With application of these coefficients and criteria, modified complexes for the energy separation efficiency of packed-type gas separators aimed to remove liquid aerosols are obtained. Technical characteristics of structured and random packings are given and calculations of energy complexes and of the power required for supplying gas to the purification are made. It is determined that the spiral-prismatic packing is most efficient among all considered random packings and the spiral wound packing RGN-5 (manufactured by LLC EPC “Inzhekhim”) is most efficient among all considered structured packings.","PeriodicalId":33495,"journal":{"name":"Izvestiia vysshikh uchebnykh zavedenii Problemy energetiki","volume":"70 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74629052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is proved that in case of determination of losses of the electric power in lines of shop networks it is necessary to consider influence of the following parameters of the equipment: the heating of conductors caused by passing of current of loading through conductors and ambient temperature; resistance of contact joints of switching devices and their number; type of the load graph; ambient temperatures. The diagram of a shop network and daily load graphs of customers of one of the enterprises is researched.
