Environmental protection through greenhouse gases? Innovative CO2 technologies are able to reduce industrial emissions

From exhaust gas to raw material: intelligent technologies reduce emissions of carbon dioxide and give benefit to the environment and plant operators. Industrial activities are one of the largest generators of carbon dioxide (CO2) discharged as exhaust gas. Therefore, it is also considered as one of the biggest pollution factors.

Although one of the main objectives of the Paris climate agreement of 2015 is to reduce global greenhouse gas emissions, according to the International Energy Agency (IEA), emissions have increased since 2017. A development that will also be focused at this year's Earth Day on 22 April 2018. In particular, carbon dioxide can be recovered from industrial processes and recycled to be reduced in the atmosphere. This is an important advantage for the environment. But the industry also profits in various ways by recycling CO2 from exhaust gases.

Innovative Technologies prevent environmental impacts and economic losses

“The mere emission of CO2 in form of exhaust gas does not only pollute our atmosphere, it also loses cash,” says Corinne Ziege, Managing Director of CRYOTEC Anlagenbau GmbH, a subsidiary of EPC Group. The Wurzen-based company specialized in technical gases, has been planning and building plants for air separation and treatment of process exhaust gases since 1995. In particular, the demand for CRYOTEC’s CO2 technologies have increased considerably in the past years.

„There are two particular applications for carbon dioxide,“ Corinne Ziege explains. "First of all, it can be inserted directly into greenhouses. As a natural fertilizer, it considerably increases the profitability. Furthermore, CO2 can be reused as a raw material, as it is often the case in methanol production plants". The carbon dioxide is filtered out from the exhaust gas, cleaned in several steps and compressed. Depending on requirements, CO2 will either be recycled directly as a gas or after subsequent liquefaction. This is a great way for plant operators to save raw material costs while increasing the efficiency of plants and reducing greenhouse gas emissions. "Due to low operating costs and low maintenance requirements it is possible to reach a return on investment (ROI) after a short time," Corinne Ziege adds.

Dry Ice – coolant of the future

A further popular method for recycling CO2 is the production of dry ice. For the production, carbon dioxide is separated from the exhaust gas and then purified and liquefied. The liquid CO2 is then expanded to ambient pressure and partially evaporated. The energy required for evaporation is extracted from the liquid CO2, which leads to freezing and the final product: dry ice. The frozen CO2 is then pressed into block or pellet form and is ready for use.

Dry ice offers a wide range of applications within the food industry, e.g. refrigeration of fish, meat or beverages, for events and shows, whenever a fog effect is needed. Dry ice is also used for medical transportation of sensitive products such as organs or blood. In the industry it is used for cleaning of sensitive surfaces by dry ice blasting, for refrigeration of technical equipment and machinery and for metalworking. „Due to its extraordinary properties, dry ice offers a various range of applications,“ explains Managing Director Corinne Ziege. „Dry ice has a constant temperature of -78,5°C (-109,3°F). It doesn’t melt but evaporates residue-free. This is where the term “dry ice” comes from. Also, it is non-toxic, odor- and tasteless and prevents and even inhibits bacterial and fungal growth.”

Dry ice plants are also profitable for private investors

In comparison to the achievable profits from the sale of dry ice, the costs for the construction of a dry ice plant are moderate and can be amortized within three to five years. The requests for dry ice are rising continuously, as it has already established itself as the coolant of the future, thanks to its numerous positive properties. Therefore, also private investors are very interested in the construction of dry ice plants.



Two new plants in record time: CRYOTEC Anlagenbau GmbH to build two air separation plants in the Middle East

High-purity nitrogen in the shortest time: CRYOTEC Anlagenbau GmbH currently fulfils this wish of its long-standing customer Havayar. The company has ordered two plants for air separation and the production of gaseous and liquid nitrogen from the Wurzen-based plant manufacturer. Both plants will be delivered in less than 11 months, subsequently assembled on site and put into operation. As part of a larger petrochemical plant, they will then produce up to 1,950 kg/h of gaseous (N) and up to 375 kg/h of liquid (LIN) nitrogen.

"Our transportable, pre-assembled skids are tested right down to the terminal box mounted on the module," explains Corinne Ziege, Managing Director of CRYOTEC Anlagenbau in Wurzen. "This ensures fast and smooth installation and commissioning at the customer's site."


Disassembly of a Helium Filling Station: CRYOTEC Anlagenbau GmbH ensures smooth deconstruction in the shortest time

Relocation from Berlin to Krefeld: CRYOTEC Anlagenbau GmbH has been awarded a contract by Air Liquide Deutschland GmbH for the deconstruction of a filling plant for the re-liquefaction of helium. The Wurzen-based company is responsible for the disassembly of electrical switching units and dismantling of equipment components. CRYOTEC also provides the packaging and transport services, as well as the professional disposal of plant components and materials.

"The existing plant in Berlin has been completely dismantled. The main components will be used for the plant site in Krefeld," explains Corinne Ziege, Managing Director of CRYOTEC Anlagenbau GmbH in Wurzen. "Through our many years of experience in this segment and with special applications for technical gases, we were able to complete the disassembly of the helium filling plant for Air Liquide in Berlin within just a few weeks”.


Saxonian technology in the land of the Pharaohs: CRYOTEC Anlagenbau GmbH erects Nitrogen Generation Plant in Egypt

Tailor-made solutions from Saxony: CRYOTEC Anlagenbau GmbH delivers a compact nitrogen generating plant in Aswan, Egypt. The plant will be used for the production of high-purity gaseous and liquid nitrogen and is part of a fertilizer project for Egyptian Chemical Industries Company (KIMA). Contractor is the Italian plant construction company Tecnimont Private Ltd.

With a capacity of 600 Nm³/h, the customized plant will be put into operation in the second quarter of 2018. After a construction period of ten months in the in-house production halls of CRYOTEC Anlagenbau GmbH, the construction started on-site in Aswan in September 2017.
