I have a reciprocating compressor (2-stage vertical, double acting) for nitrogen services that is used to boost up the nitrogen pressure from about 5 barg to 35 barg, with a flow of 1000Nm3/hr. I’m trying to understand the basis of pulsation control that should be used for this reciprocating...
I'm trying to gain some insight if there are any common practices for vibration acceptance criteria when an equipment is not tested up to it's rated load.
For context: we have a generator which is connected to a turbo expander; the power generated would be a function of the process conditions...
I'm trying to get gain some clarity regarding to the requirements for design analysis for pulsation and vibration mentioned in API 674; it mentions that the purchaser should specify the requirement for this analysis if required. Annex C of API 674 goes on to describe the different approaches for...
For context:
I'm currently upgrading a pump for Low Sulphur Waxy Residue- the existing pump is a centrifugal pump with the following parameters (rated):
Q = 70 m3/hr
h= 160m
viscosity at pumping temp (83 degC)= 10.2 cP
density of fluid at pumping temp: 875 kg/m3
The upgrade consists of...
