FLOW Model

Project Summary

Full Title: Chemical Engineering Process Simulation Platform - FLOW
Project ID: 131
Principal Investigator: Juan Ferrada
Brief Description: FLOW is a steady-state chemical process simulator. Modules have been developed for supply chain calculations, micro-economic calculations, and other calculations.

Purpose

Simulate steady-state chemical processes to support hydrogen infrastructure and transition analysis.

Project Description

Type of Project: Model
Category: Hydrogen Fuel Pathways
Objectives: Calculate transition infrastructure cost; calculate total infrastructure cost versus cost of raw material; conduct hydrogen systems analysis; analyze hydrogen infrastructure
Technologies Modeled: Steam methane reforming; wind; coal gasification; nuclear
User Inputs: Hydrogen production rate; coal feedstock; natural gas
Methodology/Approach: FLOW uses cost models developed by H2A; it may use cost models developed by HyTrans; FLOW can conduct sensitivity analysis; FLOW can conduct uncertainty analysis using Monte Carlo and Latin Hypercube sampling methods
Hardware/Software Requirements: Windows XP; FLOW
User Interface: FLOW has a DOS graphic interface that can interact with Windows XP. It is object oriented and each icon may represent a complete process or a single process element. Processes are represented by graphic flowsheets comprised of several unit operations links by connectors. A Windows GUI version is currently being developed. Sensitivity and uncertainty analysis are features of the FLOW program.
Outputs: Hydrogen production cost; hydrogen transmission cost; hydrogen dispensation cost; total hydrogen cost at the pump; emissions
Assumptions Inherent in Model: Most simulations are in steady state mode. It performs mass balances and energy balances may be added to the simulation. Cost and risk models can be added to a regular flowsheet. Python, an object oriented computer language, is used as the scripting FLOW language to develop process models.
Sensitivity Studies Facilitated: Mass flow rate; feedstock cost; energy cost
Milestones Supported:
  • Systems Analysis Milestone 21: Complete the Production Infrastructure Options Model.
    • Organization: DOE/EERE/HFCIT
    • Description: Determine total infrastructure cost for several scenarios that supports the introduction of 2,500,000 hydrogen fueled cars in seven US cities.
    • Completion Date: September 2007
