Air Supply Measurement for Reactors

Introduction

A chemical company used variable area flowmeters to measure air flow as a key component to their reactors. In reviewing the technology, and aging variable area flow meters, the client identified with inaccurate flow measurements due to the fact that the VA meters could fluctuate up to 10% with seasonal air temperature cycles. The quality of the product is impacted significantly when air flow volume is higher or lower than required for process conditions.
Therefore, the client decided to replace the aged VA flowmeters for further improvement of product quality with vortex flowmeters with temperature compensation function.

Proposal

The digitalYEWFLO vortex flowmeter multi-variable (MV) type is suitable for this process due to the following reasons.

  1. Individual thermometer is not necessary for temperature compensation. A temperature sensor is built into the digitalYEWFLO/MV.
  2. Temperature compensation function is running in digitalYEWFLO/MV. Compensated flow process volume is sent to the host control system.
  3. Existing 2-wire communication cable can be used. No additional cabling is required.

Field data

The digitalYEWFLO vortex flowmeter MV type enables more accurate control of supplied air volume to the reactors due to built in temperature compensation. Productivity improvement achieved through enhanced flow measurement with digitalYEWFLO MV technology.

Advantage

Wiring and Installation : Multi-variable (MV) type digitalYEWFLO installation is cost effective when replacing the 2-wired flowmeter. Comparative 4-wire mass flowmeters require new installation of wiring. MV type digitalYEWFLO reduces the installation cost by approx. 25%, compared to other mass flowmeter solutions. It delivers time savings as well.
Below graph reflects typical cost of digitalYEWFLOW vs mass flowmeter installation.

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
