The Snamprogetti Urea Process Description
The Snamprogetti Urea Process is basically a total recycle stripping
process using ammonia as self stripping agent. The Snamprogetti process
used the excess ammonia present in the urea solution leaving the reactor
to strip CO2 from urea solution in a falling film steam heated heat exchanger operated at the urea reactor pressure. The separated CO2 and NH3
are recombined as ammonium carbamate in...

Types of Agitators
Propeller agitators
are commonly made of three bladed attached to the main shaft. They are
flexible in operations and mostly used in mechanical mixing of low to
medium viscosity fluids. These type of propellers are also called as
marine type propellers. The diameter of the propellers depends on the
rotational speed and diameter of the batch reactor or the agitator
vessel. Depending on the agitator vessel size...
Industrial agitators are machines used in industries that
process products in the chemical, food, pharmaceutical and cosmetic
industries, in a view of :
mixing liquids together
promote the reactions of chemical substances
keeping homogeneous liquid bulk during storage
increase heat transfer (heating or cooling)
They are devices used to stir or mix fluids, liquids specifically.
Types
Mainly 4 types of Agitators are used in Pharmaceutical...
This is an Overview about annular BOP (Hydrill).
Here, I am showing the description of hydrill and its parts by images.
this is the image that shows the internal building of hydrill,
and this is another model for annular
· Using a spherical rubber sealing element.· Low one-piece height to save installation space.· Large volume of spherical rubber sealing element, long service life.·
Wide sealing range, BOP can seal different sizes...
