Mr. Johnson, We had a consultant do a RACT analysis on our LPISM VOC emission controls in circa 1993. That study showed that water scrubbing was the most economical at approx. $1600/ton of VOC controlled. (Thermal incineration was the most costly at over $13,000/ton!). These costs included an amortized cost of the capital cost of the equipment in addition to the operating costs. However, the installed cost of a water scrubber are less than $100K.

Our goal 100% solven elimination. We are looking for information on the cost for PCB manufacturers to handle solvent emissions from liquid photoresist and soldermask during application and soft-bake. Cost of ventilation, scrubbers, etc. Steven Johnson IPS ************************************************************************** * The mail list is provided as a service by IPC using SmartList v3.05 * ************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ************************************************************************** * If you are having a problem with the ComplianceNet forum, please call * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ************************************************************************** ************************************************************************** * The mail list is provided as a service by IPC using SmartList v3.05 * ************************************************************************** * To unsubscribe from this list at any time, send a message to: * * [log in to unmask] with <subject: unsubscribe> and no text. * ************************************************************************** * If you are having a problem with the ComplianceNet forum, please call * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * **************************************************************************
