Patent ID: 7445758

Claim:
A method of performing a continuous chemical reaction between at least a first fluid reactant and at least a second fluid reactant to form a reaction product comprising: (i) continuously introducing a first fluid feed containing said first fluid reactant into a first end of a tubular reaction zone having a length whereby first fluid reactant continuously flows towards a second end of said tubular reaction zone; and (ii) continuously introducing a second fluid feed containing said second fluid phase reactant into said tubular reaction zone at a multiplicity of points along the length of said tubular reaction zone by passing said second reactant through a multiplicity of injectors spaced apart lengthwise along said tubular reaction zone, whereby the amount of said second reactant passed through at least one of said injectors is controlled by a pressure drop control means proximate to the injector; and (iii) providing conditions conducive to said chemical reaction in said tubular reaction zone whereby said chemical reaction proceeds and said reaction product is formed.
