This article is mainly based on the characteristics of marine environment islands and coastal seas current corrosion problems storage tanks as well their main locations, analyse reasons for formation consider potential safety hazards, so to propose several effective tank protection methods, which has important positive significance long-term development oil tanks.

Experiments were conducted to study the performance of circular and square tank surface aerators on the oxygen transfer coefficient and to a limited extent on power requirements. All the tanks are geometrically similar except for their shapes. They consist of a rotor of diameter, D, fixed with six flat blades rotating with a speed, N, in pure waters of viscosity, υ, at room temperature. A simul...

sloshing is a well-known phenomenon in liquid storage tanks subjected to base or body motions. in recent years the use of multiple vertical baffles for reducing the sloshing effects in tanks subjected to earthquake has not been taken into consideration so much. on the other hand, although some of the existing computer programs are capable to model sloshing phenomenon with acceptable accuracy, t...

This work addresses the large-scale crude oil scheduling problem of China’s SINOPEC Maoming refinery importing various types of crude oil from two terminals via long-distance pipelines. A hierarchical decomposition approach is employed to construct a two-stage MILP model of the practical refinery operations. In the upper level model, storage and charging tanks are aggregated to determine the in...

A methodology for simulating the dynamics of large industrial fires in the outdoor environment is presented. The large eddy simulation techniques developed by the authors and their collaborators are used to simulate a fire on top of a large oil storage tank adjacent to several neighboring tanks. The governing equations are modified to account for the stratification of the ambient atmosphere. A ...

Abstract Liquefied natural gas (LNG), ethylene, ethane, propane, and other clean energy are often stored in a cryogenically frozen state on large scale. As the core equipment of cryogenic storage tanks, if different media stored, there certain differences design tanks. Although specifications differ little, is lack systematic research. This paper compares material, process, structure, construct...

The RoboCrane is a revolutionary concept in crane automation. The RoboCrane, based on the Stewart platform parallel link manipulator design, consists of cables as the parallel links and winches as the actuators. The result is a work platform that can maneuver tools and/or manipulators with full six degree-of-freedom control. EMMA, a serpentine manipulator, is currently being developed for sever...

In this color mixing machine we use three tanks which are of Red, Blue and Yellow. The three tanks consist of level sensor and fitted with hydraulic line. The hydraulic line consist of solenoid valve.The tank consists of color Steiner of Red, Blue and Yellow. The Steiner flows from hydraulic line into the mixing tank through solenoid valve. The solenoid valve is a digital output device that is ...

The paper addresses control related design issues for neutralization plants. Mainly for control reasons, the neutralization is usually performed in several steps (mixing tanks) with gradual change in the concentration. The aim is to give recommendations for issues like tank sizes and number of tanks. Assuming strong acids and bases, we derive linearized relationships from the disturbance variab...

elevated tanks are important structures in storing vital products, such as petroleum products for cities and industrial facilities, as well as water storage. these structures have various types and are constructed in a way that a greater portion of their weight is concentrated at an elevation much about the base. damage to these structures during strong ground motions may lead to fire or other ...
