Pilot Test of No-Hydrogen Mild Cracking with Molecular Sieve of Crude Oil

The development of a new technology for lowering or reducing the pour point and viscosity of crude oil from small test to pilot test,named no-hydrogen mild cracking with molecular sieve improvement technology of crude oil,is introduced in this paper. The results show that the test results from the pilot test which is 1000 times scaled up from the small test are in approximate accordance with those from the small test, which verifies that the technology is feasible for scaling-up in technique and can be further scaled up to industrial test and production. Improved crude oil can be used in existing crude oil transportation to lower oil delivery temperature and to reduce fuel consumption,in particular,to solve transportation problems of low-flow rate pipelines. Also,some features of with-molecular sieve improvement technology of crude oil,such as,simple process,easy operation,less costs;high rates of reduction of pour point an viscosity of crude oil, stable properties of improved crude oil;and potential economics,are analyzed in this paper. The technology has better suitability to feedstock crude oils and the size of industrial unit and application conditions for it can both be changed according to requirements.
