從腐蝕介質(zhì)分析及實際腐蝕情況判斷，吸收穩(wěn)定系統(tǒng)腐蝕基本上屬于H：S一HZO型低溫腐蝕，換熱器腐蝕形態(tài)表現(xiàn)為碳鋼均勻減薄、氫鼓泡和硫化物應(yīng)力腐蝕開裂。在有水存在的條件下，HZS溶于水中形成酸性腐蝕介質(zhì)，其主要反應(yīng)為：Fe H25一FeS H：

From the analysis of corrosive medium, corrosion case judgment, absorption and stabilization system corrosion essentially belongs to the low temperature corrosion of H2S HZO, morphological erosion performance as a homogeneous carbon steel cut thin, bubbling hydrogen sulfide and should stress corrosion cracking. In the presence of water, HZS soluble in water to form an acid corrosion medium, the main reaction is: H25 FeS a H Fe:

　?。?）采用氣壓機(jī)出口富氣水洗或堿洗的方法可以有效地脫除其中的H乃，從而降低腐蝕介質(zhì)濃度，減輕設(shè)備腐蝕程度。另外在設(shè)備制造及安裝過程中應(yīng)注意降低應(yīng)力水平，塔體應(yīng)進(jìn)行整體熱處理，塔內(nèi)構(gòu)件選用18一8等不銹鋼材質(zhì)。

(1) the is effective to remove the H from the air pressure machine, which can effectively remove the concentration of the corrosive medium, and reduce the corrosion degree of the equipment. Also in the equipment manufacturing and installation process should pay attention to reduce the stress level, the tower body should carry on the whole heat treatment, tower internals selection 18 8 stainless steel material.

　　（2）為了徹底消除硫化鐵自燃帶來的安全危害，我們在2000年大修停工期間在吸收穩(wěn)定系統(tǒng)試用了硫化鐵鈍化劑，能夠有效清除設(shè)備上積結(jié)的FeS等無機(jī)垢，并且在設(shè)備內(nèi)不產(chǎn)生沉積，不產(chǎn)生廢氣、廢渣，排放物符合環(huán)保要求。使用后塔器內(nèi)壁及換熱器管束表面基本沒有FeS沉積物，設(shè)備內(nèi)異味也明顯減輕，效果顯著。

(2) in order to eliminate caused by spontaneous combustion of iron sulfide safety hazards, we in 2000 overhaul during the period of suspension in absorption and stabilization system trial of iron sulfide passivation agent can effectively remove the equipment on the product structure of the FESinorganic, and produces no deposition in the equipment, does not produce waste gas, waste residue and emissions meet environmental protection requirements. The inner wall of the tower and the heat exchanger www.hreqi.com   tube bundle have noFeSsediment, and the peculiar smell in the device is obviously reduced, and the effect is obvious.

　　環(huán)保效益（1）油氣回收投用后，油氣不再排放到大氣中，有利于改善大氣的質(zhì)量。（2）有利于企業(yè)推行清潔生產(chǎn)，保護(hù)職工的身體健康。（3）實現(xiàn)對主要環(huán)境因素進(jìn)行控制，達(dá)到1501400環(huán)境保護(hù)體系的要求，使裝油臺逐步實現(xiàn)健康、安全、環(huán)境一體化。

Environmental benefits (1) after the oil and gas recovery, oil and gas is no longer discharged into the atmosphere, it is conducive to improving the quality of the atmosphere. (2) is conducive to the implementation of cleaner production, to protect the health of workers. (3) to control the main environmental factors, to achieve the requirements of the 1501400 environmental protection system, so that the oil stage to achieve the gradual implementation of health, safety, environmental integration.
