I’m curious what solutions you guys who are chilling your hydrocarbons in a seperate jacketed column pre-injection with CO2 or other methods are using to measure the temperature of the liquid solvent inside the columns? I have 3/4" triclamp connections on my top column lids so I need something that can enter the column through one of those, but I’m daunted by the seemingly endless types of thermoprobes. I just need something that can measure from 0C to -80C and can be snaked in 5-10 inches into my column with a 3/4" triclamp connection.
So I think I might have figured out part of it. It seems like there aren’t any 3/4" triclamp thermowells in the market, but I’m thinking if I get a 1" or 1.5" triclamp thermowell then slide a 1.5" to 3/4" cone reducer over the well, I could then clamp that to the 3/4" triclamp fitting on my column lid. Now i just need to figure out what probe to get to slide into the well as well as what reader i should pair it with. Also should have mentioned i have 4 columns I’d really like to read using one reader with 4 inputs. Any ideas guys?
Funny story while we’re at it: we were looking for a combo high pressure transducer RTD unit that would read accurate vessel temperature. We found two options, one was awesome but a bit pricy (about $800/unit). The other one was like $200 but they ended up coming in months late from the UK and had hella temp latency. While we were waiting, I reached out to TESCOM because they had an option that is basically this exact omega sensor with a 20ksi pressure rating; I figured in the interest of time we’d just throw two units in to get through prototyping. I was pretty blown away by the $16000 quote we got back. And lead time was, I shit you not, “whenever they need more for the F16s”.
Pretty quickly realized I was in the wrong room lol. I guess that’s probably a new level of “this sensor REALLY can’t fail or its a problem”.
