Smart Pressure Transmitter Application in Organic Pigment Workshop

Background

The organic pigment manufacturing industry has a long history and is an important branch of the fine chemical industry. As insoluble organic matter, organic pigments are rich in color and have high tinting power. They can be widely used in various industries such as coatings, plastics, inks, electronics, and papermaking.

The global demand for organic pigments is about 400,000 tons, of which high-performance organic pigments account for about 80,000 tons. China's organic pigments industry has a total output of about 300,000 tons, accounting for 75% of global production, thus making it the largest producer and exporter of organic pigments worldwide. With the continuous improvement of environmental protection technology, the improvement of the international trade environment, and the continuous development of downstream industries in the future, China's organic pigment market will continue to maintain steady development.

Overview

However, in traditional production workshops, workers stand on three-tier platforms to manually feed materials to the vessel. Due to differences in the technical level and experience of operators, it is easy to cause problems such as inaccurate feeding, confusion, dust, and poor product consistency. There are also instances of exposure to high-temperature steam, which poses health risks to workers. With the high-quality development of the pigment industry and the continuous improvement of customer requirements for product quality, organic pigment manufacturers have begun to upgrade and transform their operations.

During the smart transformation of the workshop, smart pressure transmitters can accurately monitor and control the levels in various raw material and finished product storage tanks, the pressure at the top of reaction vessels, and the gas pressure in pipelines. They interact with the automated control system of the production line to adjust and control specifications in real-time, ensuring stable operation and enhancing production efficiency and product quality.

Solutions

Solution 1: Pressure Measurement of Dryer Exhaust

• Measuring Environment: Medium gas phase temperature of 200°C, ambient temperature of 60°C, pressure range of -1 bar to 6 bar.

• Application Products: MICROSENSOR MDM7000-GP/DGP/GP-T Smart Pressure Transmitter

• Introduction: The pressure transmitters have China intrinsically safe and flameproof certificates, international ATEX, IECEx, EAC and other certificates. For high temperature and high vacuum conditions, remote capillary, high temperature heat sink and ultra-high temperature flange port are available. The heat sink is available for this condition, which is suitable for the medium temperature of -40~150℃ and can achieve stable pressure measurement in high temperature conditions.

Solution 2: Level Measurement of Filter Press

• Measurement Environment: Process medium is acidic water, with a temperature of 70°C-80°C and a pressure range of 0 to 1 bar.

• Application Product: MICROSENSOR MDM7000-LT Smart Pressure Transmitter

• Introduction: The smart pressure transmitter features a fully welded diaphragm seal system, with diaphragm materials including 316L, HC-276, HC-22, Monel 400, Ta, Ti, Duplex 2205, 904L, and ZR. The processing options include gold plating, PTFE spraying, diamond coating, and PFA cover, ensuring excellent corrosion resistance. For this condition, the tantalum diaphragm is available for its exceptional corrosion resistance, making it suitable for hydrochloric acid and concentrated nitric acid. Choosing the appropriate diaphragm material can effectively enhance the transmitter's service life.
