Novel processes are provided for the cooling of light hydrocarbon cracker effluent streams using Liquefied Natural Gas (LNG). The effluent streams are passed through LNG cold boxes where they are cooled by LNG. The cooling takes place as a result of direct or indirect heat transfer. As the LNG heats up from this process it can be fed into a light hydrocarbon cracker. The use of the present processes offers significant economic and environmental benefits over the typical industry practice of compression and cooling using C2/C3 refrigerants.
A process for cooling an effluent stream of a light hydrocarbon cracking unit using liquefied natural gas (LNG) comprising:
A process for cooling the effluent stream of a light hydrocarbon cracker using liquefied natural gas (LNG) comprising:
A process for cooling the effluent stream of a light hydrocarbon cracker with LNG, comprising passing LNG and cracked gas from the light hydrocarbon cracker to a column or contractor where the LNG comes into direct contact with the cracked gas.
