Currently, KSB supplies the SEZN vertical mixed-flow pump for China's largest liquefied gas center that was started in Hainan and is expected to be delivered by the end of 2013.

Today, global attention to liquefied gas has generally increased. This natural gas resource is transported from the pumping site to an LNG (liquefied natural gas) dedicated receiving station located near the coast or near the port. Natural gas is high pressure cooled to -164°C in an LNG receiving station and stored. During the cooling process, natural gas is converted from a gaseous state into a liquid state and becomes LNG, a liquid natural gas. After that, the liquid natural gas is pumped to a special container and transported to other LNG receiving stations, where it is converted back to gas.

With the Asian economy, especially the growth of China’s economy, the demand for energy has generally increased, and the demand for natural gas has also continued to increase. This means that more and more LNG receiving stations have started construction. For example, China National Offshore Oil Corporation (CNOOC) is building a large-scale receiving station in the western part of China's Hainan Province, which is expected to be put into use in August 2014. The receiving station currently under construction is located in the Yangpu Economic Development Zone. Once completed, it will produce 2 million tons of liquefied gas each year. By 2016, the annual output will reach 3 million tons, making it China's largest LNG center.

The SEZN pump unit provided by KSB will be equipped with Residur ceramic bearings, and the components that come into contact with the medium are all duplex stainless steel. The pump unit is used to process the large amount of seawater needed to heat liquefied natural gas. This process can convert liquefied gas to a gaseous state.
