Continuous technology improvement is ongoing in the pulp & paper industry to obtain the best possible performance. The improved plant performance translates to the higher quality improvement and lower cost, and simultaneously environmental friendly plant operation.
Employ the ISA100.11a-compliant YTMX580 Multipoint Wireless Transmitter. The YTMX580 has 8 channels of universal input, which is perfect for multipoint measurement applications, and it can withstand harsh operating temperatures of -40 to 85 °C.
A battery room is used to storage batteries for emergency power management in the plant. Each substation has battery room and the storage batteries are lead-acid batteries which must be maintained within specified operating temperature limits. Temperature management is important to ensure a long service life of the batteries especially for the plant in desert climates.
Delayed Coker is a type of coker who's process consists of heating residual oil feed to its thermal cracking temperature in a furnace. The most important variable in industrial furnace control is temperature. Temperature is measured throughout the furnace in different zones and temperature effects the materials being manufactured and therefore must be precisely monitored to prevent deviations in quality of the final product.
Blending plays a key role in industries such as food, healthcare and chemicals etc. Temperature and vacuum measurements are very important in minimizing the moisture content to ensure the quality of the final product. Strictly maintaining them throughout the process ensures the final product yield.
Geothermal power plants create electricity from geothermal energy. These power plants are similar to other steam turbine station; however their heat source is that of the earth's core. The created steam is used to turn the turbine for the production of electricity. Technologies include Dry steam, Flash steam and Binary cycle power stations with Binary cycle being the most common geothermal plant in current production. In the process of geothermal power generation the facility needs to monitor various processes, as in this case steam line pressure sits in remote from control room's location.
A horizontal rotary miller used to grind the limestone rocks with metallic balls as grinding stones. This is used as the raw ingredient to produce cement powder. The temperature needs to be monitored in order to control the process and the quality of the final product. The user was using an induction temperature measurement based on a rail system that was very fragile and therefore unreliable.
Temperature plays a key role in storage of Molasses to maintain the chemical properties of molasses. When temperature rises over 40.5 degree C, destruction of structure in sugar occurs, which results in losing the feeding property of molasses. There is also a safety concern that a rise in temperature can lead to a rise in storage tank pressure leading to an explosion of the tank.
Direct Reduction Iron (DRI) is one of the processes to reduce oxygen from iron oxide pellets for steel plant. More than 90% of DRI processes use heated LNG as process gas where PID control for temperature or interlock control is of vital importance.
One important risk to manage with regard to coal stacks is preventing fires due to spontaneous combustion.
In recent years, more field wireless devices have been used in hazardous areas. Meanwhile, in plants that are usually recognized as hazardous areas, there are numerous metallic tanks and pipes that easily shield or reflect radio waves, as discussed later, thus resulting in a poor environment for wireless communication.
The innovation of wireless technology increases the use of wireless communication in the industry. The introduction of wireless communication to plants, however, requires strict features such as robustness, real-time responsiveness, and low power consumption. This has restricted the use of wireless communication to limited applications such as data logging and device status monitoring that does not require strict real-time responsiveness and data arrival reliability in communication.
