A method includes electrolyzing water into hydrogen, combining the hydrogen with nitrogen to generate forming gas, delivering the forming gas to a reducing environment zone, and processing an intermediate material into a product material in the reducing environment zone. The step of processing the intermediate material into the product material may include processing a glass melt into a float glass ribbon on a tin melt and then cooling the float glass ribbon into sheet glass.

An audio speaker having a speaker housing surrounding a back volume that is divided into a rear cavity behind a speaker driver and an adsorption cavity separated from the rear cavity by a permeable partition, is disclosed. More particularly, the adsorption cavity may be defined between the speaker housing and the permeable partition, and may be directly filled with adsorptive particles to adsorb gas during sound generation. The permeable partition may allow the gas to flow between the rear cavity and the adsorption cavity, and may retain the adsorptive particles within the adsorption cavity. Other embodiments are also described and claimed.

The invention relates to a method for separating chlorine from a gaseous anode outlet stream mass flow of an electrochemical cell reactor. In a first aspect, the method makes use of an absorption step, wherein an anode outlet stream mass flow of the electrochemical cell reactor is exposed to an organic solvent being essentially immiscible with water for achieving an exergy-efficient separation of chlorine and hydrogen chloride. In a further aspect, the method makes use of absorption step, wherein the anode outlet stream mass flow is exposed to an ionic liquid, wherein the hydrogen chloride is dissolved in said ionic liquid, thereby forming a gas flow containing essentially chlorine and a solution mass flow comprising the ionic liquid and the hydrogen chloride. The hydrogen chloride is desorbed from the solution mass flow in a desorption step. In another aspect, the method makes use of a distillation step, wherein the anode outlet stream mass flow is separated at a static pressure of at least 2 bar for an exergy-efficient separation.

This invention discloses a decontaminating column for on-line replacing adsorption material, and it includes: a tank having an inner tank being used for filling the adsorption material, and one end of the tank being set to be opened; at least one discharging part is being attached to the tank, and an open-close unit by which the adsorption material can be discharged and which is installed between the discharging part and the tank. There is a chamber in the discharging part, which is connected to a gas replacement unit. At the same time, this invention also discloses a glove box. Compared with the existing technology, this invention effectively solves the problems of low efficiency, high manufacturing cost and high maintenance cost generated by decontaminating column replacement mode in the existing technology; In addition, when the decontaminating column is used in the glove box, replacing the adsorption material can ensure that the water oxygen in the glove box is prevented from leaking out and/or the water oxygen outside of the glove box is prevented from penetrating into the box.
