Patent number: 8865928Abstract: Apparatus and processes for removing dioxane from a composition, e.g., an ethoxylated fatty alcohol sulfate paste, utilize an evaporator having an inlet chamber and one or more heated channels. The process includes the step of heating the composition at a location upstream of the flow restriction to a temperature above the flashing temperature of water at a pressure of the channel inlet and applying a pressure to the heated composition to avoid such flashing. The process further includes the step of passing the pressurized, heated composition through the evaporator. The process can further include injecting a vapor into the channel. The purified, concentrated product can be diluted with water to a desired concentration.Type: GrantFiled: October 8, 2013Date of Patent: October 21, 2014Assignee: The Chemithon CorporationInventors: Walter A. Jessup, Burton Brooks, W. Brad Sheats

Patent number: 6058623Abstract: Apparatus and processes for removing volatile components from a composition utilize a dryer having an inlet chamber and a plurality of channels. A flow restriction is disposed immediately upstream of the inlet of each channel with respect to a direction of flow of the composition through the dryer. The process includes the step of heating the composition at a location upstream of the flow restriction to a temperature above the flashing temperature of at least one of the components at a pressure of the channel inlet and applying a pressure to the heated composition to avoid such flashing. The process further includes the step of passing the pressurized, heated composition through the dryer inlet chamber, the flow restriction, and through the channels.Type: GrantFiled: February 27, 1998Date of Patent: May 9, 2000Assignee: The Chemithon CorporationInventors: Burton Brooks, Walter A.

Patent number: 5723433Abstract: A method of removing solvents from a paste includes introducing a heated paste into a channel of a dryer under pressure selected so as to avoid flashing of any of the components of the paste. At the inlet of the channel, the pressure is dropped, resulting in the flashing of selected components of the paste. As the paste advances through the channel heat is applied to the paste. Vapor liberated during the flashing acts as a motive force to convey the paste along the channel. The resulting concentrate is collected at an outlet of the channel.Type: GrantFiled: June 7, 1995Date of Patent: March 3, 1998Assignee: The Chemithon CorporationInventors: Lanny R. Duvall, Burton Brooks, Walter Jessup

Patent number: 5244642Abstract: A method for conditioning flue gas to improve the removal of fly ash by an electrostatic precipitator employs a relatively high concentration (4-71/2%) of SO.sub.3 conditioning agent. The SO.sub.3 is formed by combusting sulfur and excess air in a sulfur burner to produce a mixture of air and SO.sub.2 and converting the SO.sub.2 to SO.sub.3 in a catalytic converter. The ratio of air to sulfur is maintained constant over a wide range of SO.sub.3 production rates, and the air is unheated during most production rates. The mixture of air and SO.sub.2 from the sulfur burner is cooled without increasing the volume of the gaseous mixture.Type: GrantFiled: June 18, 1992Date of Patent: September 14, 1993Assignee: The Chemithon CorporationInventors: William G. Hankins, Burton Brooks, John C. Chittenden, William B. Sheats, Patrick J. Bader

Patent number: 4587029Abstract: Anhydrous fatty alcohol sulfuric acid or ethoxylated fatty alcohol sulfuric acid is neutralized with dry sodium carbonate powder in the presence of powdered sodium tripolyphosphate in a high shear mixer. The dry, powdered, neutralized reaction product is stored until required for use in the manufacture of a detergent bar whereupon the powder is mixed with liquid ingredients for the detergent bar and subjected to conventional manufacturing steps for a detergent bar. Other dry, powdered ingredients for the detergent bar may be introduced at the high shear mixer.Type: GrantFiled: November 16, 1984Date of Patent: May 6, 1986Assignee: The Chemithon CorporationInventor: Burton Brooks

Patent number: 4374058Abstract: A first slurry containing alkyl benzene sulfonate is spray-dried to form dry, powdery particles which are introduced into a rotary drum mixer along with dry, powdery particles of other detergent ingredients. The dry, powdery particles are lifted and dropped in the mixer to form a descending curtain into which is sprayed a second slurry containing alpha olefin sulfonate, thereby agglomerating the ingredients into composite particles, each of which contains all the ingredients introduced into the mixer.Type: GrantFiled: October 26, 1981Date of Patent: February 15, 1983Assignee: The Chemithon CorporationInventor: Burton Brooks

Patent number: 4267119Abstract: An organic reactant is sulfonated by injecting it into a stream of gas comprising sulfur trioxide, at a venturi, and the resulting reaction mixture is quenched with a stream of cooled, recycled reaction product immediately downstream of the venturi in a conduit in which particles of reaction mixture are agglomerated into a film of the recycle stream and in which additional sulfonation reaction occurs.Type: GrantFiled: December 21, 1979Date of Patent: May 12, 1981Assignee: The Chemithon CorporationInventors: Burton Brooks, Richard J.

Patent number: 4251456Abstract: A relatively large amount of SO.sub.2 effluent gas from a sulfonation process is converted to SO.sub.3 and recycled back to the sulfonation process as part of the SO.sub.3 sulfonating agent. The rest of the SO.sub.3 used as the sulfonating agent is derived from a sulfur burner located downstream of the sulfonation operation and in the recycle path of the SO.sub.2 in the effluent gas. Hydrocarbons in the effluent gas are converted to CO.sub.2 and H.sub.2 O in the sulfur burner. The H.sub.2 O and SO.sub.3 are removed from the gas stream at an SO.sub.3 absorber which forms rich oleum from which the SO.sub.3 is subsequently removed for use in the sulfonation operation, leaving lean oleum which is used at the SO.sub.3 absorber to remove H.sub.2 O and SO.sub.3 from the gas stream. Gases leaving the SO.sub.3 absorber include some SO.sub.3 and are passed through an H.sub.2 SO.sub.4 absorber along with water and lean oleum to produce concentrated H.sub.2 SO.sub.4.Type: GrantFiled: March 29, 1979Date of Patent: February 17, 1981Assignee: The Chemithon CorporationInventor: Burton Brooks

Patent number: 4216001Abstract: A scrubbing system including scrubbers having straight through or direct line gas flow, with steam pretreatment of the gases supplied to the scrubber. The scrubbing solution may be recycled. Where steam is present in the process, the effluent gas is partially recycled to the process upstream of the scrubber to maintain a predetermined level of steam moisture in the gases entering the scrubber.Type: GrantFiled: January 10, 1979Date of Patent: August 5, 1980Assignee: The Chemithon CorporationInventors: Richard J.
