AVD6 unit revamp-study

AVD6 is in production since 1971 with daily processing of crude oil 6500 tons. It has operated since that with a few mode and equipment changes and is used for production of primary products (intermediate products) for production of fuels.

Current processing of crude oil is 8500 t/day. As we can see, the processing has several times increased since start-up. Mode changes in processing also need changes and modifications ( modernization ) of old equipments, which because of the capacity are insufficient for current processing of crude oil.
On the basis of capacity (increased processing compared to designed conditions) and technical conditions of the equipments (large wear), and on the basis of the new requirements for products, the require of revamp resulted. The main goal of this project is list and short description of some problems and their possible solution for revamp the AVD6. This work does not contain detail proposals and does not describe procedure of implementation, only hypothetically and theoretically shows possible solutions, which are need further explaining in more detail, resp. chemical-engineering projects and estimations.
