| 20090184029 | Method to alter coke morphology using metal salts of aromatic sulfonic acids and/or polysulfonic acids - A method for altering coke morphology in a delayed coking process of heavy oil is provided. An effective amount of oil dispersible or oil soluble metal salts of aromatic sulfonic acids and/or polysulfonic acids is added or contacted with the resid or heavy oil at a point before or after the step of heating the heavy oil to coking temperatures. The addition of additives facilitates the formation of shot coke and inhibits the formation of sponge coke. | 07-23-2009 |
| 20090266742 | Method for Reducing Fouling of Coker Furnaces - A method for reducing furnace fouling in a delayed coking process comprising (a) supplying at least one feed to a delayed coking unit comprised of coker furnace, at least two coke drums and a coker fractionator, (b) increasing the aromaticity of the feed to produce a modified stream by combining with the feed upstream of the coker furnace at least one added stream selected from the group consisting of an aromatic gas oil, a hydrotreated aromatic gas oil and combinations thereof, (c) introducing the modified feed stream into the coker furnace, d) heating the modified feed stream to a coking temperature in the coker furnace to produce a heated modified stream, and e) transferring the heated modified stream from the coker furnace to a coke drum. | 10-29-2009 |
| 20090283447 | ELECTRO-GASIFICATION PROCESS USING PRE-TREATED PET-COKE - A method is provided for electro-gasification of pet-coke, including the steps of providing a pet-coke material; treating the pet-coke material to obtain a treated pet-coke material having an average particle size of between about 20 and about 106 μm; and exposing the treated pet-coke material to electro-gasification conditions to produce synthesis gas and/or hydrogen. Extraction of metals from the pet-coke is facilitated. | 11-19-2009 |
| 20090314685 | DELAYED COKING PROCESS WITH MODIFIED FEEDSTOCK - A process of delayed coking with modified feedstock is described maximising the volume of diesel oil and minimising the volume of coke produced by means of feedstock which comprises, in a first embodiment of the invention: the bottom product ( | 12-24-2009 |
| 20100108570 | Method for improving liquid yield in a delayed coking process - A system and method for removing oil from the surface of coke left in refinery coke drums before it is cut out is disclosed. The process does not add time to the coking cycle, nor involve the addition of major equipment. A solvent is added to the stripping steam. The solvent could be either a hydrocarbon fraction such as a coker distillate, a light gas oil or another fraction having an end point below 450° C. The solvent-enhanced stripping steam becomes a very effective oil extraction vapor when injected into the coke drum. | 05-06-2010 |
| 20130153466 | COKER INLET DESIGN TO MINIMIZE EFFECTS OF IMPINGEMENT - Coke drum assembly is provided with a vessel having a body portion defining an interior, a central axis, and having a lower portion including a sidewall, and at least one feed inlet coupled with the lower portion in fluid communication with the interior of the vessel. The at least one feed inlet is directed toward the central axis of the vessel, and angled upwardly at a feed inlet angle relative to the central axis. At a location opposite the feed inlet, the side wall of the lower portion is angled upwardly at an opposing wall angle relative to the central axis, wherein the feed inlet angle is less than or equal to the opposing wall angle. Method also is provided for delayed coking using the coke drum assembly disclosed herein. | 06-20-2013 |
| 20130199967 | COKING DRUM, SHUT-OFF VALVE FOR A COKING DRUM AND METHOD OF FEEDING RESIDUAL MATERIALS INTO A COKING DRUM - The invention relates to a coking drum, especially for petroleum coke production, which has an approximately cylindrical basic body and also at least one inlet opening and outlet opening, a shut-off valve ( | 08-08-2013 |
| 20130240408 | METHOD FOR REDUCING SILICONE ANTIFOAM USAGE IN DELAYED COKING PROCESSES - The current invention provides an improved petroleum coking process wherein the risk of silicone poisoning of units downstream of the coke drums is reduced. The method of the current invention controls the foam layer within the coke drum by injection of a silicone anti-foam agent in a highly aromatic carrier fluid such as slurry oil. | 09-19-2013 |
| 20140332445 | Pyrolysis Reactor Materials and Methods - In one aspect, the invention includes a reactor apparatus for pyrolyzing a hydrocarbon feedstock, the apparatus including: a reactor component comprising a refractory material in oxide form, the refractory material having a melting point of at least 2060° C. and which remains in oxide form when exposed to a gas having an oxygen partial pressure of 10 | 11-13-2014 |
| 20150090637 | METHOD OF PROCESSING LOW-GRADE HEAVY OIL - The present invention provides a method for processing low-grade heavy oil, comprising: providing a riser-bed reactor; preheating the low-grade heavy oil and injecting it into the riser reactor to react with solid catalyst particles at the temperature of 550-610° C.; oil-gas, after reacting with the solid catalyst particles in the riser reactor, being introduced into the fluidized bed reactor to continue to react at temperature of 440-520° C. and weight hourly space velocity of 0.5-5 h | 04-02-2015 |
