14 Nov 1969TL;DR: In this paper, the authors presented a method of removing sulfur dioxide and/or NITROGEN Dioxide from Gaseous MIXTures.
Abstract: METHOD OF REMOVING SULFUR DIOXIDE AND/OR NITROGEN DIOXIDE AND/OR CARBON DIOXIDE FROM GASEOUS MIXTURES COMPRISING CONTACTING SAID GASEOUS MIXTURE FIRST WITH A MOLTEN NITRATE SELECTED FROM THE GROUP CONSISTING OF SODIUM NITRATE, SOLVER NITRATE AND POTASSIUM NITRATE AND THEN WITH A MOLTEN HYDROXIDE SELECTED FROM THE GROUP CONSISTING OF SODIUM HYDROXIDE AND POTASSIUM HYDROXIDE OR WITH A MOLTEN MIXTURE OF AT LEAST ONE OF SAID NITRATES AND HYDROXIDES.

TL;DR: In this paper, the colorless granular granular coated fertilizer is obtained by coating the granulated fertilizer with a thermoplastic or thermosetting resin, and the colored granular colored fertilizer colored to the different color in every kinds was obtained by dipping the granular coating fertilizer in a coating material prepared by dispersing one or more kinds of pigments in water or an organic solvent.
Abstract: PROBLEM TO BE SOLVED: To easily inform with visual observation that a granular coated fertilizer having different function such as elution period is blended by incorporating a granular coated fertilizer colored to a different color and a non-coated granular fertilizer. SOLUTION: The non-coated granular fertilizer is obtained by granulating a nitrogenous fertilizer such as urea, ammonium sulfate, ammonium phosphate or ammonium nitrate, a phosphatic fertilizer such as calcined phosphate, a modified phosphatic fertilizer or double superphosphatre, a potassic fertilizer such as potassium chloride, magnesium potassium sulfate, potassium bicarbonate, a complex fertilizer such as a potassium phosphate fertilizer or a potassium nitrate fertilizer, an organic fertilizer or the mixture. A colorless granular coated fertilizer is obtained by coating the granulated fertilizer with a thermoplastic or thermosetting resin. The colored granular coated fertilizer colored to the different color in every kinds is obtained by dipping the granular coated fertilizer in a coating material prepared by dispersing one or more kinds of pigments in water or an organic solvent. Next, the non-coated granular fertilizer, the colorless granular coated fertilizer and the colored granular coated fertilizer are mixed.

TL;DR: In this paper, a method for preparing potash fertilizer by using molasses alcohol waste mash is proposed, which comprises the following steps of: absorbing the potassium ions in the waste mash by using modified natural zeolite as an adsorbent; eluting the potassium ion in an adsorbing column by using ammonium sulfate or ammonium nitrate thermal solution to regenerate the zeolites to obtain a potassium-rich solution containing ammonium sulphate and potassium sulphate or amine and ammonium Nitrate and potassium nitrate; carrying out ammonia evolution on the potassium
Abstract: The invention relates to a method for preparing potash fertilizer by using molasses alcohol waste mash. The method comprises the following steps of: absorbing the potassium ions in the waste mash by using modified natural zeolite as an adsorbent; eluting the potassium ions in an adsorbing column by using ammonium sulfate or ammonium nitrate thermal solution to regenerate the zeolite to obtain a potassium-rich solution containing ammonium sulfate and potassium sulphate or ammonium nitrate and potassium nitrate; carrying out ammonia evolution on the potassium-rich solution after cooling; carrying out solid-liquid separation, washing the obtained solid phase, and drying to obtain the finished product of potassium sulphate or potassium nitrate. The obtained liquid phase of mother liquor containing potassium can be used for preparing eluent for next circulation after ammonia distillation, and ammonia obtained by the ammonia distillation can be used for ammonia evolution for the next circulation. The method for preparing the potash fertilizer has simple process and remarkable economic benefit and is easy for realizing industrial production, and the raw materials of the zeolite, the eluent and ammonia can be easily obtained and recycled.
