Cgcl capturing co2 from the air is music to my ears. I was wondering of it is feasible to extract co2 from air, as it's a lot of air to process, to get the co2 in the quantities necessary for a process plant.

Now I want to know how THEY do it... Do they do like the ammonia pants and chemically scrub it from air, or would they do like what I thinking about doing and chill it from the air....

I could ask but as of late I have come to the conclusion that some of these plants are populated with complete brain dead morons that have not one clue as to what is going on. The only way you sure to get accurate info is if you find an engineer and ask, even some of those got in by jumping over the back fence and wearing a nomex with company logo.

Classic example, if you none the wiser, people swear by the fact LNG is frozen for transport in marine vessels. This is to minimize the rocking movements from turbulence.

[sMASH]

Wtf!!,
Bro...

[sMASH]

It's INNN the name... Like boy scouts.
LIQUIFIED natural gas.



The ting about trini I can't stand is, they invent a reason to justify the bs.

*rocking of boats*.


Do they freeze the oils on tankers too....

Mc.

LNG is just the name of the place they said

i asked the same thing, if they freeze oil, fuel and methanol.

[sMASH]

Mc

From what I recall carbon is obtained from the syngas stream, plant can run without carbon from other sources but additional CO2 is welcome to increase yields. I really dont recall seeing a carbon dioxide plant on site.

Leme see what I dig up.

I also do recall seeing a tuner badge on someone ride there, if only the person will come forward.

[nervewrecker]

By product of other plants
Aum ammonia supplies downstream with ammonia and co2
Ax supplies mx I think

Q: they dont take co2 from the air by chance? or cant?

I don’t think a skid for that in the plant design

The 3 ammonia plants have co2 scrubbers
N2000 uses benfield solution and I can’t remember what cnc and aum uses

see what happens when you ask someone who knows jack chit and not take on pointless babbling from people.

[sMASH]

That's how the nh3 plants remove co2 from. Those systems.buthow does cgcl get additional co2?
From the atmosphere? Okay, but how, a chemical process or by chilling compressed air?

[nervewrecker]

aye, one thing at a time

[maj. tom]

Industrially CO2 is produced by combustion of methane, since distillation and liquefaction from air would be inefficient and low yield.



They probably also don't waste it when created as a byproduct of other reactions like here:

I trying to remember off the top of my head what was the first refrigerant carrier used in the printery, it sounded like dme

Traditionally, yes.
But given the new green revolution, not sure if newer places trying other methods.
I personally gonna try freezing it out of the air.

I think Amazon has a machine to create dry ice. Removes CO2 from the air.

Gonna build your own?

Was researching possible sources for my use.

Yes.

But I worked in an ammonia plsnt and became familiar with the chemical scrubbing of co2 from the process.


So, just wanted to know if the big billion dollar companies came up with other means of extracting co2 from air other thsn chemical scrubbing.



Not a lot of co2 In air, compared to just burning methane. But burning methane has a cost.

So would really like to confirm. How cgcl generates its co2.







Thwt is one item of interest.
The other is, how GTL back end generates its diesel: syngas to converter and out comes diesel, or syn gas to converter out comes some material which is then sent to some other step that creates the diesel.

[nervewrecker]

And what are your long term solutions for the captured carbon?

Create fuel and return it back into the cycle? Plants are a long term solution being carbon based or refrigerants since refrigeration is now a necessity with global temp rise. R290 aka propane is a direct drop in replacement for R22 and I had retrofitted a lot of systems with it as a long term solution. But there is still the debate as to if global warming is real and its not just fluctuations of the suns temp.

Hempcrete is another long term solution but we not ready for that here.

[nervewrecker]

Actually retrofitted a few 410a systems with R290 as well.

Light commercial systems use same line sizes in some units, so I doubled the metering device capacity to half the pressures and drop the compressor RLA.

410a is 400 to 500psi discharge and 110 to 150psi suction, R290 is 240 to 300 psi discharge and 67 to 70psi suction so the compressor is almost at half FLA. Good luck to the poor sap's that have to work on that yes.

[sMASH]

And what are your long term solutions for the captured carbon?

Create fuel and return it back into the cycle?

Yes.


But, my experience is, the engineers know HOW to calculate, but not WHAT to calculate.

They think inside the parameters they have encountered.



I need to do it myself and see what I can see.



Need to know how GTL back end works...

Come now, surely all engineers cant be painted with the same brush. There are engineers and then there is engineer, a gift to mankind from god, the best thing on the face of this earth, carved out of milky white pure marble to perfection and bought to life.

[sMASH]

Our engineers are glorified calculators.
Foreign engineers need to be able to innovate and ask questions and investigate.

Our get trained to fill in plant data for the end of month meeting.

[nervewrecker]

Not quite sure how to take that since me and the engineer does the same job just different departments and different places with two different titles.

I on the other hand put proposals forward and tend to be intuitive and forward with suggestions towards progression of the entire entity.

Now I see why I get the nickname "engineer"

[sMASH]

U are unique, met a few like u... The others... Meh....

A madnah went a German uni fur a project, while he was dojng his PhD in uwi.

He said theur programs and uwi programs are chalk and cheese. In a nutshell, he said there, was more like a research laboratory.
Here, they just gear up to get ah wuk in the oil an gyass.

[nervewrecker]

Im not an engineer, they just call me engineer.

In all fairness they limited to what they can do with this permit to work system. They do answer to someone and a lot of the younger engineers get blows from seniors who downright disregard their abilities or are resistant to change.

Same hurdles I face with men. Sometimes you report something and you get licks for it because someone saying you trying to make them look bad and them is pardners with the person you reporting it to. But you know me, persistent, I will find who wants to hear me and get things fixed. This same discussion came up just last week.

[sMASH]

I met some who were actually interested. But the vast majority just there to get enough money to blow out on the weekends.


Don't blame them tho, cause just as u said, they limited anyways.

[sMASH]

An easy way to kno if cgcl makes its co2 by methane combustion is by seeing if they inject air right after the reformer.

The Temps there supposed to cause the methane to auto ignite in the presence of oxygen.

That gas stream will be very hot, so it then would go to a high pressure steam boiler to recover that heat energy.

[nervewrecker]

I does call them paper pushers, because they like to stay in office and hide from sun.

It really is something to see one prompt on response to a problem, outside all the time, checking, double checking and being thorough, early for work till you can set you clock by this person and at the same time polite. Most are stock up and you cant talk to them, I was sold when I heard comments towards some guys installing a toilet. Was actually the same comments I made towards them so even better yet.

Some of the inexperienced ones feel attacked when you try to correct them. Corrected one recently and she got on a high horse like I attacking her.

[sMASH]

U lucky. A time i had to get a hesq signature on a permit, saw the new girl, went to ask and before I could say anyting, first ting she ever said to me was 'I have a husband'.

My head hot wirh trying to organize permits, I didn't kno how to calculate that into the work schedule.

And I dint think I used to look that thirsty.

[nervewrecker]

as we on the topic of carbon and fuel, I saw an ad concerning a plant of some sort in Point Fortin from I think was D2F or D. Rampersad. Mostly mech

Only plant I know down right now is the ethanol plant. But that's for export afaik.

[nervewrecker]

Smash, you make any headway?

I can't find anyone from cgcl right now.

But all I will say is god bless tuner and God bless you sir with your goat mouth. Now, suggest that I should be on a metal structure in the marine environment plz.

[sMASH]

Yes. Link wirh a former coworker In cgcl..
Confirmed they obtain their carbon from the methane feedstock.

So I will continue with my experiment to see how effective it is to scrub co2 from the air.




Now, Just need a gtl P&ID, to figure out the diesel generation part.

Yara gets 10%. What will the PSA do now?
