Systems and methods are provided for use in communicating with a distributed control system (DCS) associated with a manufacturing plant. One example system includes a virtual machine hosted in a computing device and coupled to the DCS via a network connection, where the virtual machine includes a controller server and a controller client. The controller server includes a controller specific to a process of the plant, and the controller client is configured to host communication between the controller server in the virtual machine and the DCS of the plant. The controller client, then, is further configured to receive a message from the DCS, via the network connection, transform the message into a JSON message, and communicate the JSON message to the controller server.

Systems and methods for providing a virtual machine link to process controls

The present invention generally relates to processes for purification, recovery, and conversion of chlorophenol salts (e.g., 2,5-dichlorophenol and salts thereof). In various aspects, the present invention is related to removing one or more impurities from chlorophenol salt-containing process streams and/or recovering chlorophenol salts from process streams for use of the recovered chlorophenol elsewhere in an integrated process. Process streams that may be treated in accordance with the present invention include those incorporating one or more chlorophenol salts in a feed mixture and also those where one or more chlorophenol salts are present in a product or by-product stream of an integrated process. For example, conversion processes of the present invention are suitable as one piece of an integrated process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or a salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or a salt or ester thereof. The present invention further relates to processes for preparation, purification, and recovery of intermediates formed in integrated processes utilizing chlorophenol salts such as 2,5-dichlorophenol as starting material, including the intermediate 3,6-dichlorosalicylic acid (3,6-DCSA) formed during preparation of dicamba from 2,5-dichlorophenol.

Various processes for the separation of a mixture containing dichlorophenols are described. In various aspects, the present invention relates to separation processes that produce an extract enriched in 2,4-dichlorophenol content and an extract enriched in 2,5-dichlorophenol content. The present invention further relates to various processes that integrate with these separation processes, such as a process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or salt or ester thereof.
