Although no two Chlorine Loading solutions will be identical, the product itself determines much of the critical design criteria that will ensure that optimum safety and productivity can work together in harmony.

In the United States, chlorine is a “tight-fill” (closed-loop) loading operation and is loaded into trucks or railcars via chemical hoses or by-pass arms. Chlorine, if not handled properly can be fatal and Personal Protective Equipment (PPE) is required. Additionally, because operators are on top of the vehicles during the loading process, fall prevention is essential, not only for safety but increases throughput.

Chlorine tank cars are top un-loaded by increasing the pressure in the vapor space above the liquid level to force the chlorine up the discharge pipe and out the liquid angle valves. Connections to the Angle valves are typically made from one-inch schedule 80 carbon steel pipe, approximately 15” long with standard NPT threaded ends. Additional padding (increasing the pressure in the vapor space) with compressed dry air or nitrogen can be used if the tank car pressure drops during the unloading process.
