R290 Propane and Cooking gas ?!

[Apple]

Hi

I want to know what is the difference between the R-209 and cooking gas ?
and if the R209 is not available I can use cooking gas with a mixture of refrigerant gas, such as R-600 ?

Another question:

What type of compressor oil to use with the R209 ?

:)

Mr. Apple,

What you are trying to do????
Cooking gas is a blend of
methane CH4
propane CH3CH2CH3
butane CH3CH2CH2CH3

and furthur you are adding iso butane means a highly inflammable mixture of gases.

As refrigerant how it will respond that is not clear, although if something went wrong then ??????

Hence you decide as this is a deadly exp. which you are planning.

Thanks

Thank you for your reply Amit,

I have seen the use of this gas and I wanted to make sure it ... w w w. xtremesystems . org / forums / showpost . php?p=3983277&postcount=37

The other reason, because I think that R209 is not available in the UAE!

Hi Aplle.

If you meant R290, it is a clean propane and in some cases, a gas supplier can make you that one if they can give you a certificate for the moisture level low as for the R290. If you talk about R209 so is that a retrofit for R12 normally and not particulary used in my country. You can use R401A (MP39) if easier to get than R209A. They have a certain glide.
Regarding oil, it seems like both can work with all types, but MO mineral is the one which it is best to avoid. Over here, the cooking gas is pure propane and not feeded to the buildings, but a product to buy in bottles. If you have the same as mentioned and the gas supplier makes a good one (Dry), you can use it instead of the R290, but not as a substitute for R209A;) Pedro

I did not understand 100% you mean!
And yes, I mean this type R-290a and apologized for that!

And the R290 is not available in my country and for this I ask if I can use cooking gas mixing with another type of refrigerant gas so I can get the same specifications R290 in the same unit or I can not do so!

Link experience is in the attached file.....

Thank you very much Pedro,

[Apple]

Any advice or other information?

[reply2nava@gmai]

Mr.Apple,

i had gone through your text conversation.I too like to know ,what can be substuite for R290 which is highly flameable gas..
Pls let me known ..

UAE is one of the net exporting countries of petroleum products, and you can't find propane?
R290 = propane, and it is not cooking gas. Cooking gas contains 90-95% of propane, and other gases, including water.
R290 is 99.99% pure propane with less than 50ppm of water.

As a comparison mud is 90% water, but you don't want to drink mud.

Apple.
in a word moisture content.

And smell.

Smell is added to cooking gas so if it leaks you can smell it.
Refrigerants do not have smell added.

This is a new one to me. R290 is used as a sweeper in the ULT's in the US. Cooking propane? Really? Don't use it please!

In one of the retrofit training programs conducted by GTZ, promoting use of HC in refrigeration appliances, they mentioned about this additive added in cooking gas to make it easily detectable when it leaks. They also cautioned that this "smell" additive will kill the hermetic compressor motors, as it is not compatible and reacts with the motor insulation.

50 ppm water concentration is quite high. I recommend looking for R290 suppliers that can provide R290 with a moisture specification less than 5 ppm. Typically, R290 spec is more like 99.5% purity, rather than a 4.0 grade (99.99%) purity typically reserved for ultra high purity or research grade applications.

[NoNickName]

5ppm is grade 2.5.
50ppm is more than suitable for a refrigeration application.

[bfrauenheim]

5 ppm maximum moisture is our spec for 1.5 (95.0+) grade used in aerosol propellants, 2.5 (99.5+) grade for refrigerants and instrument grade applications, and also for 3.0 (99.9+) and 4.0 (99.99+) grades used in high purity and electronics applications. Moisture is effectively removed during the manufacturing process from ALL of these grades. 50 ppm moisture might be OK for refrigerant applications as you mention, but why settle for so much moisture in your hydrocarbon refrigerants? Due to the very low solubility of water in hydrocarbons, it doesn't take much moisture in the system to reach saturation conditions.
