Effect of Operating Conditions on Sulfur and Metal Content of Basrah Crude Oil
Main Article Content
Abstract
In the present work, Basrah crude oil, atmospheric distillate of 305-623 K boiling range, vacuum distillate of 623-823 K boiling range, and wide petroleum distillate of boiling range 305-823 K are hydrotreated in trickle bed reactor using Cobalt- Molybdenum alumina as a catalyst. Hydrotreating temperatures are 598-648K, 598- 673K, 648-673K and 648K respectively while LHSV are 0.7-2 hr-1, 1 hr-1, 0.7-2 hr-1 respectively. The operating pressure and H2/Oil ratio for all experiments are kept constant at 3 Mpa and 300 liter/liter. The results show that Sulphur and metal content decreased with increasing temperature and decreasing LHSV. Vacuum residue of boiling range above 823K is mixed with hydrotreated atmospheric distillate, vacuum distillate and with the hydrotreated wide petroleum distillate. The temperature for hydrotreating the mixed sample is 648K and LHSV is 1 hr-1. It was found that hydrotreating crude oil is the best choice since it gives the highest removal of sulphur, vanadium and cobalt removal..
