传统上，海上石油平台的电力需求是由平台上的燃气轮机提供的。为这些涡轮机提供燃料的天然气通常是从产出的石油中分离出来的。然而，随着石油产量的下降，老化油田的伴生气也在减少。最终，天然气供应不足；为了继续生产，燃料是高价进口的。本研究提出，平台的电力需求可以通过平台上的ORC（有机朗肯循环）来满足或补充，该ORC由共同生产的热盐水提供燃料。这可以延长石油平台的使用寿命，降低成本和排放。ORC的潜在功率输出以北海布伦特省的油田为模型。结果表明，6个油田有潜力通过热盐水为燃料的有机朗肯循环产生超过10兆瓦的电力，其中niinian油田预计最大发电量为31兆瓦。对Eider油田的模拟分析表明，ORC工厂可以扩展到尺寸限制。10兆瓦ORC的成本与继续使用燃气轮机的成本进行了比较。如果不考虑温室气体排放税，预计ORC的投资回收期在3.09年至4.53年之间。(C) 2014 Elsevier Ltd.版权所有。
Traditionally the power demand of offshore oil platforms is delivered by on-platform gas turbines. Natural gas to fuel these turbines is usually separated from the produced oil. However, in ageing fields as oil production declines so does the associated gas. Ultimately gas supply becomes insufficient; in order to continue producing fuel is imported at great expense. This study proposes the power demand of a platform could be met or supplemented by an on-platform ORC (organic Rankine cycle) fuelled by coproduced hot brines. This could extend the operating life of oil platforms and reduce both cost and emissions. The potential power output of an ORC is modelled for fields in the North Sea's Brent Province. Results show 6 fields have the potential to generate more than 10 MW via an organic Rankine cycle fuelled by hot brines, with a maximum of 31 MW predicted for the Ninian field. Analysis of simulations for the Eider field shows that ORC plants can scale to size constraints. The cost of a 10 MW ORC is compared to cost of continued use of gas turbines. Payback times of between 3.09 and 4.53 years are predicted for an ORC, without accounting for greenhouse gas emissions levies. (C) 2014 Elsevier Ltd. All rights reserved.
