<div>　　在煤化工領域，低溫甲醇洗工藝具有舉足輕重的地位。無論是煤的直接液化、間接液化，還是煤氣化制取化工產品的工藝裝置中，大多要有氣體凈化工藝，而低溫甲醇洗工藝無疑是目前最具競爭實力、成熟的氣體凈化技術，已被廣泛應用于國內外合成氨、合成甲醇和其他羰基合成、城市煤氣、工業制氫和天然氣脫硫等氣體凈化裝置中。尤其是對煤（水煤漿）或渣（重）油為原料制取合成氣的凈化，采用此方法則效果更佳。在國內，以煤、渣油為原料建成的大型合成氨、合成甲醇裝置中也大都采用這一技術。低溫甲醇洗工藝投資較高，但與其它脫硫、脫碳工藝相比具有電耗低、蒸汽消耗低，溶劑價格便宜，操作費用低等優點。特別是脫硫的凈化度高，對甲醇及合成氨生產十分有利。 </div> <div><span style="font-family:times new roman,times,serif;"> 低溫甲醇洗工藝中，硫化氫沒有發生化學轉化，而是被富集到酸性氣體中，然后采用克勞斯工藝對酸性氣體中的硫化氫進行處理。但克勞斯脫硫流程是一種針對高硫含量酸性氣的催化氧化流程，投資高，流程長，對硫含量要求在10%以上，不適合低入口硫含量、高凈化度酸性氣體脫硫。對于有高凈化度要求的酸性氣體脫硫，需要多級克勞斯才能完成，流程長，投資高，在H2S>12%的硫含量時,氣體的腐蝕性增強，毒性大，且易燃易爆，NHD或低溫甲醇洗裝置中H2S需要反復吸收解析濃縮，最終勉強達到12%以上，勉強適合用克勞斯硫磺回收技術，且克勞斯硫磺回收脫硫后的尾氣中H2S或SO2很難達到國家排放標準，常見的含量300~3000ppm，經常需要進一步處理，克勞斯硫磺回收技術顯然不是理想的酸性氣脫硫技術。 </span></div> <div><span style="font-family:times new roman,times,serif;"> 煙臺新瑞環?？萍加邢薰咀?013年5月成立以來，一直致力于硫化氫脫除工藝、硫化氫脫硫系列藥劑的開發、研發工作。截止目前我公司開發的BLUER-PRO濕法螯合鐵脫硫工藝、XR-SR系列脫硫藥劑已在國內外20余套硫磺回收裝置應用，脫硫效果顯著，凈化后混合氣體中H2S含量≤5ppm，與北京化工大學、陜西超重力研究中心、青島科技大學等多所高校、科研院所建立了長期的合作，持續對現有硫化氫脫除工藝、脫硫系列藥劑進行優化。</span></div> <div> <div><span style="font-family:times new roman,times,serif;">BLUER-PRO工藝具有傳統液相氧化催化法的所有優點，具體如下：</span></div> <div><span style="font-family:times new roman,times,serif;">（1）硫化氫脫除率高，一步反應的脫除率達到99.99%以上，處理過的尾氣H2S濃度在可以控制在5ppm以下。</span></div> <div><span style="font-family:times new roman,times,serif;">（2）應用范圍廣，可以處理各種含H2S氣體，選擇性高?！　?/span></div> <div><span style="font-family:times new roman,times,serif;">（3）操作彈性大，能夠適應原料氣中H2S濃度、原料氣流量從0～100%的大幅度波動變化?！　?/span></div> <div><span style="font-family:times new roman,times,serif;">（4）環境友好，沒有三廢產生?！　?/span></div> <div><span style="font-family:times new roman,times,serif;">（5）反應條件溫和，為液相、常溫常壓反應過程?！?/span></div> <div><span style="font-family:times new roman,times,serif;">（6）工藝簡單，開、停工及日常操作均簡單?！?/span></div> <div><span style="font-family:times new roman,times,serif;">（7）經濟性能高，占地面積小，投資費用少，日常運行成本低?！　?/span></div> <div><span style="font-family:times new roman,times,serif;">（8）安全性能高，系統不使用任何有毒的化學物質，硫磺產品中沒有H2S氣體?！　?/span></div> <div><span style="font-family:times new roman,times,serif;">（9）運行可靠，獨特的設計能夠保證無堵塞現象發生，保證長周期穩定運行。</span></div> <div><span style="font-family:times new roman,times,serif;">（10）硫磺品質好，雜質少。</span></div> <div><span style="font-family:times new roman,times,serif;"> 本裝置適應的H2S含量最低0最高100%，且H2S轉化一步即可完成。能耗低，沒有三廢產生。與傳統克勞斯脫硫相比，投資可節省50%，運行費用可節省50%。我們開發的螯合鐵濕法脫除煤氣中硫化氫生產項目，工藝先進，硫化氫脫除效率高，凈化后煤氣中H2S含量低于5ppm，響應國家節能減排的號召，符合清潔生產的工藝流程，爭取為國家的環保事業發展做出更大的貢獻！</span></div> </div>
