克石化使用新型密封采樣設備

中國石油網消息 (記者宋鵬 通訊員楊玲)“這種新安裝的密閉式采樣設備既便于操作,又避免了操作人員取樣時與有毒有害介質直接接觸。”9月4日,正在年60萬噸連續重整裝置取樣的克拉瑪依石化公司煉油第四聯合車間員工努爾艾再孜說。

  據了解,這種采樣器的使用范圍非常廣,油、氣、污水等介質流程的終端都可適用安裝。負責安裝采樣器的技術人員王陽介紹,適用于液體采樣的采樣設備是一種雙閥門閥組結構,不需要采樣時,樣品回流入工藝管道中形成回路,保證所取油樣隨時“新鮮”。更重要的是,這種密封采樣設備避免了作業人員在取樣過程中與有毒介質的直接接觸。氣體介質則采用鋼瓶密閉采樣設備,非常環保。

  “以往,操作員工站在老式的開放式取樣設備前取樣時,要先戴好防毒面罩,有時取含苯、硫化氫等氣體樣時,還須佩戴好空氣呼吸器。”王陽說。

  現在,這種密閉采樣設備都配有特定的采樣瓶,操作工只需要將安有密封橡膠皮瓶口的一端插入取樣針口處,輕輕扳動取樣閥門,便可完成一個油樣的采集,操作非常便捷。

  8個油品樣,努爾艾再孜僅用了六七分鐘就采集完成。而以往,完成這樣的取樣至少得20分鐘。

  “過去放殘樣時,如果發生取樣閥關閉不嚴的情況,還容易造成油品的跑、冒、滴、漏。冬天取樣,管內介質還易發生凍凝。”努爾艾再孜說。

  這種密封采樣設備由于采樣器內油品介質的循環流動,不會出現管內油樣介質冬季凍凝的現象。

  目前,克石化已在年60萬噸連續重整、年100萬噸延遲焦化及年120萬噸柴油加氫改質三套新建裝置使用這樣的采樣設備。下一步,克石化將陸續安裝這種密閉采樣設備。
