PPH吸收塔的措（cuò）施（shī）步驟：

（1）依據規劃任務和工藝要求，確認規劃方案；

（2）針對物係及（jí）分離要求，選擇適宜填料；

（3）確認塔徑、填料（liào）層高度等工藝尺度（考慮噴淋密度）；

（4）核算塔高、及填料層的（de）壓降；

預防措施

（1）科學選材，在低溫下嚴格禁止選用非低溫用鋼，選（xuǎn）擇高抗蝕（shí）的資料。

（2）改良結構規劃，結構（gòu）的（de）規劃（huá）過程中（zhōng），盡量選用（yòng）油滑過度以削減構件的應力會（huì）集；設備運行過程中，應盡或許地避免頻頻的交變載（zǎi）荷，避免（miǎn）超溫運作及局部過熱，防止出現水停滯，經過（guò）熱處理對殘餘應力有效消除。

（3）強化（huà）原料（liào）性能的定期檢驗，對金（jīn）屬構件或設備（bèi）所處的環境的腐（fǔ）蝕劑濃度實行嚴格檢測，並（bìng）降低環境介質的有效溫度等。

（4）改（gǎi）善介質環境，削減氧化陽離（lí）子，將恰當元素增加至資猜中，提升資料的抗蝕能力，選用表（biǎo）麵防（fáng）護方法。

以上關於PPH吸（xī）收塔所作的介紹，希望可以幫（bāng）到您。

PPH absorption tower steps:

(1) Confirm the planning scheme according to the planning task and process requirements;

(2) According to the requirements of the system and separation, choose the appropriate filler;

(3) confirm the size of the tower, the height of the packing layer and other technological scales (considering the spray density);

(4) check tower height and pressure drop of packing layer;

preventive measure

(1) Scientific material selection, strictly prohibit the selection of non-low-temperature steel at low temperature, choose high corrosion resistance data.

(2) To improve the structural planning, in the process of structural planning, try to choose excessive oil slip to reduce the stress aggregation of members; In the process of equipment operation, frequent alternating load, overtemperature operation and local overheating should be avoided as far as possible, and water stagnation should be prevented. After heat treatment, residual stress can be effectively eliminated.

(3) To strengthen the regular inspection of raw material properties, to metal components or equipment in the environment of the corrosive concentration of the implementation of strict detection, and reduce the effective temperature of the environment medium.

(4) Improve the medium environment, reduce the oxidation cation, increase the appropriate elements to the information guessing, improve the corrosion resistance of the data, choose the surface protection method.

The above introduction of PPH absorber, I hope to help you.
