Title: David A. Hadfield: Innovator in Oil Spill Recovery Technologies
Introduction
David A. Hadfield is a notable inventor based in Houston, Texas, recognized for his contributions to oil spill recovery technologies. With a total of three patents to his name, Hadfield has made significant strides in developing innovative solutions for environmental challenges.
Latest Patents
One of Hadfield's latest patents is focused on hydrocyclones for oil spill cleanup, specifically designed to have a controlled split ratio. This oil spill recovery system includes a first hydrocyclone separator and, optionally, a second hydrocyclone separator located on a floating vessel. The system is engineered to recover spilled oil from a body of water effectively. The first hydrocyclone separator separates the recovered fluid into a first underflow stream containing oily water and a first overflow stream that contains substantially all of the oil and water emulsion. The oily water underflow stream is then directed to a second hydrocyclone separator, which further separates it into a second underflow stream returned to the sea as clean water and a second overflow stream. The first overflow stream is stored in the on-board ship's storage, while the second overflow stream may be stored or recycled for further separation. Another patent by Hadfield involves hydrocyclones for oil spill cleanup with an oil slug monitor, enhancing the efficiency of the recovery process.
