Title: Method of reducing pressure of natural gas
Inventor: BORISKIN V V
IPC: F17D1/04
Filed: 2000-04-19
Granted: 2002-03-10
Abstract: FIELD: methods of preheating gas due to use of energy potential of compressed gas and ambient heat; gas-distributing stations. SUBSTANCE: part of high-pressure natural gas is cooled due to recuperative heat exchange with flow of low-pressure gas before supplying it to standard regulators of gas-distributing station; then, gas is admitted to vortex tube where it is divided into two flows at different temperature (cold and hot flows) in the course of reducing pressure. Cold flow is heated due to ambient heat in one of two change-over atmospheric heat exchangers and is combined with low-pressure gas flow after gas-distributing station. Then, it is preheated due to recuperative heat exchange with high-pressure gas and evacuated to consumer's main combining with hot flow. EFFECT: possibility of making natural gas pressure reducing process close to isothermic process and obtaining positive temperature of gas after gas-distributing stations, thus excluding freezing and swelling of ground along head sections of gas lines. 1 dwg

Abstract: FIELD: metallurgy. SUBSTANCE: invention particularly refers to processes of production of cast iron articles with compact and ball-shaped graphite with determination of coefficients from cooling curves and with control over content of structure modifying alloys in melt. Four calibrations based on cooling curves registered in center of vessel for specimens are carried out to establish quantity of modifying alloy added into melt to produce cast iron with compact and ball-shaped graphite. Cooling curves are then analyzed to determine control factors γ,φ,ρ в  and k. Three independent determinations of quantity of structure modifying addition agents are executed and most accurate result is found. Invention is also related to gear for control over production of cast iron that includes sampler, computer system to collect data and aid to inject structure modifying addition agent into molten cast iron. Sampler includes representative specimen of molten cast iron which is subjected to thermal analysis during which measurements of curves " temperature-time " are entered into computer and displayed as cooling curves. Computer computes required quantity of injected structure modifying addition agent and automatically activates aid to inject structure modifying addition agent. As result melt is provided with proper quantity of these addition agents. EFFECT: capability to predict microstructure of cast iron, to evaluate substantially large range of curves " temperature-time " and to choose required quantity of modifying addition agent injected into melt to produce cast iron with compact and ball-shaped graphite. 12 cl, 6 dwg
