By applying multivariable model predictive control (MPC) technology, the control performance of the gasoline debutanizer of fluid catalytic cracking unit can be improved.
The polymerised product (mainly diisobutylene ) can be hydrogenated to be used as gasoline blending agent replacing MTBE, or separated as fine chemical feedstock.
Comparison experiments of water mist with polycomponent water mist,and the test on polycomponent water mist's extinguishing efficiency against ethanol and ethanol motor spirit fire were done.
This paper researches into enhanced heat transfer of condensation of splitting gas of waste plastics and R113 on the general smooth tubes,the screw tubes and the aculei finned tubes.
In a testing of petrolic engine, about 70% to 80% of nonmethane hydrocarbon is emitted into atmosphere without catalysis conversion in theoment of coldstart, so that serious pollution is produced.
This paper introduces the light gaso line etherify technology,brings fo rward the project of building the light gasoline etherify device on th e catalyst cracking cell in the refin ery plant.
