How Much of Gas is Required to Produce PMT of DRI

04/17/2011 3:25 AM

Constituents

Coal Bed Methane [Mole %]

Methane 96-98

Ethane <1

Propane <1

Sulphur (mg/m3) -

Nitrogen 0-2

Carbon Dioxide 0-2

Gross Heating Value (MJ/m3) 35.7

Flame Temperature (oC) 1790

Natural Gas [Mole %]

Methane 95.2

Ethane 2.5

Propane 0.2

Sulphur (mg/m3) 0.6-1.0

Nitrogen 1.3

Carbon Dioxide 0.7

Gross Heating Value (MJ/m3) 38

Flame Temperature (oC) 1960

given above are the data for the gases ,would request you to please let me know the amount(in tone) of them would be required to reduce iron ore of fe grade 62,64,65 to produce a tonne of dri.

Do let me know if we use coal to produce synthesis gas then how much of coal would be required to meet the required gas for per tonne of dri.

please let us know the process also.

It will be good if Indian scenario is taken for calculations.

Bad Acronym Alert--"pmt", "dri"?

Well PMT is easy - like every bloke with a female in his life knows that one.

And 'gas' and DRI is either

A. Death Row Inmate

or

B. Dirty Rotten Imbeciles (band)

"Bad Acronym" really?

U just picky U are!

I'm not the OP, but I'm fairly certain "dri" is direct reduced iron, and "pmt" is per metric ton.

Spoil sport - 'rule #1' is define acronyms at first use - or a great deal of time is wasted on 'ass-u-me'.

Sorry, I guess I'm too impatient (in some ways). (And sympathetic to people who's first language doesn't appear to be English, or just don't know how to ask questions.)

Thinking out loud, it might be nice for CR4 to have a very visible link titled something like: "Advice if you're a first time poster here."

(Maybe they have one, either I forgot, or it is not visible enough. ;-)

I'm usually quite sympathetic to ESL posters. Don't even mind the text crowd. But it wears a little thin when acronyms are used for key terms and/or a specific field, or application is unclear.

As it is it can take 30 posts to find out what they really need solved - this needlessly prolongs that 'time drain'.

Also it seems to me, many times they may not know what the acronym actually means, as if they did type it out in full - into google - they'd find the information in less time that writing the post.

True, and Admin could add a "first time poster advice" link, in this window, to a paragraph on the "rules" page. There's space. Could be two birds with one link.

All very appropriate, but OP shows 46 posts to his avatar, so certainly not a first timer. But I like your "baa", very sheepish ("bad acronym alert")....

"... have a very visible link titled something like: "Advice if you're a first time poster here."

Just below the name of the user is (Number of) "Posts:". If it says 1, this is almost certainly the first post from the user.

There are a number of CR4 members, 2-3 years, with several hundred posts who are ESL users, and they still have a tough time asking a cogent question (this due to the language barrier). These users, as well as the new members, get harassed because of incorrect or poor sentence structure. Sad, this.

I guess that note could go on to say something like: "Feel free to review these notes (for first time users) often, especially if you are not a native English speaker.

Yes.

Well, I guess we could...

Like 34.5, I do not worry too much about an ESL poster and their sentence construction. English is a difficult language. Were this a Spanish or German language forum, I might post once in a while. Any language other than these three, and I would not have a chance.

As long as I can get the gist of the question, I just go with it.

It is sometimes shows quite a interesting perspective of the members.

- One who knows

- The others well...

"amount(in tone) of them would be required to reduce iron ore of fe grade 62,64,65 to produce a tonne of dri"

Anyone in the field of iron ore processing would have guessed DRI (also called sponge Iron) PMT was not so easy, but only one sympathetic member had pointed it to be per metric tonne, and that will be corroborated by the gist of the post.

Of course we would then ask what is Fe or what is the meaning of Fe Grade?

We do need some introspective. The members come here to help and get helped. I am sure the member in question (OP) too had been helpful to others in his field.

If we continue in this vein, there will not be too many technical queries and we may start asking the expansion of ASME, which of course the PED users may in future be unaware. (Since one is not going to ask for the ASME, I am not giving the expansion of PED).

There are threads for this type of discussions (BBT- expansion withheld- comes immediately to mind)

Do we know the process of reduction of ore into sponge iron and the requirements? (I dont). If not, the thread is not for us. Let it be addressed by some-one who knows.

But we don't only do that, we call the OP back from the other thread and ask him to meander through this aimless one.

Why ?

Of course OP should have been a bit specific (and may be posted it in the metallurgy section) most of the expert will first visit there. Also the advise there had been appropriate (send a personal mail to the person and then you can get the deleted website/ email address)

On second thought the moderator could have of course advised the OP while deleting the address.

have I ruffled feathers ? Of course yes.
