alkaline process

The removal behavior of mineral elements and ash in wheat straw during alkaline pulping is studied by means of atomic absorp-tion spectrometer and SEM-EDAX.

用原子吸收光谱法、SEM-EDAX法研究了麦草原料灰分及矿质元素在碱法(制浆)过程中的脱除规律。

The removal of the mineral elements in wheat straw during alkaline pulping and the effect of those mineral elements on the alkali recovery process were researched by means of SEM-EDXA and atomic absorption spectrometer.

用SEM-EDAX法、原子吸收光谱法探索了麦草原料矿质元素在碱法(制浆)及碱回收过程中的转移规律。

The alkaline pulping black liquor obtained from different processes and different technical conditions was got through the lignin separator which was specially designed.

讨论了木质素分离机在造纸厂的工业性应用，来自碱法(制浆)不同方法、不同工艺条件的黑液通过专门设计木质素分离机，获得纯度达８０％左右的工业木质素（对非木材原料），其分离液清，黑液的ＣＯＤ去除率达６０％～８０％。

In the alkali oxygen pulping of rice straw, concentrated black liquor from a previous cook is recycled and reused.

稻草的黑液循环氧碱法(制浆)在保证获得稳定的制浆质量的前提下，可使碱浸渍黑液和氧气蒸煮黑液的固含量分别提高到１６％和１１％左右，且氧气蒸煮黑液可省去脱硅处理。
