Title The Process Design of the Fractionation Section of an Aromatics Complex with a 600 kt/a Capacity.
Abstract
Para-xylene is an important chemical raw material mainly used for the production of terephthalic acid and polyester fibers. The design will mainly focus on the fractionation section of an aromatics complex, which can pide raw meterials into mixed xylenes, ortho-xylene, C9 and C10 aromatics by distillation separation method. The major equipments is xylene tower, ortho-xylene tower and heavy aromatics tower and some accessory equipments. The major design tools are AspenPlus, Aspen Exchanger Sizing and Rating software. To make the fractionation section in accordance with the production goal, the technical process, producing equipment and plant layout are designed in detail.
Keywords Aromatics Complex; Distillation; AspenPlus
