Abstract

A method for upgrading the viscoelastic properties of a heavy oil by altering its elastic modulus. An effective amount of one or more elastic modulus lowering agents are used, wherein preferred elastic modulus lowering agents include mineral and organic acids and bases, preferably strong bases, such as hydroxides of metals selected from the alkali and alkaline-earth metals.

Claims (12)

1. A method for improving the flow properties of a heavy oil feedstock by lowering its elastic modulus, which method comprises:
treating the feedstock with an effective amount of one or more elastic modulus lowering agent selected from acids, bases, and porphyrins.
2. A delayed coking process comprising:
a) heating a petroleum resid, which is essentially a solid at room temperature, in a first heating zone, to a temperature below coking temperatures for conversion into a pumpable liquid;

b) conducting said heated resid to a second heating zone wherein the heated resid is heated to an effective coking temperature;
c) conducting said heated resid from said second heating zone to a coking zone wherein vapor products are collected overhead and coke is formed; and d) introducing into said resid or heated resid at least one elastic modulus lowering agents that are effective for lowering the elastic modulus of the resid, wherein said at least one elastic modulus lowering agent is introduced into said vacuum resid at a point upstream of the first heating zone, upstream of the second heating zone, or both.
3. The method of claim 2 wherein the elastic modulus lowering agent is selected from acids, bases, and porphyrins.
4. The method of any preceding claim wherein the elastic modulus lowering agent is at least one mineral acid selected from sulfuric acid, hydrochloric acid and perchloric acid.
5. The method of any preceding claim wherein the acid is selected from sulfuric acid and hydrochloric acid.
6. The method of any preceding claim wherein the acid is an organic acid selected from para-toluene sulfonic, alkyl toluene sulfonic acids, mono di-and trialkkyl phosphoric acids, organic mono or di carboxylic acids, formic, C3 to organic carboxylic acids, succinic acid, low molecular weight petroleum naphthenic acid, and mixtures thereof.
7. The method of any preceding claim wherein the acid is para-toluene sulfonic acid.
8. The method of any preceding claim wherein the elastic modulus lowering agent is as least one metallo-porphyrin selected from nickel and/or vanadium porphyrin.
9. The method of any preceding claim wherein the elastic modulus lowering agent is at least one hydroxide of a metal selected from the alkali metals and/or alkaline earth metals.
10. The method of any preceding claim wherein the hydroxide is of one or more metals selected from sodium, potassium, calcium and magnesium.
11. The method of any preceding claim wherein the hydroxide is of a metal selected from sodium and/or potassium.
12. The method of any preceding claim wherein the elastic modulus lowering agent is used in combination with an effective amount of steam.
