Measurement of High Temperature Gas in Ethylene Cracking Unit
Case: The ethylene cracking unit of a petrochemical plant needs to measure the flow rate of high-temperature cracking gas at 420 ℃, but traditional flow meters fail due to high temperature.
Solution: Adopt
split-typevortex flow meter(Sensor and transmitter separated), built-in vibration compensation algorithm, and customized nitrogen blowing interface to prevent sensor dust accumulation.
Effect: The measurement stability has been improved to ± 1.5% FS, and the annual maintenance cost has been reduced by 40%, ensuring accurate ratio of cracking reactants.
DMF (N, N-dimethylformamide) recovery measurement
Case: When recycling DMF in a chemical workshop, continuous distillation and precise flow measurement are required. The original flow meter has a low recovery rate due to corrosion and insufficient accuracy.
Solution: Choose Jiake Instrument JK-LUGB vortex flowmeter, use Hastelloy alloy material for corrosion resistance, and optimize signal stability through dynamic filtering algorithm.
Effect: The measurement error has been reduced from ± 3% to ± 0.8%, the recovery rate has been increased by 15%, and the annual cost of raw materials has been saved by over one million yuan.
Torch gas emission monitoring
Case: The flare gas emission flow rate in a refinery fluctuates greatly, requiring a wide range ratio instrument to adapt to low flow rate to high flow rate conditions.
Solution: Install an anti vibration vortex flowmeter (with a range ratio of 1:20), equipped with temperature and pressure compensation function to directly output mass flow rate.
Effect: Real time monitoring of emissions, avoiding environmental penalties, while optimizing combustion efficiency, reducing gas waste by 20% annually.
