摘要:
A method and system of storing and transporting valuable gases comprising mixing the gases with liquid natural gas to form a mixture. The mixture is transported in vessel configured for cooling the mixture by boiling a portion of liquid natural gas. The transportation vessel is further configured to be cooled in the absence of valuable gases by a remaining portion of liquid natural gas. The method further comprises recycling liquid natural gas through the vessel for pre-cooling the vessel prior to loading the mixture of valuable gases and liquid natural gas.
摘要:
Disclosed is a method for determining when to replace a guard bed material used to remove one or more catalyst poisons from a feed based on a parameter change in a process. A guard bed having a guard bed material is in fluid communication with a catalyst bed having a catalyst. At least three monitors are positioned in said guard bed or said catalyst bed and at least one parameter of the guard bed or catalyst bed is monitored. A feed component comprising one or more catalyst poisons is supplied to said guard bed or said catalyst bed. The feed is contacted with said guard bed material or said catalyst to remove at least a portion of a catalyst poison and to form a product which produces an increase or a decrease in said parameter. The monitored parameters are compared to determine when to replace the guard bed material.
