Design and Fabrication of Sea Oil Separator

Oil is one of the precious crude and being used in many routine applications of human life. During the operating of crude oil, the transportation of crude oil requires the adoption of safety measures in port terminals. At sea accidents are further serious cause of oil pouring and cause of pollution. It is not easy to determine the amount of oil spilled into sea every year but according to estimates, it is expected to be around 4 million tons in the whole planet and 600.000 tones only for Mediterranean. Research and technological advancements in enhanced oil recovery (EOR) had been growing at a high rate over the past 10 years due to growing concern that all the ‗easy oil' has been exploited and result of high oil prices, which increased R&D appetite and investment into enhanced oil recovery (EOR). In this Project, we are designing a prototype of a device which can be used to recover this spilled oil.

Design and Operation of Small to Medium scale Oil-spill Cleaning Units

Oil pollution, which may be either from marine accidents or from standard ship operations, is dangerous to the marine environment, with possible long term effects. The degree of damage depends on the amount of oil spilled, the geographical and environmental conditions as well as nature of the marine life in the area. The cost of cleaning up and the damage caused could go into billions of Euros. There are various methods which have been used to combat and minimise the oil spill damage, and the reaction time to the oil spill is an extremely important factor in determining the amount of oil that can be collected before spreading to shorelines, where the cleaning costs are significantly higher.

ANALYSIS ON OIL REMOVING MECHANISM FROM WATER

Worldwide statistics on oil spills show that the incidence of major oil spills has significantly fallen over the last three decades. However, environmental awareness and sensitivity to the impact of oil spills have grown at an even quicker pace over the same period.The prime focus of oil spill response activities is in prevention and planning. This is achieved through well-designed equipment, good maintenance and operating procedures, sound training techniques and a high degree of awareness and concern at all levels by employees and management. Despite best prevention practices an incident may occur. In the event of an incident the objective of the oil spill response is to assure that actions are efficient and compatible with the balanced environmental, social, and economic needs of the community. The response strategy includes all viable techniques to reduce damage from a spill. No oil spill response option would be ruled out or limited in advance.There is no doubt, therefore, that continued investment in preventive measures and emergency response capabilities is justified. A number of advanced response mechanisms are available for controlling oil spills and minimizing their impacts on human health and the environment. The key to effectively combating spills is careful selection and proper use of the equipment and materials best suited to the type of oil and the conditions at the spill site. Most spill response equipment and materials are greatly affected by such factors as conditions at sea, water currents and wind. Gauging the performance of oil spill response equipment has long been of interest for government regulators, oil spill responders and the oil industry. 1. INDRODUCTION The considerable increase of oil exploration and transport in Arctic waters will increase the risk of an oil spill occurring in cold and ice-infested waters. Currently, mechanical oil spill recovery in cold climates is inefficient largely due to the fact that the equipment available to oil spill responders was not designed to collect very viscous oils and oil-ice mixtures. The presence of ice crystals in oil emulsions affects the adhesion processes between an oil slick and the surface of an oleophilic skimmer and prevents oil from being efficiently recovered. Oil spill responders have used weir type skimmers and large vacuum hoses to suck in oil-ice mixture, resulting in a significant amount of free water in the recovered product, reducing oil spill recovery efficiency and creating a discharge problem. Oleophilic skimmers are based on the adhesion of oil to the rotating skimmer surface. The rotating surface lifts the oil out of the water to an oil removal device

Onboard Flotation System for Spilled Oil Clean up at Sea

2017

Oil spill response is a top priority for the oil and gas industry and instrumental for obtaining a license to operate. It is a demanding task in any environment, but Arctic regions present particularly difficult challenges. The U.S. Department of Energy’s (DOE) National Energy Technology Laboratory (NETL) has performed research taking unique flotation skills and equipment previously used for coal preparation and repurposing them to investigate oil separation under Arctic conditions. Commercial flotation equipment has been used to ensure that all device specifications meet industrial standards and are ready for commercialization. The study involved experiments to measure oil separation using a flotation process at simulated Arctic conditions. NETL has successfully demonstrated the feasibility of using a flotation process for rapid separation of crude oil under Arctic and Gulf of Mexico (GOM) conditions. Oil separation efficiency with different surfactants, temperature, and ice condit...

Monitoring The Usage of Marine Fuel Oil Aboard Ketapang Gilimanuk Ship

Proceeding of the Electrical Engineering Computer Science and Informatics

The development of the shipping industry in Indonesia has continued to increase over the past 10 years due to the sabotage principle. This development can be seen from the increasing number of national vessels. The number of national vessels becomes wider from 6,041 units in 2005 to 24,046 units in 2016. The more number of vessels owned makes monitoring the operational performance of the vessel difficult because each ship has different travel routes. This research made tools that can monitor the performance of ships especially the use of MFO aboard the ship from a distance. The sensors used to measure the volume of MFO in the tank on board are HC-SR04 ultrasonic sensors and potentiometer pendulum sensors. The data from the sensor was processed by Arduino Uno microcontroller. This study would compare the performance of ultrasonic sensors and potentiometer pendulum sensors mounted on MFO oil premises. The study was conducted by measuring the position of the ship horizontally, right and left tilted with a slope level of 30 degrees and 45 degrees. The result of this research is that the potentiometer pendulum sensor was better when MFO surface condition was flat with the average of error sensor 1.60%, while HC-SR04 ultrasonic sensor has an average of error for 2.87%. However, on the skewed surface conditions of MFO, the usage of HC-SR04 ultrasonic sensors was better with average of error for 3.21%, while the potentiometer pendulum sensor had an average of error for 8.66%.

Oil Spill Control: an Automatic Pollutant Sensing and Dispelling Approach

The Nigerian Oil and Gas industry is one of the leading and sensitive sectors of the Nigerian economy which contributes about 35% of gross domestic product and petroleum export revenue represents over 90% of total exports revenue. This makes the industry important to the economic stability of Nigeria. Oil and Gas exploration takes place in the south-western region in Nigeria, which is mostly enclosed with sea and swamp where hydrocarbon is conventionally found. The Nigerian oil industry is mainly operated and controlled by expatriates with locals restricted to support field strength. In the course of operation, oil spillage is often encountered leading to loss of resources, human, animal and material. In order to remedy this bad occurrence which has damaging effect on equipment, contamination of the sea with accompany threat to sea creatures, human beings as well as high cost of clean ups, an “Automatic Oil Spill Dispelling Device Model” is presented as part of efforts put in place to mitigate oil spillage in the Nigerian Oil and Gas industry.

DESIGN AND FABRICATION OF OIL SEPARATING DEVICE WITH WATER PURIFIER

In metal working industries, various water-based emulsions industries such as sugar factory, food processing, chemical etc are used as coolant to enhance productivity. This emulsion is mixture of water and different types of cutting oils in a specific ratio. The processed water at sugar factory has created pollution. The sugar factory is requiring huge amount of water daily and the processed water has to be wasted to the river. The processed water contains low pH value which causes the land salty which cannot be used for agriculture and this is dangerous. The oil and grease contents in water effects on the land as well as on human beings. Due to chemicals present in water, the water lives are on the edge of destroying. To avoid all these problems, Endless belt type oil skimmers are manufactured. These skimmers consist of geared motor that continuously rotates a Belt made up of special material which allows the oil particles stick to it .these oil particles are then scrapped by scrapper and collected in separate oil collecting bin. The objectives are to separate the oil from water and purify the water from dirt particles.To reuse the water, High efficiency and ability to meet environmental regulations.Belt-type skimmers use an endless belt of stainless steel, elastomer or poly medium, which is lowered into the tank or vessel to be skimmed. The belt passes though resilient wiper blades where the oil is removed from both sides of the medium.

Mechanical Cleaning of Oil Spills in Seawater Using Circular Conduits

Energy Sources, 2005

Treatment of the crude oil pollution in seawater has attracted global attention during the last two decades. This study was undertaken using circular conduits as a mechanical means to clean oil spills in seawater under different conditions of temperature, oil gravity, shaking frequency, conduit diameter, and initial thickness of oil layer. An experimental model was designed and built to achieve the study. It consists of shaking water bath (to represent sea waves) fitted with temperature controller and glass tubes of different inside diameters of 0.3 cm, 0.5 cm, and 0.7 cm. Three crude oils of different oil gravity of 35 • API, 38 • API, and 47 • API were investigated under different shaking frequencies of 20, 40, and 60 stroke/minute with different tube diameters. The results proved that application of mechanical cleaning of oil spills using circular conduits is a practical technique. The cleaning of black oil spills is more efficient than one of volatile oil. Furthermore, the results indicated that the increase of shaking frequency and/or water temperature provide(s) faster cleaning of oil spills while temperature increase recovers the maximum oil.
