Abstract: FIELD: chemical industry. SUBSTANCE: the invention presents a method of utilization of heat in the nitric acid production process. The method provides for utilization of heat of nitrose and caudal gases in the installations of a nitric acid production. The method of utilization of heat emitted in the nitric acid production process under pressure includes compression of the air, oxidation of ammonia by the air at the temperature of 850-930 o C, cooling of the received nitrous gases with production of water vapor, an absorption of nitrogen oxides, expansion of the caudal gases heated up to 500-800 o C, in the gas turbine from 0.5-0.8 MPa up to pressure close to atmospheric one, cooling of the extended gases from 270-430 o C down to l50-180 o  C before their discharge in the atmosphere. At that the nitrous gases are cooled from 850-930 o C down to 280-350 o C with the heat transfer through a wall, producing at that some water vapor with pressure up to 6 MPa and temperature up to 450 o C, and the extended caudal gases are cooled with heating the whole amount or a part of u a deaerated feedwater under pressure of up to 6 MPa up to boiling with a partial evaporation, and a steam- and-water mixture is merged with the steam-and-water mixture produces at cooling of nitrous gases within a uniform contour. As a version it is possible that a part of the feedwater is heated up under pressure of up to 6 Mpa by the oxygenated nitrous gases and-or by the hot compressed air with consequent combination of the obtained steam-and-water mixture with the steam-and-water mixtures produced at utilization of heat of nitrose and caudal gases. EFFECT: the method allows to utilize with maximum efficiency the heat obtained in the nitric acid production process, to generate the high-grade steam used as a source of heat and to produce a mechanical power for air and nitrose gases compression, and steam surplus for electric power production. 2cl, 2 dwg, 2 ex

Abstract: FIELD: measuring engineering. 
     SUBSTANCE: two pulse pickups of angular position are mounted on the shaft. In rotation of unloaded shaft the signals from the pickups are synchronized in phase of torsional oscillations to be measured. When the shaft is loaded, the shifts of signal pulses of torsional oscillations are determined in two spaced sections of the shaft. The difference between the shifts determine the angular deformations caused by the oscillations of the torque in the drive of machine. 
     EFFECT: enhanced accuracy and reliability of measurements.

Abstract: Изобретение относится к процессу синтеза аммиака, в частности к усовершенствованию способа очистки синтез-газа, добавляемого в каталитический реактор для замещения прореагировавшего синтез-газа. Способ синтеза аммиака включает сжатие синтез-газа, содержащего водород и азот в многоступенчатом центробежном компрессоре. На первой ступени этого компрессора синтез-газ сжимают до давления, составляющего от приблизительно 800 до 900 фунтов на квадратный дюйм -(56-63)·10 5 Па, отводят с этой ступени и охлаждают, а также обезвоживают путем контакта с жидким аммиаком в дегидраторе, затем охлажденный и обезвоженный синтез-газ возвращают в компрессор и вводят на его вторую ступень. Установка для проведения этого процесса включает центробежный компрессор, снабженный выпуском синтез-газа, соединяющий выпуск с первой ступени компрессора с впуском синтез-газа в дегидратор, а также промежуточный впуск синтез-газа, соединяющий гидравлической связью впуск второй ступени компрессора с выпуском синтез-газа из дегидратора. Благодаря промежуточному охлаждению и обезвоживанию скорость компрессора снижается, а за счет благоприятного воздействия дегидратора на последние две ступени указанного компрессора достигается также значительная экономия потребляемой мощности. Дополнительная экономия мощности осуществляется за счет того, что в замкнутом контуре синтеза снижается потребность в холоде. 2 н. и 11 з.п. ф-лы, 1 ил.
