Perhaps this can be of some use: https://www.aluminaceramicball.com/size-selection-and-function-of-inert-ceramic-ball/
I'd also consult GPSA Databook and vendor recommendations.
Good luck

The only way to get the exact (or as close to exact as possible) values of alarm set points, is to perform quantitative risk assessment - by analyzing possible/potential scenarios. This means: location(s) of the release, pressure, hole size, ambient conditions, site geometry, etc. This will tell...
One of the best indicators out there is to compare average(d) annual cost of maintenance and capital cost of the equipment. It is frequently titled as RAV, or Replacement Asset Value, and it is expressed as a percentage.
The more data (years) you have, the better, because having just a year or...
Run a model of your system by using 100% tray efficiency and vary the number of trays until you get the same quality of top and bottom products, for actual reboiling and reflux ratio. Then divide the number of trays you get with actual number of trays in the column, and that is efficiency...
See if this helps.

As long as the Hydrocarbon gas stream is not limited to very low CO2 spec, you can virtually regenerate any amine at high(er) pressures. This will of course result in:
1) Higher lean amine loading
2) Higher material cost for the lean amine circuit
3) Potential corrosion issues (depending on acid...
If there is an emergency scenario involving PW line - and some of those scenarios are mentioned by George and myself in previous posts - the valve on the PW line is qualified for title ESDV.

SDV and ESDV valve look exactly the same - being in the same physical location of course. The only thing that differentiates them, is whether they are a part of emergency shutdown logic or not. If the subject valve is a part of any emergency scenario, then it will remain "ESDV". If it's not, you...
It's just terminology, meaning that the valve is supposed to close upon initiation of an EMERGENCY scenario on the produced water line. Carrying less hazardous fluid than hydrocarbons does not necessarily mean that emergency scenarios are not possible/credible. There might be something you have...
Sorry for late reply.
Obviously, with a 0.3m x 0.85m "hole" (0.255 m2 area), the blast resistant wall is not going to be blast resistant anymore. As a matter of fact, this opening will act as a funnel for destructive blast energy generated by an explosion.
Without knowing more details, it is...
Dynamic simulations are required to establish set point for a HIPPS - this is exactly due to a different nature of any system out there (different volumes, different flows, different phase fractions etc.). So, you don't want a bladder accumulator, you need a well designed HIPPS. Secondly, a...
STEL refers to average concentration of 5ppm over time period of 15 minutes, hence you should not have a single detector triggering deluge at any instantaneous value of EtO concentration. Why not use 5ppm over 1 minute period?
What is typically used is to employ signals from two or more...
OSHA recommends avoiding permanently-mounted internal combustion engines in areas where flammable vapors or gases could be present. However it does not prohibit their use, given that appropriate certification exists (ATEX, NEC).
There are some units used in the North Sea offshore.

Look at DCS trends and find pressure spikes/surges during startup/shutdown. If you don't find anything, keep looking for similar profiles during normal operation, particularly for feed changes, start of standby pumps, etc.

Morten has given you a good advice. Get in touch with Gexcon (I used to work in their UAE branch and I know this is one of their capabilities). For more info see:

It is definitely worth investigating if you can manipulate the feed and provide a condensate blend that will not have excessive amounts of any of the distillates - this would be the most effective way to combat against the problem as you will be tackling the cause instead of dealing with the...

Thanks, I tried that one. No answer on emails or telephone calls. There's plenty of dead websites (and companies) around.

The HEX was in water-water service (demineralized water vs cooling water). I doubt this was a corrosion issue.
