查看更多>>摘要:The author used two common methods in this industry, i. e. the "Consumption Coefficient Method" and the "Elasticity Coefficient Trend Method", to forecast the refined oil product demand in 2010. Through analyzing and comparing the two forecast results, it is projected that the demand for finished product oils in 2010 will be in the range of 220 to 240 million tons a year. In addition, out of concern about the total oil products consumption to exceed 600 million tons/year in 2020, the author puts forward suggestions and measures aimed at conservation of oil products and application of alternative fuels.

The investment in this unit is expected to reach 2.36 billion RMB, and startup of the said unit is slated for the fourth quarter of 2008. Construction of this 1.13Mt/a methanol project in addition to the already coming on stream 600 kt/a methanol unit and the 200 kt/a unit of the Mongolian Tianye Chemical Company will expand the methanol production capacity of this company to 2.0 Mt/a.

查看更多>>摘要:This article introduces the commercial application of FCC technology equipped with a gasoline auxiliary reactor in the RFCC unit at PetroChina Harbin Petrochemical Branch Company. Test results have shown the excellent outcome for commercial application of the gasoline upgrading in the auxiliary reactor to reduce the olefin content in FCC naphtha. Application of this technology can reduce the olefin content in FCC naphtha to less than 35 v%. Adjustment of the FCC operation towards more severe conditions can further reduce the olefin content in FCC naphtha to less than 20 v%, so that the FCC naphtha can meet the current standard or meet more stringent specification requirements in the future to achieve compelling economic and social benefits.
