Systems and methods for integrated glycerol carbonate and/or urea production. This disclosure pertains to development of a process for production of glycerol carbonate and/or urea from ammonia, carbon dioxide and glycerol. The process integrates glycerol carbonate production into a urea production process. The urea produced in the production facility may be used to produce glycerol carbonate by reacting urea with glycerol. The ammonia generated by glycerol carbonate production may be recycled back to urea production. Unreacted urea from the glycerol carbonate production may be separated and recycled to the urea product stream. The systems and methods can reduce the cost for urea production and increase product value of the excessive glycerol produced from other chemical plants.

A method is provided for determining command-to-process correspondence. The method includes identifying, by the hardware processor, initial processes resulting from executions of container immutability change events for each of multiple containers in a cluster, based on an execution time, a process identifier and a process group identifier for each of the container immutability change events. The method further includes checking, by the hardware processor, if an initial process from among the identified initial processes matches an entry in a database that stores external container commands and at least one respective process resulting from executing each of the external container commands. The method also includes designating, by the hardware processor, a particular external command, from among the external container commands stored in the database, as having a correspondence to the initial process, responsive to the initial process matching the at least one respective process resulting from executing the particular external command.

The invention is directed to a process to continuously prepare a cyclic carbonate product by reacting an epoxide compound with carbon dioxide in the presence of a supported dimeric aluminium salen complex. The process is performed in a reactor comprising a slurry of the supported dimeric aluminium salen complex and liquid cyclic carbonate product. The produced cyclic carbonate is discharged from the reactor while the supported dimeric aluminium salen complex remains in the reactor. The liquid carbonate product is purified by means of distillation. Between the reactor and the distillation one or more buffer vessels are present having a volume of between 5 and 50 m.sup.3 per kmol of dimeric aluminium salen complex as present in the reactor.
