Enhancing the reliability of sulphur plant starts in the thermal stage. Matt Coady and Martin McCallister of Delta Controls report on a recently developed and launched insertable process camera that monitors the vessel interior of online Claus thermal reactors, providing valuable process data which will allow plants to make better informed operation decisions.
Operating plants in extreme environments can present unique challenges. If these challenges are not anticipated and addressed in design and commissioning, the plant will not be able to start up nor meet its specification. This article examines the challenges faced in commissioning amine plants operating in three diverse environments (extreme heat, extreme cold, and offshore) and the technical and procedural solutions employed to resolve them. Mike Sheilan, Ben Spooner, Kaiyr Tekebayev, and Philip le Grange , Amine Experts.
Inshan S. Mohammed of Sulfur Recovery Engineering shares lessons learned from a recent SRU shutdown assistance programme involving an error with the tags used within the BMS system installed on a direct-fired reheater.
Condensate formation in sulphuric acid plants can cause severe corrosion problems leading to high maintenance and plant downtime. Santhosh S . of Metso Outotec discusses the importance of carrying out regular monitoring and maintaining accurate and detailed data about condensate to increase equipment life and avoid downtime. Different sources of condensate formation in the plant are discussed as well as the typical locations in the plant where the condensates end up.
Jochen Geiger of AMETEK Process Instruments reviews SRU process analyser standards, how to choose the right instruments, what to watch out for when selecting the point of installation, responsibilities for the analysers after installation, and how to make best use of the information provided by these analysers. Potential upset conditions and how analysers can help us to understand and mitigate them are also discussed.
New innovations, services and latest technologies to improve the operation and reliability of steam methane reformers from AMETEK Land, Kontrolltechnik, BD Energy Systems, Koch Engineered Solutions, and Quest integrity.
Temperature monitoring and measurement of the Claus thermal reactor in sulphur recovery units is one of the most challenging applications in the oil and gas industry. Recently, market interest in unpurged thermocouples has increased with the introduction of new unpurged thermocouple designs utilising alternative thermowell materials such as monocrystalline sapphire.
Several safety risks threaten urea high pressure equipment such as high pressures, high temperatures, various kind of corrosion phenomena, crystallisation risks, and the release of large volumes of toxic ammonia in case of a leak. A significant number of serious incidents with high pressure urea equipment still occur in the industry and, in 50% of cases, a failing leak detection system was one of the main causes. UreaKnowHow’s Risk Register for a 316L urea grade reactor identifies 50+ safety risks of which 75% can be prevented by operating a proper leak detection system. In this article, UreaKnowHow answers some key questions about the importance of an effective active leak detection system.
An industry-wide push for greater environmentally accountability is driving the need for improved fertilizer cooling methods. Not only is indirect cooling technology more environmentally-friendly, says Igor Makarenko of Solex Thermal Science, it also provides fertilizer manufacturers with a better product.
A. Bhargav and A. Krishnan of Helium Consulting Pvt. Ltd discuss how it is possible to reduce SOx emissions within the existing system setup of an oil refinery or gas plant through detailed analysis, expedited corrective actions and the use of automated algorithms in real-time, by using a digital IIoT solution to monitor, control and optimise.
