Petrochemical and Chemical Application Notes Index
|
 |
Liquid Analyzers for Electrolysis Plants |
|
Process liquid analyzers such as pH meters, conductivity meters, ORP meters, and density meters play an important role at electrolysis plants in the control of concentrations of various process solutions.
|
|
|
Integration of Real-time Utility Monitoring with a DCS |
|
The discharge of improperly treated industrial chemicals and fuel gas can have a major impact on the environment, posing a serious threat to public health. Concurrent with the global growth of manufacturing operations to keep pace with market trends, many countries are taking measures to deal with environmental problems.
|
|
|
Maintaining High Quality in Soda Electrolysis |
|
Caustic soda is an important basic material in the chemical industry and is mainly produced
by the electrolysis of soda. In the electrolysis process to make concentrated caustic soda, the
DM8 Liquid Density Meter ensures high product quality through accurate measurement of liquid density.
|
|
|
Humidity Measurement in Dyeing and Discharge Processes |
|
To ensure stable product quality, humidity in the steamer is kept at a constant level. The ZR402G/HS Direct In Situ Zirconia High Temperature Humidity Analyzer provides excellent maintainability and ensures stable measurement in high temperature environments.
|
|
|
Measuring the Electric Conductivity by CIP System |
|
CIP is the system designed for automatic cleaning
and disinfecting. Our ISC202 conductivity transmitter has earned a reputation in the recovery of cleaning solutions because it can
take measurements with good boundary surface precision over
a wide range.
|
|
|
pH Measurement in Limestone-Gypsum Flue Desulfurization |
|
In limestone-gypsum flue gas desulfurization systems, the
consumption of a desulfurization agent (lime) is controlled using
online pH meters. The EXA AUTO CLEAN chemical cleaning system achieves cost effective and accurate pH measurement.
|
|
|
pH Measurement in Flue Gas Desulfurization Systems |
|
| The EXA AUTO CLEAN chemical cleaning system automates
the acid cleaning process, which not only saves both time and expense but also ensures precise pH measurement over long periods.
|
|
|
Measurement of Supersaturated NaCl Concentration |
|
NaCl concentration at a salt dissolver is highly important because of the electrolysis efficiency. The ISC202 inductive conductivity meter provides concentration reading and improves substantial maintainability, cost performance and measurement accuracy.
|
|
|
Impulse Line Blocking Diagnosis |
|
Operators must receive diagnostic information before a line block leads
to a malfunction. Yokogawa provides predictive diagnostics based on
trend analysis of the blocking factor, which improves maintenance
efficiency and reduces maintenance costs.
|
|
|
Oil Heater Average Value Control |
|
The CX1000/CX2000 offers an average value computation function making it ideal for controlling temperature and other fluctuating phenomena. The operating status can be controlled in real time, providing operating cost reductions.
|
|
|
Measurement in Cogeneration and Captive Power Boiler |
|
Steam is still one of the most popular methods of providing an energy source to a process and its associated operations. The more accurate and reliable measurements that are made, the more informed decisions can be taken that affect costs and product quality.
|
|
|
Cryogenic Gas Transfer System |
|
The accurate flow measurement of liquefied gas by employing an all-digital FOUNDATION fieldbus™ based
communication approach along with cryogenic gas
dispensing controls.
|
|
|
Flue Gas Desulfurization |
|
Wet flue gas desulfurization or scrubber systems are an excellent way of reducing the sulfur dioxide emissions caused by coal combustion boilers.
|
|
|
Autolevel |
|
Level transmitter configuration can be very time consuming.
DPharp transmitters with advanced software functionality
eliminate this time consuming task. With maintenance shops
getting smaller, finding equipment that allows us to do more with
less becomes a priority.
|
|
|
Low Flow Cut-off |
|
One of the most common applications for differential pressure
transmitters is flow measurement. DPharp differential pressure transmitters have some unique signal conditioning features to eliminate instability at low flow rates.
