Patent number: 5486345Abstract: An improved oxygen-enhanced Claus process for the recovery of sulphur from an acid gas comprising hydrogen sulphide as a furnace in which a part of the hydrogen sulphide content of the acid gas is burned to form sulphur dioxide. The sulphur dioxide then reacts with residual hydrogen sulphide to form sulphur vapor which is condensed out of the resulting gas mixture. One part of the residual gas mixture is then subjected to catalytic stages to bring the reaction between the hydrogen sulphide and sulphur dioxide close to completion. The improvement resides in sending a second part of the gas mixture to an incinerator to convert all its hydrogen sulphide content to sulphur dioxide. After removal of water, the sulphur dioxide is returned to the furnace.Type: GrantFiled: August 19, 1994Date of Patent: January 23, 1996Assignee: The BOC Group plcInventor: Richard W. Watson

Patent number: 5468458Abstract: A part of the hydrogen sulphide content of a feed gas stream comprising hydrogen sulphide is burned by a burner that fires into a furnace. The combustion is supported by a stream of oxygen or oxygen-enriched air. Resulting sulphur dioxide reacts with residual hydrogen sulphide in the furnace to form sulphur vapor. Sulphur is condensed out of the resulting gas mixture in a sulphur condenser. At least part of the sulphur-free gas mixture flows through a reactor in which its sulphur dioxide content is reduced to hydrogen sulphide. Water vapor is removed from the resulting gas stream in a water condenser. At least part of the gas stream now essentially free of water vapor is recycled to the furnace. A purge stream is taken either from immediately downstream of the sulphur condenser or from intermediate the water condenser and the furnace, or from the furnace and, if desired, subjected to further treatment to remove sulphur-containing gases therefrom.Type: GrantFiled: April 1, 1993Date of Patent: November 21, 1995Assignee: The BOC Group plcInventor: Richard W.

Patent number: 5352433Abstract: A hydrogen sulphide containing feed gas stream (typically including at least 70% by volume of hydrogen sulphide) is divided into a minor stream and a major stream. The minor stream is burnt in a first combustion region to form sulphur dioxide and water vapor. The resulting gas mixture is cooled in a heat exchanger and is employed in a second combustion region in which a portion of the hydrogen sulphide content of the major stream is burnt to form sulphur dioxide and water vapor. Reaction between the sulphur dioxide and remaining hydrogen sulphide takes place in a thermal reaction region to form sulphur vapor and water vapor. The proportions of sulphur burnt in the respective combustion regions and are chosen such that about one-third of the total hydrogen sulphide content of the feed gas stream is burnt to sulphur dioxide in these regions.Type: GrantFiled: March 2, 1987Date of Patent: October 4, 1994Assignee: The BOC Group plcInventor: Richard W. Watson

Patent number: 5294428Abstract: A feed gas stream containing at least 60% by volume of hydrogen sulphide is burnt in a first combustion region to form water vapor and sulphur dioxide. Oxygen is employed to support combustion is the region. Thermal reaction then takes place in a thermal reaction region between hydrogen sulphide and sulphur dioxide to form sulphur vapor and water vapor. The resulting gas mixture is then cooled and sulphur vapor is extracted in a condenser. The gas mixture then passes into a second combustion region in which a further portion of the hydrogen sulphide is burnt in the presence of oxygen to form further sulphur dioxide and to adjust the mole ratio of hydrogen sulphide to sulphur dioxide to about 2:1. Further reaction between hydrogen sulphide and sulphur dioxide may be conducted in a further thermal reaction region and in catalytic reactors with further sulphur extraction in further condensers.Type: GrantFiled: March 2, 1987Date of Patent: March 15, 1994Assignee: The BOC Group, plcInventor: Richard W.

Patent number: 5058928Abstract: The auxiliary device is in the form of a disk-shaped body having a front face, a rear face and lateral side wall surfaces. A cylindrical bore hole extends through the body from its front face to its rear face and it has a diameter that is slightly smaller than the outer diameter of the retractable spring-loaded sleeve of an air hose quick-disconnect coupling so that the auxiliary device may be manually slid on over the tubular sleeve and frictionally held thereto. The diameter of the front face of the disk-shaped body is sufficiently large enough that the hand of the person connecting or disconnecting the end of an air hose to the coupling can push his hand against the front face to move the spring loaded sleeve rearwardly while engaging or disengaging the end of the air hose.Type: GrantFiled: April 19, 1991Date of Patent: October 22, 1991Assignee: Richard Wayne WatsonInventor: Richard W.

Patent number: 4853206Abstract: A gas mixture including sulphur dioxide is recovered from sulphate waste material by burning a fuel to form a flame zone, introducing sulphate waste material into the zone and introducing pure oxygen or other oxygen-rich gas into the flame zone to support combustion of the fuel and to generate a flame of sufficient temperature to crack solid sulphate waste material and thereby liberate sulphur dioxide therefrom. Solids exiting the flame zone are separated from the gaseous combustion products. The sulphate waste material may be taken from a plant for making titanium dioxide pigment by the sulphate route.Type: GrantFiled: May 1, 1987Date of Patent: August 1, 1989Assignee: The BOC Group plcInventor: Richard W.

Patent number: 4256721Abstract: In a process for thermally cracking waste sulphuric acid, a combustible material is mixed with such acid and the mixture is supplied to a burner to which a flow of atomizing air is also supplied. A flow of secondary air which is enriched to about 23-40% by volume of oxygen is injected into a flame generated by burning said waste sulphuric acid-combustible material mixture to thereby thermally crack such acid while reducing the production of by-product sulphur trioxide.Type: GrantFiled: February 23, 1979Date of Patent: March 17, 1981Assignee: BOC LimitedInventors: Philip G. Blakey, Richard W. Watson

Patent number: 4235858Abstract: In a process for producing nitric acid, a mixture of oxygen, nitrogen, nitric oxide, nitrogen dioxide, and dinitrogen tetroxide is introduced into an absorption column into which cold oxygen (below 0.degree. C.) is introduced. H.sub.2 O is introduced into the upper reaches of the column and reacts with the nitrogen dioxide and dinitrogen tetroxide to form nitric acid. The low oxygen temperature helps to shift the equilibrium between nitric oxide and oxygen to dinitrogen tetroxide and in favor of reacting the latter with water to form nitric acid.Type: GrantFiled: April 6, 1979Date of Patent: November 25, 1980Assignee: BOC LimitedInventors: Philip G. Blakey, Bryan K. Smith, Richard W. Watson

Patent number: 4188793Abstract: In a process for condensing the vapor of a volatile liquid, such as vinyl chloride monomer, a gaseous mixture comprising the vapor of the volatile liquid and a non-flammable gas, such as nitrogen, is heat exchanged with a liquid refrigerant or vapor evolved therefrom, or both, the heat exchange being performed such that condensate of the vapor of the volatile liquid is produced at a directly or indirectly controlled temperature which is between the boiling point of the volatile liquid at atmospheric pressure and the boiling point of the refrigerant at atmospheric pressure and which is also between the boiling and freezing points of the volatile liquid at the prevailing pressure at which the condensate is formed, the non-flammable gas remaining uncondensed; the condensate is collected; the uncondensed gas is warmed to a temperature, and then vented to the atmosphere.Type: GrantFiled: July 25, 1977Date of Patent: February 19, 1980Assignee: BOC LimitedInventors: Richard W.

Patent number: 4183906Abstract: An improved process for the manufacture of nitric acid involving catalytic oxidation of ammonia and passage of the resulting nitric oxide through columnar absorption zones, the improvement particularly comprising oxygen-enrichment of that gas passing through the absorption zones at one or more regions of the zones wherein the absorption reaction is from 50 to 90% complete. Further, the invention contemplates the oxygen-enrichment of bleaching air and a reduction in the rate at which bleaching air or other air is taken to form secondary air. The invention results in improved production rates of nitric acid and reductions in the concentration of nitrogen oxides in vent gas.Type: GrantFiled: June 15, 1978Date of Patent: January 15, 1980Assignee: BOC LimitedInventors: Richard W.
