2 GPA Europe Young Professional Training Day, 2015 Introduction In line with their commitment to providing excellent training opportunities for younger professionals in the Natural Gas Processing Industry and further to attract current students to consider natural gas processing as a challenging future career, GPA Europe, will hold a special Training Day at the Manchester Conference Centre, close to The University of Manchester on February 12, 2015, The Training Day has been specially formulated to, wherever possible, have a pair of presentations from Academia and Industry on the same subject to present the current state for research and then offset that against the current best practice in design and issues that need to be considered. The programme will commence with an outline of the current and future state of the global Natural Gas industry for John Sheffield, a world-respected commentator and consultant and ex-chairman and stalwart member of the GPA Europe. Topics to be discussed during the day will include the use of heat integration in low temperature plant design, glycol dehydration, sweetening and the design of LNG Vapourisation systems. All attendees will receive a Certificate confirming their attendance at a training event which can be provided as evidence of Continuing Professional Development. Who should attend? Young Professionals who have recently joined the Natural Gas Processing industry Students considering Natural Gas Processing as a career Engineers wishing to update their knowledge of specific aspects of Natural Gas Process design What is Included? Coffee on arrival, mid-morning and mid-afternoon, Print-outs of Presentations, Lunch, and a free Bar at end of the afternoon What does it Cost? NOTHING. GPA Europe will fund this meeting for employees of members companies and students as part of its continuing commitment to Young Professional training and as a means of introducing young engineers and students to the benefits the Gas Processors Association can bring them as their career progresses. Delegates from non-member companies are welcome to attend for a fee of Accommodation can be arranged at the Pendulum Hotel attached to the Conference Centre, if required and details of how to get preferential rates will be provided on registration. * Free to employees of member companies and students.

3 GPA EUROPE YOUNG PROFESSIONAL TRAINING DAY 12 February 2015 PROGRAMME Morning Session Chairman: Paul Openshaw, Enerflex Chairman of GPA Europe Challenges and Future of Natural Gas John Sheffield, Petroskills Natural gas is probably the most environmentally friendly fuel available today for providing power for a secure and comfortable world. Yet the consumption of gas as a fuel for power generation is being displaced by burning cheap coal. This does not make sense! The background to the development of the natural gas industry is explored with specific reference to European demand. The uses of natural gas for power generation, industry and domestic use are explained and the potential opportunities for new uses as a transportation fuel are considered. The sources and demand for natural gas are explored and the means of delivering gas by pipeline or as LNG by ship will be explained : Energy Efficient Low Temperature Low Energy Distillation Columns Design of energy-efficient low-temperature distillation systems Megan Jobson School of Chemical Engineering and Analytical Science, The University of Manchester Distillation is a very widely used and versatile process for purifying mixtures of chemicals, e.g. natural gas liquids, to recover valuable products. However, the process is very energy intensive, especially when applied to recover low-molecular-weight species such as ethane, propane and butane from hydrocarbon mixtures. To separate these species by distillation requires highpressure operation and/or low-temperature cooling, incurring significant operating costs. The most significant energy demand is related to the need for low-temperature cooling using refrigeration processes. Per unit of energy, refrigeration is increasingly expensive as the temperature decreases; in addition, refrigeration cycles become more complex and costly as temperatures decrease. The compression power requirements for a refrigeration system can be significantly reduced if heat removal after compression can be carried out at a low temperature, thus reducing the compression ratio in the compressor. Distillation column reboilers can provide a convenient sink for this rejected heat. Especially where low-temperature refrigeration is needed, the compression power requirements can also be reduced by providing cooling at more than one temperature level or using mixed refrigerants. This talk will provide an overview of how distillation column design and performance and refrigeration cycle design and performance interact with each other and how the overall distillation-refrigeration system can be designed to maximise productivity while minimising energy consumption. The concepts and methods will be supported by case studies.

4 1130 A New Process for Improved LNG Production Efficiency Adam Jones & Grant Johnson, Costain Energy & Process Liquefied Natural Gas (LNG) production plants need to operate with low specific power consumption (per unit of LNG) to maximize LNG production and plant profitability. The plant design with the highest liquefaction efficiency is not always the best as other factors are significant in optimizing a plant design. Even so, maximizing LNG production is important for all liquefaction plants so high liquefaction efficiency is valuable. Liquefaction efficiency depends on several parameters, some of which are fixed and some of which can be optimized by the process design team. High feed gas pressure increases LNG production and plant operating pressure is one of the most important parameters that the process design team can optimize. Heavier hydrocarbons are normally removed to avoid freezing (possibly along with natural gas liquids (NGL)) and the feed gas pressure has to be limited to less than about 45 bar to permit NGL fractionation and for liquid product to be separated from the feed gas. This fractionation therefore limits the maximum feasible pressure for liquefaction and hence the efficiency and performance of the liquefaction process. This paper describes a new process that removes the limitation imposed by fractionation pressure as the feed gas can be conditioned for hydrocarbon liquids removal and subsequently increased in pressure as an integrated part of the liquefaction process. The process combines simplicity and operational performance with high liquefaction efficiency via a minor but novel adaption of conventional liquefaction processing Networking Lunch Afternoon Session Chairman: Simon Crawley-Boevey, GE Oil and Gas : LNG Vapourisation Heat integration of Cold Energy from LNG Vapourisation Simon Perry, University of Manchester This presentation investigates the potential of thermal integration of the cold energy released by the vaporisation of LNG in power generation. Standard LNG receiving terminals often fail to recover this valuable low temperature cold energy. An investigation of potential integration schemes was based on a scheme consisting of a nonintegrated LNG receiving facility with a 630 t/h natural gas send-out and a 350 MW Combined Cycle Power Plant (CCPP). Overall all of the options considered provide economic gains by allowing increased power production from around 15 MW to 28 MW. Why cold energy from import terminals has not been widely implemented Brian Songhurst, Energy and Power The cold energy from the heat of vaporisation at LNG import terminals provides a value source of cold energy. However to date very few schemes have been implemented outside of Japan. Many studies have been undertaken but the recommendations are rarely implemented due to mainly to commercial considerations. These are usually associated with guaranteeing the cold supply or differences in agreeing a price on the cold energy i.e. the provider saying it has a value whereas the user saying it should be free as it currently wasted. In most cases the possible users have to put in back-up cold supply systems (refrigeration) to cover non-supply completely destroying the benefit Coffee Break

5 Amine Systems Justin Hearn BASF : Sweetening Natural Gas One of the most common ways of removing CO 2 and H 2 S from natural gas is by means of amine treatment. Understanding which AGR process technology to select for a particular application is very important, and the key to good plant economics, performance and availability. That, at least, is the theory, but what can be done to rescue the plant performance when things don't work out so well in practice? MEG Dehydration Nejat Rahmanian, University of Bradford : Glycol Dehydration Monoethylene glycol (MEG) is known as a thermodynamic hydrate inhibitor in the gas transportation system. The injection of MEG into subsea pipelines prevents the formation of hydrates and the rich MEG is re-circulated in the closed loop of MEG system in the offshore and onshore processing plants. The regeneration of MEG is performed in a unit where the rich MEG is transformed into the lean MEG by removing the absorbed water and contaminants to avoid the potential blockage in the subsea pipelines. In this study, the MEG regeneration process is simulated using Aspen HYSYS software to achieve 70 wt% of glycol concentration as the final product. The case study was an industrial plant located in the South Pars Gas Field (Assaluyeh, Iran). Influence of feed flow rate on the purity of the final product and steam consumption was also analysed. A new alternative of MEG regeneration including the full and partial salt reclamation is also developed and the results are compared with the conventional MEG regeneration unit. MEG Regeneration and Reclamation in Industry Tanzim Choudhury, Cameron The use of Monoethylene Glycol (MEG) to inhibit hydrate formation is well established in subsea wellheads and production pipelines. MEG is regenerated by boiling off the water, however the presence of saline formation water causes salts and other solid contaminants to build up in the MEG, promoting fouling of the reboiler section of the regeneration module. Corrosion, MEG degradation, MEG losses, and frequent shutdowns for clean-out and repairs become major issues. MEG regeneration and reclamation packages are designed specifically to remove salts and other solids while also removing the water to achieve the required outlet MEG purity. This presentation focuses on the key design aspects and challenges of MEG regeneration and reclamation systems End of Session Delegates are invited to a Free Bar after the event until 1900
