Processes for producing isophthalic acid are disclosed, the processes including a step of combining in a reaction medium meta-xylene, a solvent comprising water and a saturated organic acid having from 2-4 carbon atoms, and an oxygen-containing gas, at a temperature for example from about 145&#xb0; C. to about 175&#xb0; C., in the presence of a catalyst composition comprising cobalt, manganese, zirconium, and bromine, wherein the zirconium is present in the reaction medium in an amount, for example, from about 1 ppm to 50 ppm with respect to the weight of the liquid in the reaction medium.

An MHT reactor is added to a DMT process to eliminate the majority of the DMT/MHT recycle back to the DMT reactor, allowing for an increase in capacity to the DMT reactors.

A classifier for classifying particulates entrained in a flowing stream of gas is configured such that a change of direction of gas flow causes particles to impinge upon a target, heavier particles being trapped in a downwardly extending fluidized trap. The classifier is easily constructed, has no moving parts, and can take the place of sifters and other equipment traditionally used for classifying such product streams.

In a method for removing dimethyl ester vapors or particles emitted from a molten dimethyl ester storage tank, a gaseous mixture containing dimethyl ester vapors or particles and an inert gas are supplied to an inlet port of a water scrubber. Water is continuously sprayed through downstream spray nozzles located inside the water scrubber whereby the water and air mix with the gaseous mixture to form a foamy mixture of dimethyl ester, air and water. Water through an upstream spray nozzle located inside the water scrubber is intermittently sprayed to wash an inner wall of an elongated body and the inlet port of the water scrubber to remove buildup of dimethyl ester particles. The foamy mixture is continuously removed from an outlet port. The water scrubber utilized in the method has an elongated body having an inner wall, a top with an orifice for receiving air, and a bottom with an outlet port. The inlet port is positioned on the body between the top and the bottom of the water scrubber. At least one upstream water spray nozzle is positioned between the inlet port and the top. At least two downstream spray nozzles are positioned between the inlet port and the outlet port. The spray nozzles operates with a downward flow of water.
