Description
・ 処理からの水蒸気の流れ(17)は、炭化水素供給原料(1)との混合物として水蒸気改質反応器(25)に送られ、その流れは、水蒸気(17)対炭化水素供給原料(1)の比が1.5〜3の範囲、好ましくは1.5〜2の範囲の値に調整されるように制御され;
・ 生じた残りの水蒸気(21)を、圧縮機(32)と関連する蒸気タービン(33)に供給するために用い、前記圧縮機(32)に供給する空気流(20)は、煙道ガス回路(35)上において交換機(7−1)および(6−1)の下流に置かれた弁(36)によって、圧縮機(32)の作動圧力が3〜5絶対バールに調整されて、前記圧縮機の特性曲線上に留まるように制御される。
本発明は、高純度の水素、すなわち少なくとも99.5%(重量による)の純度の水素の製造方法であって、燃焼室によって生じた、圧力下の高温煙道ガスを伝熱流体として用いる交換器−反応器において炭化水素留分を水蒸気改質することによる、方法として定義され得る。従来技術の方法の全てと比較して、本発明の方法は、本方法の要件(すなわち、一方で、炭化水素供給原料の水蒸気改質に必要な水蒸気、他方で、伝熱流体を加圧するための圧縮機を駆動することができる水蒸気タービンのためのエネルギーの供給)に厳密に相当する量の水蒸気を発生させる。
・ 本処理からの水蒸気の流れは、ライン(17)を経て、ライン(1)からの炭化水素供給原料との混合物として水蒸気改質反応器(25)に送られ、その流れは、ライン(17)からの水蒸気対ライン(1)からの炭化水素供給原料の比が1.5〜3の範囲、好ましくは1.5〜2の範囲の値に調整されるように制御され;
・ 生じた残りの水蒸気は、ライン(21)を経て、圧縮機(32)と関連する蒸気タービン(33)に供給するように用いられ、前記圧縮機(32)に供給する、ライン(20)からの空気流は、煙道ガス回路を示すライン(35)上において交換器(7−1)および(6−1)の下流に置かれた弁(36)によって、圧縮機(32)の作動圧力が3〜5絶対バールに調整されて、前記圧縮機の特性曲線上に留まるように制御される。
本発明の方法の適切な理解のために、図1のフローチャートを説明する必要がある。このフローチャートは、最も近い従来技術を構成するHygensys法を示す;本発明は、サイトが水蒸気を必要とせず(水蒸気改質方法自体によって要求された水蒸気を除く)、電気も必要としない状況への適応として見られ得る。
供給原料、好ましくは、天然ガスは、ライン(17)を介して到達する水蒸気との混合物として、ライン(1)を介して交換器−反応器(25)に送られる。
