Chlorine Unloading
Powell can supply the required components for a complete chlorine unloading system
designed in accordance with The Chlorine Institute, Inc. Pamphlet 57 guidelines.
The system could include
chlorine transfer hoses, chlorine
pressure gauges, automatic and manual
ball or
plug valves of Monel® or Hastelloy® C,
expansion tanks, and required accessories.
Our complete continuous process systems integrate, and interface with, all process
components, including chlorine tank car unloading systems with chlorine detectors,
chlorine scrubbers,
chlorine tank car padding systems, continuous bleach plants, bleach filter systems,
bleach dilution systems, and all automatic process controls including
tank level control systems.

Powell has combined high quality chlorine-rated components with the latest design
recommendation from The Chlorine Institute, Inc. Pamphlet 57 into a single unit.
Chlorine Control Module

The Powell Chlorine/Sulfur Dioxide Eductor is suitable for use in liquid and gas
applications and was developed to safely evacuate chlorine or sulfur dioxide cylinders,
tankers, rail cars, and piping systems. The unit is based on a unique manufacturing
concept, and is custom sized for each application. Sodium hydroxide is typically
used for the motive liquid.

Railcar Unloading
System (Padding System)
The Powell Railcar Unloading System provides an independent source of clean, oil
free, dry air in accordance with The Chlorine Institute, Inc. Pamphlet 66 guidelines
for chlorine tank car pressure padding. This separate chlorine padding system is
completely isolated from other air supplies to prevent chlorine vapors from accidentally
mixing into the instruments and equipment. Built in redundant features protect equipment
in the event of power loss, compressor failure, or failure of individual components.
The standard Powell Railcar Padding System incorporates an air padding compressor,
air drying system, and backflow prevention sub-assembly mounted on a skid along
with a control system housed in a NEMA 4X box.
Railcar Padding System
A subassembly in the Powell Tank
Car Padding System is available as an individual assembly. The unit is designed
to prevent the back flow of chlorine from the tank car to the air drying system
and to automatically fill the tank car. Redundant features are built in to maintain
equipment protection in the event of power loss, compressor failure, or failure
of individual components.
