in order to remove impurities in crude like salt, dirt and other corrosion agents pre treatment is done.
There are many different/possible ways depending on many factors such as where the source [well] is located in relation to the refinery. Based on that I will give some ideas which I can recall at the moment. 1. By a tank truck from the well site to the refinery. 2. By gathering piplines from several wells, to a larger pipeline to a refinery. 3. By truck and/or pipline to a tanker ship to a refinery.
what is done to plastic material in the plastic factory
cold sterilization can and is done in a soak of Cidex solution (glutaraldehyde) in the medical field. Sterilization can be done with steam, gas, and solutions like Cidex.
This type of modification should never be done on your own.
isolation done with column chromatography fractionation method
Enigma was way before computers, it was done by hand and crude mechanical calculators.

Column 2
A rather crude one, but yes, it could be done.
Crude oil is heated in fractional distillation because different hydrocarbons in the mixture have different boiling points. By heating the crude oil, it is possible to separate the hydrocarbons based on their boiling points, allowing for the isolation of different fractions like gasoline, diesel, and lubricating oils.
it is a petrochemical plant process where heavy waxes are removed from crude oils and reformed products prior to further treatment
Crude oil comes from the reservoir as live crude, containing methane and other lower carbon compounds that are liberated as the pressure is reduced (in the reservoir, in the well, in the separator or storage battery) and the crude is allowed to cool. Dead crude is degassed crude meaning no more gas is likely to be liberated. The volumetric measurement of crude is normally done at "standard conditions" of atmospheric pressure and 60 degrees F, although standards vary.
im not sure it can be done unless you take the column apart.
in adults its done at L3 and L4 or L4 and L5
I think you mean level of the vertebral column is a lumbar puncture generally performed?
To insert a column in Excel you click on the letter of the column to the right of where you would like a new column inserted. When you do that you have highlighted the entire column. Once that is done you simply right click and a menu will pop up. Choose 'insert column' and then you are done. To insert a row you follow the exact same instructions except you click on the number of the row that is below the area in which you need a new row.
