TWO QUICK JARGON LESSONS
We gotta cover some jargon so it will be easier to pick up what Your Mentor is puttin' down.
INSTRUCTIONAL AID JARGON LESSON ONE:
PROCESS TEMPERATURE
MEANS “THE TEMPERATURE OF THE FLUID OR STUFF
THAT IS FLOWING THROUGH THE PIPES"
IN AN IMAGINARY PROCESS
Henceforth, the phrases “process temperature” or "process stream temperature" will be substituted for the wordy phrase “temperature of the fluid/stuff that is flowing through the pipes.”
Real Process Operators actually don’t use the phrase “process temperature."
That’s because Real Process Operators know the actual name of the fluid flowing through the pipes and are more likely to radio in to the control room something that identifies the fluid and where the outside Process Operator is located.
So the message would sound more like:
“TI #2, which monitors the inlet temperature of naphtha to Vessel V-220..."
Okay.Your Mentor just lied:
Real Process Operators don't ever use precise English as inferred in the above example; they use more verbal-shorthand jargon which PTOA Readers and Students will learn.
As an instructional aid, the term "Process Temperature" means "The temperature of the stuff that is flowing through a pipe."
Anyway ...
the term “process temperature” is very useful as an instructional aid when the fluid/stuff flowing through the pipes is unknown or unspecified.
In summary ...
The PTOA Department of Redundancy Department posts the following bulletin:
The terms process temperature and process stream temperature mean “the temperature of the unknown fluid or stuff flowing through the pipes."
Got it?
Yes Indeedo!
Yo comprendo!
INSTRUCTIONAL AID JARGON LESSON NUMBER TWO:
PROCESS FLUID and PROCESS STREAM
MEAN “THE FLUID/STUFF FLOWING THROUGH THE PIPES”
IN AN IMAGINARY PROCESS PLANT
"Process Fluid" and "Process Stream" mean "the fluid that is flowing through the pipes."
Henceforth, the phrases "process fluid” and/or “process stream" will be substituted for the wordy phrase "the fluid that is flowing through the pipes" in an imaginary process plant.
And, heck!
Soup is heated up on a stove. Some of the soup stays in the liquid form and some changes state into a gas. Both the liquid and gas are FLUIDS.
This is as good a time as any to clarify that there are two types of fluids:
liquids and gases.
The phase "process fluid" can refer to either a gas or a liquid.
No doubt some of the PTOA Readers and Students that got a point or two knocked down on a science test in middle school or high school are wanting to protest because they remember:
Pure gases don't occur naturally...there are always liquid particles entrained ... and the proper term for such a substance is the word "vapor."
Righteeo!
All process gases discussed in the PTOA are really vapors....gases with entrained liquid particles.
PTOA is still going to use the phrase "gas" instead of "vapor" because the process industries do not use the term "vapor."
This is a GT ... a Gas Turbine
Process industries use terms like "Fuel Gas" and "Off Gas" and "Gas Turbine" and "Gas Compressor" and so will the PTOA.
I mean who has ever heard of a "Vapor Turbine?"
And one little last piece of jargon:
When the stuff flowing through the pipes is not all in the gas or liquid form but rather a mixture of components in mixed phases, then the phrase "process stream" will apply.
Again, these phrases will not be heard while working at any plant because these phrases are just extremely helpful instructional aids.
The PTOA Department of Redundancy Department posts one more bulletin:
When PTOA Readers and Students read the phrase “process fluid” or “process stream,” they should Imagine the nearby picture of random pipes that have some unknown gas or liquid ... or mixture of gas and liquid ...flowing through them.
That’s all you can do ...
because unless Your Mentor identifies what kind of fluid it is (liquid, gas, vapor, semi solid) ...
you just won’t know otherwise!
Take Home Messages: If you understand the following statement then you understood the take-home messages of this PTOA segment:
"Process Operators vigilantly monitor whether or not the process temperature of the process stream is where it is expected to be."
