Steam Heated Chlorine Evaporator

Description

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. This 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 re-liquification 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

This Evaporator is designed to self adjust the liquid chlorine level thereby preventing the build up of excessive pressure. An automatic or manual Shut-Off Valve and Pressure Relief Valve, Cathodic Protection, Steam Valve, Condensate Trap, Drain Valve, Pressure Gauge and Temperature gauge is also included for safe operation. We can provide additional accessories in Chlorine Liquid Pipeline, if required, like Expansion Chamber, Pressure Switches, Rupture Disc, Liquid Chlorine Supply Pipeline System with associated Manifolds, Valves etc.

We can also provide additional accessories in Chlorine 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 maintenance. This Evaporator can be made fully automatic or partially automatic depending upon the level of automation and sophistication required by the Client.. The same arrangement with suitable materials of construction is used for Ammonia, Sulphur-dioxide vaporization.
