New fl owmeters off er faster and more reliable data transmission for process industries


ABB has launched CoriolisMaster and ProcessMaster fl owmeters that can be powered over the same ethernet cable used for data transmission, eliminating the need for separate cabling. The new feature reduces installation time and cost, and increases the speed and reliability of data transmission.


One of the key challenges facing customers in process industries is the need to reduce the complexity and cost of installation and operations of fi eld instruments, infrastructure and systems. The new ABB CoriolisMaster and ProcessMaster fl owmeters featuring Profi Net with Power Over Ethernet address this challenge by providing a single-cable solution.


Profi Net is a protocol utilised in the fi eld of Operational Technology


(OT) that operates at the application layer. Incorporating Profi Net into ABB’s CoriolisMaster and ProcessMaster fl owmeters enables seamless and real-time exchange of data, and monitoring of alarms and diagnostics. It also allows for diverse confi gurations to ensure reliable and effi cient communication between the fl owmeters and across both local area and wide area networks (LAN & WAN).


“Remote monitoring and control are becoming increasingly important in many industries,” said Harald Grothey, Global Product Manager at ABB. “Profi Net’s high-speed communication capabilities with fast and reliable data transmission mean remote operators can make informed decisions in real-time, reducing the need to travel for on-site support. We are always looking for ways to help our customers become more effi cient. By reducing the need for separate cabling, the new CoriolisMaster and ProcessMaster fl owmeters are a stepping stone to a more resource-effi cient future.”


ABB’s CoriolisMaster and ProcessMaster with Profi Net ensure reliable data transmission by providing a stable and consistent power supply. This helps to reduce the risk of data transmission errors caused by power fl uctuations or interruptions and ensures that the data received by the control system is accurate and reliable. Transmitted in real time, information on fl ow rates and densities is always up-to-date.


The easy-to-access built-in webserver minimises time spent for set-up and parameterisation of the fl owmeters signifi cantly. Users get access to all parameters, such as measurement range, units, IO confi guration, verifi cation and diagnostic settings as well as a data-logging function. With this, a reduced overall commissioning and engineering time results in additional cost savings.

TALKING POINT


One of the prospects for circularity in the petrochemical sector is pyrolysis oil, an innovative substance enabling reduction in the use of virgin petroleum-based feedstocks. Harnessing this potential, however, requires a balancing act between technological innovation and governmental regulation that can either delay or facilitate this shift towards a more sustainable future. Pyrolysis, the science of decomposing substances at elevated temperatures in the absence of oxygen, has roots tracing back centuries but is currently going through a sort of renaissance as it holds the promise of turning plastic waste into synthetic gases, oils, and char residue, pioneering advancements in recycling methods.


Having decided that previous regulations for pyrolysis oils that fell under emissions standards were inadequate, the EPA has been toying with new statutes for pyrolysis oil components, attracting opposition from entities like the American Fuel & Petrochemical Manufacturers (AFPM). As the measures will potentially limit the use of the oils as feedstock for plastics, AFPM posit that restrictive propositions could hinder the United States’ progress in plastic circularity, leaving it trailing behind the international advancements in the sector. The accelerating plastic waste production, expected to triple by 2060, underscores the urgency to innovate and adopt advanced recycling techniques. The increasing dependency on plastics, juxtaposed with the mere 9% recycling rate, accentuates the environmental crisis and the necessity for innovations like pyrolysis. This comes at a time when governmental and industrial entities are considering alternative

However, these innovative recycling proposals are met with scepticism from environmentalists and some governmental sectors, arguing the potential detrimental environmental and health impacts of easing regulations on pyrolysis and gasifi cation. In particular, although it is known that pyrolysis oils can contain signifi cant levels of contaminants like metals, sulphur and chlorides, this contamination remains largely invisible to the American regulation regime. The EPA’s proposed rules aim to scrutinize chemicals made from plastic waste-derived feedstocks for unsafe contaminants before they are used for producing transportation fuels. Environmental advocates and community groups welcome the stringent regulations, viewing them as shields against the potential adverse impacts of chemical recycling expansion. The steadfastness on incineration regulation by the EPA provides legal tools for communities and environmentalists to contest against recycling plants employing pyrolysis or gasifi cation.


In the face of criticism, the chemical industry, supported by lobbying groups such as the American Chemistry Council, continues to champion advanced recycling, citing it as a pivotal move for scaling recycled material utilisation in products and promoting environmental sustainability. They have been instrumental in legal frameworks in several states, distinguishing advanced recycling as manufacturing rather than waste management, paving the way for more relaxed regulatory measures. The ongoing discourse surrounding advanced recycling methods, their regulatory paradigms, and

their potential environmental impacts is a refl ection of the complexities inherent in transitioning to a sustainable future. The innovation in recycling technologies like pyrolysis oil brings forth hope for addressing the growing plastic crisis. However, the proposed regulatory frameworks pose questions about their potential impact on the scalability and development of these technologies.


The need for collaboration between regulatory bodies, industries, environmental groups, and communities is paramount in sculpting a future where environmental conservation and technological advancement coexist, leading the way to a sustainable and circular economy. Balancing innovative advancements with environmental conservation requires nuanced understanding and considerate implementation of regulatory frameworks to ensure a harmonious journey towards sustainability.
