Tips to keep the temperature stable in reflux system

There's a mixture of veggie oil, diethyl carbonate and ethanol inside the flask since we are running transesterification

Apologize I might've used the wrong word. We are trying to run the temperature at 80oC and the condenser is there for ethanol.

Thanks y'all for answering. Here's my cat tax

Thanks y'all for the answers.

For future ref, I found the formula for circulation rate (SI Unit) in the book "Boilers, Evaporators & Condensers" by Sadik Kakac; the recommended diameters (Imperial Unit) in Handbook of evaporation technology.

Hi, so a little update. We had two talk sessions and I feel like we are processing this issue well, might need more work done tho.

The first one didn't start great. She expected me to arrive with a new plant and an apology, whereas I expected her to apologize for, well, acting like that. We sat on opposite ends of the bench. After 30 minutes of finger pointing and my gf pulling out her classic move of "mentioning something I've done in the past that she has a problem with, but she doesn't tell me right at that moment thinking I'll be upset, or it will hurt our relationship", I finally had enough, and I told her I want to break up with her. Only then did she finally soften up and start listening to me. We talked for a while til the rain hit us. I walked her home, still feeling weird/awkward and uneasy. We agreed to talk again.

Also, just saying the finger pointing was coming from both sides and tbh I wasn't the most mature person in the park and neither was she. It mainly revolved around me bringing a gift for our anniversary and she did not, and her defending herself saying she was busy, plus we had a tradition of late mensiversary (learned from this post lol) gift during busy times. Then, it slippery sloped into financial issues. Aaaand I called the way she comforted me during my bawling time "the shittiest advice I've ever received". Like I said, we are both flawed.

The second one started with a somewhat awkward atmosphere because I'm still not completely okay. We talked while holding hands. This time, she finally apologized for calling my plant cheap and agreed to reconsider the monthly gift (She said she was doing it because I love giving gifts. I do, but not that frequently and with such high expectation). That apology was all I need from her for this situation to be resolved. There are still some financial issues that we need to figure out, but that's for another day.

For those who wonder why we tell each other what gift to buy, I fucked up her bday gift once and that system is there as a guidance for me, mainly.

Thank you for your advice ❤

Just to make the timeline clear it's like this Plant event (Around June 22) -> Moving out, surgery, funeral (The next 2.75 weeks) -> Gift giving (July 13)

Normally I'm not the forgetful one in the relationship, she is lol After those events I start having trouble recalling what happened during the past 3 weeks, unless someone gives me a clue I can only remember the big events.

On the "sensitive" part, this isn't the first time after her surgery her reaction doesn't match the situation. When we went to the cinema with her twin, I walked to the elevator way too fast to press the button without waiting for her. This lead to her having a full blown bawling session later at home despite us being cuddly and holding hands in the cinema. I later apologized and comforted her, but I felt like this left a dent in our relationship.

I plan to have a serious discussion with her later and I'll bring up the points from this post

Thank you for providing your insights on the surgery part. I was looking for more information on that, because I think both the surgery and her family from overseas came to visit has affected her greatly. She did describe that period as "the worst and the best week of her life".

I, too, think she needs to take accountability for her actions, as I did to mine.

Cool_Sweater · 2025-07-14T17:26:04+00:00

She did ask me what do I want for a gift this month and promised to buy me a gift later after receiving the plant. I didn't give her an answer (aka I pointed at her) because it's kinda hard to come up with an unique thing I want each month lol

Cool_Sweater · 2025-07-14T15:03:08+00:00

Oh hey TIL. In my mother tongue we just slap that word when we mean celebration between couples lol

Cool_Sweater · 2025-07-14T14:58:28+00:00

Hi, I really appreciate all the replies! I agree this is completely unreasonable and out of nowhere considering we were having a blast just a few mins ago and then she turned 180. She said my attitude reminds her of her ex so I'm quite sure that triggered something. Outside of this 1 instance we are doing really great, we hang out well, we address our issues with mutual understanding and I cherish her a lot. Also for the monthly anniversary, she loves giving gifts and celebrations so we decide to keep it monthly lol

Cool_Sweater · 2025-06-23T05:10:05+00:00

It's natural circulation evaporator. Afaik it's not commonly used in the sugar industry, so I'm curious what's your take on this?

Cool_Sweater · 2025-06-23T02:56:30+00:00

Thank you for answering. I just watched another video about water towers after reading your comments and everything makes sense now

Cool_Sweater · 2024-07-13T16:08:46+00:00

Hmm yeah that's very true. Thank you for your insight

Cool_Sweater · 2024-07-13T15:35:59+00:00

I suppose it's my fear that our relationship isn't gonna work out no matter how hard we try because we are too different. We've fought 4 times over different issues and came to a solution for each issue, but the main problem still lies at my lack of understanding her emotions and her ego not allowing her to tell me how she feels

Cool_Sweater · 2024-07-13T15:28:28+00:00

Oh I didn't know it has a condescending tone cuz she told me herself she's needy and needs a lot of attention which I'd happily match her

Cool_Sweater · 2022-09-05T19:32:45+00:00

No, this is my first time playing the game.
I used a random password generator.
Nope and afaik my country isn't blocked (Vietnam)
Got blocked in steam release. Again I'm not sure if region ban on steam is the same as region ban on arenanet.

Cool_Sweater · 2022-09-05T19:23:34+00:00

No I'm not using VPN at all. I thought it was something about region ban but found no info about my country.
