In one aspect, a hydroformylation reaction process comprises contacting an olefin, hydrogen, and CO in the presence of a homogeneous catalyst in a cylindrical reactor to provide a reaction fluid, wherein the reactor has a fixed height, and wherein a total mixing energy of at least 0.5 kW/m3 is delivered to the fluid in the reactor; removing a portion of the reaction fluid from the reactor; and returning at least a portion of the removed reaction fluid to the reactor, wherein the returning reaction fluid is introduced in at least two return locations positioned at a height that is less than 80% of the fixed height, wherein the at least two return locations are positioned above a location in the reactor where hydrogen and carbon monoxide are introduced to the reactor, and wherein at least 15% of the mixing energy is provided by the returning reaction fluid.

Hydroformylation reaction process

Catalytic metal loss when using a hydroformylation catalyst comprising an organophosphite ligand is ameliorated by adding CO to a strip gas vaporizer.

Hydroformylation process

A multi-reactor hydroformylation process wherein a common product-catalyst separation zone is employed.

A multi-reaction train hydroformylation process wherein a common product-catalyst separation zone is employed.

A process of controlling hydroformylation reaction fluid temperature involves controlling the flow rate of reaction fluid through an external heat exchanger.

A method of managing the heat of a chemical reaction process.

Heat management process

A process of controlling heavies in a recycle catalyst stream, particularly, for use in a continuous hydroformylation process of converting an olefin with synthesis gas in the presence of a hydroformylation catalyst to form an aldehyde product stream with subsequent separation of the catalyst for recycle to the hydroformylation step. Heavies are controlled, and preferably reduced, by means of feeding a recycle gas stream, taken as a portion of an over-head stream from a condenser, back to a vaporizer wherein the aldehyde product stream is separated.
