Ensuring optimal plant performance with ORYX GTL

Topsoe’s cooperation with ORYX GTL in Qatar is a story of ambitious goals, technical advances and shared determination.

在抵达Ras Laffan Industrial City的Qatari Capity Of The Doha的Qatari Capital的高速公路射击了80公里，这是一个庞大的工业中心，在那里，Topsoe帮助实现了全国野心。在这里，我们是国有卡塔尔石油（51％）与南非的能源和化学品公司Sasol Ltd（49％）之间的合资企业。Topsoe专有的设备，催化剂，服务，工程设计和许可技术都参与了2006年在卡塔尔岛2006年在Ras Laffated的Oryx Gas-incation（GTL）设施。当时，该工厂携带了大约十亿美元的价格标签，是其最大的标签 - 迈向卡塔尔表示成为“世界GTL资本”的雄心壮志的最大阶段。“今天卡塔尔是世界上GTL中心，”商业发展经理Albert Van Wyk表示，他们在卡塔尔的Oryx GTL工作。“世界上九十九十九十条在这个国家制造。”

最佳性能 - 在路上和工厂

GTL Diesel is the primary product of the ORYX GTL plant, which also produces GTL Naphtha and liquefied petroleum gas (LPG). The feedstock for these products comes from Qatar’s enormous offshore reserve of natural gas, which is brought up from below the Gulf north of Qatar and transferred into the industrial city at Ras Laffan. As a transportation fuel, GTL Diesel is known as a premium product with a high cetane number, a low content of sulfur and aromatics and good cold flow characteristics. Its high quality makes it well suited to modern diesel engines; vehicles that run on GTL Diesel have substantially fewer emissions and much less engine wear. And while ORYX GTL produces fuels that perform optimally on the road, Topsoe is working with ORYX GTL to ensure optimal performance at the production plant.

停工每天可以花费数百万美元

Topsoe对Oryx GTL设施的主要贡献是工厂的合成气技术，包括自动改革器（ATR），其中天然气催化转化为合成气。

After this reforming, the synthesis gas is converted to wax using a process called low-temperature Fischer-Tropsch (a technology licensed by Sasol). Finally, the long carbon chains of the wax are hydrocracked (a technology licensed by Chevron) to become high-quality GTL Diesel and other liquefied products.

t Topsoe天然气重整过程中是非常重要的o the ORYX GTL plant. If something goes wrong with the ATR (or any other major element in the syngas process), it can shut down the entire operation while repairs are made. And that means loss of revenue while production stands still. “Every day of production means literally millions of dollars,” says Albert. “ORYX GTL is highly profitable, even by Middle Eastern standards.”

解决“出牙问题”和计划计划的停止

作为世界上善良的商业规模设施，Oryx GTL工厂经历了Albert称之为“出牙问题”的开始。在植物调试期间，

Topsoe与Oryx GTL密切合作，以监测和解释从工厂收集的数据，丹麦Topsoe O FFI CES的技术专家呼吁为技术查询提供快速响应。TopSOE设计了ATR以低蒸汽与碳比一起操作，以便创造最佳的合成气质量。然而，其中一个挑战涉及一个称为CTS燃烧器的ATR组件，该燃烧器由于腐蚀而遭受物质损失。这减少了合成气单元的操作时间。今天，重新设计的燃烧器已被优化，以成功执行2 - 3年，并且此经验的学习已经在埃斯卡拉维斯的另一个GTL项目中实施，

尼日利亚。前进，Topsoe和Oryx GTL继续调查新的优化可能性，通常在植物仿真的帮助下。

An example of how unplanned stops are being minimized is a Topsoe innovation that can automatically place the ATR in a so-called ‘safe mode’ if operational problems begin to develop. The ‘safe mode’ slows down operations to 90-95% of full capacity before the problem becomes critical, allowing technicians to make necessary adjustments without a full-scale plant shutdown.

最大限度地降低周转的成本

上述类型的无计划和相对较短的生产停工是一回事。

Another optimization challenge has to do with what is known as a ‘turn-around’: a planned shutdown of up to 50 days or more, during which time maintenance is performed, components are replaced and the plant is thoroughly checked. Turnarounds are hugely expensive, both in terms of logistics and lost production time. They are also a fact of life in this business – but Topsoe is currently supporting ORYX GTL with an optimization project to extend the normal time between turnarounds from two years to three. It’s a long-term and highly ambitious goal that involves optimizing every critical plant component for maximum life. For Topsoe, this means that each critical component in the ATR portion of the plant is regularly tracked using a color-coded system to indicate whether it is living up to its projected life expectancy. As component performance is optimized, the graphic expression of this tendency moves from red to yellow to green. Albert is pleased with Topsoe’s increasingly ‘green’ contribution to the turnaround goal: “Haldor Topsoe is instrumental in achieving this goal by focusing on technical enhancement to lengthen the operational lifetime of each component. The ATR technology is on track to increase the shutdown intervals from 2016 onwards,” he says.

新的客户协议更好地进行了良好的合作

2013年5月，通过五年的客户服务协议进一步加强了TopSOE和Oryx GTL之间的合作。在IT中，oryx gtl保证快速，24-7访问Topsoe的技术支持团队，以一致的速度。同时，Topsoe在Oryx GTL上留意计划的维护项目，因此还可以保证备件和催化剂的准备好供应。定期优化会议在卡塔尔和丹麦中举行，其中管理和技术人员可以让彼此了解需要解决的任何问题。该会议还旨在使ORYX GTL旨在了解在Topsoe上实现的任何新的技术突破，可以提高卡塔尔植物的表现。在新合同中保证了访问任何和所有此类改进。

“持续改进是oryx gtl的值之一，”阿尔伯特说。“优化工厂始终是寻求改善整体植物效率的持续优先级。”当然，Topsoe仍然致力于使最佳性能成为可能。

关于卡塔尔

The State of Qatar is a 4,416 sq mi. peninsula that extends into the Persian Gulf from the eastern side of the Arabian Peninsula. It shares a border to the south with Saudi Arabia and has a population of about 2.27 million, of which approximately 15% are Qatari nationals. A former pearl fishing center, Qatar has in recent years experienced explosive growth and is now one of the richest countries in the world, thanks in large part to its enormous oil and gas fields. The capital city of Doha is, among many other things, home to the satellite TV station Al-Jazeera; in 2022, Qatar
