Hi, I am looking for design guidelines and/or a picture of a a subdewpoitn reactor (liquid is produced by the reaction and need to be drained). How much in percentage the catalyst bed represent in length of the equipment? Thanks for your time, JD

Thank you guys, I used the Thermon software (http://www.thermon.com/us/default.aspx)for the calcs.

Hi, I would greatly appreciate an advice on the installation of induced air coolers in a place with heavy winter (I'm worry of heavy snow falls). Any experience (reference)? Thanks for your time, JD

Hi, I would greatly appreciate if somebody can recommend a good reference (or steps) to estimate the heat tracing amount require for a specific project (not really rigorous calculation since we are in pre-FEED). Heat tracing will be done using triethylene glycol. Thanks for your time,

Thanks for your comments. We are probably going with two pumps.

Hi, I would greatly appreciate some advice in HOW and WHY it would be better to have TWO PUMPS or ONE PUMP (both with spares) that feed two columns (different process) and a filtration system. I am designing an application that has two main sections: H2S absorption (tray column) and SO2...

Thanks for your answers I ran a calculation for a horizontal vessel resulting in almost the same size as the vertical result. So, just choosing based on the space in the plot area I went with the vertical drum no demister.

Hi guys, The design case is based on a gas flowrate that is only 0.2% of the total flow. So, the calculated demister size using GPSA equations is super small (1"). The vessel is designed on the liquid flowrate and residence time (vessel ID 4'). How effective will be to have a mist eliminator...

Just an incinerator. We decided to included the demisters in the final design as an extra safeguard. Thanks for your responses. JD

I forgot to add that this vessel is downstream of a amine regeneration drum. Do you believe in the possibility of foam accumulation downstream? Do I need the demister as an extra safeguard? Thanks for your responses. Jenny

Hi, I would like to know: How critical is the need of a demister in a KO vessel upstream of incinerator? The liquid content is about 0.32% of the feed. Is it a good practice to have a demister or not? Thanks for your time. Jenny

Hi guys, I am designing a PSV to protect piping and a hairpin that heats gas from 41 deg. C (29 barg) to 288 deg.C. The PSV is going to be located in the cold inlet piping. The case that I'm analyzing reflects a block outlet that derivates in thermal expansion of the gas. I checked by...
