A new technology for manufacturing of cryogenic storage tanks for high-purity monosilane
As a specialist for generation/storage/distribution of high-purity technical gases, Cryotec Anlagenbau is currently delivering a plant for storage and evaporation of high-purity monosilane.
For such a special product with very high purity requirements, new technologies for manufacturing of cryogenic storage tanks have been developed.
This is another proof for Cryotec´s outstanding success in high-requirement technical gas plant business.
A plant for purification/liquefaction of CO2 for Kenia
After only 4 months of manufacturing, Cryotec Anlagenbau GmbH Wurzen delivers a plant for purification/liquefaction of CO2 from a natural source to Kenia, for food industry consumption. The plant will be started-up and commissioned in CW 3/2010 on site in Kenia, by specialists of Cryotec Anlagenbau GmbH.
"Cryotec: Efficient use of existing and access to alternative ressources Future-oriented Plant Construction" News from KI Kälte-Luft-Klimatechnik of Sept. 2009
Nowadays, when the news are reporting about environmental protection issues, they mostly refer to global greenhouse effect, finiteness of the fossil energy sources, improvement of power efficiency and the separation of carbon dioxide in power generation. Just as much, the news are reporting about alternative power generation by photovoltaics or large-scale energy management projects for reduction of the dependency of single consumer or transit countries regarding the supply with fossil energy resources. Less attention is drawn to issues that are part or supplement of such large-scale projects, by using new technologies and processes, that are in itself a way of environmental protection in combination with an improvement of the actual process, regarding yield and/or quality.
As a specialist in the generation and processing of technical gases, Cryotec Anlagenbau GmbH Wurzen is actively contributing to a more efficient usage of existing or development and usage of alternative resources. The plant equipment of small and medium-sized capacities, often tailor-made to the respective customers´ requirements and often extreme outside conditions, can be divided into the following sections:
- Plants for generation of gaseous or liquid nitrogen, oxygen and argon
- Plants for generation / separation and processing of carbon dioxide
- Plants for processing of natural gas (NG, CNG, LNG, LPG)
- Plants for processing and treatment of natural gas-like gases (e.g. biogas,
flare gases, carrier gases)
- Plants for special gases (e.g. Acetylene, Monosilane).
In order to solve the occurring problems and to meet the respective specifications, the typical processes of cryogenics, thermal and chemical process technologies as well as own, special developments and layouts are applied. The basis of the special solutions is the required know-how that has been initially accumulated in the times of MAFA Wurzen company, which was a well-known compressor and plant equipment manufacturer in the former German Democratic Republic. Constantly and steadily, the know-how has been intensified, expanded and adapted to the actual state of technology, also by performing R&D projects in close cooperation with various R&D facilities and institutions.
As process proprietor and contact partner for all stages of a project, Cryotec guarantees a high level of quality and customer satisfaction, by manufacturing specialized components or developing special software solutions. Since the beginning of this year, Cryotec can rely on even more engineering potential, because it has been integrated as a new member into EPC Group, a successful medium-sized industrial plant construction company group.
Carbon Dioxide for East Africa.
A fact that is hardly known in today´s Europe and barely imaginable considering ecological issues is the carbon dioxide generation process in economically underdeveloped regions, e.g. the greater part of Africa. The currently widely-used process for this is the combustion of fossil energy sources and the subsequent elution and purification of the carbon dioxide from the offgas. But the produced heat can only be used to some extent in the process and is normally abjected afterwards.
An alternative way to the existing technology and for reduction of the used primary energy is the usage of natural gas resources with high carbon dioxide percentage. Such a plant – currently already being operated in Kenia – consists of the following process stages for the processing of the gas. At first, the raw gas is being filtered and eluted in a pre-purification unit. After the subsequent compression to process pressure, the sulfur compounds are completely removed from the gas and oxidizable substances, e. g. hydrocarbons, are catalytically oxidized in a reactor under increased pressure conditions. The pre-converted gas is dried, existing essences and smells are removed and inert gases are being separated after the liquefaction at approx. – 30°C in a stripper. The gas is being stored and transported in cold and liquid form. The demand on food-grade quality carbon dioxide has been increased so much that the owner of the plant is considering the expense of another plant.
Nitrogen and Oxygen for petrochemical industry.
Currently, the petrochemical industry is undergoing a drastic change, because of the shortage of the resources. Resources that have not been worth using from the economical point of view are being tapped into and extraction and processing equipment is being modified to comply with the new, changed conditions. Mostly, the increased product quality and the safety in extraction and processing require the usage of high-purity nitrogen and oxygen, sometimes in considerable quantities. Another demand arises during necessary maintenance and repair work. A possibility to produce such quantities in the required purities are air separation plants, based on the process of cryogenic rectification. With the right design, such plants offer the possibility of producing high-purity, cryogenic, liquefied gases, apart from the supply of gaseous products, especially when it comes to nitrogen, oxygen and argon. Combined with cryogenic evaporators, a peak load can be covered or a emergency buffer in case of a shutdown or critical situation can be provided.
Other applications for the usage of liquefied gases are the supply of external large-scale consumers or satellite stations as well as the filling of high-pressure vessels by pressure increasing cryogenic pumps, subsequent evaporation/warming-up and filling.
Modern, compact, future-oriented.
All plants and processes are constantly improved and tailor-made to customers requirements, not only considering the product parameters. The usual plant is a compact skid-mounted or containerized component, in order to reach a high grade of prefabrication and to reduce the required space for the plant unit itself and its assembling onsite. Such equipment provides a remote operation as well as the support of the operator personnel. Apart from the well-established processes and their modification, new market opportunities are seized, e.g. in biogas technology or the processing of flare/carrier gases.
“CRYOTEC grows“ Sachsenspiegel of 3rd of July, 2009
Contrary to the actual trend, CRYOTEC Anlagenbau GmbH grows. The most recent order comes from Cuba.
For the second largest city of this country, CRYOTEC supplies the equipment for a CO2-recovery system of a brewery. The offgas will be recovered and re-used in the beer production process.
Currently, the versatile company is cooperating closely with the Technical University of Dresden to develop an innovative natural gas extraction process. It is a unique development process for liquefaction of natural gas with a high CO2-ratio, from smaller, previously unused natural gas resources.
For the next 12 months, two gas separation systems will be delivered to Iraq. The order books are full up to the end of the year 2010.
