PERFECT CHLORO SYSTEM
manufactures
Evaporators for Chlorine,
Sulphur Dioxide and
Ammonia.
The capacity ranges are from 20 kgs/hr
to 1000 kgs /hr. Evaporators are classified
into two categories depending on type
of energy used for vaporizing, namely
1. Electrically heated Evaporator.
2. Steam heated Evaporator.

ELECTRICALLY HEATED CHLORINE
EVAPORATOR |
Chlorine
is used
in various industries for diversified
applications. Chlorine is generally
stored in liquid form in Ton containers
or Cylinders. Generally, Chlorine
gas withdrawal rates from these containers
do not exceed the vaporization rate
(normally it is 7 to 11 kgs/hr at
around 28 deg Celsius ). Evaporators
are used where large quantity of chlorine
gas is required.
WORKING PRINCILE
he Evaporator
is divided into two Cubicles , the
Inner Cubicle and the Outer Cubicle
. Chlorine liqiuid is transferred
directly from the source
to the Inner Cubicle
by container pressure. This Inner
cubicle is |
|
immersed in a thermostat controlled
hot water bath,which increases the
temperature of chlorine causing it
to boil and vaporize. Chlorine liqiuid
enters the Inner Cubicle and maintains
the required level necessary
to meet the vaporization rate for
gas demand.
Automatically, a change in
gas demand wil cause
the chlorine liquid level
to asjust. The gas thus released is
superheated as it passes through series
of baffles while leaving the
cubicle Generally, a superheated gas
is required to prevent scale formation
of chlorine in the process lines.
|

INSTALLATION
The Evaporator
should be located to the sourse of
chlorine. The length of the chlorine
gas and liquid chlorine pipelines
should be as short as possible. All
the safety equipments should be readily
available and handy. The Plant should
have provisions for exhausting chlorine
gas,if a leak develops. Ideally a
chlorine gas leak absorption system
can be provided for gas leak evacuation
and neutralization. It is recommended
to fix a lifting device above the
evaporator to remove the iner cubicle
for ease in maintenance. Portable
water [pH 7] should be provided to
the System to prevent scale formation
and increase the lifespan of Evaporator
and Heaters.
SAFETY
FEATURES
The Outer
Cubicle, which holds the hotwater,
is protected against corrosion by
two sacrificial anodes. These anodes
being the most active material suffer
corrosion, while the cubicle metal
remains unaffected. In other words,
the Outer Cubicle has Cathodic Protection.
This Evaporator
is designed to self adjust by maintaining
the liqiuid Chlorine level in Inner
Cubicle. The Evaporation rate is self-adjusting
thereby preventing the build up of
excessive pressure. An automatic or
manual Shut - Off Valve and Pressure
Relief Valve is also included for
safe operation. A Temperature Controller
is provided to automatically maintain
the temperature of water in Outer
Cubicle, so that Vaporisation is continuous
and thus ensuring constant supply
of Chlorine Gas to process.
Proper water
level in the Outer Cubicle is automatically
controlled by a Water Level Controller
,Which automatically opens and closes
a solanaid valve fixed in Evaporator
water supply pipeline. Electric Heaters,
Level Indicator, Temperature Gauge,
Pressure Gauge form part of the accessories.
We can provide
additional accessories in Chlorine
Liqiuid Pipeline,
if required, like Expansion Chamber,
Presssure Switches , Rupture Disc,
Liquid Chlorine Supply Pipeline System
with associated Manifolds, Valves
etc. |

|
| We
can also provide additional
accessories in Chloine
Gas Pipeline,
if required , like
Pressure Relief Valves,
Rupture Disc , Pressure Switches,
Shut-off Valve, Pressure
Reducing Valve, Gas Filter ,
Flow Control Valves, Flow Meter,
Pressure Gauges, Non Return
Valves, Chlorine Gas Supply
Pipeline System, Vent Pipeline,
Chlorine Scrubbers, Chlorinators
etc.
This
Evaporator is designed for reliability
, safety and very little maitenance.
This Evaporator can be made
fully automatic or partially
automatic deepending upon the
level of automation and sophistication
required by the Client. |

HEATED CHLORINE EVAPORATOR |
|
| WORKING
PRINCIPLE |
The
Evaporator is divided into two
cubicles the Inner Cubicle and
the Outer Cubicle. Chlorine
liquid is transferred directly
from the source to the inner
cubicle by container pressure.
The Inner Cubicle is immersed
in a temperature controlled
Steam bath, which increases
the temperature of chlorine
causing it to boil and vaporize.
Chlorine liquid enters the Inner
Cubicle and maintains the required
level necessary to meet the
vaporization rate for gas demand.
Automatically, a change in gas
demand will cause the chlorine
liquid level to adjust. The
gas thus released is superheated
as it passes through series
of baffles while leaving the
cubicle. Generally a superheated
gas is required to prevent reliquification
of chlorine in the process lines. |
| INSTALLATION
|
The
Evaporator should be located
close to the source of chlorine.
The length of the chlorine gas
and liquid pipelines should
be as short as possible. All
the safety equipments should
be handy. The plant should have
provisions for exhausting chlorine
gas, if a leak develops. Ideally
a chlorine gas leak absorption
system can be provided. It is
recommended to fix a lifting
device above the Evaporator
to remove the inner cubicle.
Consistent supply of saturated
steam at recommended pressure,
temperature and flow rate should
be provided for reliable performance
of the steam heated Evaporator. |
| SAFETY
FEATURES |

Evaporator is designed to self
adjust the liquid chlorine level
thereby preventing the build up

Temperature Gauge is also included
for safe operation.
We
