Abstract
The present invention is directed to a halogen detection and removal system and a method of using the halogen detection and removal system. The halogen detection and removal system may be configured to visually indicate the presence and/or removal of a halogen or halogen-containing compound in a process stream. The halogen detection and removal system may include a container, an inorganic substrate, and a metal composition.
Claims20
A halogen detection and removal system comprising:
- a container;
- an inorganic substrate, the inorganic substrate being porous;
- and
- a metal composition, the metal composition being present on the inorganic substrate in an amount less than about 10 wt. % based on the combined weight of the inorganic substrate and the metal composition, the metal composition having a first lightness value, L1, a first chroma value, C1, and a first hue value, H1;
- wherein, after being contacted with a halogen or a halogen-containing compound, the metal composition has a second lightness value, L2, a second chroma value, C2, and a second hue value, H2;
- wherein after being contacted with a halogen or a halogen-containing compound, the metal composition has a negative hue difference, ΔH, the hue difference being determined by subtracting H1 from H2.
A halogen detection and removal system comprising:
- a container;
- an inlet process stream, the inlet process stream comprising a halogen or a halogen-containing compound;
- an outlet process stream;
- an inorganic substrate;
- and
- a metal composition, wherein when the metal composition reacts with a halogen or a halogen-containing compound in a first reaction, the first reaction forms a metal halide;
- wherein when the metal halide reacts with a regenerative additive in a second reaction, the second reaction forms a metal hydroxide.
A process for detecting and removing a halogen comprising:
- contacting a halogen or a halogen-containing compound with a metal composition, the metal composition being present on an inorganic substrate, the metal composition having a first lightness value, L1, a first chroma value, C1, and a first hue value, H1;
- reacting the metal composition with the halogen or the halogen-containing compound, the reaction of the metal composition with the halogen or the halogen-containing compound forming a metal halide, the metal halide having a second lightness value, L2, a second chroma value, C2, and a second hue value, H2;
- and
- contacting the metal halide with a regenerative additive.
