چکیده مقاله:
In this study a novel process configuration for recovery ofhydrocarbon liquids from natural gas is proposed by applyingdemethanizer and deethanizer column. The requiredrefrigeration in this configuration is obtained by a selfrefrigerationsystem. High performance of the multi- streamheat exchangers, high recovery levels of the hydrocarbonliquids and low required compression power (in the internalrefrigeration section) and reduce the number of compressorsare the most important characteristic of the proposedconfiguration. Elimination of propane which serves asrefrigerant for industrial application such as cooling feed gasand refrigerant of deethanaizer condenser is one of the mostimportant features of this new configuration. Effect of themixed self-refrigerant flow rate and pressure on theperformance of the process is discussed. For such processesthe optimum number of multi-stream heat exchangers isthree. One of the main goals of the present study is to achieveintegrated process which energy lost is minimized andreducing number of instruments is obtained. By using themethod of this process configuration, recoveries of propaneand heavier components in excess of 98% are readilyachievable.
