Chlorinated
hydrocarbon solvents are greatly used in dry cleaning, metal degreasing a great
range of solvent extraction procedures in the chemical plants. When water is
eliminated and at natural temperatures, the solvents are not attacking and
steel equipment can be used to deal them. However of entrained water or water
layer and specifically at the elevated temperatures that occurs in distillation
and recovery of solvents, the essential hydrolysis with development of dilute
hydrochloric acid.
The development
of acidity is increased by nominal light and aeration. The steel is sharply
attacked. For a great service of numerous years, Monel 400 and Nickel have
offered supreme resistance to corrosion in these media of a great range of
chlorinated hydrocarbons. The alloys are utilized for distillation and recovery
equipment in the development and application of solvents.
In the
development of chlorinated solvents while their development, the corrosive
conditions are very vigorous in the static media or reboiler in the edge parts
of distilling columns where water accumulates. Monel 400, Nickel and Inconel600 wire provide high resistance to corrosive media, these alloys are used for
distillation and recovery equipment in the development and service of solvents.
An evaluation of
resistance offered by metals and alloys to corrosion by different chlorinated
solvents and mixtures of the solvents with water at room and boiling
temperatures. In the refinement of
chlorinated solvents while their development, the corrosive media are harsh in
the static or reboiler or in the edge segments of distilling columns where
water deposits. It is discovered by the results of plant corrosion evaluation
in regular process for refinement of crude carbon tetrachloride.
The main
applications of Monel 400 and nickel are in the development of dry cleaning
systems, for components need in solvent recovery stills and condensers, washer
cylinders, water distillation, lint traps and solvent storage containers. These
equipments use a wide range of solvents like carbon tetrachloride,
trichloroethylene, perchloroethylene and solvent mixtures.
For metal
degreasing applications, various chlorinated solvents are used including
trichloroethylene, carbon tetrachloride, perchlorethylene, ethylene dichloride,
propylene dichloride and more. Monel 400 and Nickel are used for degreasing
containers and solvent recovery equipments.
In the solvent
use of animal and vegetable oils, various chlorinated solvents are used. Monel
400 is used for solvent recovery equipment for cod liver extraction using
ethylene dichloride.
A large count of
organic chlorination is in the set of dry raw materials. For organic
chlorination, Monel 400 and Inconel 600 are used. They offer good corrosion
resistance and have no catalytic influence on the color of the product.
