Direct Reduction Iron Plant

This document provides a detailed analysis of the Direct Reduction Iron Plant project, including the design basis, block flow diagrams, and overall ASPEN simulation results. Key aspects such as energy sinks and loads, equipment sizing, and transportation costs are meticulously outlined. Questions addressed include the catalyst selection for the primary reformer, oxygen purity requirements, and impurity concerns with iron ore feedstock. The document serves as a comprehensive guide for understanding the complex processes involved in establishing an efficient iron production facility.

  1. Direct Reduction Iron Plant Group Golf Selimos, Blake A. Arrington, Deisy C. Sink, Brandon Ciarlette, Dominic F. (Scribe) Advisor : Orest Romaniuk

  2. Table of Contents Slide 3 – Previous Questions Slide 4 – Design Basis Slide 5 – Block Flow Diagram Slide 6 – Overall ASPEN Simulation Slide 7 – Flow Diagram 1 Slide – Flow Diagram 2 Slide – Flow Diagram 3 Slide – Flow Diagram 4 Slide – Energy Sinks and Loads Slide – Sizing, Cost, and Utilities Slide – Summary, and Work in progress

  3. Previous Questions • What type of catalyst will we be using in the primary reformer? • What is the lowest purity of oxygen the oxygen fuel booster can operate with? • Impurity concerns iron ore feed.

  4. Design Basis • 0.126 mmlbmols/day of natural gas feedstock will be supplied for process from Gas Treatment Plant; natural gas is the main source for Carbon for the reformer • Supply the back-end CO2 to Industrial Gases Plant, 0.0518 mmlbmols/day • Air Separations and Syngas Plant will supply 0.004 mmlbmols/day of O2 for the Oxy Booster in ration (0.9 O2 : 0.1 N2)

  11. Energy Sources and Sinks

  12. Equipment Sizing Primary Reformer Tubes: 10 in. Diameter, 26 ft. length f = Maximum heat flux thorough tube walls = 21,000 Btu/ft2*hrd = Heat duty through primary reformer (from Aspen) = 279,515,872 Btu/hra = Total needed surface area of reformer tubes = d/f = 14,167 ft2t = a /73 ft2 per tube = 194 tubes needed

  13. Cost

  14. Transportation Costs By Rail For Feed/Product • Basis of 1.84mm ton produced 5,041 (ton/day) • Average rail car holds 80tons. With a maximum load per train of approximately 15,000ton and 150 cars • Plant will need a train every 2days of approximately 130 cars. • Average cost to ship by rail 0.03($/ton mile) • Assuming a discounted rate of 25% for large volume of material transported. • Using northeast Minnesota for iron oxide source and northwest Indiana for product shipment. • Cost to ship 23.00($/ton) to ship product 12.00($/ton) import raw material.

  15. Shipping/Storage • Installed equipment cost for a private rail line with loading/unloading site at our capacity will be around 15mil • Storage facility with installed in-loading/out-loading conveyor system, a negative pressure dust/ climate management system, and a 150ton capacity will cost around 10mil
