A process for the manufacture of ether from a feedstock containing isoolefins and linear olefins. The process is one which has a high conversion of isoolefins thereby permitting the separation of linear olefins without the associated difficulty in separating isomers.

Process for manufacturing ether and high purity butene-1

This invention provides an improved etherification process that reduces the amount of acidic-ion-exchange-resin catalyst that is deactivated by nitriles. This process uses a water phase to remove nitriles from a hydrocarbon phase followed by an alcohol phase to remove the nitriles from the water phase. An hydrogenation catalyst is used to convert the nitriles to amines so that they can be more easily removed from the alcohol phase.

Etherification process

A combination process wherein a hydroisomerization system provides a hydrocarbon feed for an etherification system wherein unreacted alcohol is separated from the etherification effluent and passed to the fractionation column used in the hydroisomerization system so that water entrained in the unreacted alcohol can be separated from said alcohol within said fractionation column.

Recycle of alcohol in a combined hydroisomerization and etherification

This invention provides a process to remove nitriles. This invention also provides an improved etherification process that reduces the amount of acidic-ion-exchange-resin catalyst that is deactivated by nitriles. These processes use a water phase to remove nitriles from a hydrocarbon phase followed by a steam, or fuel gas, phase to remove the nitriles from the water phase.

Nitrile removal process and etherification process with same

A process for producing ethyl tertiary butyl ether and for the substantially complete recovery by fractional distillation of the unreacted ethanol contained in an etherification reaction zone product stream as a product along with the ethyl tertiary butyl ether reaction product. This process utilizes methanol as a fractionator feed additive to enhance the recovery of ethanol as a bottoms product.

Enhanced recovery of alcohol from an ether containing stream

A process for producing a high purity ether product. This process includes utilizing an additive stream, which preferably contains isobutane, to alter compositions of the overhead and bottoms products of an etherification effluent fractionator so that the alcohol concentration in the overhead product is less than that of the azeotropic composition.

Production of a high purity ether product

An etherification process for reacting tertiary olefin compounds with primary alcohols to produce an ether product. The etherification process has the advantage of permitting dual operating modes for producing methyl tertiary butyl ether and tert amyl methyl ether and it provides high conversion across the etherification process of the tertiary olefin compounds.

A novel integrated olefin processing scheme is provided where olefins and paraffins are processed to produce high octane gasoline blending components. The integrated process involves the dehydrogenation of paraffin compounds to olefin compounds and the processing of olefins by hydroisomerization to produce hydroisomerate streams which are subsequently etherified. Those olefin compounds which are not etherified pass to an alkylation process where they are alkylated with branched chain paraffin compounds to produce an alkylate product.

Integrated olefin processing

A reformer optimization system including the injection of non-reactive gas into hydrogen recycle gas for increasing hydrogen flow through a recycle compressor. Non-reactive gas is injected into hydrogen-rich gas fed to the compressor at least as early as the hydrogen-rich gas enters the compressor. The quantity of hydrogen is monitored, and the quantity of non-reactive gas injected is controlled in response to the hydrogen quantity. By maintaining a substantially constant molecular weight of the hydrogen gas, hydrogen content thereof is increased. The non-reactive gas is preferably at least one of a group comprising nitrogen, ethane and propane.
