1/10/2019, · Decarboxylation can be used to successfully remove NAs from high acidity crude oils. This process depends on the adsorption of NAs on solid catalysts, and the formation of CO 2 and conversion of NAs. Generally, decarboxylation reactions require a temperature above 250 °C, which in turn leads to serious corrosion problems [12] .

What is pH Adjustment and how pH Neutralization System works?

Acids are used to neutralize bases, and vice versa. The pH adjustment process can be performed in either a batch or continuous flow treatment. Depending on the application, the more data that can be gathered on the expected waste flow, temperatures, and waste stream constituents, the better the system will operate. Batch pH Adjustment Systems
