Adsorption nitrogen plant

NT-MDT Spectrum Instruments is an INTEGRA Nano IR–scattering scanning near‑field optical microscope (s-NSOM) designed for the infrared spectral range. The AFM probe is located in the focus of an optical system that directs the IR laser radiation to the sample and collects the optical response. The collected radiation is sent to the Michelson interferometer for optical analysis. The far-field component of the collected signal is suppressed by synchronous detection. The INTEGRA Nano IR system allows detecting the amplitude and phase of the near-field signal. The spatial resolution of the resulting reflection and absorption contrasts is approximately 10 nm and is determined only by the size of the tip of the probe.

A membrane nitrogen plant is a set of special equipment designed to produce nitrogen from atmospheric air by the method of membrane separation at a pressure of up to 25 bar. The production of nitrogen in this technological process is based on the principle of separation of gas mixtures in a membrane module, due to the different penetration rates of the components of the gas mixture through polymer membranes and the differential partial pressures on both sides. In the case of separation of the air mixture, oxygen has a greater permeability than nitrogen. The difficult-to-penetrate gas components (N2, CH4, CO) pass along the entire length of the generator and then come to the consumer. The output is a gas mixture with an N2 content of up to 99.9%. The membrane installation allows to obtain high-pressure production gas (nitrogen). The composition of a standard membrane nitrogen production plant: Air compressor; Dehumidifier; Main filter block, including coal column; Air receiver; Membrane generator; Production gas receiver.

The MS-1104E spectrometer is characterized by high performance and accuracy of Mössbauer measurements achieved through the use of “compressed” geometry, as well as the use of highly efficient and selective resonant scintillation detection units that improve the energy resolution of resonance absorption lines by up to 30%. The technique of software and hardware stabilization of the spectrometric path developed and used in the spectrometer allows for long-term Mossbauer measurements without manual adjustment. The method of modulation in the specified speed intervals can significantly increase the sensitivity and expressiveness of measurements and reduce the time to determine the magnitude of the effects of resonant absorption by tens of times in the study of temperature phase transitions with a low concentration of resonant elements. The electronic components of the spectrometer are developed on the basis of a modern element base using programmable logic matrices and microprocessors. Adjustable spectrometric paths and high-voltage power supplies of the PMU are integrated into detection units, modulator driver modules and multi-channel storage are made in the ISA standard and are located in the processor unit of the computer. Setting and monitoring of all parameters of the spectrometer and processing of the measured spectra is carried out from the operating windows of the control and processing programs. Since 2000, more than ten spectrometers of this type have been supplied to leading scientific organizations in Russia and neighboring countries. One of the few industrial applications of Mössbauer spectroscopy should be noted - the development and supply to the Volgodonsk NPP of certified MS-1104Em methods and spectrometer for monitoring corrosion processes in the heat exchange circuits of the VVER-1000 reactor.

A membrane nitrogen generator is a special equipment designed to produce gaseous nitrogen from atmospheric air by the method of membrane separation. The gas separation process proceeds due to the different penetration rates of the components of the gas mixture through the polymer membranes due to the differential partial pressures on both sides. During the separation of compressed air, impenetrable nitrogen passes along the entire length of the membrane module and enters the consumer, and oxygen, which has better permeability through the membrane, is discharged into the atmosphere as permeate. At the output, we get a gas mixture with a nitrogen content of up to 99.9%. The main components of the membrane generator are: membrane modules placed on a support frame-base together with auxiliary components (valves, regulators), respectively connected to each other. The generator is equipped with an automatic control system to control the parameters of the gas mixture separation process.
