Abstract: The invention is directed to a method of generating at least one long half-life free radical by an electrochemical cell, said apparatus having suitable electrode plates, which comprises the following steps: passing an aqueous solution containing unwanted contaminants through at least one pair of electrodes to which a DC electrical current is passed in such a fashion that at least one long half-life free radical is created which initiates an enduring, i.e. continuing, chain reaction which will consume or destroy any available contaminants, wherein the DC electrical current is controlled so as cause the potential difference across the electrochemical cell to be at a controlled rate to achieve a precise value within a specified time.

Abstract: According to the invention a system and method for catalyst removal from MTO effluent is provided. The method includes removing catalyst from methanol to olefin effluent including contacting the methanol to olefin effluent with a wash oil separate the catalyst fines from the effluent into the wash oil and cool the effluent, separating the catalyst fines from the cooled effluent in a separator or a column to obtain an essentially catalyst free effluent, directing the catalyst free effluent out from the separator or the column, slurrying the separated catalyst fines to obtain a slurry and directing the slurry to one or more filters to filter out the catalyst.

Abstract: Provided is a wastewater treatment process using an electrochemical electrode device. The electrochemical electrode device comprises at least one electrochemical electrode (30) comprising an appropriate electrode plate. The process comprises the following steps: causing water containing an undesired solute to pass through at least one electrochemical electrode (30); applying a direct current to the electrochemical electrode (30) to destroy the undesired solute in the water so as to output water having a lower concentration of the undesired solute. The direct current is adjusted via a specific power control procedure. The control procedure at least comprises the following cycle of an applied current sequence: a period of operation with a preset constant current flowing through an electrochemical electrode (30); applying a reverse constant current to reverse positive and negative electrodes while maintaining an absolute magnitude of the constant current; and a period of operation with the constant current flowing through the electrochemical electrode (30).
