Dry Air for Process Instrumentation

Commonly found in the petrochemical industry, analyzer buildings are the control center of modern refineries and chemical plants. Process instruments utilize sensitive, air-operated stream control valves to take samples of process streams. The analyzers assure product quality by sending feedback to process control valves that fine tune process parameters.

Instrument grade air is needed for the control systems and must be of the highest quality to assure maximum up-time. Downtime of any instrumentation can cost thousands of dollars per hour.

Most analyzer buildings utilize plant instrument air. In many plants this air is of unreliable quality Often, due to system upsets, the compressed air can become contaminated with oil and water. In addition, warm plant air entering the air conditioned building can cause condensation. This contamination can ruin the performance of sensitive process analyzers and control valves and cause production setbacks.

To assure that the analyzer building has zero downtime, a final point-of-use air dryer is required. The air dryer acts as a final line of defense and assures no condensation in the air lines.

Membrane air dryers are ideal for this application as they do not require electricity and therefore are safe to use in all Class 1 Div 2 installations. The Parker Balston 76 Series Air Dryer assures a continuous supply of instrument grade air.


Sample Conditioning

There are many requirements throughout refineries, petroleum and chemical facilities where sample analysis is critical to the operation and production output. Sample analysis instrumentation are adversely effected by condensed contaminants, gas bubbles and solid contaminants both of which can also skew the analysis output. Efficient removal of undesirable contaminants from a sample stream will ensure accurate analysis and trouble-free operation of the instrumentation.

Prevention of Flares Gas Blowback and Pipe Flushing

Natural gas flares are subject to blowback. A nitrogen blanket to the flame prevents this dangerous condition. Nitrogen can also be used to flush pipes that are used to transport flammable gases. Parker Balston or domnick hunter Nitrogen Generators can economically create nitrogen on demand from compressed air. Using membrane technology, nitrogen can be generated without the use of electricity so membranes are safe to have in Class 1 explosion proof settings.
