Transdyn provides systems and services to design, supply, and commission supervisory control and data acquisition and pipeline automation systems for the distribution and storage of petroleum products and natural gas. We work closely with public and private utilities to provide open, reliable, efficient, and scalable control and information management systems for their distribution networks. We recently partnered with Hong Kong and China Gas to design and build one of the world’s largest natural gas pipeline management systems that serves over 85% of Hong Kong’s households.

System Description: The Hong Kong and China Gas Company Limited (also known as Towngas) is committed to providing safe and clean fuel to the people of Hong Kong. Founded in 1862, Towngas is the oldest public utility in Hong Kong, and the first gas utility in the Far East. Today, Towngas is a listed corporation whose business mainly comprises the production and distribution of gas, marketing of gas and appliances, and the supply of towngas and related services to 1.4 million households and businesses in Hong Kong.
Transdyn was selected to design, supply and commission a third generation DYNAC® SCADA system for the Hong Kong and China Gas Company Limited. Transdyn provided the existing DYNAC® SCADA (Supervisory Control And Data Acquisition System) originally commissioned in 1994. The DYNAC® SCADA software, which runs on a fully redundant master station, will monitor and control the distribution of towngas throughout Hong Kong via remote terminal units (RTUs) and PLCs from several vendors. Communications are provided by leased telephone lines and a wide area network (WAN).

System Description: The Chevron Research and Technology facility at Point Richmond,
California developments and improvemes processes for the refining
of petroleum products. The research is performed at the facility in
batch process “pilot plants”, the main purpose of which is to test the
properties of various catalysts and other components used in the
refining process.
The test materials are pumped through a series of reactor furnaces,
and the resulting material is extracted at the end and evaluated.
The information derived from this research helps Chevron improve
the petroleum refining process and make better use of raw materials.
Transdyn provided project management and engineering,
applications programming, testing, training and start-up services for
over a dozen systems, with each system controlling up to 4 pilot
plants. The pilot plant control systems installed by Transdyn utilizes
Allen-Bradley ControlLogix, each interfacing with a workstation
running Wonderware’s InTouch HMI software.
The pilot plant control logic includes Temperature Zone monitoring,
Temperature Zone control, Pressure and Flow control, and a multistep
“Ramp-Soak” profile for temperature control in the reactors.
Another feature of the control logic is a Power Fail delay, which
allows the operator to define the length of time that a pilot plant
power outage could last without affecting the outcome of an
experiment.
Other control features include an interface with a gas
chromatograph, which samples and analyzes the materials in
process, and calculates automatic temperature setpoints for the
reactors. The control systems also interface with weigh scales, used
in the process to measure the amount of test material used during
the batch tests.
