Optimum Feed Stream Candidates in Iran for Producing Petroleum Coke

Calcined Petroleum Coke (CPC) is used mainly as the main part of the anodes in the Aluminium industries. The current required capacity of green petroleum coke for the Aluminium industries in Iran is approximately about 225000 ton/year. For producing CPC, green coke from Delayed Coking (DC) unit should be calcinated. In DC unit, mainly Vacuum Bottom (VB) of the petroleum refineries is thermally cracked and produces green coke as well as lighter hydrocarbon cuts. Although a considerable amount of VB is produced in Iranian refineries, all the required CPC currently is imported and there is no operating DC unit in Iran. However, the previously performed feasibility studies show that installing a new DC unit is highly profitable.In the current work, the available resources for the feed stream of delayed coking unit have been investigated and the optimum one is selected by comparing the candidates in different criteria like feed specifications, quantity of feed, distance from the Aluminium production plants and also from the transportation ways. At the end, VBs of Abadan and Bandar-Abbas refineries have been selected as the optimum feed resources for the new DC unit in Iran
