Description
本出願は、2007年8月30日出願の米国特許仮出願第60/966,796号の優先権を請求する。
薬剤の製造プロセス中に薬剤と直接接触することになるガスは、ICH Q7A、及び食品医薬品局の医薬政策の下で、医薬品自体と同じ高い国際品質規格を満たさなければならない。低温液体窒素は、医薬、及び生命工学の産業分野において医薬品の製造を促進するために段々と使用されるようになってきている。もし液体窒素が滅菌されていないと、抗生物質又はワクチンなどの医薬製品の最終的な調製において、直接接触冷却剤として用いることが出来ない。加えて、低温貯蔵施設はまた、液体窒素の滅菌性に関して監視下に置かれている。
a)廃ガスストリームを第1の熱交換器ユニットからろ過ユニットに供給し、ここでその廃ガスストリームを滅菌する工程;
b)その滅菌された廃ガスストリームを第2の熱交換器に供給し、ここでその滅菌された廃ガスストリームの温度を下げ、これによって滅菌低温流体を製造する工程;
c)滅菌低温流体を回収する工程;及び
d)第2の廃ガスストリームを第2の熱交換器から供給し、そしてその第2の廃ガスストリームを第2のろ過ユニットに供給し、ここでその第2の廃ガスストリームを滅菌し、そしてその第2の滅菌された廃ガスストリームを第3の熱交換器に供給する工程;
を含む、滅菌低温流体を製造するための方法が開示されている。
熱交換器を出る廃ガスストリームは、窒素、酸素、空気、及びアルゴンからなる群から選択される低温流体である。廃ガスストリーム及びガスストリームは、同一の種類の低温流体であっても、異なるものであってもいずれでも良い。
FOM=消費される窒素の量/製造される滅菌液体窒素の量−1
とする。
プロセスからの、清浄な、しかし滅菌されていないベント(廃)ガス(WG)はまた、その他の目的のために用いることが出来る。例えば、常温、加圧された窒素ガスは、タンクの不活性化及び圧力移送などの様々な目的のために用いることが出来る。このベントガスのいくらか、又は全てを、一般的な使用のために、プロセス施設内部の一般的なガス使用ヘッダーに直接供給しても良い。
