Industrial Gas Rates

It seems you have supporters to give you the "Yeh"/ thumbs-up on a Good answer when practically you answered nothing!!!!

When I ask a question like that it is obvious i've searched Google first.

$2.40/ Gj > how to convert to mmBtu? or m3/hr? or KWH?

6.8 cents/KWH >how to convert to mmBtu? or m3/hr?

Show me . Don't direct me to Google.

Then please show me formula to calculate steam cost/kg.

(please note this has nothing to do with pipeline transmission or whatever)

Thanks

1GJ = 947817 BTU See here

1GJ = 277.278 KWH See here

All the conversions are listed here

You obviously didn't try very hard with the google search. It took me about 30 seconds to come up with the previous information.

To calculate steam cost/kg boiler efficiency must be known. You have not given that information.

While pipeline transmission won't affect conversion rates, it will certainly have an effect on price which is what you asked for in your original post.

You will find that you will receive much better help here if you show you have put in a little effort.

Fuel Consumption = steam quantity* latent heat / Efficiency * Calorific Value

Efficiency 90%. Does this help.

1GJ = 947817 BTU - Know this . What rate is C$/mmBtu?

1GJ = 277.278 - Know this . What rate is C$/KWh?

So how much is cost steam C$/kg?

Anywhere from ~ $1 - 3 Klb/h...

The simplest way to calculate steam costs is to gather the facility’s cost data, which is site-specific, commercially sensitive and highly unlikely to be had from a global Engineering forum, and divide it by the steam generated over the same period.

It also depends greatly on what one will do with the steam, another fact not evident. Heating a duplex in the winter will be vastly different from autoclaving facilities in a hospital, electric power generation or an atomization processes.

Speaking of boiling water, I think I'll make myself some Earl Grey tea.

OK, let me try a different tack here and maybe this sail can catch wind.

You wish to pay somebody in Canadian dollars for this gas, who? (I don't work for anyone in Canada.)

What do they charge per cubic meter of gas at STP?

How many thermal calories are in that cubic meter?

It takes 540 calories to boil one gram of 100°C liquid water into 100°C steam.

How hot is the water you wish to boil?

How hot do you need your steam?

Cost Natural Gas is $2.40/ Gj

My question: > how to convert this $2.40/Gj to C $/ mmBtu? orC$/ m3/hr? or C$/KWH?

6.8 cents/KWH \

My question >how to convert to this $0.68 cents to C$/mmBtu? or C$/m3/hr?

I find all my old Gurus just giving me diplomatic and political answers.

I am giving you all the rate Natural Gas in Giga Joules as C$2.40 / Gj and

$ 0.68 /KWH

YET NONE is converting it to C $/ mmBtu? or C$/ m3/hr? or C$/KWH?.

Don't send me conversion factors/ tables JUST let me know what $ rate it converts to in mmBtu/ m3/KWH if you can.

I've done my calculation and just wanted to double check but so sorry to find my most over 1.4 decade friends giving me toally merry-go-around answers. So sorry.

PWSlack if you dont't understand the English or my question stop beating around.

If cost is $2.40/GJ and 1 GJ = .947817 MMBTU then cost per MMBTU is $2.40/.947817 = $2.53 per MMBtu. If your boiler is about 90% efficient then $2.53/.9 = $2.81 per MMBtu.

You still don't give enough information to give an exact answer but making some assumptions on feed water pressure and assuming 10,000 kg/hr of saturated steam, we can estimate about 22 MMBtu/hr or roughly $62 per hour.

Troy,

My old friend BIG thank you.

COST OF GENERATING STEAM@ CANADA 2020:

22,000 lbs/hr (10,000 kg/hr) at 150 psi

150 psi > 1195 Btu Enthalpy

Feed water 90C > -162 Btu

= 1033 Btu/.90

= 1147.8 Btu at 90% efficiency

Calorific Value Gas 1000 Btu

Rate 2020: $ 2.53/mmBtu

22,000 x 1147.8/1000 = 25251.6 Cft Gas required

MmBtu = 25251.6 x 1000/ 1000000 = 25.25 mmBtu

Cost Gas / mmBtu = $2.53 x 25.25 = $63.88/22,000 lbs

= $0.0029/lb Steam

= $2.90/1000 lbs Steam

= $6.39/Ton Steam

=$0.0064/Kg Steam

Please check if OK.

Thank you again.

That looks about right to me, but I am no expert and it really isn't my field so if this is something critical or really important I would have someone you know you can trust check the numbers.

Thank you Troy you've always been helpful.

Same old friends others too but possibly with age they've become sarcastic. Very sad.

None of it takes into account the maintenance and depreciation costs of the installation.

Because all of this is installation-specific, and financial information is commercially sensitive, this is why this forum deals with technical issues, leaving finance ones for processing by the facility in question instead.

This information can be obtained by contacting the gas suppliers in those districts directly. The correct tool to use is the telephone.

Thanks. How silly of me i may be living in a jungle and did not know that?

Actually most of my old friends retired from engineering calculation and this is one of the reason I left CR4 for over 2 years and find nothing has changed. Thanks and no thanks for your political answer.

The forum does not have the telephone numbers in question nor the incentive to make the calls.
