摘要： PURPOSE: To maintain and improve desulfurizatin ratio in the Takahax desulfurization process, by introducing coke oven gas into an absorption tower and perfoming desulfurization under controlled density of an absorbing solution and gas/liquid ratio.
CONSTITUTION: Coke oven gas 1 is introduced into an absorption tower 2 for absorption of NH
3 , H
2 S and HCN contained in the coke oven gas by an absorbing solution 3 and the absorbing solution is led into an oxidation tower 5 through a circulating tank 4 in the presence of a catalyst. In the oxidation tower, the absorbing solution 3 is brought into contact with air for oxidative regeneration and the regenerated solution is returned to the absorption tower 2. To maintain the ratio of desulfurization especially in summer season, etc., the density of absorbing solution and liquid/gas ratio are controlled through establishment of an optimum desulfurization ratio, measurement or estimate of the temperature of the absorbing solution and determination of the specific gravity of the solution. Thus a decrease in the specific gravity of the absorbing solution and an increase in the liquid/gas ratio make it possible to maintain an effective alkali concentration and prevent lowering of the desulfurization ratio even when the absorbing solution is at a high temperature.

摘要翻译：目的：为了保持和提高Takahax脱硫工艺中的脱硫剂比例，将焦炉煤气引入吸收塔，并以吸收溶液和气液比控制密度进行脱硫。构成：将焦炉煤气1引入到吸收塔2中，用于通过吸收溶液3吸收焦炉煤气中所含的NH 3，H 2 S和HCN，吸收溶液通过循环罐4引入氧化塔5中存在催化剂。在氧化塔中，吸收溶液3与空气接触进行氧化再生，再生溶液返回到吸收塔2.为了保持脱硫比特别是夏季等，吸收溶液的密度和通过建立最佳脱硫比，吸收溶液的温度的测量或估计和溶液的比重的确定来控制液/气比。因此，吸收溶液的比重的降低和液体/气体比的增加使得即使当吸收溶液处于高温时也可以保持有效的碱浓度并防止脱硫率的降低。

摘要： PURPOSE: In the production of ammonium sulfate crystals by concentration of ammonium sulfate mother liquor, the steam formed in the evaporator is pressurized to raise its temperature and utilize as a heat source for the heater whereby the steam for heating is made unnecessary and corrosion of the equipment and local precipitation are prevented.
CONSTITUTION: The mother liquor of ammonium sulfate 1 is sent by pump 11 through crystallizer 2 to heater 3 where its temperature is raised up with steam 4. The hot mother liquor 1 is introduced into the evaporator which is kept in vacuum 5 where water is distilled off, then the concentrated liquor 1' is introduced through the vertical tube 8 into the salt collector 12 which is set at the bottom of the crystallizator 2 where crystalls of ammonium sulfate are fromed and the product is sent, in the form of a slurry, to the following process such as dehydration and drying. In the meantime, the steam formed in the evaporator 5 is introduced through cyclone 13 into the vapor compressor 14 where it is compressed until its temperature rises up to 78.5°C and the steam 4 is fed to the heater 3 to heat the ammonium sulfate mother liquor 1.

摘要： PURPOSE: To perform treatment of waste liquid of high ammonia concn. without pretreatment or dilution by adjusting the concn. of dissolved oxygen in an aeration tank contg. waste liquid of high ammonia concn. to 0.1W0.5ppm and performing treatment with activated sludge for the adjusted waste liquid.
CONSTITUTION: Ammonia liquor having 5,000ppm ammonia concn. is charged to an aeration tank and aerated to 0.3ppm dissolved oxygen. and then subjected to the treatment with activated sludge. As the result, SCN
- is held always at ≤3ppm; the superiority of the performance of the treatment is thus recognized. The control of the dissolved oxygen in the aeration tank is performed by the control of the working number of stirrers in accordance with detection signals issued by a measuring instrument for the dissolved oxygen installed in the aeration tank, or by other means. For the control of the dissolved oxygen, it is desirable to use simultaneously oxidation-reduction potential and pH as the measure for the operation. By this way, treatment of waste liquid of high ammonia concn. is possible without dilution.
