Abstract
A light reaction chemical processing system uses for proceeding a photochemical reaction of organic liquid and active material gas to form the target substance. In said light reaction chemical processing system, said active material gas and said organic liquid form a mixture in a gas and liquid mixing apparatus, and said photochemical reaction of the mixture was proceeded through a UV light source unit in a photochemical reaction apparatus in order to form a crude product containing the target substance. Then, said crude product is cooled by a cooling device and then enters a treatment device. Said target substance is separated from said crude product in said treatment device, and said treatment device is capable of storing the crude product in which said target substance has been separated for recycling the crude product to said gas and liquid mixing apparatus. A feeding device is used to replenish at least one of said organic liquid or said active material gas into the crude product in which said target substance has been separated to achieve a continuous process.
