PPH吸收塔的措施步骤:

(1)依据规划任务和工艺要求,确认规划方案;

(2)针对物系及分离要求,选择适宜填料;

(3)确认塔径、填料层高度等工艺尺度(考虑喷淋密度);

(4)核算塔高、及填料层的压降;

预防措施

(1)科学选材,在低温下严格禁止选用非低温用钢,选择高抗蚀的资料。

(2)改良结构规划,结构的规划过程中,尽量选用油滑过度以削减构件的应力会集;设备运行过程中,应尽或许地避免频频的交变载荷,避免超温运作及局部过热,防止出现水停滞,经过热处理对残余应力有效消除。

(3)强化原料性能的定期检验,对金属构件或设备所处的环境的腐蚀剂浓度实行严格检测,并降低环境介质的有效温度等。

(4)改善介质环境,削减氧化阳离子,将恰当元素增加至资猜中,提升资料的抗蚀能力,选用表面防护方法。

以上关于PPH吸收塔所作的介绍,希望可以帮到您。

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.
