Description
二酸化炭素吸収液を用い、燃焼排ガスから二酸化炭素を除去・回収する工程としては、吸収塔において燃焼排ガスと二酸化炭素吸収液とを接触させる工程、二酸化炭素を吸収した吸収液を再生塔において加熱し、二酸化炭素を遊離させると共に吸収液を再生して再び吸収塔に循環して再使用する二酸化炭素の回収システムが採用されている。この二酸化炭素の回収システムは、吸収塔においてガス中に存在する二酸化炭素を吸収液に吸収させ、その後再生塔で加熱することで吸収液から二酸化炭素を分離し、分離した二酸化炭素は別途回収すると共に、再生された吸収液は再度吸収塔で循環利用するものである。リボイラは、再生塔にて吸収液を加熱して二酸化炭素を分離、回収するために用いられる。
また、リボイラは、液状冷媒と冷水との間で熱交換を行わせ、冷媒を気化させ、冷却された冷水を建物内に循環させる冷房に利用されている(特許文献2)。
長手方向の流路断面形状の最大の長さは、例えば、流路断面形状が円の場合は直径、楕円形の場合は長径、三角形、四角形、八角形等の多角形の場合は最も長い対角線である。
リボイラでの液体の処理量は、後続する工程での処理の性質や処理能力を考慮して決定される。
図5〜7は、液体の流路断面積が2m×3mの長方形で、その最大長さである対角線が3.6mである、図1のタイプの大型ボイラを用い、液体の流量50kg/m2s(伝熱管群出口)で118℃の液体を熱交換により123℃に加熱する場合の伝熱管群の配置を変化させたときの解析データを示す。図5〜7は、図1のA−A断面に相当し、各(a)〜(c)は、液体とその蒸気の混合物における蒸気の質量割合である蒸気クオリティが0.1以下の領域を塗りつぶして黒色で示し、各(b)は、図1のA−A断面の半分を記載して伝熱管群の配置を示す。
図6に示す実施例2は、伝熱管群の内部に上下方向に貫通する空隙を形成した例を示し、図6(a)に示すように、容器上部では蒸気クオリティが0.1を超える領域の割合が増加しているが、許容できる伝熱効率を示す。
図7に示す比較例1は、伝熱管群の配置を小型リボイラの配置と同様とした例を示し、図7(a)に示すように、容器上部では蒸気クオリティが0.1を超える領域の割合が大きく、低い伝熱効率を示す。
