WebJan 1, 2004 · Ethylene has a critical absolute pressure of about 50 bar and a critical temperature of about 10 C14 C. Thus, a high pressure pipeline operates in the supercritical region (dense-phase) and a low pressure one in the gas region and, therefore, under normal operating conditions, both pipelines are operating in a single phase mode. http://vle-calc.com/phase_diagram.html
