Unit pressurization time

Unit pressurization time

Unit pressurization time

Dear All,

we do have the particular compressor system, connected to the gas/oil separator throgh the pipework. Before starting up the compressor unit (which consists of the three scrubbers, two coolers and two compressor' casings) should be pressurized by opening small 2" by-pass gas line from separator (the gas is flowing through 2" globe Fisher valve). The initial pressures in separator and in compresor unit (basically atmosphere) are known. How can we calculate the time, essential to presurize the comprssor unit till separator pressure. The volume of the unit is known as well. I'd assume some integration method must be used?!


RE: Unit pressurization time

It's essentially the reverse operation of blowdown or depressuring.  If you do a keyword search on the site, there was quite an extensive discussion on it not that long ago.

RE: Unit pressurization time

Sorry, respected TD2K can you please recall where it was as there is an extensive amount of threads (or even nothing) I found by keyword search.

RE: Unit pressurization time

Take a look at Thread124-17301 and Thread378-49081.  The process in your case is reversed but the procedure would be the same.  I'd simply set up a spreadsheet and work it out.
