Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.

Abstract (eng): Gasification is a technologically advanced, environmentally friendly and proven technology for disposing high sulphur heavy fuel oils by converting them into clean combustible gas products, avoiding corrosion problems and environmental emissions.
Due to the high sulphur content of heavy fuel oil, it is essential to find efficient technologies to remove H2S from synthesis gas prior to its utilization within gas engines for power generation, since their absolute H2S limit is 500 ppm.

This thesis intends to provide realistic solutions for clean power generation and simultaneously for the problems of heavy residues in refineries.
For this purpose different approaches were adopted and presented.
In the literature part, several technologies to remove H2S from synthesis gas were reviewed, such as absorption, adsorption and catalytic hydro treatment.
In the experimental part a complete process of gasification, syngas purification by means of absorption and power generation was modeled and simulated with ASPEN plus.
Moreover, the overall performance was studied and an economic study based on CAPEX/OPEX was performed in order to evaluate the feasibility of the process and provide reliable results.
