PPH吸收塔的措施步驟：
（1）依據規劃任務和工藝要求，確認規劃方案；
（2）針對物系及分離要求，選擇適宜填料；
（3）確認塔徑、填料層高度等工藝尺度（考慮噴淋密度）；
（4）核算塔高、及填料層的壓降；
預防措施
（1）科學選材，在低溫下嚴格禁止選用非低溫用鋼，選擇高抗蝕的資料。
（2）改良結構規劃，結構的規劃過程中，盡量選用油滑過度以削減構件的應力會集；設備運行過程中，應盡或許地避免頻頻的交變載荷，避免超溫運作及局部過熱，防止出現水停滯，經過熱處理對殘余應力有效消除。
（3）強化原料性能的定期檢驗，對金屬構件或設備所處的環境的腐蝕劑濃度實行嚴格檢測，并降低環境介質的有效溫度等。
（4）改善介質環境，削減氧化陽離子，將恰當元素增加至資猜中，提升資料的抗蝕能力，選用表面防護方法。
以上關于PPH吸收塔所作的介紹，希望可以幫到您。
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.
