Description

Przedmiotem wynalazku jest sposób rozladunku dwusiarczku wegla z cysterny do zbiornika przy zastosowaniu zamknietego obiegu azotu.Dotychczas znany i stosowany sposób rozladunku cystern z plynnego dwusiarczku wegla polega na uzyciu wody lub azotu jako czynnika roboczego, przy czym woda z uwagi na duze koszty jej oczy¬ szczania jest stopniowo eliminowana i zastepowana azotem. W stosowanym obecnie sposobie przy uzy¬ ciu azotu po opróznieniu cysterny z dwusiarczku wegla pozostaje w niej sprezony azot zmieszany z parami dwusiarczku wegla, iktóry kierowany jest poprzez komin wzglednie komin — pochodnie do atmosfery lub do procesu polegajacego na absorp¬ cji par dwusiarczku wegla w oleju przy czym oczyszczony azot uchodzi do atmosfery.Wedlug wynalazku rozladunek dwusiarczku we¬ gla z cystern do zbiorników przy zastosowaniu zamknietego obiegu azotu ipolega na tym, ze ciekly dwusiarczek wegla znajdujacy sie w cysternie pod wplywem dzialania sprezonego azotu jako czynni¬ ka roboczego zostaje rurociagiem przetlaczany do zbiornika. Równoczesnie w trakcie przetlaczania dwusiarczku wegla do zbiornika, azot znajdujacy sie nad cieklym dwusiarczkiem wegla w tym zbiorniku, zostaje wypychany poprzez rurociag do zbiornika kloszowego uszczelnionego woda. Do tego zbiornika doprowadzany jest równiez osobnym ru- dociagiem swiezy azot, którego ubytek wynika 10 15 20 25 30 2 z koniecznosci pozostawienia pewnej ilosci azotu w cysternie ze wzgledu na technologie ponownego napelniania cystern dwusiarczkiem wegla.Po rozladunku dwusiarczku ..wegla, nastepuje w cysternie redukcja cisnien do l,l-rl,3 Pa umo¬ zliwiajaca powrót azotu z cysterny rurociagiem do zbiornika kloszowego, z którego p i zbiornik cisnieniowy, ponownie sprezony azot do¬ prowadzany jest rurociagiem do nastepnej cysterny celem jej rozladowania z dwusiarczku wegla.Zastosowanie sposobu rozladunku dwusiarczku wegla z cystern do zbiorników przy obiegu zam¬ knietym azotu daje te korzysci, ze przede wszyst¬ kim eliminuje skazenie atmosfery przez calkowite zabezpieczenie przed przedostawaniem sie par dwu¬ siarczku wegla do atmosfery, jak równiez ograni¬ cza zuzycie azotu do ilosci niezbednej do wypel¬ nienia pustych cystern ze wzgledu na technologie ich ponownego napelniania.Wynalazek zostanie wyjasniony na podstawie ry¬ sunku, który przedstawia schemat technologiczny instalacji rozladunku dwusiarczku wegla z cyster¬ ny do zbiornika przy zastosowaniu zamknietego obiegu azotu.Ze zbiornika kloszowego 1 uszczelnionego woda, poprzez sprezarke 2 i zbiornik cisnieniowy 3 do¬ prowadza sie rurociagiem 4 sprezony azot do roz¬ ladowywanej cysterny 5.

A method of unloading tanks made of liquid carbon disulphide, known and used so far, consists in using water or nitrogen as a working medium, with water due to the high costs of cleaning it it is gradually eliminated and replaced with nitrogen. In the currently used method of using nitrogen, after the cistern is emptied from carbon disulphide, compressed nitrogen remains in it, mixed with vapors of carbon disulphide, and which is directed through the chimney or chimney - flares to the atmosphere or to the process consisting in the absorption of carbon disulphide vapors in oil. According to the invention, the unloading of carbon disulphide from tanks to tanks using a closed nitrogen cycle consists in the fact that the liquid carbon disulphide contained in the tank under the influence of compressed nitrogen as a working factor is transferred to a pipeline to tank. At the same time, during the transfer of carbon disulphide to the tank, the nitrogen above the liquid carbon disulphide in the tank is forced through the pipeline to the water-sealed flared tank. This tank is also supplied with a separate pipeline of fresh nitrogen, the loss of which results from the necessity to leave a certain amount of nitrogen in the tanker due to the technology of refilling tanks with carbon disulphide. After unloading of carbon disulphide, it takes place in the tanker reduction of the pressure to 1.1-rl.3 Pa enabling the return of nitrogen from the tanker through a pipeline to the bowl-shaped tank, from which five pressure tank, re-compressed nitrogen is supplied through a pipeline to the next tanker in order to discharge it from carbon disulphide. Carbon disulfide from tanks to tanks in a closed nitrogen cycle has the advantages that it primarily eliminates contamination of the atmosphere by completely preventing carbon disulphide vapors from entering the atmosphere, as well as reducing nitrogen consumption to the amount necessary for filling. ¬ The refilling of empty tanks due to refilling technologies. Invention will be explained on the basis of the drawing, which shows the technological scheme of the installation for unloading carbon disulphide from the tank to the tank using a closed nitrogen cycle. From the glass bowl 1 sealed with water, through the compressor 2 and the pressure tank 3, compressed nitrogen is fed through a pipeline 4 to a discharged tanker 5. The liquid carbon disulfide filling the tank 5 under the influence of compressed nitrogen acting as a working medium, becomes a pipeline 6 transferred to the tank 7, from which, simultaneously, during the transfer of liquid carbon disulfide, the nitrogen in it is pushed through the pipeline 8 to the lampshade tank 1. After unloading the carbon disulphide, the excess nitrogen remaining in the tank 5 is discharged through the pipeline 9 to the lampshade tank 1 to which fresh nitrogen is supplied via a separate line 10. 10 Patent claim A method of unloading carbon disulphide from a tanker into a tank using a closed nitrogen cycle, characterized in that from the bowl tank (1) through the compressor (2) and the pressure tank (3) is fed through a pipeline (4) to the tank (5), compressed nitrogen, which forwards liquid carbon disulfide through the pipeline (6) to the tank (7), at the same time forcing nitrogen from it through the pipeline (8) to the bowl tank (1) to which is discharged from the tank ( 5) pipeline (9) excess nitrogen and pipeline (10) fresh nitrogen ZGK Oddz. 2 Chorzów, residing in 6177/81 - 105 copies Price PLN 45 PL
