Review on the Trend for Development of World＇s Petroleum Refining Industry

This article introduces the situation related with the increasingly deteriorating crude quality, the demand for cleaner transportation fuels and clean production processes that the world＇s petroleum refining industry is faced with. This article also suggests that the trend for future development of global refining industry is focused on the economy of scale for the refineries and the oil processing units, the refining structure readjustment, integration of the oil refining and chemical production and formation of oil refining bases. The oil refining industry will uninterruptedly rectify its industry allocation and processing unit configuration and strive for the reduction of production cost through technical progress and management innovations to reduce the production cost, boost the profitability and sharpen the market competitive edge.     

Overview on Routes for Development of China''''s Petroleum Refining Technology

China has formed a complete and packaged system of domestic petroleum refining industry. Till 2020 the demand for petroleum products in China will record a sharp growth. However, China is currently confronted with a shortage of oil resources, unsatisfactory quality of petroleum products, a widening gap between demand and supply of steam cracking feedstocks, and a stern situation in environmental protection. In this context the petroleum refiners of China, while taking into account the actual conditions, should seek for the way of deep processing to produce transportation fuels and chemical feedstocks that can hardly be replaced by other energy forms, continue to bring into full play FCC process as core process for making finished oil products, speed up the development of hydrocracking to achieve integration between refining and chemical production, adopt measures that can combine feedstock pre-treatment, novel FCC technologies and after-treatment of products to improve the quality of finished products, as well as realize the recycling of wastewater and control over air pollution caused by SOx to accelerate the development of petroleum processing industry in China.

Recovery and Characterization of Petroleum Residues Through the Molecular Distillation Process

Molecular distillation process is an efficient way to separate complex residues to obtain improvement and a more complete characterization of crude oils. It presents advantages such as to generate distillation products that can be experimentally characterized, and the operation conditions of this process generate distillate cuts with an atmospheric equivalent boiling point (AEBP) above 650°C without risks of thermal degradation. The aim of this work is to carry out the separation of two vacuum residues (VR) within the process temperature range from 550 to 670°C, using the Brazilian Molecular Distillation equipment. As a result, five distillate cuts and five residues from molecular distillation processing were generated. The molecular distillation (MD) technique provided a gain in distillate yield of about 10% over the conventional methods. The efficiency of the technique was verified through the vapor pressure osmometry experiments and the extension of true boiling point (TBP) curves of petroleum. The extended TBP curves by the molecular distillation process demonstrated that this alternative method is appropriate to extend the TBP curves to temperatures above those of the conventional methods.
