Kemira opens new production line for sodium chlorate

Industrially, sodium chlorate is produced by the electrolysis of a hot sodium chloride solution: NaCl + 3 H 2 O → NaClO 3 + 3 H 2 This reaction progresses in heat (at least 70 °C), and controlled pH . Production of sodium chlorate is by electrolysis of an acidified sodium chloride solution. Purified brine is acidified with hydrochloric acid and sodium dichromate is added to improve cell efficiency and reduce electrode corrosion. The acidified brine is fed to a bank of electrolytic cells.

Production of sodium chlorate

The starting material is NaCl (Sodium Chloride or common salt). Sodium Chlorate is very soluble. About 330 grams NaCl per liter of water is the starting solution. A. Sodium chlorate's main use is the generation of chlorine dioxide for pulp bleaching. Pulp is a key ingredient in the production of paper and cardboard. Sodium Jan 17, 2000 Technology. The manufacture of sodium chlorate involves the electrolysis of an acidified sodium chloride (brine) solution.

The advantage of the series process is that the individual cells can be regulated with respect to temperature and current density for the most economical production of sodium perchlorate. Sodium molybdate—a possible alternate additive for sodium dichromate in the electrolytic production of sodium chlorate January 2007 Journal of Applied Electrochemistry 37(4):499-504 Sodium perchlorate can be used to block iodine uptake before administration of iodinated contrast agents in patients with subclinical hyperthyroidism (suppressed TSH). Production. Sodium perchlorate is produced by anodic oxidation of sodium chlorate at an inert electrode, such as platinum.

HCl is added to this electrolyte before the electrolysis happens. Sodium hypochlorite production equipment starting in 1964 with filtration since 1983 75% of NaOCl in US made on Powell equipment 90% in Canada Significant production in other countries – Brazil, 80% Mexico, 80% Chile, Taiwan, Philippines, 65% Costa Rica, Saudi Arabia and others Chlorine scrubbing and chlorine valve emergency shutoff systems The current world production of sodium chlorate is approximately 3 million metric tons annually and AkzoNobel, with its 14 production sites, is the largest producer with a total amount of about 1 million metric ton sodium chlorate each year. [7] 2.1.1 Process Description Continuous production of sodium chlorate general consist of three main The regulation aims to protect human health and the environment by banning or severely restricting the production and use of persistent organic pollutants in the European Union. Chlorate salt of sodium, sodium trioxochlorate(V), sodium salt chloric acid, chlorate of soda, chlorate of sodium, soda chlorate. Registration dossier . The industrial production of sodium chlorate is one of the largest industrial electrochemical processes both in terms of annual production and energy consumption. Since it is the dominantly applied reagent for wood pulp bleaching, the demand for sodium chlorate is still on the rise with an ever increasing use of different paper products.
