Diethyl hydroxylamine (DEHA)

Diethyl hydroxylamine (DEHA) is a colorless liquid with a faint odor that is commonly used as an inhibitor and oxygen scavenger in various industrial applications, particularly in the energy sector. It can prevent corrosion and extend the life of metal equipment, such as boilers and pipelines, by reacting with oxygen and other harmful species in the environment. DEHA is also used in the production of rubber and plastics. However, it should be handled with care as it can be toxic and irritant to the skin, eyes, and respiratory system.

Diethyl hydroxylamine (DEHA) is used in water treatment as an oxygen scavenger and corrosion inhibitor. It is particularly effective in high-pressure boilers, where the concentration of dissolved oxygen is high and can cause corrosion and damage to the equipment. DEHA reacts with oxygen to form harmless products, preventing corrosion and extending the life of the equipment. In addition, DEHA is also used as a scavenger of free chlorine and other oxidizing agents, helping to maintain water quality in various applications.

Diethyl hydroxylamine (DEHA) is used in the pulp and paper industry as an oxygen scavenger and as a corrosion inhibitor. The presence of dissolved oxygen in the process water can lead to the oxidation of lignin and other components, which can cause discoloration and affect the quality of the final product. DEHA reacts with oxygen and other oxidizing agents to prevent these issues, as well as to protect equipment from corrosion and damage. It can be used in various stages of the pulp and papermaking process, including in pulp bleaching, paper production, and wastewater treatment.
