Clean Hydrogen Energy and Electric Power Production with CO2 Capturing by Using Coal Gasification

Abstract

<em>Clean hydrogen is the major energy carrier for power production. The conversion of CO to CO₂and zero emission during hydrogen energy production cause</em><em>s</em><em> high capital cost. It is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. In this era, coal gasification is the most promising technology for the clean hydrogen energy and electric power production with simultaneously capturing of CO₂. The experimental set up used in this scheme consists of Fluidized </em><em>Bed Coal Gasifier (FBCG), syngas treatment unit, electricity generation unit, CO₂capturing unit and </em><em>clean hydrogen adsorption unit. This paper shows the analysis of low sulphur Makarwal (Pakistan) coal</em><em>. The</em><em> Oxygen to Steam (O/S) ratio is optimized in order to produce syngas efficiently </em><em>in the FBCG</em><em>. The</em><em> desulphurization unit</em><em> red</em><em>uce</em><em>s the </em><em>H₂S contents below than 1ppm</em><em>.</em><em> In this experimental </em><em>plant</em><em>, the</em><em> feed rate 3</em><em>7.5</em><em> tons/hr of coal is used and clean hydrogen is produced at the rate of 1.30-1.40 tons/h.</em>
