摘要： Gas separation processes are provided for separating dehydrogenation reaction products from a raw gas stream to recover hydrocarbons, specifically olefins, such as propylene and iso-butene, as well as unreacted feedstock. The processes employ a sequence of partial condensation steps, interspersed with membrane separation steps to raise the hydrocarbon dewpoint of the uncondensed gas, thereby avoiding the use of low-temperature or cryogenic conditions.

摘要： A process for treating an effluent gas stream arising from a manufacturing operation that produces an olefin or a non-polymeric olefin derivative. The process involves cooling and condensing the effluent gas stream, which comprises an olefin, a paraffin, and a third gas, to produce a liquid condensate and an uncondensed (residual) gas stream. Both streams are then passed through membrane separation steps. The membrane separation of the uncondensed gas stream results in an olefin-enriched stream and an olefin-depleted stream. The olefin-enriched stream is recirculated within the process prior to the condensation step. The membrane separation of the condensate also results in an olefin-enriched stream, which may be recycled for use within the manufacturing operation, and an olefin-depleted stream, which may be purged from the process.

摘要： A process for recovering unreacted olefin in a polyolefin manufacturing process comprising the treatment of a purge bin vent gas. The process involves cooling and condensing the vent gas (purge stream), which contains at least an olefin, a paraffin, and nitrogen, to produce a liquid condensate and an uncondensed (residual) gas stream. Both streams are then passed through membrane separation steps. The membrane separation of the uncondensed gas stream results in a residue stream containing mostly nitrogen and/or paraffin and a permeate stream enriched in either C2+ hydrocarbons or olefin, depending on the type of separation. The permeate from this step is recirculated within the process prior to the condensation step. The membrane separation of the condensate results in a residue stream containing paraffin and a permeate stream enriched in olefin, which may be recycled to the polymerization reactor.

摘要： A method for countervailing clock skew between a first clock signal and a second clock signal in a core logic circuit. The second clock signal is sampled based on the first clock signal in a sampling cycle to obtain a sampling result. When the sampling result indicates a non-compliant pattern, the phase of at least one of the first clock signal and the second clock signal is adjusted. Desirably, the core logic circuit keeps on working with the current first and second clock signals while continuing the sampling procedure of the second clock signal based on the first clock signal when the sampling result indicates a compliant pattern.
摘要翻译：一种用于在核心逻辑电路中抵消第一时钟信号和第二时钟信号之间的时钟偏移的方法。基于采样周期中的第一时钟信号对第二时钟信号进行采样以获得采样结果。当采样结果指示不兼容模式时，调整第一时钟信号和第二时钟信号中的至少一个的相位。理想地，当采样结果指示顺从模式时，核心逻辑电路继续使用当前的第一和第二时钟信号，同时基于第一时钟信号继续第二时钟信号的采样过程。
