The versatile AMETEK 5000 is a highly sensitive moisture analyzer for process applications where the continuous, reliable measurement of moisture in vapors and gases is required. The 5000 analyzer measures moisture on-line by monitoring the vibrational frequency change of a hygroscopically sensitized quartz crystal that is exposed alternately to wet sample and dry reference gas for 30 second periods. The reference gas is sample gas passed through a molecular sieve dryer to remove virtually all its moisture content.
Problem - Proper moisture balance in feedstocks and hydrogen recycle streams must be maintained to optimize product yield and catalyst life. Measurement reliability is greatly complicated by the presence of compressor oils and high boiling point hydrocarbons in the stream. The reformer process typically requires accurate and rapid results despite variations in moisture content from 10 to 25 parts per million.
Solution and Results - The 5000s accuracy, reliability, and fast response are not affected by normal reformer contaminants such as compressor oils and high boiling point hydrocarbons. The on-board moisture generator verifies measurement accuracy for optimum product yield. Readings are absolute and provable, not just trends.
