<p>The apparatus consists of modular stages (A, B, C) arranged in series, each stage including a main chamber 2 and a nozzle opening 5. In practice, a fluid passing through the opening S is 5 subject to a pressure drop as it enters a main chamber of a subsequent stage in the series. This multi-stage pressure drop avoids a sharp drop in temperature, as would occur if the total pressure drop was achieved in one stage, that may cause hydrates to form in an oil/gas pipeline.</p> |
