Abstract
This invention is directed to a system and a process for protecting a gas purification system from damage comprising passing a stream of impure gas through a catalyst bed and measuring the temperature difference before and after the catalyzed bed reaction through a data analyzer to determine the impurity of the gas prior to controlling the feed of impure gas into or out of a reactor for producing a purified gas. In a preferred embodiment, the catalytic beds may be in parallel form, and the plurality of temperature measurements before and after the catalytic beds is considered by a data analyzer for controlling the impure gas for feeding into the purification reactor.
Claims16
A process for protecting a gas purification system from damage comprising:
- a) passing a first impurity-containing gas stream into a data analyzer flow scheme;
- b) passing a second reactant-containing gas stream into the analyzer flow scheme;
- c) mixing said first impurity-containing gas stream with the second reactant-containing gas stream to form a mixed gas stream;
- d) passing said mixed gas stream to a first temperature measuring device to determine its temperature and passing the resulting temperature data to a data analyzer;
- e) passing the mixed gas stream from step d) to a catalytic bed to allow the reaction in the mixed gas stream to proceed, and forming a reacted mixed gas stream;
- f) passing the reacted mixed stream to a second temperature measuring device to determine its temperature and passing the resulting temperature data to said data analyzer;
- and
- g) controlling the flow of the first impurity-containing gas stream passing to or from the gas purification apparatus based on data received from the data analyzer.
A process for protecting a gas purification system from damage comprising:
- a) passing a first impurity-containing gas stream into a data analyzer flow scheme and a gas purification apparatus;
- b) passing a second reactant-containing gas stream into the analyzer flow scheme;
- c) mixing said first impurity-containing gas stream with the second reactant-containing gas stream to form a mixed gas stream;
- d) separating the mixed gas stream into a plurality of split streams;
- e) passing one of the split streams to a first temperature measuring device to determine its temperature and passing the resulting temperature to a data analyzer;
- f) passing the resulting split stream from step e) to a reaction vessel to purify said resulting split stream;
- g) passing the resulting split stream from step f) to a second temperature measuring device to determine its temperature and passing the resulting temperature to the data analyzer;
- h) repeating the steps of e) to g) with another split stream through corresponding temperature measuring devices and reaction vessels;
- and
- i) controlling the flow of the first impurity-containing gas stream passing to the gas purification apparatus based on data received from the data analyzer.
