    CO2 capture system for engine exhaust - field movable

    Capture, store in barrels (liquid?) and dispose, probably at a CCS facility. Came across this recently and got me thinking of options, especially if miniaturization is not a requirement - https://www.sciencedaily.com/releases/2019/12/191223122804.htm Seeing as you are a petroleum engineer, I'm...

    CO2 capture system for engine exhaust - field movable

    Is there a viable, field movable CO2 capture solution that exists in the market for engine exhaust? Field movable = something transported on the back of a flat bed truck and not requiring permanent installation on the ground Capacity = ability to capture atleast a proportion of ~700tons of...

    How to do a pulsation study for recip

    How do I learn how to do this? What are the tools, skills sets and knowledge required to be able to do one for reciprocating compressor packages? Thanks,

    Torque friction coefficient - SAE grade 40 oil

    All - Thank you for the answers. I think the consensus for the "fudge factor" being 0.1-0.2 is reasonable backed by the MIL spec. I will take up Tmoose and dvd's recommendation and replicate this exercise to determine the target torques. I can actually do this on the flanges themselves as we...

    Torque friction coefficient - SAE grade 40 oil

    I am trying to determine the friction coefficient to use for fastener torque calculations for grade 40 oil as lubricant. Google searches are not giving me any reliable information, some papers use values from 0.1 to 0.2. From where can I get this value or is there a standard way to calculate it...

    Flange alignment per PCC and B31.3

    What is the reciprocating compression acceptable standard for flange alignment? Is it ASME PCC-1's 1/16 (offset) and 1/32 (parallelism), or ASME B31.3's 1/16 in/ft. (<1mm for 1.5 NPS 1500#, 1.4mm for 4 NPS 300#)? Are these actually achievable in field conditions? Somehow I feel once we factor in...
