摘要： Controlling the shutdown of a polyethylene reactor system that includes a secondary compressor, a reactor, a high pressure let down valve (HPLDV), a high-pressure separator, and a high-pressure recycle gas system is provided. After a partial or complete shutdown of secondary compressor, HPLDV opens to a pre-set open position until the reactor pressure reduces to either a pre-set reduced pressure limit or a until the slope of the reactor gas density to reactor pressure exceeds 0.15. The HPLDV controls the pressure to a pressure set point.

摘要： An ethylene polymerization system is provided with a quench system and that cools the product mixture entering the separation system with a reduced load on the first compressor of the system. The system includes first and second compressors, a high pressure reactor; a high pressure let down valve through which the product mixture from the high pressure reactor flows, and a separation system that separates gas from the product mixture. The quench system includes a pump having a suction inlet that receives all or substantially all of the low pressure flow of monomer from the first compressor. The system provides quenching of the product stream while allowing the first compressor to be operated at a discharge pressure lower than the suction pressure of the second compressor, thereby conserving energy.

摘要： Systems and methods for separating particles from fluids are provided. The system comprises a vessel with at least two fluid inlets and a fluid outlet wherein one fluid inlet is positioned higher in the vessel than the other fluid inlet. The fluid inlets may be connected to a polymerization reactor and each fluid inlet may be configured to deliver fluid to the vessel from a different zone of the polymerization reactor. During shut-down of a polymerization reactor, reaction mixture is discharged to a separation system where polymer particles are removed from the mixture prior to being released into the atmosphere.
