Flare networks are designed to handle the gas volume required to be flared. Most times, this flare networks are in close proximity but still have independent flare stacks, increasing risk to environment and cost on infrastructures. There is a need to integrate the flare networks in facilities within same area and through the application of Pinch Analysis concept, the resultant flare network can be optimized to give a system having optimal tail and header pipe sizes that will reduce cost and imp</span><span style="font-family:Verdana;">act on environment.

Purpose: The oil and gas gathering and processing facility of Kuwait Oil Company is built with a nameplate capacity of X MBOPD (thousand barrels oil per day) with 50% water cut. However, the facility was operating with a water cut of 35%. This comprehensive technical study was conducted to evaluate possibility of increasing oil processing capacity of this facility in line with current lower water cut and other operational flexibilities available in the facility without utilizing its design margin. Topic: This paper shares an innovative approach to increase name plate capacity of oil and gas processing facility utilizing available operational flexibility and operational margins with minor modification. It shares a case study where facility capacity is increased by around 19% without utilizing design margins of equipment or pipeline. Method: The study includes theoretical verification and analysis of all major equipment and piping to identify available capacity and limitation, in order to utilize available additional margin and to propose debottleneck options to overcome limitations. Achievement: The study confirmed that, facility name plate capacity can be revised from X MBOPD (with 50% w.c (water cut)) to X + 32 MBOPD (with: 45% w.c) minor modification in separator and utilizing margin available in feed specification ofdesalter trains. 展开更多
