Risk and Safety Analysis

This paper will elaborate on the possibilities and influencing factors for revamp and upgrade projects for sulphuric acid plants and OUTOTECs possible contribution to a successful execution of such projects. Main drivers to execute revamp project will be discussed: e.g. changing environmental requirements, increased demand for acid production, increased demand for energy production as byproduct or changes in production profile. Other aspects might target lower operating costs, better availability or longer operating periods between shutdowns. Finally, worn-out equipment must be replaced and decision must be taken either to go like-for-like or to use the chance to combine the replacement with an upgrade to more developed solutions. The paper will also cover the various aspects and influencing factors, which contribute to the decision making in a revamp project. Such aspects might be budget or schedule restrictions as well as restricted resources for labour and material at site during the execution of the project. OUTOTEC will present its portfolio of possible services covering engineering, procurement, construction, commissioning as well as operating and maintenance support, spare parts business or operator training. Depending on the project setup the split of scope and responsibilities has to be carefully chosen and agreed between the involved parties to obtain the optimum result. The presentation will provide examples of executed revamp and modernization projects of the recent past.
