河南油田采油一廠K6-18井于2016年1月8日下入CASN亞穩特種合金防垢裝置,2017年2月16日檢泵作業,下圖為安裝防垢裝置前后的情況對比
下入裝置前抽油桿接箍腐蝕,抽油桿結垢約2-3毫米
下入裝置后抽油桿無腐蝕,無結垢

冷卻水系統 | 楚雄鋼鐵大水梁冷卻水管道防垢
● 由于冷卻水管道供水故障,2017年11月安裝CASN防垢裝置。
● 使用一年時間內沒有投入除鹽水, 未加任何藥物。
運轉一直正常運行。
● 冷卻水品質符合國標(重點檢測值,主要通過連排和強排來進行調節) 安裝三個月后從下游管道中清理出約2.5噸脫落的舊垢。
換熱系統 | 吉林油田乾安采油廠聯合站換熱爐防垢
● 吉林油田乾安采油廠聯合站換熱爐結垢非常嚴重,管壁內結垢厚度達20MM,嚴重影響正常生產。
● 在安裝CASN防垢裝置之前,先后使用化學除垢和其它除垢方法,都沒有明顯效果。2018年1月安裝了4套CASN防垢裝置后,12個月后打開檢查,發現原來的管線內不僅沒長新垢,連原來的老垢也只剩下1MM厚。
換熱系統 | 吉林松原石化冷卻系統DN80及DN100變徑式
換熱系統 | 寧夏石化換熱器上的使用情況
● 2018年7月23日換熱器進水口管線上安裝CASN防垢裝置一臺,從施工準備到安裝完畢確認投用,只用了不到3個小時的時間。安裝設備時檢查盤管,結垢情況比較嚴重,盤管外壁附著白色硬質水垢,用金屬工具敲擊、刮擦很難使水垢脫落,后使用尖錘敲擊才使水垢脫落大概2cm2見方,露出管道金屬本體。
● 在正常運行90天后,于2018年10月23日觀察具體使用效果,結果分析如下: 設備使用狀況分析:CASN防垢裝置投用后,由于水箱內的冷卻水經設備處理,盤管外壁的硬垢得到軟化,盤管外壁所結的硬垢得到軟化變得蓬松,使用金屬物刮擦大面積脫落,盤管彎頭焊縫處凝結的水垢也得到有效的軟化。觀察金屬本體無新垢凝結,在水箱下方水流沖刷強度高的地方效果更加明顯。
● 工藝技術分析:由于提高了熱交換效率,安裝90天后,日處理量增加了72噸,達到預期效果。
冷卻水系統 | 赤峰富邦銅礦制氧車間冷卻水真空泵防垢
循環水系統 | 大冶有色選礦循環水系統防垢
● 使用前:大冶有色選礦使用的循環水是未經任何方法進行水處理的地下水,以前設備結垢較為嚴重,影響機組效率,需定期通過酸洗進行除垢,甚至還要更換排水管。
● 使用后:從2019年1月9日在總入水口安裝了CASN防垢裝置后,使用情況良好。從六臺機組的三個觀測點所反映出的情況,達到明顯的防垢除垢的使用效果。
冷卻水系統 | 浙江傳化集團液壓油冷卻水系統
冷卻水系統 | 廣西天桂鋁業循環冷卻水系統DN300
廣西天桂鋁業氫氧化鋁母液板式換熱器冷卻水,日處理量5000m3,原清理方法酸洗,后改為高壓清洗,清理周期2次/年,安裝之后清理周期1次/2年。
玉門油田安裝現場
未安裝裝置之前井情況:每口油井平均洗井6次/年。
已安裝50口井情況:截止目前從油井生產功圖顯示,油井生產形勢平穩運行,載荷穩定,該防蠟防垢工藝達到了理想的效果,在沒有實施任何另外的清防蠟、清防垢措施的情況下,減緩了結蠟,結垢速度,生產周期和油井洗井周期得到了明顯的延長,截止2020年12月31日,共計有12口井未洗井,2口井洗了1次井,14囗井洗了2次井,8口井洗了3次井,9口井洗了4次井,4口井洗了5次井,1口井洗了6次井,平均每口井洗井2次/年。
集輸系統 | 玉門油田酒東聯合站換熱器系統
在酒東聯合站試驗應用亞穩合金防垢緩蝕裝置取得實效,應用期間內加執爐進出口壓損穩定在0.02MPa,盤管結垢速率降低80%以上,效果顯著。
酒東地層產出液呈現高礦化度、高鈣鎂離子濃度的特點。在長期生產運行過程中,高含水原油經加熱爐加熱,導致盤管結垢嚴重通常使用兩年便需停運系統。
安裝亞穩合金防垢緩蝕裝置后,通過進出口掛片稱重發現,加熱爐出口掛片腐蝕速率在0.021mm/a為輕度腐蝕。且該裝置使用過程中無需停運維護,大幅節省了人力物力。下步,將繼續跟蹤該裝置的長期使用效果,更深層次評價裝置的實用性。
