| 26 | I. Valeev, E. Pavlova, V. Samoilenko, S. Zuev, A. Sedenkov | Apportionment of Northern Section of Lake Krasnoe to Artificial Depositsblems of Soda Ash Production Wastes Accumulation in Northern Section of Lake KrasnoeUp to this day the amount of waste from Crimean Soda Plant accumulated in evaporative accumulator at Northern Section of Lake Krasnoye is nearing 100 million cu.meters. The designed volume of accumulator is 100 million cu. meters. Its filling limit level is +2 m. The designed level was several times exceeded which threatens hazardous situations The waste in the accumulator is mainly sodium chloride and calcium chloride solutions. Total mineralization of those solutions already reached 270 g/m3. The growing mineralization has reduced evaporation intensity 1,5-2 times. Water evaporation from the lake surface was reduced to 13 million cu. meters annually. At the same time total input from soda ash plant, irrigation systems, surface water and rainfall makes 17 million cu. meters per annum. The resulting disbalance between input to the accumulator and evaporation from its surface reached 4,0 million cu. meters per annum and is still growing, reaching even 6,0 million cu. meters in some years, like 2004. |
| 27 | I. Valeev, E. Pavlova, V. Samoilenko, A. Ghebanov, S. Zuev | Apportionment of Northern Section of Lake Krasnoe to Artificial DepositsReturned waters accumulated in Northern section of Lake Krasnoye are wastes from processing of initial mineral resources – Sivash bittern and Balaklava limestone – at Crimean Soda [plant Company. Such wastes due to incomplete utilization of raw materials inherent in Solvay soda ash process contain Na+, Ca2+ and Cl- ions in the form of dissolved salts NaCl and CaCl2. In the first half of 20th century the bittern of Lake Krasnoye contained mostly sodium and calcium chlorides. Before commissioning of Crimean Soda Plant the resources of those salts were written off from registration.By now the problem of classification of Northern section of Lake Krasnoye as an artificial mineral resource deposit became urgent. Substantial resources of NaCl and CaCl2 mineral salts (about 100 million cu.meters) have been accumulated in the lake, and they are fit for industrial usage. Besides, the highest acceptable level of lake filling + 2 m was often exceeded lately. In order to preclude a disaster the excessive wastes accumulated in the lake will be processes at the plant. |
| 28 | I. Valeev, E. Pavlova, A.

| 29 | I. Valeev, E. Pavlova, A. Ghebanov, A. Sedenkov | Field Hydrochemical Studies of Bittern Composition of Western Sivash and its Approximation on Salt Mass to Azov Sea WatersThe main raw material of Crimean Soda Plant Company is salt brine from the Sivash (Eastern, Central and West). Lately in the bittern of Sivash (Western section) Mg+2 and SО-24 ions began accumulating due to recirculation of waste mother liquors and negative effect of drainage from irrigation systems. By 2007 substantial amount of wastes has accumulated in Northern Section of Lake Krasnoye and is still growing. Those are mainly sodium chloride and calcium chloride solutions. There is a disbalance between input to the evaporative accumulator and evaporation from the lake surface. In November 2005-January 2006 and in November 2006-January 2007 Ukrvodgeo Center and NIOCHIM performed field hydrochemical research aimed at desulfatizing of Western Sivash bittern and its salt content nearing that of Azov Sea water.

Formation of new independent components has been established in the system. They are: sodium carbonate in the region with NaCl excess, ammonia carbonate in the region with NH4НСО3 excess. Attempts to obtain final composition of saturated solution failed even during long (more than 5-6 hours) carbonation. Close to the point of triple saturated solution of a quarternary mutual system significant range of ions content values is noted CO32- и HCO-3. This shows that the system is unstable due to increase of balances variability. It is shown that the most complete (systematic) approach to evaluation of carbonation process requires taking into account molecular ratio of crystals forming iones Na+/HCO3- in the final solution composition. It is established that presence of excesses NH4+/Cl- and crystal forming iones Nа+/HCO3- (more than one) in the final solution plays decisiv role in obtaining simultaneous greatest UNa+ и NH. It is shown that with increase of NH4+/Cl- excessive ammonia additionally introduced to soda ash production cycle transforms into ammonia carbonates during carbonation. |

But proposed correlations are built on experimental data on equilibrium pressures over solutions with various ions weights compositions and their application for unbalanced weight systems is not correct. In this work we propose updated data for precarbonation stage dependencies of ammonia and carbon dioxide pressure equilibriums expressed through ions equilibrium in liquid, together with their interaction. |
