Turnbull & Scott supports customer journeys to Net Zero

urnbull & Scott is increasingly involved in supporting customers across many industries on their journeys to Net Zero. It’s a role taken seriously with pride and like everyone, they’ve had to learn a new Net Zero language but in doing so have found it has helped them to contextualise how they ‘fit in’ on their customers’ journeys.
Helping reduce ‘Scope 1’ emissions - Working directly with end-users, with Energy Service Companies (ESCos) and EPC contractors their work largely relates to helping industrial customers reduce their ‘Scope 1’ emissions (direct emissions from owned or controlled sources) as categorised within the Greenhouse Gas (GHG) Protocol. The GHG Protocol is the most widely used international emissions accounting tool which, by dividing emissions into three groups, intends to help measure progress in making the huge reductions that are needed to limit global temperature rises to well below 2°C - the central aim of the Paris Agreement. For the benefit of those keen to improve their language skills too:
Scope 1 covers direct emissions from owned or controlled sources. Scope 2 covers indirect emissions from the generation of purchased electricity, steam, heating and cooling consumed by the reporting company. Scope 3 includes all other indirect emissions that occur in a company’s value chain.
Energy Conservation Measures (ECMs) - A major part in reducing Scope 1 emissions for any business is to work on Energy Conservation Measures (ECMs). These are simply any measures that can be taken within the business to reduce energy consumption (and cost) by a particular process technology or facility. Companies that have embarked on the Net Zero journey will undoubtedly have drawn up a wide-ranging list of projects from simple lighting upgrades, motor upgrades, reduction of compressed air pressure to major heat recovery projects such as capturing waste heat from dryer flues, kiln flues, boiler flues, compressors, chillers, ORC cooling loops to effluent streams. These heat recovery projects fall directly into our scope of supply.

Spotlight on reducing gas consumption in process air heating - An area Turnbull & Scott has been increasingly involved in is the design and supply of heat exchanger coils for the pre-heating of process air. As part of a Net Zero journey some customers have already invested in biomass boilers to produce low-carbon steam or hot water and some have invested in heat pumps to boost the
temperature of waste heat. When it comes to making use of newly available heat sources in critical processes however, there can be an understandable nervousness amongst process owners. With Turnbull & Scott’s strong track record in heat transfer projects, MD Peter Murphy finds himself immersed in carbon and energy reduction projects as well as the new Net Zero language and is often involved with ESCos and end users at the concept design stage. To engender some confidence among process owners across industries contemplating
Deublin focuses on operating costs with Paper Energy Optimisation
aper mills consume a significant amount of thermal and electrical energy with thermal energy used mostly to dry paper by way of steam. The dryer section is the highest thermal energy consumer on the paper machine, accounting for two-thirds of total energy use. Increasing energy costs and price volatility are challenging the profitability of most paper mills. Therefore, companies must invest in ways to manage energy consumption efficiently. A

proper optimisation programme can help companies cut operating costs and increase profitability. In addition, dryer section performance has a major effect on production rates, energy efficiency and sheet quality, making efficient use of energy an integral part of good paper mill operation. Therefore, a proper steam joint and steam & condensate system design should minimise energy consumption in the drying process and contribute to higher production efficiency.

Deublin is introducing the Paper Energy Optimisation (PEO) programme to support the paper industry in elevating its profitability. The company provides solutions that increase paper equipment efficiency, decrease energy consumption and increase productivity with complete steam systems, dryer optimisation services and components worldwide. PEO can find the root causes of inefficiency and help mills lower operating costs.

transitioning away from 100% natural gas usage in process air heating, he shares a notable success: “What we observe is working well is the partial use of such low-carbon heat in critical processes. For example in the malting industry, where 1 ton of malt takes 750kWh gas plus 150kWh electricity to produce, there is a concerted effort to reduce gas consumption. What is now in the comfort zone for these process owners is using low carbon generated steam or hot water to pre-heat incoming air on entry to the kilns. This is done by running steam or hot water, produced by biomass boilers, through steam-air or water-air heat exchanger coils resulting in natural gas savings of at least 30%. Similarly, there are examples where the hot water for the coils is supplied by a heat pump system linked to a waste heat source.”
