Recovery of Heat Energy at Cryogenic Level with Circulating Reflux Unit on Top of Atmospheric Tower 常压塔顶循环回流回收低温位热能
Analysis on Corrosion of overhead circulating reflux pump for catalytic fractionating tower 催化分馏塔顶循环回流泵腐蚀原因分析
Accompanying with the salt deposition, there were inflexible adjustment of fractionator top temperatures, cavitation in top circulating reflux pump, production of light gas oil with substandard flash point as well as difficult drawing out from the column, etc. 结盐时伴随有塔顶温度调整不灵活,塔顶循环回流泵抽空和轻柴油闪点不合格和抽出困难等现象。
