Abstract Getting correct estimates for Volatile Organic Compounds (VOCs) and greenhouse gases (GHGs) from water storage tanks is not only important for maintaining emission compliance for state and national regulatory authorities, but also crucial in designing the capital-intensive systems for economic use of methane and other Natural Gas Liquid (NGL) gasses. This paper highlights the significance of gas liberated from produced water tanks in the fields. The paper presents a laboratory method to estimate such emissions from produced-water storage tanks by virtue of the in-situ water getting depressurized and releasing VOCs, and other emission gasses such as Hydrogen Sulfide (H2S) and Carbon Dioxide (CO2). Further, the paper provides qualitative and quantitative assessment of the gas liberated from produced-water by analyzing the gas liberated from produced-water from gas-condensate reservoir wells from the Marcellus region.

Water Tanks

In this study, the dynamic behavior of elevated water tanks is investigated by performing a comprehensive parametric study on conical elevated tanks using the finite element technique. Through this study, a wide range of tank parameters and geometries typically found in practice is considered. To perform this parametric study, a parametric model capable of building any finite element models of a three-dimensional conical elevated tank with varying parameters is developed. As a result of this parametric study, pressure distribution graphs corresponding to both impulsive and convective hydrodynamic pressures can be generated by carrying out spectral analysis. These pressure graphs can be utilized simply in design applications for liquid-filled conical elevated tanks. The accuracy of the proposed pressure graphs is verified by comparing these results with those calculated using the previously verified finite element time-history analysis and also the “current practice”.

The Impact

The fatigue limit and lifetime of epoxy-based coatings may be affected by various factors, especially the environmental effects. This paper evaluates the impact of air, potable water media, and pollution gases (CO2, H2S, and SO2) on the fatigue performance of two types of epoxy-based coatings (polyamine and polyamide epoxy-based coatings) used as lining for potable water storage tanks. The fatigue test apparatus is assembled in the laboratory and utilized for testing. Different factors are discussed, including absorption, adsorption, and the reaction of environmental gasses with polyamine and polyamide coating surfaces. The influence of porosity on the epoxy-based coatings is experimentally determined, and its effects on fatigue limit and fatigue life are discussed in detail. As a result, the coatings were applied to improve the fatigue resistance of stainless steel. The fatigue limits of both types of coatings tested in potable water are lower than the value obtained when tested in air or gas environments. The fatigue limit of polyamine coating is greater than the polyamide coating. The microscopic inspection indicated a different mechanism for initiating fatigue crack, and the test environments are affected by the nature of the fracture surface.

Supply Water

Water tank is a water storage structured built for long term use. These tanks were utilized for various uses like distribution of water, firefighting, agriculture, food industry, paper mills etc. It comes in handy when there is an intermittent supply of water or scarcity of water. Materials like concrete, pvc Galvanized Iron, fibre is used to manufacture tanks. Water is pumped through pipe by using pumps from a source. For distribution purpose water can be distributed either gravity or pump to reach individual with desired pressure and velocity. Volume is calculated based upon population and their usage and demand. Water demand varies hour to hour. For a continues supply water tanks are best suited. To meet water demand by public water tanks are to be constructed. Design and analysis are similar for any liquid present in water tank but is should be crack free to avoid leakage
