Description
Przedmiotem wynalazku jest sposób oraz urzadzenie do katalitycznej konwersji tlenku wegla z para wodna w gazie weglowym przy produkcji gazu miejskiego z weglowodorów, majace zastosowanie w przemysle gazowniczym.The subject of the invention is a method and a device for the catalytic conversion of carbon monoxide into steam in coal gas in the production of municipal gas from hydrocarbons, applicable in industry gas.
W dotychczas stosowanych sposobach przy produkcji gazu miejskiego z weglowodorów na ogól wystepuje czlon katalitycznej konwersji tlenku wegla z para wodna, wskutek czego wytworzony gaz jest nietoksyczny i wykazuje duza zawartosc wodoru, natomiast gazy weglowe nie byly dotychczas poddawane katalitycznej konwersji tlenku wegla z para wodna, próbowano jedynie uzyskac ich detoksykacje na drodze chemicznego wymycia tlenku wegla.In the methods used so far in the production of city gas from hydrocarbons, it is generally present member of the catalytic conversion of carbon monoxide from water vapor, as a result of which the gas produced is non-toxic and has a high hydrogen content, while carbon gases have not been catalytically processed so far the conversion of carbon monoxide into water vapor, attempts were only made to detoxify them by chemical means carbon monoxide washing.
W dotychczas stosowanych urzadzeniach za dowolnego typu reaktorem rozkladczym weglowodorów umieszczono reaktor katalitycznej konwersji tlenku wegla z para wodna a za nim wymiennik ciepla.In the devices used so far, there is any type of hydrocarbon decomposition reactor there is a catalytic converter for the conversion of carbon monoxide into steam, followed by a heat exchanger.
Sposób katalitycznej konwersji tlenku wegla z para wodna w gazie weglowym przy produkcji gazu miejskiego z weglowodorów wedlug wynalazku polega na tym, ze przez rozprezanie w strumiennicy od cisnienia co najmniej 1,5 atn technologicznej pary wodnej zasysa sie gaz weglowy podgrzewany w wymienniku ciepla przez gaz wylotowy z reaktora konwersji, a nastepnie laczy w mieszalniku z gazem z pólspalania weglowodorów i poddaje w znany sposób katalitycznej konwersji w reaktorze.A method of catalytic conversion of carbon monoxide from water vapor in coal gas in gas production according to the invention, consists in the fact that by expanding in the ejector from pressure at least 1.5 atm of technological steam, coal gas heated in the heat exchanger is sucked in through the off-gas from the conversion reactor and then combines in a mixer with the gas from the semi-combustion of hydrocarbons and subjected to catalytic conversion in a reactor in a known manner.
Istota urzadzenia wedlug wynalazku skladajacego sie z czlonu konwersji tlenku wegla zlozonego z reaktora zawierajacego katalizator oraz wymiennika ciepla z przewodem doprowadzajacym gaz weglowy polega na tym, ze przed czlonem konwersji znajduje sie mieszalnik wyposazony w natrysk wodny i zawór spustowy, a do mieszalnika wbudowana jest strumienica parowo-gazowa oraz przewód doprowadzajacy gaz z reaktora rozkladczego weglowodorów przy czym strumienica zawiera przewód doprowadzajacy pare technologiczna oraz przewód doprowadzajacy gaz weglowy.The essence of the device according to the invention, consisting of a carbon monoxide conversion unit the reactor containing the catalyst and the heat exchanger with the supply line for coal gas consists the fact that in front of the conversion unit there is a mixer equipped with a water spray and a drain valve, and the mixer has a built-in steam-gas ejector and a gas supply pipe from the reactor decomposing hydrocarbons, the ejector having a conduit for the process steam and Coal gas supply line.
Urzadzenie wedlug wynalazku przedstawione na rysunku posiada mieszalnik 1, reaktor konwersji tlenku wegla 2 oraz wymiennik ciepla 3. Gaz z pólspalania weglowodorów doplywa przewodem 4 w temperaturze2 100 718 zazwyczaj 700-850°C pod cisnieniem okolo 400—600 mm H2 0* Strumienica 5 zasilana para technologiczna doprowadzona przewodem 6 pod cisnieniem co najmniej 1,5 atn zasysa z przewodu 11 oczyszczony gaz weglowy, który wczesniej doprowadzono przewodem 7 do wymiennika 3, w którym podgrzewa sie do temperatury 250-350°C i wraz z para wodna doplywa poprzez strumienice 5 do mieszalnika 1. Wytworzona mieszanka gazu z pólspalania weglowodorów gazu weglowego oraz pary technologicznej powinna osiagnac temperature najlepiej 350—450°C.The device according to the invention shown in the drawing has a mixer 1, an oxide conversion reactor coal 2 and a heat exchanger 3. The gas from the half-combustion of hydrocarbons flows through line 4 at a temperature of 2 100 718 typically 700-850 ° C under pressure approx. 400-600 mm H2 0 * Ejector 5 fed with process steam supplied through the line 6 under a pressure of at least 1.5 atm, it sucks purified gas from the line 11 coal, which was previously led through the line 7 to the exchanger 3, where it is heated to temperature 250-350 ° C and together with the steam flows through the nozzles 5 to the mixer 1. Produced the mixture of gas from the semi-combustion of hydrocarbons, coal gas and process steam should reach temperature preferably 350-450 ° C.
W przypadku wyzszej temperatury stosuje sie dodatkowo natrysk wodny 8, przy czym ewentualny odciek wody wpuszcza sie okresowo przez zawór 9. W reaktorze 2, na katalizatorze 10, najlepiej zelazowo-chromowym w temperaturze najlepiej 350—450°C nastepuje konwersja tlenku wegla z para wodna tak, ze zawartosc jego w gazie opuszczajacym reaktor 2 nie przekracza 3% objetosciowych. Gazy poreakcyjne wychodzace z reaktora 2 w temperaturze 300—400°C ochladzaja sie w wymienniku ciepla 3 do temperatury 100-200°C» po czym sa kierowane do chlodzenia koncowego i wzbogacania.In the case of higher temperatures, a water spray 8 is additionally applied, with possible drainage water is periodically introduced through valve 9. In reactor 2, on catalyst 10, preferably iron-chromium at a temperature of preferably 350-450 ° C, carbon monoxide is converted into water vapor so that its content in the gas leaving the reactor 2 it does not exceed 3% by volume. Post-reaction gases leaving the reactor 2 at a temperature of 300-400 ° C they are cooled in a heat exchanger 3 to a temperature of 100-200 ° C »then they are directed to final cooling and enrichment.
Urzadzenie wedlug wynalazku zostalo w przypadku wykonania przedstawione na rysunku schematycznie.In the case of its implementation, the device according to the invention is shown schematically in the drawing.
