The process plant economic evaluation was based on the Chemical engineering plant cost index (CEPCI). It was also applied in the methodology of capital cost estimation to determine the chemical plant construction cost (Lozowski et al. 2012; Yeo et al. 2018). However, the purchase cost calculated by the Lang factor is a rough …

The high cost of biodiesel also hinders its commercialization. In advanced economies, biodiesel costs 1.5–3 times as much as fossil diesel. Biodiesel production is expected to increase in the next few years because of its potential advantages for energy supplies, farm expansion, the economy, and reducing pollution.

Biodiesel, which is considered as a possible substitute of conventional diesel fuel is commonly, composed of fatty acid methyl esters that can be prepared from triglycerides in vegetable oils by transesterification with methanol. The resulting biodiesel is quite similar to conventional diesel fuel in its main characteristics. 2.

Conventionally acid (HCl or H 2 SO 4) or alkali (NaOH or KOH) is used for transesterification of triglycerides. Alkali catalyzed methods have been commercialized and many countries are producing biodiesel using this method. The schematic representation of chemical catalyzed biodiesel production is depicted in Fig. 7.2.

Experimental design was used to study the influence of process variables on ethyl ester conversion. The biodiesel was made using bioethanol and sodium hydroxide as the catalyst on a laboratory scale. The best ethyl ester (biodiesel) conversion was 99.84 wt % after 6 minutes of reaction, obtained with the RD system with plates.
