Abstract
Hydrogenated renewable diesel (HRD), which is defined as paraffinic hydrocarbon derived from vegetable oil and animal fat, has received consideration worldwide as an alternative diesel fuel. In this work, HRD production from palm fatty acid distillate (PFAD) feedstock was designed and techno-economic evaluation of a heat-integrated HRD production plant was performed. HRD production for a PFAD feed flow rate of 579 g s−1 was simulated in Aspen Plus® software as the base-case model; the minimum energy consumption was calculated using pinch point analysis, and a heat exchanger network of heat integration was designed. Subsequently, the modified heat integration HRD production plant was subjected to economic analysis to determine the HRD production attractiveness to investment. It was found that investment in HRD production would be attractive as the fixed capital investment cost of the production plant was 20.735 M$. With a HRD selling price of 950 $ m−3 the project gave 39.4% of return on investment and 3.0 years of payback period. If the company has PFAD readily available, a HRD production project was attractive to investment with a NPV of 61.89 M$.
