In this article we consider and discuss a problem of achieving low-static temperatures in adiabatic expansion of gas versus throttling of gas flows in case of a sudden pressure gradient, i.e. like during pressure reduction to 10 MPa in the low-temperature gas separators (LTS) and discuss calculation results obtained at transonic, sonic, and supersonic gas flow regimes with Mach number higher than 0.6. As situations of adiabatic expansion of gas due to a sudden pressure drop occur rather often in narrowing parts of the gas transport system and cause significant harm in formation of icicles and hydrates, which subsequently further narrow the flow through the narrowing nozzles and similar equipment. Furthermore, such motion causes alterations to the speed of sound registered around the narrowing nozzles, latches, control valves and such. The results obtained in the calculations and basic parameters are representative of typical work modes of jet apparatuses used in gas separators.
