Descripción General:

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.

Descripción General:

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.

Industrias:
Descripción General:
  • Temperature monitoring at a tank farm
  • Temperature and pressure monitoring in tank jungles, three vertical monitoring points.
Industrias:
Descripción General:

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.

Industrias:
Descripción General:

In the event of a gas line shut down, gas supply must be maintained for a period of time with the use of LNG stored in road tankers. Each tanker must have its pressure monitored to prevent an over pressure situation arising.

Descripción General:

The client wanted to monitor the injection gas pressure of gas lift remotely in central control room. Antitheft measures are needed to install new equipments and cables.

Descripción General:

Remote leak detection for pipe line was needed to meet new environmental statute. However cabling earthwork is strictly restricted to protect land environment.

Descripción General:

Both bulk and finished inventories are stored in distributed tank farm remote from the site operations. These are difficult to instrument due to the infrastructure cost involved. These are then monitored daily by patrol rounds. While effective, this method does require a large skilled labor force to monitor all of tanks. This can impose an additional risk when the stored medium is of a hazardous nature.

Yokogawa Technical Report
Descripción General:

Wireless technology has a long history, and it began around the time that James C. Maxwell theoretically predicted and then proved the existence of electromagnetic waves in the 1860s, and when Heinrich R. Hertz experimentally confirmed the actual existence of the electromagnetic wave in 1888.

Yokogawa Technical Report
Descripción General:

In plant sites, there are various places such as those affording an unobstructed view like tank yards, and others surrounded by metal pipes and equipment obstructing the view (hereafter referred to "pipe jungles"), often seen in oil refinery and chemical on-site plants. The frequency band of radio waves used for field wireless communication is 2.4 GHz, which has high straightness and its ability to go around things can hardly be expected.

Yokogawa Technical Report
Descripción General:

As compared to Distributed Control Systems (DCS) such as CENTUM VP that monitors the operations of the overall plant, PRM is a type of Plant Asset Management (PAM) software package that primarily focuses on the maintenance of devices and instruments.

Yokogawa Technical Report
Descripción General:

The FieldMate versatile device management wizard is PC software mainly used for configuring and adjusting field devices. Under the concept of "one tool for all," Yokogawa has been enhancing this software to support a wide range of field devices and field communication protocols.

Yokogawa Technical Report
Descripción General:

In recent years, expectations for control systems using wireless communications have been increasing in the process control market. This is because these systems do not require power and communication wiring for field instruments, enabling reduced initial and maintenance costs, and easy installation.

Yokogawa Technical Report
Descripción General:

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.

Descripción General:

A distinguished panel comprising of CEOs, CIOs, CTOs and analysts, including CIO Review editorial board, has selected Yokogawa as one of the top companies that are at the forefront of tackling challenges in the wireless markets in the U.S.
