Basd on the panel data of China's 36 industrial sectors in 2000-2009, this paper analyzes the energy relationship of different sectors by grey relational theory. Results show that China's industry is strongly dependent on fossil fuels, and China needs optimize its industrial energy consumption structure. To do that, this paper finds out the industrial sub-sectors which should reduce fossil energy...
The possibility of obtaining modified petroleum resin, whose structure is determined by means of 1H-NMR spectroscopy and GLC, by copolymerization of various fractions of liquid products of pyrolysis and butyl methacrylate under the influence of cationic catalysts is shown. The yield of modified resins decreases in the following pattern: C9 > DF > CF. The number of aromatic units reduces as their...
We investigated the performance of DH-A series of flooding system, which consists of hydrophobic association polymer (HAP) (Provided by Sichuan Guangya Technology Co., Ltd.), Alkali (NaOH) and Surfactant (heavy alkylbenzene sulfonate ), under the reservoir conditions in Daqing. The detailed composition of ASP system included 0.08 ∼ 0.16 (wt)% of HAP, 0.025–0.3 (wt)% of surfactant, and 0.4 ∼ 1.2 (wt)%...
The objective management system for oil production plant is built first; Then an energy evaluation system on base of energy technical efficiency, economic efficiency of energy and energy efficiency is constructed in multiple levels; Finally, a AHP-fuzzy comprehensive evaluation model is setup to evaluate the situation of energy-saving for oil production plant qualitatively.
Chemical oxygen demand (COD) has been the crucially problematic parameters in refinery wastewater treatment. This study was conducted to investigate COD removal in refinery wastewater with Fenton process. The effects of pH value, H2O2 dosage, the mole ratio of Fe2+ to H2O2, oxidation time and oxidation temperature on COD removal were discussed. The results showed that COD removal efficiency first...
The chemical components and using performances indexes can be tested for different aging degree heavy traffic paving asphalt by different aging time through the rotary-thin-film-oven test. According to the test data, the influence of aging time on asphalt chemical composition and using performances are analyzed, and the influence of asphalt chemical composition on using performance is analyzed too...
Marine oil spill will cause persistent damage to environment, marine ecology, economy and society. Started from the hazards of marine oil spill, behaviors of spilled oil at sea environment, including spreading, advection and horizontal diffusion, vertical dispersion, evaporation, dissolution, emulsification etc. were overviewed, and the main factors influence these behaviors were analyzed. Thereafter,...
The volatile oils of Arundo donax Linn (giant reed) were extracted by two methods, one was Water-steam distillation, the other was petroleum extraction and then fractionated with some chemical reagent. Components of the volatile oils were analyzed and identified by gas chromatograph-mass spectrometry (GC-MS), and the allelopathic effect of the volatile oils were also explored by bioassay of Microcystin...
According to present research on venturi scrubber in china and abroad, on the basis of synthesizing the relevant mechanism of venturi and cyclone scrubber, a new kind of venturi-swirler-combined scrubber was developed. This venturi-swirler-combined scrubber is composed of shuttle-typed components and swirler. These shuttle-typed components were assembled to comprise a honeycomb-typed structure gas...
Computer aided techniques form an efficient approach to solve chemical product design problems such as the design of blended liquid products (chemical blending). In chemical blending, one tries to find the best candidate, which satisfies the product targets defined in terms of desired product attributes (properties). The systematic computer-aided technique first establishes the search space, and then...
We choose Australia, Germany, France, Britain, Japan, South Korea, Russia and the United States as Chinese major trade partners based on the characteristics of imports, and calculate the sector carbon consumption coefficients by input-output tables of eight selected nations, and measure the amount of embodied carbon imported from these eight countries according to the amounts of imports. The results...
Chemical oxygen demand (COD) have been the crucially problematic parameters in refinery wastewater treatment. This study was conducted to investigate the COD removal effectiveness in refinery wastewater with the activated pretreatment petroleum coke (APPC) prepared by combination of chemical activation with KOH solution and physical activation with calcination at lower temperatures. Adsorption experiments...
We demonstrate a novel method to create cylindrical multiphase interfaces within microfluidics. Such interfaces are formed and maintained solely by surface tension at physical boundaries within the channels for simpler fabrication, easier control, and better robustness. This structure promises a versatile enabling technology cylindrical interfaces between air and aqueous phases, between aqueous and...
A novel soft sensor modeling method based on kernel partial least squares (kernel PLS, KPLS) was proposed. Kernel PLS is a promising regression method for tackling nonlinear problems because it can efficiently compute regression coefficients in high-dimensional feature space by means of nonlinear kernel function. Application results to the real data in a fluid catalytic cracking unit (FCCU) process...
A pilot-scale low emission boiler plant which consists of a multi-fuel boiler and a plasma-chemical hybrid NOx removal system was investigated. This plant can achieve carbon neutrality because the multi-fuel boiler uses waste vegetable oil as one of fuels. The plasma-chemical hybrid NOx removal system has two processes; one is NO oxidation by ozone produced from plasma ozonizers, and the other is...
This paper researches tankers risk issues by detentions and deficiencies database of port state control in Europe and the North Atlantic region, Asia and Pacific region, a comparative analysis of tanker risks with other types of ship was carried out and also the risks on oil tankers, chemical tankers and liquefied gas carriers were studied, it was found that the risks of tankers by Port State Control...
Based on describing current situation, this paper firstly analyzes the inside condition and the outside environment on logistic industry by the method of SWOT at the facing harbor gather's District in QinHuangDao. Then it determines the strategy and specific task in the near future and in the long-range view. After that, it designs logistic system and plans function in logistic garden, and designs...
