１．合成ガスを製造するための方法であって、以下のステップ：
ａ）改質セクションにおいて炭化水素供給材料を改質し、それによってＣＨ４、ＣＯ、ＣＯ２、Ｈ２およびＨ２Ｏと、アンモニアを含む不純物とを含む合成ガスを得るステップ；ｂ）前記合成ガスを、１または複数のシフトステップを連続して含むシフトセクションにおいて、シフト合成ガスにシフトさせるステップ；
ｃ）前記シフト合成ガスから、前記シフト合成ガスの冷却および任意選択的に洗浄から生じるプロセス凝縮物を分離するステップ；
ｄ）前記プロセス凝縮物の一部を凝縮物蒸気ストリッパーに通すステップであって、前記合成ガスのシフトの間に形成されたアンモニア、メタノールおよびアミンを含む溶存シフト副生成物を蒸気を用いてプロセス凝縮物からストリッピングし、ストリッパー蒸気流をもたらすステップ、
ｅ）プロセス凝縮物蒸気ストリッパーからの前記ストリッパー蒸気流を、前記炭化水素供給材料に、および／または前記改質セクションの下流かつ最後のシフトステップの上流で前記合成ガスに添加するステップ、

The amount of purge condensate is adjusted to remove all or a portion of the amine and ammonia formed in the reforming and shift sections. For partial removal, residual amine and ammonia can be removed by passing acceptable levels of amine and ammonia into the reforming section via stripper steam from a condensate steam stripper.
Note that this application relates to the invention described in the claims, but may also include the following as other aspects.
1. A method for producing synthesis gas, comprising the following steps:
a) reforming the hydrocarbon feed in a reforming section, thereby obtaining a synthesis gas comprising CH4, CO, CO2, H2 and H2O and impurities including ammonia; b) converting said synthesis gas into one or more in a shift section including a plurality of consecutive shift steps, shifting to shift syngas;
c) separating from said shifted syngas process condensate resulting from cooling and optionally washing of said shifted syngas;
d) passing a portion of the process condensate through a condensate steam stripper, the process comprising using steam to process dissolved shift byproducts including ammonia, methanol and amines formed during the syngas shift; stripping the condensate and providing a stripper vapor stream;
e) adding the stripper vapor stream from a process condensate vapor stripper to the hydrocarbon feed and/or to the synthesis gas downstream of the reforming section and upstream of the last shift step;
wherein the remainder of the process condensate is purged.
2. 2. The method of claim 1, wherein the condensate vapor stripper is a medium pressure stripper.
3. 3. A method according to claim 1 or 2, wherein the purge is passed through a purge condensate vapor stripper.
4. 4. A method according to any one of claims 1 to 3, wherein the purge condensate vapor stripper is a low pressure stripper.
5. 5. A method according to claim 3 or 4, wherein the vapor from the purge condensate vapor stripper is condensed and the non-condensable gas is used as fuel.
6. 6. A method according to any one of 1 to 5 above, wherein the stripped condensate from step (d) is passed through a water treatment.
7. A method according to any one of claims 3 to 6, wherein the stripped purge condensate from the purge condensate vapor stripper is passed to a water treatment.
