Abstract
Fischer Tropsch is a polymerization reaction that produces a long hydrocarbon chain such as linear paraffin and linear olefins along with water that contains oxygenates. Water is the by-product in Fischer Tropsch synthesis in which it does contain impurities such as olefins and oxygen-containing components. Therefore, this research aims to study the Fischer Tropsch water composition and its effects on the produced wastewater chemical oxygen demand (COD) by using Aspen simulation. Correspondingly, this study designs a Fischer Tropsch water distillation unit that can recover 1.2% volatile organic compounds from the wastewater. This research has identified three (3) sections in the Fischer Tropsch water distillation unit which are distillation, recovery, and neutralization. A steady-state model simulation is conducted through Aspen simulation with UNIQUAC-HOC as the thermodynamic model. The developed simulation model found to be less than 10% deviation as compared to the actual data from the natural gas processing plant located in Bintulu. The research finds that the variation of alcohol, aldehyde, and ketone does not affect the COD of the wastewater. However, small changes in carboxylic composition in the wastewater could cause high COD in wastewater. Meanwhile, the COD statistical model has been developed with a residual error of less than 2%. The model can be used to predict the wastewater COD based on the Fischer Tropsch water composition. Overall, the developed water distillation unit can treat up to 2,100 tonnes of Fischer Tropsch water per day with 97% COD removal efficiency.
