NGLTech wins two awards at OTC Asia 2018 for its innovative inventions
Malaysian local technology development company NGLTech Sdn Bhd has won two ‘OTC Asia Spotlight on New Technology Awards’ for the Small Business category for its Low Pressure Condensate Recovery System (LP CRS) and also the SEP-iSYS Cyclonic Sand Removal System (CSRS). The latter is jointly-owned and developed by Petronas.
NGLTech is the only Malaysian SME from the OGSE industry to win two of these awards in the Small Business category at the Offshore Technology Conference (OTC) Asia 2018 in Malaysia.OTC Asia 2018 is a four-day event that brings experts from all over the world to discuss and facilitate knowledge-sharing in the energy industry.
“Today, the industry is continuously challenged with finding novel approaches to meet tomorrow’s energy demands. Innovative techniques are needed to access hydrocarbon reserves in technically challenging reserves, stranded marginal fields to maximize production from mature oil and gas fields through cost-effective means. Therefore, investing in R&D is the key to drive innovation and create new and improved technologies,” NGLTech’s managing director Ir Arul Jothy said on the sidelines of the event.
“NGLTech provides cost-effective and integrated solutions, fast-track Engineering, Procurement, Construction and Commissioning (EPCC) delivery and significant OPEX savings to operators, whether it is for optimisation, a new project or an improvement to an existing facility by utilising and implementing field proven and techno-economic merit process solutions,” he added.
The Low Pressure Condensate Recovery System (LP CRS) is currently the only system in the world that is able to attract value hydrocarbon condensate from very low pressure gas including flare gas in a compact and self-contained unit suitable for both onshore and offshore facilities. The technology enhances the recovery of stabilised crude by 10% to 30% and reduces greenhouse gas emission by approximately 15% to 30%.
Consisting of a series of heat exchangers, a cold separator and a stabiliser column, the system uses the JT cooling coupled with evaporative cooling effect that reduces the temperature of associated gas to strip the heavy ends of the gas stream. The JT cooling effect is achieved either via a JT valve or a turbo expander. The condensate stripped after cooling is removed from the gas stream in the cold separator after which it is stabilised in the column. All the water knocked-out during cooling is reinjected into the cold gas stream prior to heat exchange with the inlet associated gas stream. The combination of JT cooling and the evaporation of water enables very efficient cooling of the inlet associated gas stream which is the key to the high performance of condensate extraction.
Meanwhile, the SEP-iSYS Cyclonic Sand Removal System (CSRS) is a compact system with a novel configuration that enables very efficient sand removal at highly transient multiphase flow conditions.
The system consists of a flow stabiliser device located upstream of a cyclonic desander to dampen transient multiphase flow conditions and perform coarse gas liquid separation, ensuring stable predominant liquid flow into the cyclone. A differential pressure control valve is located on the gas outlet of the flow stabiliser to maintain a fixed differential pressure ensuring optimum performance of the system even under severe flow pressure surges including during high turndown. A sand boot downstream of the desander is provided to accumulate removed sand. Where required, a sand accumulator can be provided for online removal of the sand and online sand washing facility.
