| Potassium sulfate crystals are granulated by first preparing a potassium sulfate feed material sized such as it is at least 50% -6 +65 mesh, 10% to 30% -200 mesh, with the remainder being -65 +200 mesh. The sized crystals are wetted to a moisture content of 7 to 12 percent by weight of the crystals. A small amount of a surface active agent such as disodium 4-dodecylated oxydibenzene sulfonate is incorporated in the admixture, and the mass granulated and dried in a rotating, tubular granular drier. Product temperature is maintained below a maximum of 550*F. and the maximum temperature of gases contacting the product is maintained below 1,200*F.

| PROCESS AND APPARATUS FOR THE RECOVERY OF SULFUR DIOXIDE FROM SO2-CONTAINING GASES IN A SYSTEM INVOLVING CONTACTING THE GAS WITH AN AQUEOUS SULFITE SOLUTION TO PRODUCE A SOLUTION OF THE CORRESPONDING BISULFITE WHICH IS A PRECURSOR OF SO2 AND SUBSEQUENTLY SEPARATING THE BISULFITE AND SO2-PARTIAL PRESSURE LOWING MATERIALS TO OBTAIN PURER BISULFITE WHICH IS THEN DECOMPOSED TO REGENERATE SULFUR DIOXIDE. EXAMPLES OF SULFITES INCLUDE POTASSIUM, CESIUM, AND RUBIDIUM SULFITES. IN THE PROCESS SEPARATION OF THE BISULFITE IS ACCOMPLISHED BY VAPORIZATION OF WATER FROM THE BISULFITE-CONTAINING SOLUTION, E.G. IN A FLASH CHAMBER TO SUPERSATURATE THE SOLUTION AND PRECIPITATE THE BISULFITE, E.G. IN AN AMOUNT EQUIVALENT TO THE AMOUNT OF THE SULFUR DIOXIDE REMOVED FROM THE WASTE GASES. CONDITIONS ARE CHOSEN TO PRECIPITATE CRYSTALS HAVING A SIZE SUITABLE FOR VACUUM DRUM FILTERING. THE CRYSTALS ARE ADVANTAGEOUSLY REDISSOLVED PRIOR TO HEATING TO REGENERATE THE SULFUR DIOXIDE AND A PORTION OF THIS SOLUTION IS USED TO WASH THE CRYSTALS ON THE DRUM FILTER AND IMPROVE THE PURITY THEREOF.

| PURPOSE:To obtain an fine particle of an alkali metal compound having low bulk density by bringing an aqueous solution of an alkali metal compound into contact with a combustion gas generated from a specific pulse combustor. CONSTITUTION:An inlet 10 or 11 for an aqueous solution of a raw material is placed at the inside or at the outlet port of the combustion gas-discharging tube 6 of a pulse combustor 1. An aqueous solution of an alkali metal compound such as NaCl, KCl, Na2SO4, etc., is fed through the inlet for an aqueous solution of a raw material and it is brought into contact with pulse combustion gas of about 300-600 deg.C generated from a pulse combustor 1. The alkali metal aqueous solution is instantly dehydrated and alkali metal fine particles having low bulk density such as about 0.2-0.3g/mL and particle diameters of about 10-40mum are formed. The particles are separated from the combustion gas at a dried powder-trapping apparatus 9 of a cyclone-type and the separated particles are discharged from a dried powder-discharging outlet 12. On the other hand, the combustion gas, which has separated the dried particles, is exhausted from a gas exhaust 13. | ||||||

| The invention relates to a method for producing sulphate of potash granulates, wherein 0.1 to 7.5 wt % of a sodium salt selected from among sodium chloride, sodium sulphate, sodium sulphate hydrates, sodium hydroxide and mixtures thereof are added to the sulphate of potash during the granulation process, the percentage by weight being in relation to the sulphate of potash used. In addition, 0.1 to 2.5 wt % of water are added prior to or during the granulation process. The invention also relates to the granulates obtained by said method as well as the use of sodium salts and glaserite and mixtures thereof for improving the mechanical properties of sulfate of potash granulates. The sulphate of potash granulates produced by the method of the invention have significantly greater bursting strength and significantly greater abrasion resistance than granulates known from the prior art. | ||||||

| Apparatus and process for preventing plugging of a reactor used in a system involving reaction between components, e.g. SO2, in a gas and a salt solution, e.g. a sulfite solution which is close to its saturation point, while avoiding substantial dilution of the sulfite solution to produce a spent bisulfite solution from which the bisulfite is subsequently separated and decomposed to release sulfur dioxide. Examples of sulfites include potassium, cesium, or rubidium sulfites. The apparatus includes a reaction zone having at least one, or more contact trays which are sprayed from beneath with the aqueous salt solution, e.g. sulfite solution. An entrainment zone above the trays can be used to advantage and this involves a woven mesh contact material which is sprayed from both sides with the salt solution to remove entrained materials from the gas leaving the reactor. Also, particulate solid or liquid-soluble gaseous contaminants can be removed from the gas before contacting it with the sulfite solution by contacting it with a fluid-permeable, impingement target in the presence of a concurrently flowing liquid stream which is also contacting the target. It is desirable to prevent plugging of the gas inlet opening to the reactor by using a bonnet arranged over the gas inlet opening.
