Why do certain oil's need to be recycled separately?

He would then stare at the flame intently, looking for something, and then declare it okay or not okay to pour into their tanks. My oil was never rejected, even when I had gear oil mixed in, so I don't know what that test accomplished or if it was really nothing more than a scare tactic by the recycling facility...

Yep, he must have been an old time chemist. After a while, one can get good at it .....

Quote:

"Flame photometers have a wide variety of applications and are used in clinical, laboratory and environmental settings. Sample purity is an important aspect of using a flame photometer. Typically, laboratory workers calibrate flame photometers before beginning the analysis of a chemical sample. To do so, workers use a series of chemicals called “standard solutions,” for which the proper results are already known. By testing these standard solutions, the laboratory worker can make fine adjustments to the device to ensure that the test results are valid. Many college chemistry courses educate students in the use of flame photometers.

Did those hydrocarbons come from "dinosaurs"?

I am confident that every planetary body in the solar system has hydrocarbons (petroleum) once we look hard enough.

Did Earth's petroleum get contaminated by some biologically active components on Earth? - Sure.
There have not been enough plants & animals alive in Earth's history to explain the vast quantities of the stuff we have found, even if every single living cell had been converted to petroleum.

Petroleum and hydrocarbons were present on Earth FIRST, then came the life.
Not the other way around.

How much of the stuff have we found, vs how much biomass has there been?

Curious about where you're getting the numbers.

Frankly I dont believe that all Petroleum content comes from Dinosaurs or "plant/animal matter" anyway.

Are you yanking our chain to see if we are pay-en attention, or are you being @justatroll .. ??

Just go ahead and answer the question:
If the liquid hydrocarbons on Earth all originated in Plant/animal matter, then where did the oceans of ethane & methane on Titan come from?

Well, now @justatroll .......... the reported evidence that ethane and methane exist on Titan has been documented fer sure.

How did it get there? I subscribe to the theory that it's is a product of the chemical processing of primordial solar nebula material. I doubt it had a biological origin.

However, here on earth, I buy into the "biogenic theory" (organic origin) for most petroleum.

Now, if you wish to go with the "abiogenic theory" (inorganic origin) of petroleum here on earth …. good luck finding enough to lubricate the engine of your car.

(where is that MEME that says "science bitch" ..... )

Next question:
IF organic materials can concentrate in such massive quantities on Titan from "a product of the chemical processing of primordial solar nebula material" then why wouldnt the early Earth concentrate similar materials in even greater quantities?

This is fun .....

Well, for starters, methane has a melting point of about minus 295 degrees F and a boiling point of about minus 258 degrees F. Ethane is down there also.

The average surface temperature of Titan is roughly minus 292 degrees F.

Now Earth has a average surface temperature of about plus 57 degrees F.

So, if a cow farted on Titan, the methane would hit the ground as a liquid (or solid).

If a methane/ethane lake were on Earth ...... the area around it would smell like cow farts.

You see where this is going .......


What the hell WAS this thread about ??.........

Methane are farts, right?

Yeah comes from decaying bio matter. But also exists without this occurrence

Ahhh the old interstellar oil debate.
AGAIN!

Well, largely, yes.

If you had ever milked a cow (by hand), on a cold winter morning and had her tail clamped behind your knee (so she wouldn't swish you in the face) and she let out a big fart ..... you would know what methane smells like ......

Sorry ...... I did it again .....

Well sir you need a thread about your stories back in the days
