Title (EN) PROCESS FOR GASIFICATION OF COAL
(FR) PROCEDE DE GAZEIFICATION DU CHARBON
Abstract: front page image
(EN)Coarse, graded coal is fed to a pressurized relatively fixed bed, non-slagging gasifier (12) from which crude gas (26) is recovered. Fine coal is slurried (42) in an aqueous mixture comprising the discharge (38) from the relatively fixed bed gasifier (12), which discharge is composed of hydrocarbons, phenolic water and other liquids as major components and additional makeup water, if required, and the slurry is fed to a slagging, pressurized entrained flow gasifier (56) from which additional crude gas (60) is recovered. The two streams of gas are cleaned (36, 82) and then used to meet a variety of demands, including, but not limited to, gas turbine generation of electric power, manufacture of synthetic natural gas and manufacture of methanol. The two gasifiers are arranged for balanced parallel operation so that no liquid by-products and no phenolic waste water disposal problems are encountered.
(FR)Du charbon grossier, echantillone est introduit dans un gazeificateur pressurise, a lit relativement fixe, ne formant pas de scories (12) duquel du gaz brut est recupere. Des fines de charbon sont emulsifiees (42) en un melange aqueux comprenant le defournage (38) du gazeificateur a lit relativement fixe (12) lequel est compose par des hydrocarbures, de l"eau phenolique et d"autres liquides en tant que composants essentiels et de i"eau additionnelle de fabrication, si necessaire, et cette emulsion est introduite dans un gazeificateur, pressurise, a courant entraine (56) duquel du gaz brut additionnel (60) es recupere. Les deux flots de gaz sont nettoyes (36, 82) et sont alors utilises pour repondre a une variete de demandes, comprenant, mais ne se limitant pas a, la production d"energie electrique par turbine a gaz, la preparation de gaz naturel synthetique et la preparation du methanol. Les deux gazeificateurs sont disposes pour une operation parallele, equilibree, afin qu"aucun probleme de destruction de sous-produits liquides ou d"eau phenolique residuelle ne se presente.
