With the growing demand for LNG, Zhuhai LNG terminal project plans to construct a large LNG storage tank group. In order to ensure its safety, the rationality of layout design is analyzed respectively from storage tank fire separation and tank farm quantitative risk analysis.According to NFPA 59A-2009 standard, using PHAST software to simulate accident to determine storage tank separation distance, it is considered that the current tank spacing should be further adjusted according to scope of accident; DNV SAFETI software is applied to conduct quantitative risk analysis for tank top pool fire and pipeline leakage jet fire, and receives personal and social risk chart for tank farm, it is thought that tank layout planning is feasible though compare with risk standard, also can take safety measures to make risk level as low as possible considering factors of costs and benefits. © Copyright (2013) By AIChE.

The atmospheric particulate matter in China has formed with characteristic of compounding pollution. The fine particulate matter PM2.5 has complex sources. Through an integrated analysis on concentration characteristics and source apportionment results of PM2.5 in China, the regular pattern is found. The source apportionment results have shown that the main sources of PM2.5 in China are as follows: the burning of coal, the motor vehicle exhaust, dust, secondary particles, the burning of biomass, sea salt particles, etc. In addition, the analytical techniques for analyzing the sources of PM2.5 based on the chemical composition, particular indexes and the chemistry-statistics methods are summarized, which is helpful to propose more measures to reduce PM2.5 emission from the very beginning.

Atmospheric and vacuum distillation unit is one of the largest energy-consuming units in refineries. Its energy consumption accounts for 25% to 30% of total energy consumption. The path of energy saving is pointed out through analyzing the energy consumption level in China. In order to offer a useful reference to refinery enterprises, a few typical energy saving measures are summarized.

Through the probe into a certain petrochemical enterprise and its ambient atmospheric particle samples, the temporal and spatial distribution characteristics of the particles of different sizes were discussed. Besides, the concentration relationship among several kinds of particles was also analyzed. Combined with the Pearson correlation analysis and factor analysis of atmospheric particles, the petrochemical enterprise was considered as an important source. The concentration distribution of particles demonstrated prominent differences in period (heating period and non-heating period) and location (distance from the petrochemical enterprise) as well as the meteorological conditions (dominant wind direction). The Pearson correlation coefficients among particles and fine particle proportion around the petrochemical enterprise were both high, which indicated that the source of the particles might be the petrochemical enterprise. Through the Principal component analysis and factor analysis of atmospheric particulate matter around the petrochemical enterprise, the conclusion was made that these pollutants mainly came from wastewater treatment plant, aromatic hydrocarbon equipment and the fugitive emission sources in the petrochemical enterprise.
