    摘要： The present invention relates to a method of cleaning a pressurized container having at least one chemical contained therein. The pressurized container may be any type of container able to store chemicals under pressure. Preferably, however, the container may be a rail tank car. Generally, the method begins with inspecting the container, testing for leaks in the container and verifying the contents of the container. Cleaning the container entails injecting the container with an amount of heated nitrogen gas to commingle with the chemical contained therein. The nitrogen gas/chemical mixture is then fed to a flare for incineration of the chemical. This may be repeated a plurality of times to completely clean the container or reduce the concentration of the chemical therein to a predefined amount. After cleaning with heated nitrogen, the container may be steam-cleaned and opened to remove debris.

    摘要： The present invention relates to a method of cleaning a container having an amount of liquefied petroleum gas contained therein. The container is first inspected thoroughly for leaks. Heated nitrogen gas is then fed into the container. The heated nitrogen gas may be transported from a nitrogen storage tank to the container via at least one pipe. Liquid nitrogen may be fed into a vaporizer for vaporizing the liquid nitrogen. The nitrogen gas may then be heated via a steamer to expand the nitrogen gas and ensure that no liquid nitrogen enters the container. The heated nitrogen gas may vaporize any liquid liquefied petroleum gas contained therein. Further, the heated nitrogen gas may transport the liquefied petroleum gas to a flare for incineration. The heated nitrogen gas may be added any number of times to reduce the concentration of the liquefied petroleum gas therein to a desired level. The container may then be steam cleaned and opened to enter and thoroughly clean or inspect the inside of the container.

    摘要： The present invention relates to a system for cleaning a pressurized container having at least one chemical contained therein. The pressurized container may be any type of container able to store chemicals under pressure. Preferably, however, the container may be a rail tank car. Generally, the system includes the container that may have a plurality of valves for adding or removing gaseous or liquid material to or from the container. The container may be connected with a nitrogen tank that may be heated via a heater. The container may further be connected to a flare for incinerating residual chemical material that may be removed from the container.

    摘要： The present invention relates to a method of cleaning a container having an amount of anhydrous ammonia contained therein. The container is first inspected thoroughly for leaks. Heated nitrogen gas is then fed into the container. The heated nitrogen gas may be transported from a nitrogen storage tank to the container via at least one pipe. Liquid nitrogen may be fed into a vaporizer for vaporizing the nitrogen. The liquid nitrogen gas may then be heated via a heater, such as a steamer, to expand the nitrogen gas and ensure that no liquid nitrogen enters the container. The heated nitrogen gas may vaporize any liquid anhydrous ammonia contained therein. Further, the heated nitrogen gas may transport the anhydrous ammonia to a flare for incineration. The heated nitrogen gas may be added any number of times to reduce the concentration of the anhydrous ammonia therein to a desired level. The container may then be steam cleaned and opened to enter and thoroughly clean the inside of the container.
