Abstract
A method of controlling the supply and allocation of hydrogen gas in a hydrogen system of a refinery integrated with olefins and aromatics plants to convert crude oil into petrochemicals. The method includes one or more supply sources that provide hydrogen at individual rates, purities, pressures and costs, multiple consumption sites that consume hydrogen at individual rates, purities and pressures and an interconnecting hydrogen distribution network. The method further includes the integration of hydrogen consuming process units with hydrogen producing process units in which hydrogen recovered from the effluents from the hydrogen consuming process units and hydrogen recovered from the hydrogen producing process units are re-used in the hydrogen consuming process units.
