About 80 percent of energy use in industry is related to generation of heat. Green electrification of the heat demand is key to decarbonize the sector, respectively key to reducing Scope 1 (direct emissions) and Scope 2 (indirect emissions from purchased energy) emissions.
The electrification of industry is a complex puzzle. Electrification of Heat has a wide range of temperatures, from 80 °C to above 1000 °C for heating and/or for endothermic reacting. Furthermore, there are many different fluids like air, water / steam, olefins, thermal oil or molten salts, either as process fluid or heat transfer fluid. Finally, a variety of capacity sizes, from kilowatts to megawatts or even gigawatts have to be considered.
In NEMs presentation for AIChE last year, the main focus was on the different electrical heating technologies. During this presentation, NEM will share insight into:
1. Status update on the heating technologies developments at NEM
2. Basic principles of Thermal Energy Storage for energy arbitrage
3. Use - and business cases for Thermal Energy storage
NEM Energy is a globally renowned Dutch company interested to share its view on potential future solutions in the field of heat decarbonization. Developments are derived from their experience in heat transfer equipment for the power industry and large-scale industrial customers. This experience comes together with the late activities in Concentrated Solar Power (CSP) projects. NEMs focus is on medium and high temperature (200 °C to 1000 °C), beyond the reach of industrial heat pumps. And this is considered in combination with large-scale heating solutions in the 20 to 200 MW capacity range, in a single shell.

Since about 80 percent of energy use in industry is related to generation of heat, green electrification of the heat demand is key to decarbonize the sector. Respectively key to reducing Scope 1 (direct) and Scope 2 (indirect, from purchased energy) emissions.

During the presentation, insight will be shared into:
1. Electrification of heat principles and potential use cases,
2. Basic principle of Thermal Energy Storage for energy arbitrage,
3. Comparing three E-heater principles (resistive, inductive and radiative) and relevant design aspects.

The automation of industrial processes normally relies on two systems, a Basic Process Control System (BPCS) accessible to the operator and an independent Safety Instrumented System (SIS).
The Basic Process Control System (BPCS) is a system which handles process control and monitoring for a facility or piece of equipment. It takes inputs from process instrumentations or sensors to provide outputs based on design control strategy. The Basic Process Control System is responsible for maintaining the process parameters at optimum operating conditions within the required boundaries, therefore being also the first layer of protection against hazards.
The Safety Instrumented System (SIS) is designed according to IEC 61511:2016 standard to implement very specific Safety Instrumented Functions (SIF’s). A SIF is composed of one or more sensors, a logic solver and one or more final elements (e.g. pumps to stop or valves to close).
Sharing a sensor signal in BPCS and SIS is often seen as unacceptable in risk analysis studies, like Hazard and Operability (HAZOP) and Layer of Protection Analysis (LOPA). An innovative approach is proposed to quantify the level of protection provided by BPCS in conjunction to the classical SIL verification method. Any extra BPCS protection layer can offer risk reduction for the SIS. Without considering the safety contribution of the BPCS, the SIS system would be overdesigned resulting in extra cost.
As a case study, sharing three sensors between SIS and BPCS will be explained in more detail. SIS offers the possibility of using the same three sensors in 2 out of 3 (2oo3) voting configuration. BPCS is using the middle out of three (Moo3) value for more reliable process control and additional protection.
This study demonstrates that sharing BPCS and SIS instrumentation can improve both safety and controllability, increase the overall availability of the plant and reduce both CAPEX and OPEX.

Green hydrogen projects require high purity water. Egbert de Jong covers the production of ultrapure water from every quality of water that is available. This can be sea water, well water, river or surface water or treated wastewater. Technologies that are used comprise flotation or clarification, ultrafiltration, reverse osmosis and multi effect distillation and EDI or IX. The produced hydrogen product gas needs conditioning, for this the Veolia Deoxygenation and Dehydration solutions are presented. Cooling systems can benefit from Veolia services for chemical conditioning of cooling water. Water treatment processes can benefit from Veolia services for membrane protection. The above standard engineered solutions following robust proven supplier standards bring down the cost of hydrogen production.

Carbon Capture is necessary, in addition to Green H2, to limit the average temperature increase to a maximum of 1.5 °C in 2100, as agreed in the COP21 (Paris Agreement). The contribution of CCUS within all efforts to achieve this will be addressed. The ratio between CCS and CCU will be discussed with also the link to e‐Methanol, e‐Fuels and SAF within CCU, where the raw materials for the Fischer‐Tropsch reaction are Green H2 and CO2. The operation of a classic Amine Unit to capture CO2 with focus on the solvent chemistry will be outlined.
The different types of solvent with their advantages and disadvantages and how they 'degrade' over time will be addressed. Finally, the main topic will be presented. The reclaiming, and thus recovering / recycling, of the solvent via the ED reclaiming service, as offered by VWTS. This prevents the costly bleed and feed, which is not sustainable in comparison to the reduced CO2 footprint when applying
ED reclaiming.
