    摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more particular silane based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

    摘要翻译： 本发明提供了一种抑制拜耳工艺设备液液中DSP垢积累的方法。 该方法包括将一种或多种特定的硅烷基小分子加入到液体流体回路中。 这些阻垢剂可减少DSP垢的形成，从而增加流体的通量，增加拜耳工艺设备可以运行的时间，并减少对拜耳工艺设备昂贵且危险的酸洗液的需求。 结果，本发明大大降低了操作拜耳工艺的总成本。

    摘要： The invention provides a method of inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes pre-treating surfaces of the process equipment with one or more particular silane based small molecules. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.

    摘要： The invention provides methods and compositions for inhibiting the accumulation of DSP scale in the liquor circuit of Bayer process equipment. The method includes adding one or more GPS-surfactant based small molecules to the liquor fluid circuit. These scale inhibitors reduce DSP scale formation and thereby increase fluid throughput, increase the amount of time Bayer process equipment can be operational and reduce the need for expensive and dangerous acid washes of Bayer process equipment. As a result, the invention provides a significant reduction in the total cost of operating a Bayer process.
