Detailed Hydrocarbon Analysis of Refinery Naphtha Streams for Determination of Compound Group-types

Petroleum fuels are required to meet federal and state environmental regulations to mitigate their impact on the environment. There are hundreds of chemical components in spark ignition fuels, and so to make the testing and regulation manageable they are measured in categories by chemical group-type. These category group-types are based on molecular similarities that give them common performance behaviors. These tests are referred to as Detailed Hydrocarbon Analysis (DHA) which includes several test methods that measure different hydrocarbon subset or group-type categories. DHA identifies the important individual components in spark ignition fuels and other refinery light hydrocarbon process streams. Common refinery naphthas are virgin, alkylate, reformate, FCC and Coker, and finished spark ignition fuels. This technique is sometimes also referred to as PONA, PIONA or PIANO analysis since specific test methods are measuring the group-type paraffins, isoparaffins, olefins, naphthenes, aromatics and oxygenates. The DHA analysis helps optimize the production processes in addition to meet regulatory requirements. TN-2082
