Enhance the Plant Operating Capacity - Maximize the Revenue/Asset Utilization

To explore the opportunity for maximum utilization for a Sales Gas Compression Facility (SGCF) in line with ADNOC strategy to enhance profitability and asset utilization. A technical study was conducted to increase the processing capacity up to 133% of its design limit by utilizing the available design margins. This was to identify the potential bottlenecks in the facility and suggest debottlenecking options (if bottlenecks are there). The Technical study covered the following activities: Simulation: Process simulation was performed and H&MB (Heat and Material Balance) was generatd. Engineering: Compressor adequacy checks on increased plant throughputs. Static Equipment rating and adequacy checks performed with the concurrence of original equipment menufacturerers. Line sizing adequacy checks and detailed evaluation of the piping. Adequacy check for In-line instruments like control valves, flow elements/transmitters (Note 1) Relief, blowdown and flare system adequacy check. Utilities adequacy checks. Risk assessment workshop was conducted before the capacity test run. Preparation of Test Run procedure before the actual test run. Actual plant capacity test run to verify the study findings. Note 1: Adequacy check of thermowells had been peformed separately prior to the study. It had already been established that the thermowells were adequate for the increased plant throughputs. The study has concluded the following observations for processing 133% of the design capacity Theoratically, the Sales Gas Compression Plant is adequate to handle the sales gas throughput up to 600 MMSCFD (2 running machines) considering the facts that Sales Gas Compressor suction pressure must always be kept at 32 barg through close monitoring by the operaters.If compressor suction pressure starts dropping below 32 barg, the study outcome would no more valid and the plant throughput would be reduced back to the original design capacity of 450 MMSCFD. Moreover, it was recommended to perform a field test run to validate the study outcome by following the Manageement of Change Procedure as applicable. Based on the successful 48 hours test run, it was established that the facility could handle the increased plant throughput of 600 MMSCFD by following the instructions given in the adequacy study.

Maximize Asset Utilization by Effectively Identifying and Removing Bottlenecks

ADNOC Gas Processing Ruwais NGL Fractionation plant receives and fractionates the NGL produced in upstream gas processing plants. After operation of newly designed upstream NGL plants, composition of NGL feedstock has become richer in Ethane and Propane. Consequently, nameplate capacity were reduced by~25%. In view of future increased NGL production, nameplate capacity of fractionation trains needs to be re-instated. Alternatively, a new fractionation train needs to be installed to accommodate additional NGL. To explore the opportunity for maximum utilization for existing trains, in line with the ADNOC strategy of enhancing profitability and asset utilization, a technical study was conducted to increase the processing capacity back to original nameplate capacity with lighter NGL composition. This was to identify the potential bottlenecks in the facility and suggest debottlenecking options with a reasonable investment. The Technical study covers the following activities: Simulation: Rigorous process simulation including the licensor units of DEO/Propane amine units Adequacy checks and identification of bottlenecks: Line sizing adequacy check and detailed hydraulic evaluation of the major piping Equipment adequacy check Relief & blowdown and flare system adequacy check Proprietary equipment/design evaluation of licensed units Adequacy check for In-line instruments like control valves, flow elements/transmitters, thermowells Rotating equipment adequacy checks performed with the concurrence from OEMs. Licensor Endorsement: Obtained the endorsement of AGRU licensor (Shell) for the increased flow rate with revised contaminant levels with recommendations of removing identified bottlenecks. Bottlenecks mitigation: Various options for bottleneck mitigation was studied and most optimum solution was selected to remove the identified bottleneck. The study has concluded that current capacity limitation was mainly due to bottlenecks in Ethane loop. Therefore, by mitigating the identified bottlenecks (i.e. replacing lines with bigger size, providing high performance trays, high performance internals, replacing few equipment's with new one etc.), the original nameplate capacity can be re-instated. The study concludes that increased NGL forecasted flow with lighter composition could be processed in existing Ruwais fractionation trains by doing minor modifications (as compared to new train). A capacity increase of ~25% was achieved with minimum investment and requirement of new fractionation train could avoided. If extensive adequacy studies are carried out to identify the bottlenecks, the capacity enhancement in existing facilities can be achieved with minimum investment and major cost for new plants/trains can be avoided.

Awareness about Nanotechnology among Upcoming Clinicians in Vidarbha, Maharashtra

The making of new things at an incredibly small “nano” scale (100,000 times smaller than the human hair) is called nanotechnology and it is one of the most exciting and fast-moving technology in today’s world. Scientists and engineers have been working hard to make the maximum utilization of this knowledge towards applications like cure for certain diseases, to create certain renewable sources of energy and to bring human race safety into next millennium, thus nanomedicine being one of the most important evolution of nanotechnology. In this research, we have done a cross sectional observation, knowledge, perception and attitude study among 56 residents of various clinical departments of Datta Meghe Medical College. According to our survey, it was evident that only 48.21% of the residents were aware of the science of nanotechnology. Television was the source for most of them to know about it. Approximately 35.71% knew the size of nanoparticles which is really low. Of all the residence who knew about nanotechnology, most of the (42.86%) them knew about its application in healthcare whereas comparatively less (28.57%) were aware of its applications in areas besides healthcare. As expected very few (14.29%) had practically used this advanced science in health care. And hardly any knew about limitations or long-term side effects of nanotechnology in health care but most of them supported it. With our limited analysis and discussion, we could conclude that awareness and knowledge about nanotechnology among residents who are our upcoming clinicians, was deficient in more than half of them and inadequate among those who had. Universities need to add this subject in their curriculums and have an interdisplinary approach towards this recent advance so that all the medical students and upcoming clinicians have awareness and adequate knowledge regarding nanotechnology & nanomedicine which is going to be the future of medicine having significant impact on our health, comfort and lifestyle.
