"I thought that only the removal of the SO2 was impossible by the dry process processing.
At last I found the treatment agent which could be equivalent to the emission control that became severe generally year by year."

As "I gave it up when clogging and an alcohol smell of the plumbing, the evil to facilities are peculiar to an effluent gas treatment agent, original direct is surprised at improvement, the thing that was able to dissolve so."

The reason is the pore capacity 3 times as large as JIS *go*ishihai.

- The pore capacity ： The measurements of the capacity of the pore (pore) which the calcium hydroxide particle by the nitrogen gas adsorption method (the BJH method) has.
- BET ratio surface area ： The measurements of the area of the calcium hydroxide particle surface by the nitrogen gas adsorption method (the BJH method).
- Dynamic appearance specific gravity ： With the value that I calculated than measurements of slack appearance specific gravity and the harder appearance specific gravity, it is approximately equal to the specific gravity in the calcium hydroxide retention tank.
- Average particle size ： Measurements with laser diffraction / dispersion-type particle size distribution measuring equipment (dry process compulsion dispersion mode).

The reason has drug consumption and a decrease of hihaihatsuseiryo to becoming it.

It depends on "paudatesuta PT-N model" made in Hosokawa Micron
1) Dynamic appearance specific gravity (g/cm3)
=(hardening appearance specific gravity - slack appearance specific gravity) X compression degree /100 slack appearance specific gravity
=(hardening appearance specific gravity - slack appearance specific gravity) X compression degree /100 slack appearance specific gravity
2) Compression degree (%)
=100* (hardening appearance specific gravity - slack appearance specific gravity) / hardening appearance specific gravity
=100* (hardening appearance specific gravity - slack appearance specific gravity) / hardening appearance specific gravity
3) Fluid index
The number that expressed easiness of outflow when the powders which stood still began to flow. Generally, cross-linked preventive measures are necessary so that this number is small.
The number that expressed easiness of outflow when the powders which stood still began to flow. Generally, cross-linked preventive measures are necessary so that this number is small.
4) Jet-related index
The number that expressed easy flushing (the difficulty that is up of working powders). Generally, a tendency of the flushing becomes strong so that this number is big.
