Chlor Alkali Anode & Equipment's f

DESCRIPTION: The electrolysis of a solution of an alkaline chloride, such as brine (NaCl), has been widely utilized as a method for producing chlorine and caustic. The sodium ion travels to the cathode during the process, such that sodium hydroxide (NaOH) and hydrogen gas are produced at the cathode. The chlorine ion travels to the anode and gaseous chlorine is evolved, although a small portion of the gaseous material may become dissolved in the brine solution. Brine may be continuously supplied to a chamber or cell at the zone of the anode and caustic may be continuously withdrawn from the cell at the zone of the cathode. At the same time gaseous chlorine and hydrogen may be separately withdrawn overhead from the cell. In modified cells which employ mercury, the mercury acts as a cathode ... [More]

Anode and Cathode Coating: The key components of all electrochemical processes are the electrodes and, in some cases, the separators. The last century has seen many developments in both for the electrode materials and ion permeable membranes and allows successful implementation of many novel concepts. Where optimum performance of electrode material is needed, electrodes made from noble metals or noble metal oxides are the components of choice. The common features of the materials of electrodes are   a)        The use of the platinum group and there oxides as coatings on             inert substances. b)        The minimization of platinum metal loading...

  Introduction:  The cathode and anode ageing is another problem and replacement cost is also very high. Reminding both causes i.e. increasing cathode and anode life and decreasing cell voltage; anode side and cathode side coating is generally done. In presents the need, factors affecting and methods for applying cathode and anode coating is highlight with latest development in this zone. It is expected that the study will help to understand the anode and cathode coating in details manner in Chlor-Alkali Industry and modification needed in this zone. The objective of the study is given below:   1.      To see the various causes of the failure of electrode coatings. 2.      To discuss the effective coating process. 3.     ... [More]

Electrochemical importance of Anode and Cathode Coating in a Membrane Cell in Chlor Alkali Industry   Abstract Membrane Cell operation for the production of Caustic and Chlorine is the latest environment and energy friendly process for a Chlor-Alkali Plant. The membrane cell consists of Cathode (Nickel), Anode (Titanium) and a floro carbonated membrane. By the continuous process and process requirement in energy point of view in a normal running Chlor-Alkali Plant, Anode and Cathode coating is required in order to increase more lifetime and more productivity for a cell. This anode and cathode coating not only increase the total productivity of a Chlor-Alkali Unit but also can decrease the fixed cost for a unit by increasing process reliability. ... [More]

Concept Zero Gap Technology totally removes theohmic drop related to ionic movement through the Catholyte gap, by installation of a package of…Cathode screen which is used as current collector. A fine cathode screen shifts up to gently touch the membrane. In between them, durable elastic element is inserted, to transport electrons by contact from the current collector to the fine cathode screen, and capable of compensating for mechanical tolerances with no harm for the membrane.  Zero Gap Retrofit main features Zero Gap has a great opportunity for Power Saving, typically 8-10% lower consumption than original figures Zero-Gap MUST be based on top quality components To overcome the risk of corrosion during shutdown To prevent mechanical stress and damage of the membrane by a gent...
