Analysis of Blockage in Heat-Exchanger of Crude Oil Stabilizer Station

Abstract:

The most shortage of heat-exchanger in crude oil stabilizer station was scaling. The forming of blockage has been confirmed, by the methods of chemical analysis, XRD diffraction and scanning electron microscopy (SEM) to analyse the qualitative and quantitative of it. The blockage is due to the impurity in oil. On one hand, the inorganic substances, mainly Si⁴⁺ and Al³⁺, adhere to the wall by chemical reaction. On the other hand, heavy oil, like asphaltenes, is eluted from flow and exacerbated the adsorption force. Thus, a group of organic and inorganic clogs has formed, which cause the scaling of heat-exchanger unit.
