PROCESSES AND APPARATUSES FOR HEATING A HYDROCARBON PROCESS STREAM
Processes and apparatuses for heating a hydrocarbon process stream, with an electrical heater to provide a portion of the heat requirement necessary for a chemical reaction to occur to one of the components of the hydrocarbon process stream. The electric heater may be in series or in parallel with a second, or main heater. The electric heater may be used between two reaction zones or between a feed exchange heater and a first reaction zone. The electric heater preferably provides between 5 to 40% of the heating requirement for the process stream.

DEVICE AND METHOD FOR CRACKING BORON TRIFLUORIDE COMPLEX
The present disclosure relates to the technical field of separation of boron isotopes, in particular to a device and method for cracking a boron trifluoride complex. The device for cracking the boron trifluoride complex includes a continuous feeding system, a rising film preheater, a falling film preheater, a boron trifluoride gas circulation pipeline, a separation chamber, a cracking tower, a gas-liquid separator, an impurity removal tower, and anisole storage tank. By employing a continuous feeding method, the device for cracking boron trifluoride complex shortens retention time of anisole at a high-temperature stage while ensuring a cracking rate of a boron trifluoride-anisole complex, reduces the thermal decomposition degree of anisole, maintains the purity of anisole, and greatly improves the utilization rate and production safety of anisole, thus ensuring continuous and stable production.
