The carbon-rich natural gas is defined as the natural gas contains more than 20% content of carbon dioxide. It is reported that oil and gas resources in the South China Sea account for about one-third of China's total oil and gas resources, equivalent to 12% of the world's total. More than 83% of the oil and gas resources in this region are natural gas, which generally contains 20-80% or even more than 92% of carbon dioxide (CO2). To utilize these CO2-rich nature gas in traditional industrial and residential sector, a decarbonization process is necessary, which will cause a large amount of energy consumption, methane loss and greenhouse gases (GHG) emission. In this paper, based on industrial production with annual capacity of million tons of methanol, ammonia/urea, etc., a platform technology is developed for direct, green, efficient and high-value mega-size utilization of the CO2-riched nature gas, that is the technology of CO2-riched natural gas dry reforming and hydrogen reaction. The following technologies are discussed, such as CO2-riched natural gas dry reforming integrating with Fischer-Tropsch to olefins (FTO) technology to produce high value-added linear alpha olefins (LAO) ; CO2-riched natural gas dry reforming integrating with low carbon olefin linear hydroformylation technology to produce higher carbon alcohols; direct methanol production from CO2 and hydrogen; and new cutting edge technology of light catalyzing process. In addition, simple techno-economic evaluations of two technologies mentioned above are discussed. The CO2-riched natural gas dry reforming integrates with FTO technology can achieve about 30% of internal rate return (IRR), while the low carbon olefin linear hydroformylation technology only has 2.57 recovery years when the capacity of 2-PH is 100 KTPA. Finally, based on the mega-size green and high-efficient CO2-rich natural gas direct utilization technology, a hybrid energy and chemical production system framework with good prospects is preliminarily designed. A modern industry zone with annual capacity of more than 10 million tons of CO2 converted to high value-added products is underway.

Based on the characteristics of composition and hydrotreating reactions of residue, new definitions of virtual molecular-group components about CH and CH2 are proposed here. The new reaction, hydrogenation of CH to CH2 (HDCH), can be used to represent the change of C and H with reaction conditions in residue hydrotreating. Meanwhile, by using the lumping approach, the kinetic models of HDCH, HDS, HDN, HDCCR, HDM, HDNi and HDV reactions are established. They are key components of the new kinetic model for residue hydrotreating based on chemical reaction sections. During the process of constructing the kinetic model, the goodness-to-fit (R2) between test data and model data is set as target value, and the parameters of the kinetic model can be calculated accurately. In verification test, the predict content of H, S, N, CCR, M, Ni and V obtained using the kinetic model can match well with the test data.

Taraxacum kok-saghyz (TKS) is one of the second natural rubber-bearing plants suitable for large-scale biochemical engineering development in recent years. Natural Rubber (NR) in TKS is mainly composed of cis-1,4-polyisoprene, a natural organic macromolecular compound, which is the metabolic end product of isoprenoids in plants. In this paper, a rapid and quantitative ultra-high performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS) method was established for the determination of macromolecules biosynthesis substrate (dimethylallyl pyrophosphate, DMAPP) and initiator (farnesyl pyrophosphate, FPP) in TKS. Kromasil C18 chromatographic column was used for separation, and the multi-reaction monitoring mode (MRM) of triple quadrupole mass spectrometry (TQ-MS) was used for detection. Quantification was done by external calibration method. The results showed that limit of detection (LOD) and the limit of quantitation (LOQ) of DMAPP were 2.42 μg/L and 7.26 μg/L, and the LOQ and the LOD of FPP were 1.02 μg/L and 3.05 μg/L. At the concentrations of 1-1000 μg/L, both analytes had good determination coefficients (> 0.999) of calibration curve. The recoveries of DMAPP and FPP were between 99.0% and 117.1%. In real samples detection, the contents of DMAPP and FPP in TKS samples were between 23.32~82.77 μg/L and 12.03~85.67 μg/L, respectively. Thus, this is a reliable method to quantify DMAPP and FPP in TKS.

With the increasing attention to environmental protection, it is still necessary strictly to control the oil evaporation loss from the IFRT (internal floating-roof tank) to the atmosphere. Based on the wind-tunnel experiments and the CFD numerical models and taking n-hexane for the example of oil, the effects of the WDAs (wind deviation angles) on airflow distribution, the wind speed, n-hexane vapor concentration and evaporation loss rate in the IFRT were investigated, and the mass transfer of the vapor-air was analyzed. The results are shown as follows: when the WDA is 00, the vapor concentration in the gas space above the floating deck is the lowest; when the WDA is 22.50, the evaporation rate is the largest; when the WDA is 450, the concentration is the highest, but the evaporation rate is the smallest. It is recommended to arrange the vent to the wind direction with 450 to reduce the evaporation loss.

Hydrogen management is important for refineries to improve their business efficiency. Various approaches such as pinch analysis and mathematical programming have been employed in the management of hydrogen system. However, it is not easy for site engineers to implement these technics, due to the complicated procedures. At this point, it is necessary to develop a software that implements the proposed methodologies automatically, while it is the goal of this work. The presented refinery hydrogen system optimization software (RHO) is a web based system. It is developed in the Java Web environment, where subroutines of mathematical model coded in GAMS software can be easily called. RHO could generate graphics of both the hydrogen pinch diagram and the hydrogen distribution network. Purifiers as well as the physical distances between units are considered in the optimization model. In addition, there is a special module for the calculation of membrane separation, which is important in the hydrogen network. The functions and the interfaces of the software are illustrated via practical cases. Case studies show the effectiveness of the RHO software.
