Lewa has delivered a total of six Ecoflow type LDH5 process diaphragm pumps to the Arabian Gulf in order to expand the pumping capacity of two offshore gas fields. The pumps are used to inject mono ethylene glycol (MEG) to prevent bore hole icing at critical points along the pipeline. This job follows two earlier major projects. As part of the largest job in Lewa’s history, a total of 40 process diaphragm pumps for MEG injection were built for the end customer, an international company, in 2013. A follow-up order in the summer of 2017 included the delivery of 12 Ecoflow series type LDH5 pumps, among other products. The experience, gained on the two previous projects has helped to handle the current, third project with even more speed and efficiency.
The major order arrived at the end of March 2018. Its goal was to increase the pumping capacity of two offshore gas fields in Saudi Arabia. For this purpose, an international oil and gas company ordered a total of six Ecoflow type LDH5 process diaphragm pumps from Lewa. They are installed on wellhead platforms (WHPs) together with the corresponding M8 pump heads. From there, the pumps will inject mono ethylene glycol into the pumping process. This will prevent methane hydrates from accumulating at critical process locations, thereby effectively countering bore hole icing. “The six LDH5 pumps work with an operating pressure of approximately 520 bar and are designed for a flow rate of 5000 l/h,” said Klaus Figgle, Senior Project Manager of Engineering at Lewa. “As such, they are ideally suited for the application and contribute to complication-free gas pumping.”
As part of the cooperative effort with the end customer, this current major project represents what is now the company from Leonberg, Germany’s third MEG-injection project for the Arabian Gulf gas field. The shipment of 40 process diaphragm pumps back in 2013 (as part of what was previously the largest order in Lewa’s company history) was supplemented in 2017 by the follow-up order of 12 process pumps and 8 boxer pumps. The company received the letter of intent for the current project Lewa in May 2018, and the contract followed in July 2018. “Since the previous order involved the delivery of identical systems, we completed the project promptly and efficiently by November of the same year,” Figgle reported. “We were even able to shorten the delivery process of the first two systems by three weeks. The customer has expressed a high level of satisfaction with both the quality of the pumps and the course of the project.” The systems are currently being installed on the platform.
The implementation of the EU F-gas Regulation 517/2014 poses significant challenges for manufacturers, service providers and equipment operators. You as an operator need to be particularly aware of the changes to ensure timely planning of investments and optimal long-term decisions. After a thorough examination of the issue, Kaeser is offering operators supply security now and in the future with the switch to the climate-friendly refrigerant R-513A for all current and future models.
Food processing and packaging
Oil-free screw type vacuum pump
Leybold presents its innovative vacuum portfolio at the international trade fair for the meat industry IFFA in Frankfurt am Main from 04 to 09 May 2019 in hall 11, booth A41. The new Novadry vacuum pump series will be the focus of the presentation. The completely newly developed, oil-free screw vacuum pump ensures significantly greater safety and efficiency in food and packaging processes.
Vacuum as a key technology
The demands placed by manufacturers and consumers on the quality, shelf life and resource efficiency of food and packaging processes are constantly increasing. This applies even more to such perishable products as for example meat or fish. Vacuum is considered as an enabling technology, contributing significantly to optimizing these processes. Therefore, Leybold developed the innovative Novadry, a new 100% oil-free, air-cooled pump, which will be launched at the IFFA.
No oil, less effort
“Many users in meat processing and packaging cannot actually tolerate vacuum pumps emitting oil,” stresses product manager Niels Gorrebeeck. Novadry prevents such contaminations. That is why Leybold designed a 100% dry pump following hygienic criteria. This increases safety in applications such as tumbling, filling, vacuum packaging and thermoforming. An additional advantage of oil-free vacuum pumps is the lower cost of ownership, as less maintenance and spare part changes are required.
In addition to the oil-free screw principle, Leybold has transferred proven components and principles from other vacuum pump series to the Novadry, including the bearing structure and the belt drive, which synchronizes the rotors in the Novadry.
Broad range of applications
The Novadry also stands out due to its long uptime and robustness. Some competitor products lose their end-pressure or reduce pumping-speed due to wear of the inner coating, for example. The Novadry, however, achieves its performance over the entire pressure range and life cycle. This makes it ideal for simple applications, which emit low amounts of humidity, such as packaging of cold products. Moreover, the pump is also perfectly suited for more demanding processes with large amounts of water vapour, for example when hot meals with temperatures of up to 95°C have to be quickly cooled down by evaporative cooling. “In addition to the air/steam mixture coming from the process, the Novadry screw vacuum pump can also handle the anticipated contamination inside the gas flow very well. These are for example organic acids, spices, vinegar or other residues,” summarizes Pierre Lantheaume, Business Development Manager Food & Packaging at Leybold.
Proven in real life
Novadry has successfully passed many qualifying field endurance tests in a wide range of food applications – tumbling, tray sealing and thermoforming. In all applications, it shows very good performance, the users reached fastest cycle times and low final pressure.
Leybold have succeeded in developing a forward-looking product which has the potential to set a new standard for the food processing and packaging markets. This is due not only to the absence of oil, but also to the Novadry’s noise behaviour, the robust design and the low life-time costs.
