Foam Suppression by Acoustic Means in the Slow Coking of Petroleum Waste

An acoustic method is proposed for foam suppression in the slow coking of petroleum residues. In this approach, pulsed gas motion and a high-intensity acoustic field are created at the point of foam formation. That does not compromise the sterility of the final product.

Description
Summary:An acoustic method is proposed for foam suppression in the slow coking of petroleum residues. In this approach, pulsed gas motion and a high-intensity acoustic field are created at the point of foam formation. That does not compromise the sterility of the final product. The theoretical principles for formation of an acoustic field whose parameters are in resonance with the acoustic characteristics of the foam are outlined. Laboratory tests of foam suppression on a cold model show that forced disintegration of foam is possible in an acoustic field of intensity up to 120 dB. Experiments on a hot model of the slow coking of petroleum residues indicate the feasibility of foam disintegration without direct contact.
