Paperitalo: Today we are talking to George Pemble about the SMS2000 Soap Management System.

Paperitalo: George, tell us. What problem does the SMS2000 Interface System solve?

Pemble: Soap is skimmed from softwood Kraft liquor. Traditionally black liquor tanks have relied on DP cell instrumentation to display level. This cannot detect the most critical parameter which is the interface level between the soap and liquor. This can lead to soap attacks on the multiple effect evaporators if this interface gets too low or spillage if soap overflows the tank.

Paperitalo: So, how does the SMS2000 Interface System solve this problem?

Pemble: The SMS2000 Interface System detects and remotely displays the exact interface level on a continuous basis without any maintenance or periodic calibration needed.

Paperitalo: How does this work?

Pemble: The SMS2000 Interface System has an ingenious float and electronic monitoring system that continuously reports the interface level in your system. The output is a 4/20 milliamp signal which is converted to a level indication. This can then be displayed in the control room as the interface level in the tank. It does this with a sensor system where there is no contact between the sensors and the extremely hostile environment found in this area. Very importantly, it can be installed in most black liquor tanks while they are in normal operation.

Paperitalo: Are there other process benefits from the SMS2000 installation?

Pemble: Yes -- the ability to see the interface will allow for better soap skimming which can enhance soap recovery and further limit the soap load on the multiple effect evaporators.

Paperitalo: As I recall, the recovery area of the mill is not the gentlest place to put instrumentation. What's the story so far?

Pemble: We have over two dozen systems installed, the first one is over 15 years old. No problems.

Paperitalo: George, that sounds great. How do people reach you to find out more?

Pemble: They can call me at 409-898 -7678 or email me at gpemble@pembleconsulting.com
