Freezing is a major issue in any natural gas system from the mainstream pipeline flow to the low pressure measurement and control stations. With thorough evaluation and careful planning of each application, proper selection of available options, and a good routine maintenance program freezing problems can be controlled and minimized. If these issues are ignored, the cost of fixing the resulting problems is almost always significantly more expensive than the cost of the preventive action not taken. At the low end of this, not replacing a 50.00 filter cartridge can cause the loss of a 3,000.00 pneumatic controller that can in turn cause a power plant to shut down at peak demand. Depending on contractual considerations this single event can cost in the hundreds of thousands of dollars and put not only the system at risk but people that depend on the electricity at risk. Avoiding freezing issues is a good investment that adds to the profitability of your company, and, is the responsible thing to do.
