Skimoil: Specialty--- Floating Oil SkimmersOil skimmers are used to remove free and floating oil from water. Oil water separators are flow thru devices to remove oil from a moving water stream. SkimOil, Inc. is a specialty design/builder that has all technologies available for skimming floating oils, fuels, fats and grease from the surface of water. All of SkimOil oil skimmers are well proven, state of the art and highly specialized systems used extensively in the steel, WWT, power plant, manufacturing and petroleum industries across the globe. Oil in water is a big part of the industrial processing world. Oil skimming for industrial purposes (except the steel industry*) and inland water spill response is generally done by one of the two following methods: 1. Selective oil skimming which exposes an oil attracting plastic or metal (i.e. belt, drum, disc, tube or rope mop) to the oil on the surface of the water. Always motor driven, this media once coated with oil, is then wiped, wrung or scraped off for transfer of oil by gravity draining or by pumping to storage. This method is highly selective and delivers relatively little water with the oil. When these selective skimmers are running in wall to wall oil, they will actually pull the oil into the skimmer, much like you could pull a carpet across a room. These skimmers must be in oil to work, and are the most efficient oil skimmers known on Earth. 2. Gravity oil skimming is done by taking advantage of the difference in specific gravity between oil and water. Most oils are lighter than and float on water. Gravity oil skimming includes adjustable standpipes, fixed overflow weirs and floating weir oil skimmers. Gravity oil skimming can also remove scum, floc, vegetation like seaweed and algae, foam and some floating junk. All gravity oil skimmers are overflow weirs. Best of all, SkimOil, Inc. can also set up gravity oil skimmers to skim below the surface. Floating weir oil skimmers (FWS) can be installed almost anywhere you have the room, hook a hose to it, put it in the water and start pumping liquid from the skimmer. These are the only skimmers in the world that can collect light sheen. FWS skimmers are true surface skimmers. These floating weir oil skimmers create a depression or low spot in the water, so whatever is on the surface will run into it. It actually allows you to drain an area from the top down, skimming whatever is on the surface. This is generally non-selective, and removes a good amount of water with the oil since the water is actually the carrier of the oil over the weir. This water can often be decanted back to source, but can cause treatment and/or storage problems if it is to be discharged. Oil Water Separators are often used. SkimOil, Inc.’s floating weir type skimmers are often used for skimming floating ash, plastic, scum, floc, duckweed, algae and water meal from water impoundments. These FWS floating weir skimmers are great for spill response---they are lightweight, easy to deploy and use, plus they have a variable recovery rate (10-400 gpm) that makes them the true utility workhorse for surface skimming from water. All of SkimOil, Inc.’s skimmers are quality made in the USA and are furnished to solve specific oil removal problems through the use of its specialty, unique and innovative technologies and equipment that can be used for oil removal under almost any conditions. Every industrial skimming job is different and requires a unique approach. SkimOil does oil skimmers every day ----and has found that each successful industrial skimming job requires application specific knowledge and specialized equipment options. SkimOil, Inc.’s skimmers can be furnished as complete systems, complete with pumps and hoses. Expert oil skimming consulting and application engineering help is available.

China's oil product imports of Current Situation and Countermeasures
In recent years, as economic globalization and rapid economic development, China's oil consumption has been second only to the United States, ranking second in the world. The same time, a serious shortage of domestic oil production, import dependency growing. According to statistics, in 2009 China's net imports of 219 million tons of oil, and the apparent consumption of 408 million tons, the import dependence of 50% the first time, petroleum products imported into the bulk of the most important resource commodities. At present, Shandong ports of petroleum products has become an important base for the import, the import trade of the author based on the new features ports, combined with the practical front-line inspection, analysis of the current quality of imported petroleum products, the existing problems, and puts forward countermeasures and suggestions in order to boost imports of oil products a benign growth.
With crude oil imports and rising international oil prices, crude oil imports shortweight become increasingly prominent, primarily in the following aspects: First, lack of loading port shipments. Some shippers for their own interests, in accordance with the exemption within five thousandths or less of the weight of international practice in the volume control device. Second, the measurement in different ways. Weight capacity of the cabin to take the current weight of the way, when the ports of loading weight adverse sea conditions affect the readings of weight staff. Third, uninstall the volume difference. Unloaded in two hours when the Hong Kong Port and more often a shortage of one port discharge. Fourth, do not fully uninstall. A few species because of their physical properties caused by the oil tank wall oil and bilge oil left serious, ships can not fully emptied.
In addition, imports of fuel oil quality can not be ignored. Analysis of the following reasons: First, the relative complexity of fuel oil components, quality volatile. Second, domestic and international fuel standards are not uniform. The current international fuel oil major component of the 180CST and 380CST and M40, M100 and M300, while the domestic petrochemical only were classified on the fuel oil, fuel oil into 1 ~ 7. Third, the standard does not apply. International fuel oil are mainly used for fuel, fuel oil imports are currently mainly used for domestic processing, the main purpose and scope of application of inconsistent standards. Fourth, the domestic standard is lagging behind. National standards are currently widely used SH/T0356-1996 ASTMD396-92 reference standard is not updated and amended.
In this, the author recommends that companies take effective measures to avoid trade risk: First import enterprises should be stipulated in the contract to the port of discharge issued by quality inspection and quarantine institutions and weight results as the basis for settlement to avoid the shipper loading port the occurrence of short weight; 2 clear in the contract of enterprise measurement method, the best to shore tank discharge measurement transfer, the ability of enterprises can use flow meters to measure the transfer pipeline; Third, goods assembled in Hong Kong occurred in the proposed company sent in ships, real-time monitoring discharge rate and avoid a multi-port discharge less than a Hong Kong; Fourth, a few physical characteristics with sticky, wall seriously detrimental to the oil discharge operation, it is suggested companies specified in the contract to the port of discharge tank quantity settlement.
Recommended inspection and quarantine authorities strictly regulate the inspection and supervision work on the operation of a unified standard. Currently there is no national standard imported oil, the Industry Standard and other uniform inspection standards should be developed as soon as possible the import of petroleum and petroleum products inspection regulations, harmonization of port inspection and monitoring procedures. Strengthen the technical training, particularly to increase the intensity of training testing of fuel oil imports. Strengthening port inspection and quarantine authorities of other exchanges between, when the two-Kong branch of imported crude oil unloading the present situation, should be timely and relevant port inspection and quarantine departments to Jishu 交流 and communication, unified standards and testing methods Fang Zhi Chu Xian Jiao testing results Big difference.
