Introduction 3 eia.gov

Motivation 4 Advantage of the arbitrage in energy markets Improved process efficiency of 80% by combining concurrent modern technologies as compared to 16%. A feedstock of natural gas results in a sulfur and aromatic-free fuel, which is more environmentally and consumer friendly than fuels derived from crude oil. Derived transportation fuels have excellent cold flow properties, high cetane rating and high octane rating. Clean and powerful fuels for the future

5 Product Striking Characteristic Use LPG No CO emissions Fork lift trucks, indoor vehicles. Naphtha High octane rating Alternative and Premium blend stock for conventional gasoline Jet fuel Excellent cold flow properties Alternative and premium blend stock for jet fuel DieselCetane rating of 72 Alternative and premium blend stock for conventional diesel

Integrated Shale Gas Complex 9

The Fischer-Tropsch Refinery is one of nine plants of an integrated shell gas complex. The Fischer-Tropsch Refinery is receiving the Syngas from the Syngas plant, Electricity, Steam and Boiler Feed Water from the CHP plant at no cost. The purge is being sent out to the CHP plant to produce electricity and steam. The aqueous stream is being sent to the Water Treatment plant. 10 Integrated Shale Gas Complex

11 Expected simple payback period is 4.24 years. Prices of natural gas are expected to decrease further, which will cause the payback period to decrease significantly.

Summary 16

Environmental Analysis 17 High Cetane rating causes the thermodynamic efficiency of the diesel engine to improve, which reduces CO 2 and CO emissions in the atmosphere. Due to the absence of aromatics in the process, the resultant LPG, Diesel, Jet, and Naphtha are very clean. Absolutely no soot formation occurs in the engines, which further reduces the CO 2 and CO emissions in the environment. Due to the absence of sulfur, there are no SO x emissions and no sulphuric acid droplets in the Tropopause. Therefore, no acid-gas mist formation occurs. Droplet and SO x accumulation in the Tropopause causes global cooling, thus interfering with the global climate.

Recommendations Installing a DWC will reduce the equipment cost significantly and improve process efficiency. It is recommended to go ahead with this project to stage gate 2 as it is a money maker and is environmental friendly. 18

Summary The process starts with 250,000 lb/hr of fresh Syngas is used as the feed stock with a ratio of 2.05:1 of H2 to CO It takes 4.24 years for pay back NPV 745 Million Dollars – 20 years 19
