Abstract
A method and analyzer for monitoring the progress of a chemical process in which a fixed volume sample of the reactive mixture of the chemical process is periodically gathered and injected into a fluid stream of a liquid carrier. The sample in the liquid carrier is passed through an infrared detector which detects the amount present in the sample of a species of the reaction mixture which is indicative of the progress of the chemical process.
Claims9
An analyzer for monitoring a chemical reaction in a chemical process comprising:
- a. a sample gatherer for gathering a sample of a reaction mixture of the chemical process;
- b. a source of a dry organic liquid carrier, containing a quenching agent, to provide a flow stream thereof;
- c. an injector for injecting the sample into a flow stream of said dry organic liquid carrier;
- d. an infrared detector for detecting an amount of a particular species of the reaction mixture in the sample which is indicative of the progress of the chemical process, and
- e. means for passing said flow stream of dry organic liquid carrier with said sample through said infrared detector.
An analyzer for monitoring a chemical reaction in a chemical process comprising:
- a. a sample gatherer for gathering a sample of a reaction mixture of the chemical process;
- b. a source of a dry organic liquid carrier, containing a quenching agent, to provide a flow stream thereof;
- c. an injector for injecting the sample into a flow stream of said dry organic liquid carrier;
- d. an infrared detector for detecting an amount of a particular species of the reaction mixture in the sample which is indicative of the progress of the chemical process, and
- e. means for passing said flow stream of dry organic liquid carrier with said sample through said infrared detector,
- wherein said sample gatherer and said injector include means for periodically gathering and injecting a plurality of samples during the chemical process and passing said flow stream with each said sample through said detector.
An analyzer for monitoring a chemical reaction in a chemical process comprising:
- a. a circulating line for circulating a portion of the reaction mixture of the chemical process from the chemical process through a sample infeed line and back to the process;
- b. a diverter for diverting a portion of the reaction mixture portion being recirculated from the sample infeed line to a sample gatherer;
- c. a sample gatherer for gathering a fixed volume of sample of the reaction mixture of the chemical process;
- d. an injector for periodically injecting the fixed volume of sample into a flow stream of an organic liquid carrier;
- e. an infrared detector for detecting an amount of a particular species of the reaction mixture in the sample which is indicative of the progress of the chemical process, and
- f. means for passing said flow stream of said organic liquid carrier, containing a quenching agent, with the fixed volume of sample through said infrared detector.
