換熱器腐蝕的防范

安全效益油氣如果不被回收,這種氣體擴散在裝油臺區域,再與空氣混合,很易形成爆炸氣體,由于油氣量較大對裝油作業安全極為不利,一不小心易引起燃燒爆炸。回收后使裝油臺消除了安全生產中一個極重要的隱患因素。生產操作改造后的油氣回收流程較短,換熱器工藝條件易操作,操作工每班2個人就可以保證裝置正常運行。

Safety benefit of oil and gas if not be recovered and the gas diffusion in oil and Taiwanarea, and then mixed with the air, is easy to form gas explosion, due to oil and gas production is larger is extremely detrimental to safe operation of oil, one not careful easy to cause combustion and explosion. After the recovery of the oil table to eliminate the safe production of a very important risk factors. Production operation after the transformation of oil and gas recovery process shorter, process conditions and easy operation operator 2 people in each class can ensure the normal operation of the device.

通過對富氣的安全性、裝置的處理量、工藝設備熱量平衡模擬計算等方面的分析論證,利用現有設備改用柴油吸收油氣的改造方案是可行的。為了進一步改善換熱器裝置的性能,建議:

It is feasible to use the existing equipment to use diesel oil to absorb oil www.hreqi.com   and gas by analyzing and demonstrating the safety of the gas, the processing capacity of the device, the calculation of the heat balance of the process equipment and so on. In order to further improve the performance of the device, the proposed:

(1)同時啟動2臺貧油泵增加吸收劑量,把柴油人塔溫度降低到最低,假定為32℃,通過模擬計算回收量可增加20Okg/h。但循環水量需要提到3ot/h,二級換熱器的面積需增加30一4OmZ。

(1) at the same time to start the 2 pumps to increase the absorption dose, the diesel tower temperature to a minimum, assuming a 32 c, calculated by the analog recovery can be increased by 20Okg/h。 However, the circulating water needs to be mentioned in 3ot/h, the area of the two stage heat exchanger needs to be increased by 30 4OmZ。

(2)提高羅茨風機的壓力增加塔內吸收壓力,從而提高吸收率。

(2) improve the blower pressure increase in absorption tower pressure, so as to improve the absorption rate.

(3)用水作為噴射器的流體力,可節約柴油循環量,通過改造提高液分離罐的分離能力,使水與柴油分離徹底。

(3) the use of water as a jet of fluid force, can save diesel cycle, through the transformation to improve the separation capacity of the liquid separation tank, so that the separation of water and diesel completely.

(4)設法降低柴油的吸收溫度,從而提高吸收塔的效率。

 (4) to try to reduce the absorption temperature of diesel fuel, so as to improve the efficiency of the absorption tower.
