【Ten Years of Rapid Development in Chemical Processing Equipment】Shenyang-made low-temperature ethylene pumps for Zhongyuan Petrochemical, 1982–2017

Thread Content

There has been significant development in chemical processing equipment over the past decade; we praise the prosperity and strength of modern China. Wishing everyone a happy New Year, and may their families enjoy peace and good health. By contributing our ideas, we can create a more lively discussion environment. HaiChuan becomes even better with your participation – we encourage everyone to engage more actively in discussions on this forum. Low-temperature ethylene pumps are used to transport flammable, explosive, and volatile low-temperature ethylene liquids, and they represent one of the key pieces of equipment in ethylene production facilities. Due to the high technical challenges and harsh operating conditions involved, this technology has long been monopolized by foreign companies, meaning that such pumps have to be imported. There are very few manufacturers in China capable of producing such products. Apart from the technical and manufacturing challenges, whether the pump can be started successfully is one of the key indicators for assessing the reliability of this product. Under normal circumstances, even for foreign-made products, there is no record of a successful first attempt at operation; in most cases, four to five attempts are required, over a period of nearly a month or even longer. Moreover, after operation, the performance is inconsistent and failures occur frequently, posing a serious threat to the safe operation of the device. The two low-temperature ethylene pumps provided by our company started operating successfully without any issues within two days, and all performance indicators met the requirements of the plant; in fact, some of these parameters were even better than those of foreign-made products. The smoothness of their operation exceeded the owner’s expectations. In February 2017, through the joint efforts of Shenyang Industrial Pump Factory, Zhongyuan Petrochemical Co., Ltd., and Sinopec Engineering Corporation (SEI), the two low-temperature ethylene pumps developed and manufactured by Shenyang Industrial Pump Factory for Zhongyuan Petrochemical Co., Ltd. were both started successfully on their first attempt. This marked a precedent in China for low-temperature ethylene pumps to be successfully commissioned from the first try. The client gave full recognition and high praise to Shenyang Industrial Pump Factory for its excellent product quality and meticulous, thorough on-site commissioning services. The successful commissioning of the low-temperature ethylene pump (-104 degrees) indicates that Shenyang Industrial Pump Factory has reached international first-class standards in the fields of high-end product development and quality control.
