Caustic Recovery Plant Manufacturer
Mercerisation is a finishing process in textile industry where the
textile fibers are treated under tensile stress with caustic soda. Large
quantities of diluted caustic soda (weak lye) are come out as a waste product of
this process. Caustic Recovery Plants (CRP) can turn a very extensive
proportion of weak lye into reusable concentrated caustic soda (strong lye).
For the diverse requirements of our valued clients, we manufacture and
supply the finest quality batch of Caustic Recovery Plants. Developed in
consonance with the quality standards, these plants are manufactured using
premium quality raw material and advanced technology.
SVAAR is a leading Caustic
Recovery Plant Manufacturer actively involved in developing advanced
turnkey solutions for a multiple range of industrial domains. Our expertise
combined with updated technical hardware machinery and manufacturing unit has
built up SVAAR as probably the best supplier of advanced turnkey arrangements.
The caustic recovery
plant designed and developed by us is predominantly a multi-effect evaporation
plant. In the process of caustic recovery, the caustic soda is re-concentrated
by heating it in a heat exchanger.
Further, when the lye
reaches the evaporator, a significant amount of vapor is released as a result
of water evaporation that eventually increases concentration.
How
it works?
At low
concentration is caustic is heated up to its boiling point. The vapour that is
created due to the before mentioned process is then used to heat the liquor.
The hot liquid is flashed at low pressure and created vapour is used again.
Benefits of a Caustic Recovery Plant
Depending on the requirements of the process, machine re-concentrates
the weak caustic lye.
·
For make-up and concentration variation purposes, the
process uses only fresh caustic.
·
The energy generated from the steam can be
converted in to hot water.
·
Cost-effective as far as neutralizing agents and
water treatment cost is concerned.
·
Sustainable for industrial use.
·
Enhanced performance and minimum maintenance.
Applications
: Caustic Recovery Plant
Under caustic
recovery plant system, Caustic concentration has many applications in
every industry where dilute caustic is formed due to washing and the
concentrated liquor can be reused in various applications where caustic is
reused are:
1. Knit Mercerizing
They have very few impurities such as size and starch, and hence the
recycled caustic is also pure. The recycled caustic can be reused for a longer
period before the cumulative impurities reach unacceptable levels.
2. Grey Mercerizing
Grey knit mercerizing has lot of size in the weak liquor and thus the
recycled caustic has to be replaced often say once in 15 days. The recovered
caustic state viscous & lower gpl has to be conduct to make it usable. To
maintain its gpl this recovered caustic has to be dossed again with fresh
caustic.
