Abstract: A method for treating the waste stream from a purified terephthalic acid (PTA) process is provided. The method comprises contacting a waste stream containing carbon monoxide (CO), volatile organic compounds (VOCs), and methyl bromide with a catalyst comprising a first base metal catalyst supported on an oxygen donating support that is substantially free of alumina, and at least one second base metal catalyst.

Abstract: A catalyst for oxidizing carbon monoxide (CO), volatile organic compounds (VOCs), and methyl bromide (CH3Br) is provided. The catalyst comprises a first base metal catalyst supported on an oxygen donating support that is substantially free of alumina, and at least one second base metal catalyst. Also provided is a method for treating the waste stream from a purified terephthalic acid (PTA) process, the method comprising contacting a waste stream containing carbon monoxide (CO), volatile organic compounds (VOCs), and methyl bromide with a catalyst comprising a first base metal catalyst supported on an oxygen donating support that is substantially free of alumina, and at least one second base metal catalyst.

Abstract: A method, apparatus and program storage device for enabling multiple asynchronous direct memory access task executions. DMA I/O operations and performance are improved by reducing the overhead in DMA chaining events by creating a software DMA queue when a hardware DMA queue overflows and dynamically linking new DMA requests to the software queue until a hardware queue becomes available at which time the software queue is put on the hardware queue. Thus, microcode does not need to manage the hardware queues and keep the DMA engine running continuously because it no longer has to wait for microcode to reset the DMA chain completion indicator.

Abstract: A mail dispatch system for a computer subsystem has at least one data processing server. An interface device is configurable to electrically couple to the server. The device has an input/output (I/O) port for sending and receiving information A mail dispatch module is adapted to be operable on the interface device. The module includes a mail dispatch algorithm adapted to identify a first number of data processing servers, identify a second number of I/O ports and calculate an optimal mail dispatch unit based on the first and the second numbers.
