Refining is a game of thermal dynamics and pressure management. Within the cracking units and distillation towers, instrumentation is the only thing standing between operational profit and catastrophic failure. The presence of hydrogen at high temperatures, combined with sulfur and heavy crudes, creates one of the most corrosive and volatile environments in modern industry.
At YunRui, we specialize in the “Severe Service” category. We understand that in a refinery, an instrument’s reliability is measured by its resistance to drift and its ability to withstand 24/7 thermal cycling. We supply the instrumentation that powers your critical control loops, ensuring that your facility meets its production targets without compromising on safety or environmental standards.
Refining Solutions
High-Temperature & High-Pressure Monitoring
Monitoring the vacuum distillation unit or the coker requires sensors that won’t fail under heat. We provide Pressure Transmitters with remote capillary seals and specialized fill fluids designed for temperatures exceeding 300°C. These systems are essential for maintaining the pressure gradients required to separate heavy crudes into high-value fuels.
Critical Thermal Profiling
In catalytic cracking and hydrotreating, the temperature profile determines the quality of the final product. Our Temperature Transmitters offer the high-accuracy cold-junction compensation and dual-sensor input reliability required for these mission-critical reactions. YunRui ensures your control room has the real-time data needed to prevent “hot spots” and optimize catalyst life.
Mass Balance & Precision Flow
Managing the flow of feedstocks and finished products requires custody-transfer levels of accuracy. Our Flow Transmitters—including multivariable and differential pressure models—are engineered to handle the varying viscosities of refined oils. We help refineries minimize “mass balance” discrepancies and ensure efficient movement through the tank farm.
Why Choose YunRui
Severe Service Expertise: We offer instruments with Alloy 400 (Monel), Gold-plated diaphragms (for hydrogen service), and specialized coatings to prevent hydrogen permeation.
