of Line corrosion and water condensation rates in wet gas pipelines" In this article it is explained how to calculate the...

Does somebody have any good information about the eventscheduler of hysys. I don't know what to fill in in the expression field for the if to evaluate true condition. every help/examples are welcome..

Moretena, can you explain why i have to size for unwetted fire case? Thanks anyway for your help.

Hi folks, does somebody know if hysys 2006 (depressuring utility) is capable to estimate the size of a relief valve for a fire case (api 521) when the fluid in the vessel is above it's critical pressure. There is no heat of vaporization sow i'm wondering if this is possible? We have hysys at...

hello all, i want to size a relief valve for a fire case. this valve shall be installed on a vessel which contains a mixture of water and light hydrocarbons. The pressure in the vessel is above it's critical pressure sow there is no heat of vaporization. How can calculate the max relief rate...
