LEWA’s parent company NIKKISO has developed deep ultraviolet light emitting diodes (DUV-LEDs). They have got technical support from none other than both winners of the Nobel Prize 2014 in physics. In this whitepaper, Dr. Cyril Pernot (NIKKISO) explains the performance data of this new technology in detail and shows different DUV-LED applications.
Over the last decades, the pharmaceutical industry has invested a tremendous amount of resources and capital into the development of continuous processes to improve process efficiency and robustness. Approaches such as integrated downstream processes with multi-column continuous chromatography show promising results with increased throughput and reduced capital and operational expenses. Dr.-Ing. Kathleen Mihlbachler (LEWA Process Technologies, Inc.) presents aspects of process development and describes guidelines on how overcome technical barriers in the regulated environment of the pharmaceutical industry.
The pump piping system has to be designed carefully if positive reciprocating displacement pumps with high hydraulic power are installed. Improper layout can lead to abnormal high-pressure pulsation, cavitation and fatigue failure of pump, piping or components. In this whitepaper, Dipl.-Phys. Marco Klinkigt (LEWA) explains the advantages of LEWA developed 1-dim CFD software. The software tools give us the opportunity to design an efficient pump-piping and dampener device layout for economic and reliable operation.
Most applications in oil and gas industry run with diaphragm pumps. Their characteristics make them more suitable for the special requirements in this area than most other pump types. This whitepaper refers to several applications and devices in the oil and gas industry that are run with diaphragm pumps such as chemical injection packages.
The service life of rotating equipment is dependent upon the successful operation of their rolling element bearings. For successful operation, a bearing should be installed properly, provided with a contamination-free environment, and sufficiently lubricated or cooled. Submerged electric motor pumps (SEMP), operating at a cryogenic temperature in a liquid hydrocarbon environment, provide a rolling element bearing design application that meets these criteria.
In designing a pumping system, controllability using variable speed to adjust pump operation can help in achieving energy savings. Increasing rotational speed above normal line frequencies and using higher speed motors lead to more compact, lighter pumps. These smaller units result in smaller components as well as lower installation and maintenance costs. Using variable speed with centrifugal pumps is nothing new, but with submerged motor cryogenic pumps, it is now becoming more widespread due to the need to reduce costs.
Lower capital costs, shorter on-stream time, lower coastal environment impact and flexibility – these are some reasons that led to the development of the floating storage and regasification unit (FSRU). NIKKISO Cryo is dedicated to the LNG industry and has heavily invested in technologies to advance FLNG including FSRU, FPSO and SRV operations. The company's packages include the full range of in-tank, send out and line packing pumps proven in the field. Original technologies addressing the specificity of operation during ship motion have been developed, patented and successfully validated.
Submerged motor pumps (SMPs) are designed versatilely: The same basic pump configuration, with all of its features and benefits, can be adapted in a variety of ways to meet various process, transport, transfer and storage applications in various static or dynamic installations. Benefits include zero emissions, high safety and the availability of high speed designs and variable speed control.
LNG facilities are built with state-of-the-art equipment and safety controls. The industry’s highest priority has always been safety and security, which is reflected in its impressive safety record. NIKKISO Cryo’s cryogenic pump testing facility is utilized to provide performance and mechanical tests for submerged motor cryogenic pumps for engineering purposes for development, engineering tests for production and Factory Acceptance Tests (FAT) for customers. Furthermore, NIKKISO Cryo uses an integrated management system to improve quality, safety and environmental performance in a process and systems approach.
