Abstract
Processes and apparatuses for toluene methylation in an aromatics complex for producing paraxylene. More specifically, the present disclosure relates to processes and apparatuses wherein a toluene methylation zone is integrated within an aromatics complex for producing paraxylene thus allowing no benzene byproduct to be produced. This may be accomplished by incorporating a toluene methylation process into the aromatics complex and recycling the benzene to the transalkylation unit.
Claims20
A system for improving operation of a petrochemical plant, the system comprising:
- a column;
- a reactor;
- one or more heaters;
- a compressor;
- one or more sensors configured to collect plant data related to operation of the petrochemical plant, the plant data associated with at least one of the column, the reactor, the one or more heaters, or the compressor;
- a collection platform comprising:
- one or more processors;
- and
- memory storing executable instructions that, when executed by the one or more processors of the collection platform, cause the collection platform to:
- receive the plant data from the one or more sensors;
- an interface platform comprising:
- one or more processors;
- and
- memory storing executable instructions that, when executed by the one or more processors of the interface platform, cause the interface platform to:
- provide an interface between the collection platform, a database configured to store the plant data, and a communication network;
- and
- receive, via the communication network and from the collection platform, the plant data related to operation of the petrochemical plant;
- and
- an optimization platform comprising:
- one or more processors;
- and
- memory storing executable instructions that, when executed by the one or more processors of the optimization platform, cause the interface platform to:
- analyze for completeness the plant data related to operation of the petrochemical plant;
- correct the plant data for a measurement issue and an overall mass balance closure;
- generate a set of reconciled plant data based on the corrected plant data;
- determine, based on the reconciled plant data, a recommendation for an optimization to a process of the petrochemical plant;
- and
- transmit, to a remote device, the recommendation for the optimization to the process of the petrochemical plant based on the reconciled plant data.

A method for improving operation of a petrochemical plant comprising a column, a reactor, one or more heaters, and a compressor, the method comprising:
- receiving, from one or more sensors, plant data related to operation of the petrochemical plant, the plant data associated with at least one of the column, the reactor, the one or more heaters, or the compressor;
