    Eastman | Diethylaminoethanol

    Product description. Diethylaminoethanol (DEAE) is a clear liquid. It is used as a neutralizing amine for boiler water, coatings, etc. Diethylaminoethanol (DEAE) is used as neutralizing agent and CO 2 scavenger in boiler water. The ideal vapor pressure and vapor-liquid distribution properties of DEAE make it the best choice for pH adjustment of process water.

    Water treatment of steam boilers

    Aug 02, 2015 · DEAE: it has a VLDR between that of Morpholine and cyclo hexyl amine. It is a good choice for moderate length condensate line. The low boiling point of DEAE + water mixture makes DEAE suitable for low pressure boilers as well as high pressure boilers. Cyclo hexyl amine: it has a high …

    Water Treatment Requirements for Low and Medium Pressure

    Apr 27, 2015 · The definition of low and medium pressure is somewhat discretionary. For the purposes of this discussion, low pressure shall apply to boilers up to 150 psig. These boilers are typically used in space heating applications where the percentage of return condensate is high. Medium pressure boilers fall in the range of 150 to 650 psig.

  • neutralizing amine use in hospital steam boilers

    Neutralizing Amine Use in Hospital Steam Boilers

    Hospitals use steam boilers to meet a variety of needs including domestic hot water, space heating, food preparation, sterilization, and humidification. The use of water treatment compounds called “neutralizing amines” can be a source of confusion, especially where plant steam is used for humidification and sterilization. Recently updated standards provide clear guidance on neutralizing

    Cleaver-Brooks | Reference Center | Boiler Basics | Steam

    High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the same temperature. Steam and hot water boilers are defined according to design pressure and operating pressure.

    ppb level were observed. Such situations apply to high-pressure boilers where all volatile treatments are used. As the level of dissolved oxygen after deaerator is so small, the acetic acid level will also be correspondingly very low indeed. However, the presence of acetic acid does not mean that it is only originated from DEHA.
