A method of removing sulphur from sour oil by nano catalyst is a novel method. ZnO nano catalyst of 45 nm in diameter is used to treat the sour oil. Two types of heavy oil with density of 29.6 and 29.7 API are sweetened catalytically. So, the different operating conditionswhich effect on the sweetening process of crude oil is investigated in this paper. Results show 70 C and 1.2 atm are the optimum temperature and pressure respectively when ZnO is applied as nano catalyst.Also, the optimumdesigned parameters for diameter and height of bed are 6 cmand 10 cm respectively. Investigations show the efficiency of proposed process is very high. So, tests approve the sweetening process of sour oil which can be replaced conventional process.
