Online Preprocessing System: "Reliable Guarantee" for Analytical Instruments

Context: Solution Description Text to translate: The long-term stable operation of online analyzers largely depends on the design quality of the sample pre-treatment system. Process media in petroleum and petrochemical industries often have characteristics such as high temperature, high pressure, dust, liquid content, and tendency to coke. If the samples are not treated properly before entering the analyzer, they can cause instrument clogging, damage, and data drift. We focus on the design and manufacturing of online pre-treatment systems. Relying on in-depth process understanding and rich engineering experience, we provide "clean, constant-temperature, constant-pressure" qualified samples for analyzers, ensuring the long-term stable operation of the analytical system.

Core Functions

Function	Description
Pressure and Temperature Reduction	Reduce the temperature and pressure of high-temperature, high-pressure samples to a range acceptable for the analyzer.
Filtration and Purification	Remove impurities such as solid particles and liquid droplets from the sample.
Heating and Insulation	Prevent condensation or crystallization of easily condensable media during transportation.
Pressure and Flow Regulation	Stabilize the sample pressure and flow to meet the analyzer's requirements.
Corrosion Treatment	Use corrosion-resistant materials and structures for corrosive media containing sulfur or acid.

Typical Application Scenarios

Application Field	Process Characteristics	Pre-treatment Requirements
Hydrogenation Units	High temperature, high pressure, hydrogen sulfide content	Pressure reduction, corrosion prevention, leakage prevention
Catalytic Cracking	Dusty, catalyst particle content	High-efficiency filtration, anti-clogging
Sulfur Recovery	Corrosive media, prone to condensation	Corrosion resistance, heating and insulation
Gas Separation	High-pressure gas, possible liquid content	Gas-liquid separation, pressure stabilization
Environmental Monitoring	Flue gas, emission gas	Dust removal, dehumidification, constant temperature

Product Advantages
