US Patent:

6352639, Mar 5, 2002
Filed:

Dec 13, 2000
Appl. No.:

09/735779
Inventors:

Jackson I. Ito - Sacramento CA
Leonard Schoenman - Citrus Heights CA
Dean C. Draemel - Kingwood TX
Teh C. Ho - Bridgewater NJ
George A. Swan - Baton Rouge LA
Assignee:

Exxon Research and Engineering Company - Annandale NJ
International Classification:

C10G 1100
US Classification:

208113, 208153, 208157, 239 8
Abstract:

An atomizing gas, such as steam, and a hot fluid comprising a hot liquid to be atomized, are passed under pressure, through separate fluid conduits in a heat exchange means, in which the hot liquid heats the steam to a superheat temperature, by indirect heat exchange. The superheated steam is then injected into the hot fluid, which comprises a two-phase fluid comprising steam and the hot liquid, subsequent to the superheated steam injection. The two-phase fluid is passed through an atomizing means, such as an orifice, into a lower pressure atomizing zone, which causes the steam to expand and atomize the liquid into a spray of liquid droplets. The two-phase fluid is formed before or as a consequence of the superheated steam injection and is preferably steam-continuous when passed through the atomizing means. This process is useful for atomizing a hot feed oil for a fluid cat cracking (FCC) process.

US Patent:

6783662, Aug 31, 2004
Filed:

Oct 17, 2002
Appl. No.:

10/273932
Inventors:

Dean C. Draemel - Kingwood TX
Nicholas C. Nahas - Chatham NJ
Teh C. Ho - Bridgewater NJ
Assignee:

ExxonMobil Research and Engineering Company - Annandale NJ
International Classification:

C10G 3510
US Classification:

208158, 208157, 208113, 208126, 208127
Abstract:

A cavitation enhanced atomizing process comprises forming a flowing solution of the liquid to be atomized and a lower boiling cavitating liquid. This flowing solution is then contacted with a pressure reducing means, at a temperature below the bubble point of the cavitating liquid in the solution, to produce cavitation bubbles. These bubbles comprise cavitation liquid vapor and the bubble nucleation produces a two-phase fluid of the bubbles and liquid solution. The two-phase fluid is passed downstream into and through an atomizing means, such as an orifice, and into a lower pressure atomizing zone, in which the bubbles vaporize to form a spray of liquid droplets. The nucleated bubbles also grow in size as the so-formed two-phase fluid passes downstream to and through the atomizing means.

International Classification:

G01N 25/20
US Classification:

436147, 208 18, 208 19, 208 48 R
Abstract:

Methods for determining the fouling propensity of a hydrocarbon stream and for reducing fouling are provided. In one method, the fouling propensity of a hydrocarbon stream is determined by obtaining a parameter value indicative of the fouling propensity at no less than two different temperatures, and an activation energy of fouling by the hydrocarbon stream is derived therefrom. In another method, the thus obtained parameter value at no less than two different temperatures and the activation energy are used to select proper heating fluids and operating temperature and to determine whether to add an antifoulant to the hydrocarbon stream to reduce fouling at a given temperature.
