“…The results showed the maximum profit is attainable at 135°C for Maya crude oil. Mahdi et al experienced effect of emulsifier concentration, temperature, fresh water rate, settling time and mixing time on the dehydration efficiency in the crude oil desalting [5]. The results showed that salt removal efficiency approaches to 93.28% at the optimal condition.…”

“…Therefore, it is necessary to increase or decrease the weight of floating ball for purpose that the density of floating ball is within a reasonable limit [10,11]. Since the weight of floating ball has a great effect on drainage device, it should be watched closely at the change of oil quality and match the weight of floating ball in real applications.…”

Aqueous crude oil often contains large amounts of produced water and heavy sediment, which seriously threats the safety of crude oil storage and transportation. Therefore, the proper design of crude oil tank drainage device is prerequisite for efficient purification of aqueous crude oil. In this work, the composition and physicochemical properties of crude oil samples were tested under the actual conditions encountered. Based on these data, an appropriate crude oil tank drainage device was developed using the principle of floating ball and multiphase flow. In addition, the flow field characteristics in the device were simulated and the contours and streamtraces of velocity magnitude at different nine moments were obtained. Meanwhile, the improvement of flow field characteristics after the addition of grids in crude oil tank drainage device was validated. These findings provide insights into the development of effective selection methods and serve as important references for oil-water separation process.

“…The water produced along with oil consists of salts whose concentration varies between 150,000 and 220,000 ppm. For most real cases, the salt content of the crude oil is composed of salt dissolved in tiny drops of water, which are distributed in the oil (Smith and Arnold, 1992;Arnold and Stewart, 1998;Mahdi et al, 2008). Thus, properties of the water phase (e.g., viscosity, density and solubility) might be altered significantly, leading to considerable effects on volume and movement of the fluids in the underground formation and surface facilities (Gibson and Loeffler, 1941;Mohameda et al, 2003).…”

The salt elimination from produced crude oil is an important stage in oilfield processing and it is considered as a compulsory requirement in the oil industry. In most cases, salt is found a dissolved component in the brine phase in contact with oil. Different compositions of various salts might exist in the brine; however, sodium chloride (NaCl) has the highest fraction in the solution. The water existing in the crude oil is seen as very small drops dispersed in the bulk of oil. In the current study, a simple predictive strategy for density determination of aqueous salty solution in crude oil as a function of salinity (in vol% of sodium chloride concentration), temperature, and pressure is proposed through combination of an Arrhenius-type asymptotic exponential function and the relationship introduced by Spivey et al. (2004). The developed method predicts the amount of salt in the crude oil for temperatures up to 373 K, sodium chloride concentrations up to 250,000 ppm (25% by volume), and maximum pressure of 200 MPa, upon availability of the required input data. Estimations obtained from the proposed approach are found to be in very good agreement with the reported data in the literature so that the absolute error percentage varies in the range of 0.003-1.681%. The technique introduced in this research appears to provide reliable value for the oil engineers to attain a fast estimation of the salt content in the crude oil at various operating conditions without conducting laboratory tests. It is believed that the approach would be user-friendly without complicated computations for chemical and petroleum engineers and researchers. It can be also combined with existing thermodynamic software packages, resulting in an accurate and fast predictive model for practical applications.
