The general object of this invention is to provide an improved process for sweetening and desulfurizing sulfur-containing crude oil streams. Heating the sulfur-containing crude oil stream to an elevated temperature for an extended period of time while stirring and bubbling an inert gas into the crude accelerates the removal of sulfur containing gases from the crude oil stream. Furthermore, the addition of a polyalkylamine to the stirred crude oil can also greatly assist in the expulsion of sulfur containing gases. After processing under these conditions, the hydrogen sulfide producing capacity of the crude oil is reduced significantly, thus making the crude safer for transportation and handling by reducing the health and environmental risks.

Sweetening of sour crudes

A method of reducing the viscosity of a heavy oil flowing through a pipe is disclosed. The method includes mixing heavy oil, water and an effective amount of C,to C,alcohol so as to reduce the viscosity by at least 20% that of the heavy oil. The amount of water present in the heavy oil should be less than about 50% vol. and preferably from about 1% vol. to about 10% vol. The alcohol preferably should be a primary linear alcohol and more preferably is a C,to C,primary linear alcohol which may be selected from 1-propanol, 1-butanol, 1-pentanol, 1-hexanol, 1-heptanol or combinations thereof The concentration of alcohol should be less that 10% by weight of the mixture. The mixture may further include a polymeric drag reducing agent in a concentration from about 1 to about 10,000 ppm.

A residual oil feedstock comprises carbon residue measured according to ASTM D-4530. The feedstock is admixed with water/steam in an amount of 10 wt % to 30 wt % and optionally a hydrogen donor, such as methane and/or gas oil derived from recycle. The resulting admixture is subjected to delayed coking reaction conditions. The process yields hydrocarbon liquids in an increased amount. Coke make and gas make are thereby reduced.

In a process for oxidation of methacrolein to methacrylic acid the carbon monoxide present in the recycle gas can be selectively oxidized to carbon dioxide with substantially no oxidation of the methacrolein content. A preferred catalyst for such an oxidation is a crystalline alumino silicate having pores of about 4-5 angstroms diameter and containing within the pores at least one metal or compound of the noble metal group, particularly platinum.
