Abstract
Description
本発明による方法は、MSA水性溶液は鋼表面と接触する装置中で、メタンスルホン酸(H3CSO3H、MSA)水性溶液を取り扱う方法に関する。
使用された材料:
以下の試験のために、それぞれ水中70質量%MSAからなる溶液を使用した。それぞれ使用されたMSAのための製造方法は第1表にまとめ、第2表には分析データをまとめた。
試験を、1Lの平底ガラスフラスコ中で攪拌しながら実施し、MSA流をシミュレートした。固定のために上記鋼の種類の試験片(20mm×50mm×1mm)を使用し、この片は5mmの細孔を備えているものであって、超音波浴中で洗浄し、窒素ガス流で乾燥させ、かつ計量した。この片を、テフロンからなるホルダーにより、フラスコ中につり下げ、かつこのフラスコを密閉した。このフラスコ中のMSAを、マグネットステーラーを用いて750Upmで攪拌した。試験終了後に、この片を試験容器から取り出し、その際、完全脱塩水で洗浄し、吸収紙で注意深く拭き取り(粗い腐蝕性生成物を除去するため)、再度、完全脱塩水で洗浄乾燥し、かつ計量した。試験期間は、それぞれ7日間であり、温度は23℃であった。鋼番号4の場合には、試験期間は1日であった。
Claims (6)
- MSA濃度50〜99質量%および全塩素含量50mg/kg未満を有するメタンスルホン酸(MSA)水性溶液を、MSA水性溶液と鋼表面が接触する装置中で取り扱う方法において、当該鋼が、クロム含量15〜22質量%およびニッケル含量9〜15質量%を有するオーステナイト鋼であることを特徴とする、前記方法。
- 鋼がさらに1〜5質量%のモリブデンを含有する、請求項1に記載の方法。
- 鋼がさらに0.1〜2質量%のチタンを含有する、請求項2に記載の方法。
- 取り扱いの間におけるMSAの温度が40℃未満である、請求項1から3までのいずれか1項に記載の方法。
- 水性溶液中のMSAの濃度が60〜80質量%である、請求項1から4までのいずれか1項に記載の方法。
- 装置が、タンク、貯蔵容器、タンク列車の釜、タンカートラックの釜、タンクコンテナ、反応釜、計量供給装置、管路、フランジ、ポンプまたは計器および調整部材である、請求項1から5までのいずれか1項に記載の方法。
