What are the marine resources with industrial mining value that cannot be mined? Oil and gas resources, according to the 1995 estimate of the world's proven offshore oil reserves of 37.9 billion tonsReserves of natural gas are 39 trillion cubic meters.According to incomplete statistics,The reserves of oil and gas resources in the seabed account for about 1/3 of the global oil and gas reserves.Expected in this century,Offshore oil and gas development will extend from the shallow continental shelf to the sea area in kilometers of water depth.Most of the world's offshore oil exists on the continental shelf.According to estimates,The continental shelf covers an area of about 30 million square kilometers worldwide,It accounts for 8% of the world's oceans.About the reserves of offshore oil,Due to the limitation of exploration data and calculation methods,The conclusions reached are also different.An estimate by the French Petroleum Research Agency is that the global
How to determine the flow rate of the multi-media filter backwashing pump? 1. the backwashing strength of anthracite is 10 L/m2 * s, quartz sand is 15 L/m2 * s, and 12L/m2 * s is taken in multiple media.2. multiply the counter-washing strength q by the filter area of the equipment to get the counter-washing flow. the counter-washing head is generally> 15mH2O. Considering the pipe resistance and pressure loss, it is recommended to choose a 25 m head pump.The strength of the reverse wash is 10L/m2 * s, which is expressed by q. The backwashing flow is equal to the backwashing strength q multiplied by the filter area of the equipment, so that the pump flow can be obtained. 1. multi-media filters use one or more filter media to pass water with high turbidity through granular or non-granular materials of a certain thickness at a certain pressure, in order to effectively remove suspended impurities and clarify the water, the commonly used filter materials include quartz sand, anthracite coal, manganese sand, etc.,
