Abstract:Zaradi povečanja porabe organskih topil v proizvodnih obratih smo se odločili za širitev cisternskega skladišča. Povečali smo ga za štiri rezervoarje in omogočili distribucijo topil preko cevnega mostu v oddelke. V diplomskem delu je prikazana natančna izbira črpalk in meritev, s pomočjo katerih smo določili ustrezen pretok. Za prečrpavanje iz avtomobilskih cistern v rezervoarje, za transport topil v obrate in za transport topil v polnilnico kontejnerjev so bile izbrane centrifugalne črpalke, izdelane iz nerjavnega jekla, kakovosti AISI 316 L. Prav tako so bile iz enakega materiala izbrane pnevmatske črpalke, ki se uporabljajo za prečrpavanje topil iz kontejnerjev ali odpadnih topil iz kontejnerjev v cisterno za odvoz. Tudi merilniki pretoka so bili izbrani iz omenjenega materiala. Izbrano nerjavno jeklo vsebuje elemente, ki najbolj ustrezajo našim potrebam, in sicer je njegova maksimalna vsebnost ogljika 0,08 %, maksimalna vsebnost mangana 2 %, vsebnost kroma 17 %, niklja 12 % in vsebnost molibdena 2,5 %. Takšna kemijska sestava materiala predstavlja veliko odpornost proti koroziji, eksplozijsko varnost, toplotno odpornost in biološko nevtralnost. Vplivom korozije pa smo se izognili tudi s stalno zalitostjo črpalk s črpanim medijem. Ob ugotovitvah neustreznega pretoka za distribucijo topil v obrate smo se odločili za uporabo zaslonke z namenom zmanjševanja dozirnega tlaka in posledično tudi zmanjšanja pretoka. Izvedeni so bili preizkusi doziranja ob uporabi različnih zaslonk, ki so nas privedli do izbire in vgradnje 18 mm zaslonk v obratih in 19 mm zaslonk na sistemih v skladišču tekočih surovin.

Title:DISTRIBUTION OF ORGANIC SOLVENTS
Abstract:Because of the increase in the consumption of organic solvents in the manufacturing plants, we decided to expand the storage cistern. We have enlarged it by four reservoirs and enabled the distribution of solvents over the tubular bridge to the sections. The thesis shows the precise choice of pumps and measurements by which we determined the appropriate flow. For the pumping from the car tanks, for the transport of solvents to the plants and the transport of solvents in the filling centre of containers centrifugal pumps made of stainless steel quality AISI 316 L have been selected. Of the same material have been also selected pneumatic pumps, serving for pumping solvents out of containers or solvent waste out of containers into the tank for removal. Flow meters were selected from the same material as well. The latter consists of elements that best suit our needs, namely, its maximum carbon content is 0.08 %, maximum content of manganese is 2 %, chromium content is 17 %, there is 12 % of nickel and 2.5 % of molybdenum. Chemical structure like this presents high resistance against corrosion, explosion security, thermal resistance and biological neutrality. We have avoided the influence of corrosion with permanent filling up of the pumps by the pump media. Because of the findings of inadequate flow distribution of solvents to the plants, we decided to use the aperture in order to reduce the dosing pressure and consequently reduce the flow. Feeding experiments using different apertures were carried out, which have led us to the selection and installation of 18 mm apertures in the plants and 19 mm apertures in the systems of STS.
Keywords:distribution, organic solvents, pumps, pipelines, flow meters, reservoirs, anti-explosion protection.
