| Abstract It is well known that the ca-pacity of crude distillation units in any refinery reflects the capac-ity of the refinery itself, and that is because we consider these units as the first stage and all other units such as vacuum distil-lation, hydrotreating, reforming, catalytic cracking, and others de-pend on them. So we devoted our effort to keep these units work with high performance and effi-ciency. The purpose of this paper is to develop crude distillation units in Daura refiner, rise their perfor-mance level and overcome weak points wherever detected. Our work here conducted by si-mulation program (HYSYS) and consists of two stages: Before changing operating conditions, and after changing operating conditions. Each one will be dis-cussed separately later. This work shows that these old units contain a lot of mistakes because they are working since 1954. These mistakes are concen-trated in miss operation due to absence of daily close monitoring to the operation conditions and product specifications related to gap and overlap conditions, and this really affects badly on recti-fication efficiency. | ||
