Abstract
A start-up method for contacting a feed stream with fluidized catalyst is disclosed. The start-up method comprises reacting a feed stream over a catalyst to produce a gas stream and spent catalyst. The gas stream is separated from the spent catalyst. The separated gas stream is passed to a compressor. The operating condition associated with the compressor is measured. Based on the measured operating condition associated with the compressor, one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream is provided to the compressor to meet a predetermined operating condition associated with the compressor.
Claims17
A start-up method for contacting a feed stream with fluidized catalyst comprising:
- reacting a feed stream over a catalyst to produce a gas stream and spent catalyst;
- separating said gas stream from said spent catalyst;
- passing the gas stream to a compressor;
- measuring an operating condition associated with the compressor;
- providing one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream to the compressor based the measured operating condition associated with the compressor to meet a predetermined operating condition associated with the compressor, and
- regulating a flow rate of one or both of the supplemental hydrocarbon stream and the supplemental hydrogen gas stream to the compressor by sending a command configured to cause an adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream, wherein the adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream causes an adjustment to a composition of the gas stream entering the compressor.
A start-up method for contacting a feed stream with fluidized catalyst comprising:
- reacting a feed over a catalyst to produce a gas stream and spent catalyst;
- separating said gas stream from said spent catalyst;
- passing the gas stream to a compressor;
- providing one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream to the compressor based on a measured operating condition from one or more sensors associated with the compressor to meet a predetermined operating condition associated with the compressor;
- and
- regulating a flow rate of one or both of the supplemental hydrocarbon stream and the supplemental hydrogen gas stream to the compressor by a data analysis platform, the data analysis platform comprises one or more processors, memory, and a communication interface in communication with the one or more sensors associated with the compressor, wherein the flow rate of one or both of the supplemental hydrocarbon stream and the supplemental hydrogen gas stream to the compressor is regulated by sending a command configured to cause an adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream, wherein the adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream causes an adjustment to a composition of the gas stream entering the compressor.

- separating said gas stream from said spent catalyst;
- passing the gas stream to a compressor;
- providing one or both of a supplemental hydrocarbon stream and a supplemental hydrogen gas stream to the compressor based on a measured operating condition associated with the compressor comprising hydraulic pressure, an inlet gas temperature, a compressor rotation speed, or an average molecular weight of the gas stream at a suction side of the compressor;
- and
- regulating a flow rate of one or both of the supplemental hydrocarbon stream and the supplemental hydrogen gas stream to the compressor to meet a predetermined operating condition of the compressor associated with a steady-state operation, wherein the flow rate of one or both of the supplemental hydrocarbon stream and the supplemental hydrogen gas stream to the compressor is regulated by sending a command configured to cause an adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream, wherein the adjustment to one or more valves associated with the supplemental hydrocarbon stream and the supplemental hydrogen gas stream causes an adjustment to a composition of the gas stream entering the compressor.
