Supply of FLOWSERVE Kit

Tender Number: 129/2023/TWR (TPC-1936-2023)

PA Ref Number: TPC-1936-2023

Tender Description

The design of the mechanical seal for the pumps installed in BAPCO Upstream oil field are double mechanical seal type due to presence of H2S. Between these two seals is pressurized a buffer liquid which would prevent H2S to come out if inboard mechanical seal failed, meanwhile the second mechanical seal, the outboard seal is holding the pressure. The pressure of the buffer or barrier fluid is higher as the pump discharge pressure, so in case of leak buffer fluid will act as a barrier to prevent pumping liquid contain H2S to come out. To pressurize the barrier fluid between the seal is used an external mobile pump. If the barrier fluid pressure starts decreasing due to inboard seal leak, it will be trigged an alarm to increase barrier fluid pressure. If not done, pump will trip, to avoid H2S gas to come outside pump seal chamber.

رقم العطاء: 6778 
عنوان المناقصة: توريد مجموعة Flowserve 

الوصف: إن تصميم الختم الميكانيكي للمضخات المثبتة في حقل نفط بابكو هو نوع من الختم الميكانيكي المزدوج بسبب 
وجود كبريتيدالهيدروجين. يوجد بين هذين الختمين ضغط سائل عازل يمنع كبريتيد الهيدروجين من الخروج في 
حالة فشل الختم الميكانيكي الداخلي، وفي الوقت نفسه، يحافظ الختم الميكانيكي الثاني، الختم الخارجي، على الضغط. 
يكون ضغط السائل العازل أو الحاجز أعلى مثل ضغط تفريغ المضخة، لذلك في حالة تسرب السائل العازل سيكون 
بمثابة حاجز لمنع ضخ السائل المحتوي على كبريتيد الهيدروجين من الخروج. للضغط على السائل الحاجز بين الختم يتم 
استخدام مضخة متنقلة خارجية. إذا بدأ ضغط سائل الحاجز في الانخفاض بسبب تسرب الختم الداخلي، 
فسيتم إطلاق إنذار لزيادة ضغط سائل الحاجز. إذا لم يتم ذلك، ستتعثر المضخة، لتجنب خروج غاز كبريتيد 
الهيدروجين (H2S) خارج غرفة ختم المضخة.

المعايير الإلزامية:
1. امتثال مقدم العرض للنطاق والمواصفات.
2. الشركة المصنعة المعتمدة للتطوير.
3. يتمتع المنتج المقترح من مقدم العرض بضمان لمدة سنة واحدة (1) على الأقل.
