Model 1221 Distillation Sample Probe

1221
The Universal Analyzers Model 1221 Distillation Sample Probe is a unique self-cleaning and temperature stabilized primary sample conditioning system for demanding on-line gas analysis applications. It is a direct replacement for the Fluid Data Reflux Sampler used for Pygas Sampling.

It is designed to solve the key issues that compromise plant performance by improving measurement accuracy and reliability. The 316SS self-cleaning separator is designed to condense and wash heavy components in the sample back into the process along with any deposited solids avoiding the regular ‘plugging’ that occurs with conventional conditioning systems. Maintenance of the probe is further simplified, as once isolated from the main-line, the separator can be removed without the need to remove the entire probe.

The sample probe uses a multiple-stage cooling design which is made entirely of 316SS. This provides efficient removal of entrained liquids due to its high surface area and thermal efficiency resulting from the unique cooling transfer design utilizing proprietary TraceBoost™ technology.

The high-performance probe design is ideal for use in applications such as ethylene furnaces, FCCUs and coke ovens. The dual vortex cooling system (feed-forward and feed-back control with the electronic control); ensures high-accuracy analyzer performance and protection against liquid carry-over, minimizing the effects of changes in ambient or process temperature. The unique vortex cooling design simultaneously cools the sample and removes particulates, water, and high boiling-point compounds. The electronic controller includes self-diagnostics with local and remote monitoring and displays, configurable fail-safe alarms, and DCS integration, eliminating the need for regular scheduled inspections.
