Successful Project: Improving Environmental Performance in Power Plants

Steel, power generation, and other heavy industries are among China’s key industrial sectors. However, these industries often generate significant waste byproducts, such as flue gas and wastewater, leading to environmental challenges. To address these issues, these sectors are gradually adopting cleaner production methods. One critical measure is the installation of flue gas desulfurization and denitrification systems to reduce harmful emissions.

• 1. Project Background

A power plant in China uses limestone slurry as a desulfurization agent. The slurry reacts with sulfur dioxide in flue gas to produce gypsum or calcium sulfate, effectively purifying the gas and controlling emissions.

Monitoring the density (or concentration) of the limestone slurry is essential to ensure the proper amount of desulfurization agent is added during the process. Accurate dosing is key to achieving optimal desulfurization efficiency and maintaining the stability of the equipment.

• 2. Client Requirements

Adapt to the specific on-site process conditions (e.g., gypsum or calcium sulfate precipitates after the reaction) without causing pipeline blockages.

Enable precise measurement of limestone slurry density (concentration).

Deliver high accuracy and repeatability to maintain consistent product quality.

• 3. Our Solution

In this case, density is a crucial parameter that directly impacts the efficiency of the desulfurization reaction and the overall performance of the flue gas treatment system. Based on the client’s requirements, we recommended our straight-tube Coriolis mass flowmeter series to achieve precise measurements of the limestone slurry density.

• 4. Key Features of Our Solution:

Straight-Tube Design: Compared to traditional U-shaped (microbend) designs, the straight-tube Coriolis flowmeter minimizes residue buildup, effectively preventing the pipeline blockage the client was concerned about.

Advanced Digital High-Frequency Technology: Enhanced measurement precision ensures accurate monitoring of the limestone slurry density, improving the efficiency of the desulfurization process.

• 5. Achieved Results

With the Coriolis mass flowmeter, we successfully enabled the power plant operators to better control the limestone slurry density. This improvement boosted the desulfurization reaction’s efficiency and enhanced the overall performance of the flue gas treatment system.

Kaifeng Oasis Instrument Co., Ltd. has manufactured and supplied many straight-tube Coriolis mass flowmeters for numerous industries, including steel, power generation, metallurgy, and environmental protection.
