light hydrocarbon
3.The refrigeration methods are compared. Two light hydrocarbon recovery methods to different components of incondensable gas from raw oil stabilizer are developed: 1×104Nm3/d gas wave refrigeration technique and 3×104Nm3/d cryogen circulation combined with gas wave refrigeration technique.
4.his paper describes the outstanding advantages,such as low pressure drop,high flux,uniformdistribution of liquid and gas,etc. of DJ tray,which was developed by the authors in the recent twentyyears,and predicts the prospects for the applications of this tray in various high liquid-gas ratio opera-tions and light hydrocarbon separation.
5.For this reason, This text refract light from alkane hydrocarbon index and density relation set about, probe into its line sexual relations, and express with mathematics type, make the satisfactory result.
6.By using PONA analysis technology,the qualitative and quantitative analysis of the composition of monomer hydrocarbon and famlily of the cyclohexane,reactived cyclohexane and recovered cyclohexane in polyethylene unit,was made,and compared with the packed column chromatography of spinacane,so the PONA analysis technology became aneffective and accurate mean that was about to compositive analysis of light and heavy hydrocarbon in cyclohexane in polyethylene unit. ?
7.In light of low degree of prospecting and research as well as complex geologic condition for hydrocarbon accumulation, the research of hydrocarbon migration and accumulation and the exploratory direction in this area will be in further exploration.
8.With liquified petroleum gas as hydrocarbon,carbon felt as porous preform,C/C composites were fast fabricated by multi-coupling felds CVI process. C/C composites with density more than 1.7 g. cm~(-3) were obtained with lower 650℃in one cycle within 15h,and pyrocarbon microstructures were investigated with a polarized light microscope (PLM).
