Many metallurgical processes require chlorine gas for refining or purification. Klorigen™ chlorine generation systems alleviate the risk inherent with the usage of large quantities of pressurized chlorine gas in these facilities. Klorigen™ systems produce chlorine gas on-demand and under vacuum, eliminating the storage and use of pressurized chlorine gas and the risks associated with chlorine gas currently facing many metallurgical applications. In addition, Klorigen™ systems produce a 15%...
Klorigen™ generators are ideally suited to commercial, municipal or industrial bleach manufacturing, as they are capable of generating the same ultra-pure sodium hypochlorite with the same high quality and 10% to 15% concentration levels as commercial bulk-delivered product.
Chlorine has typically been used as a bleaching agent in pulp and paper mills; however, safety concerns regarding the use of chlorine gas in the industry have recently come under focus. Klorigen™ chlorine generation systems alleviate the risk inherent with the usage of large quantities of pressurized chlorine gas in these facilities.
Klorigen™ systems safely generate the chlorine gas and/or high strength (up to 15%) sodium hypochlorite that is typically used to control biological fouling experienced in cooling water processes in the oil and gas industry. In addition to cooling water applications, Klorigen™ technology is well suited to other oil field applications which include hydrogen sulfide removal, enhanced oil recovery and frac water treatment. Onsite generation allows oil and gas applications to continue using their...
Traditionally, power plants have used chlorine gas as the disinfectant of choice for treating plant cooling water. However, several publicly reported chlorine leakages have raised concern regarding the safety of this practice.
Traditionally, water utilities have used chlorine gas as the disinfectant of choice in their water treatment plants. However, recent publicly reported chlorine leakages and foreign terrorist attacks have raised concern regarding the safety of this practice.
Hydrogen Peroxide as a Replacement for Sodium Hypochlorite
Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution.
H2S + NaOH → NaSH + H2O
4H2O2 + H2S → H2SO4 + 4H2O
Typical dose ratios are 5 parts H2O2 per part H2S or, when...
