Sodium Chlorate of HHHTech

hhh tech vision

Sodium chlorate is a chemical compound with the chemical formula (NaClO3). When pure, it is a white crystalline powder that is readily soluble in water. It is hygroscopic. It decomposes above 250 °C to release oxygen and leave sodium chloride.

Sodium chlorate is an industrial salt produced from water and common table salt in a reaction with electricity. Manufacturing: Sodium chlorate is produced from two commonly found raw materials: salt (NaCl, sodium chloride) and water (H2O) along with the use of large amounts of electrical energy. The manufacturing process involves the electrolysis of an acidified sodium chloride solution in a specially designed electrochemical cell.Sodium chlorate crystals are then removed and the remaining liquor containing salt, chloride ions and dichromate are returned to the electrochemical cells. The crystals are washed and dried to form the final product. For some customers, the crystals are dissolved in water and shipped as a liquid solution. Uses: Sodium chlorate is largely used by the pulp & paper industry to produce chlorine dioxide, which is used to bleach wood pulp for the manufacture of higher quality and environmentally friendly white paper products. Pulp mills convert sodium chlorate into chlorine dioxide - an environmentally friendly bleaching agent. The process of using chlorine dioxide to bleach pulp is referred to as "ECF" bleaching meaning "elemental chlorine free". Our sodium chlorate is available in two forms: dry white crystal that looks like table salt and clear solution.

Usage of Sodium Chlorate

The main commercial use for sodium chlorate is for making chlorine dioxide, ClO2. The largest application, approx. 95% of the chlorate, is in bleaching of pulp where chlorine dioxide today is the predominant bleaching agent. Sometimes Sodium chlorate is also used as a non-selective herbicide. It is considered phytotoxic to all green plant parts. Sodium chlorate can also used as a Chemical oxygen generation, and sometimes it is used in some aircraft as a source of supplemental oxygen.

Synthesis of Sodium Chlorate

More sodium chlorate producers worldwide have selected HHH Solutions' sodium chlorate technology than any other technology supplier. HHH Solutions is the world leader in sodium chlorate technology for both on-site and merchant facilities. Our sodium chlorate technology is based on our research efforts as well as the experience gained from the design, construction, start up and operation of plants worldwide.The HHH Solutions sodium chlorate electrolytic system consists of electrolyzers, a reactor, a cooler and the inter-connecting piping. When direct current is applied, the hydrogen gas produced displaces liquor and reduces the specific gravity of the electrolyzer and the outlet piping contents. The resultant specific gravity differential between the liquor in the electrolyzer and that in the reactor creates a high rate of circulation. This natural circulation system for chlorate production, which was developed by HHH Solutions, provides the desired flow rate through the cells which is necessary for efficient operation. The heat produced in the electrolyzers is removed by an external cooler, which maintains the electrolytic system at its optimum operating temperature. The reactor is designed to provide the retention time required for conversion of intermediate reaction products to sodium chlorate.
