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.

Preventing Fugitive Emissions with Vortex Flowmeters |
|
The oil refining industry today faces increasingly strict regulations that dictate both the quality of its products and the
diligence of its production processes. As the pioneer of the vortex flowmeter technology, Yokogawa's challenge in bringing innovative flow measurement solutions to users in various process industries continues to this day.

Top Gas Density Measurement in a Fluid Catalytic Cracker |
|
The top gas generated at the top of a distillation column in a petroleum refinery's fluid catalytic cracker (FCC) is used to produce gasoline and LPG. The GD402 Gas Density Meter features an intrinsically safe and explosion-proof design, fast response, and a dust-proof, anti-corrosive, and flame-proof construction.

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.

|
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.
|
|
|
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.
