Objective
RIPI-Rifsim has been development for simulation , optimization and design of reformer furnace which is used for syngas and hydrogen producing in industries.
The results and data which could be obtained from software (in specification sheets and graphs type) are as follow:
Product characteristics (containing :conversion, component flow rate, temperature and pressure) Combustion characteristics (containing: required Air, HHV and LHV of fuel , flue gas composition adiabatic flame temperature, heat released and...). Physical properties of process gas and flue gas Process gas characteristics (profile of pressure, temperature, rate of reactions, effectiveness factors, heat absorption and conversion versus tube length) Furnace performance (containing: heat transfer, heat absorption , tube temperature profile , max temperature of tube , flue gas temperature, heat loss, catalyst weight and ...) Introduction
In recent years, a lot of research has been done on effective using of natural gas and its conversion to valuable and easily transportable products such as methanol, liquid hydrocarbons and petrochemical feed. The first step in this process is conversion of natural gas to synthesis gas. So RIPI-Refsim has been developed for studying and optimizing of syngas and hydrogen production unit. Description
Reformer furnace use for producing hydrogen or synthesis gas in oil, gas and petrochemical industries.In this project, by considering various phenomena such as heat transfer (in tube side and furnace side) , kinetic, mass transfer, pressure drop and catalyst shape effect, proper model has been developed for furnace modeling.
The model precision has been tested using industrial data, then a windows based software has been developed for simulation of reformer furnace.
RIPI-Refsim could be used in three different modes (rating , simulation and design ) and provides heat transfer, hydraulic , kinetic , heat loss, pressure drop and fuel consumption optimization rapidly and with high accuracy.
RIPI-Refsim contains two modules, terraced wall and top fired, which simulates terraced wall and top fired reformer furnace respectively. This catalogue describe terraced wall module. |
