Technical and economic efficiency of processing acidic wastewater from the oil and fat industry into necessary agricultural products

Abstract

In this artist the economic efficiency of organizing the production of crude fatty acids in the fat and oil industry of Uzbekistan is presented. Cotton soapstock is a difficult-to-saponifiable oily substance, which requires a long time for its saponification. Therefore, to intensify it, it is proposed to saponify the soap stock using the ultrasonic method. The resulting crude fatty acids after the new approach led to a reduction in the cost of the product. The second problem of enterprises is the formation of acidic wastewater, which, after neutralization with an expensive reagent sodium carbonate, is discharged into the city sewerage system. Therefore, it is proposed to neutralize wastewater with carbonate phosphorite of the Central Kyzylkum. As a result, after processing the wastewater, phosphorus fertilizer was obtained. Technical and economic calculations showed that the cost of phosphorus fertilizer is only 616,978 sums or 50 US dollars per ton. Thus, in oil and fat industry enterprises it is possible to organize the production of fertilizers, a product with an additional amount.
