Gasoline working capacity

Gasoline working capacity (GWC) also shows a strong relationship with the pore volume in the mesopores. Similar to BWC, GWC is a measure of adsorption capacity in which actual gasoline vapors are used as the adsorbate. The relationship between the BWC and GWC is shown in Fig. 12. The data shows a strong relationship between the BWC and GWC. The relationship would be expected since both the BWC and GWC have excellent linear correlations with the pore volume in the small mesopores.

The capacity of CO2 to vaporize hydrocarbons is much greater than that of natural gas. It has been shown that CO2 vaporizes hydrocarbons primarily in the gasoline and gasoil range. This capacity of CO2 to extract l drocarbons is the primary reason for the use of CO2 as an oil recovery agent. It is also the reason CO2 requires lower miscibility pressures than those required by natural gas. The presence of other diluent gases such as N2, methane, or flue gas with the CO2 will raise the miscibility pressure. The multiple-contact mechanism works nearly the same with a diluent gas added to the CO2 as it does for pure CO2. Frequently an application of the CO2 process in the field will tolerate higher miscibility pressures than what pure CO2 would require. If this is the case, the operator can dilute the CO2 with other available gas, which will raise the miscibility pressure but also reduce the CO2 requirements. 

Gaoqiao, an affiliate of Sinopec, is one of the major petrochemical producers in China. The company owns 75 production units and affiliates staffed by 11 500 personnel and has the ability to produce over 200 products, including gasoline, jet fuel, diesel fuel, lube oil, paraffin wax, synthetic rubber, organic chemicals, synthetic plastics, as well as fine chemical products and so on. The principal production output comes mainly from a refinery of 11.3 millions tonnes per year crude oil processing capacity, and four petrochemical works. The company is one of the major synthetic rubber producers in China. The company s...
