Iranian Specialists Indigenize Centrifugal Compressors

Iranian researchers at a knowledge-based company succeeded in indigenizing centrifugal compressors used in the oil and gas industries.

“Centrifugal compressors are classified as dynamic compressors due to their radial thrust flow. These compressors increase the kinetic energy of the cooled gas by using rotating blades, and as a result, the pressure and temperature of the fluid also increase,” said Alireza Sadri, the managing director of the knowledge-based company.

Noting that centrifugal turbocompressors can produce a very high volume of compressed fluid, equivalent to several smaller compressors from other technologies, such as screw, he said, “These features play an effective role in optimizing energy consumption, increasing production efficiency, and decreasing costs. Also, with their high speed, they produce continuous and uniform compressed air, which prevents shocks in the consumption network.”

“These compressors are divided into two types of single-stage and multi-stage. Each of these categories can be divided into drip, pressurized and oil-free types in terms of lubrication system. The oil-free type, by using frictionless magnetic bearings, reduces mechanical wear and improves reliability and efficiency. These compressors have an energy production capacity of up to 35,000 kW and are very suitable for industries that require high pressure. In addition to having a compact and lightweight structure, the compressors are also able to work with a wide range of fluids, including helium and liquid nitrogen,” Sadri said.

Iranian Experts Produce Encapsulated Glucose to Increase Productivity of Dairy Cattle

Specialists from the University of Tehran presented a new solution to improve the nutrition and reproduction of dairy cows by producing encapsulated glucose.
