The role of high pressure flashing gas Absorber was to Absorb the CO2 gas from high pressure flashing steam by NHD solution,the purified gas containing N2 and H2,obtained from recovery,was used as the raw material of synthetic ammonia.

Analyzes the reasons for times of erosion failure of the HP flash drum shell, and presents relative erosion control measures.

In order to purify and obtain high content α-cellulose and increase its reactivity, the natural wheat-straw was modified and treated by steam explosion.

A new aqueous alkalisoluble cellulose was obtained by steam explosion treatment, which can be dissolved completely in the aqueous NaOH solution with specific concentration at 4 ℃.

Aim High-pressure steam explosion treatment was carried out on cellulose (purified cotton linter and wood pulps treated by alkali solution) to study the effect on the super-molecular structure of cellulose.

Not like liquid in other evaporation equipment, does the liquid in the flash evaporation gas removal equipment evaporate by itself ar~d no heating surface is needed.
