  • Patent number: 9139781
    Abstract: The morphology of petroleum cokes produced by the delayed coking of feeds produced from extra-heavy crude sources such as those from the Venezuela Orinoco Heavy Oil Belt can be controlled to produce a less dense coke which is less likely to inflame in the coke pit or in subsequent handling. An aqueous solution of an alkali metal or alkaline earth metal carbonate salt when added to a feed of this type which would normally produce a dense coke product is effective to produce a quenchable coke product of lower density and higher porosity, usually in compact, granular form permitting it to be readily discharged from the drum.

The process includes the steps of injecting a first quench fluid downstream of a primary transfer line exchanger to quench the process effluent comprising olefins, separating in a first separation vessel a cracked product and a first byproduct stream comprising tar from the quenched effluent, directing the separated cracked product to a water quench tower system and quenching the separated cracked product with a second quench fluid to produce a cracked gas effluent for recovery and a second byproduct stream comprising tar. An apparatus for carrying out such process is also provided.

  • Patent number: 7578929
    Abstract: A process for feeding or cracking heavy hydrocarbon feedstock containing non-volatile hydrocarbons comprising: heating the heavy hydrocarbon feedstock, mixing the heavy hydrocarbon feedstock with a fluid and/or a primary dilution steam stream to form a mixture, flashing the mixture to form a vapor phase and a liquid phase, and varying the amount of the fluid and/or the primary dilution steam stream mixed with the heavy hydrocarbon feedstock in accordance with at least one selected operating parameter of the process, such as the temperature of the flash stream before entering the flash drum.

  • Patent number: 7553878
    Abstract: The present invention provides a feedstock composition for increasing the efficiency of atomization in hydrocarbon processing that includes a water-in-hydrocarbon oil emulsion including a non-ionic surfactant capable of stabilizing the emulsion and having a hydrophilic-lipophilic balance of greater than about 12. The emulsion includes water droplets of about 5 to about 10 microns in diameter, the droplets being dispersed substantially uniformly in the hydrocarbon oil phase. These surfactants are capable of stabilizing the water-in-hydrocarbon oil emulsion under relevant temperature and pressure conditions for hydrocarbon processing. The inventive feedstock composition provides a metastable water-in-oil emulsion where expanding water vapor explodes under spray conditions where the system pressure is released, demolishing a larger oil droplet and producing smaller oil droplets.

  • Publication number: 20090014355
    Abstract: Metal additives to hydrocarbon feed streams give improved hydrocarbon liquid yield during thermal cracking thereof. Suitable additives include metal overbases and metal dispersions and the metals suitable include, but are not necessarily limited to, magnesium, calcium, aluminum, zinc, silicon, barium, cerium, and strontium overbases and dispersions. Particularly useful metals include magnesium alone or magnesium together with calcium, barium, strontium, boron, zinc, silicon, cerium, titanium, zirconium, chromium, molybdenum, tungsten, and/or platinum. In one non-limiting embodiment, no added hydrogen is employed. Coker feedstocks are a particular hydrocarbon feed stream to which the method can be advantageously applied, but the technique may be used on any hydrocarbon feed that is thermally cracked.
