Heat pump technology development
Thread Content
This post was last edited by jiangfeng517 on 2016-10-6 at 22:14. I currently work as a process engineer in a chemical plant. Since the plant needed to install a set of class II lithium bromide absorption heat pumps, I was responsible for everything from the design and installation to the subsequent technical improvements; I thus gained a thorough understanding of the key aspects of this technology. Now, I would like to work together with knowledgeable individuals to carry out further research and development and make progress together. We can also optimize energy-saving processes for you. Note: This heat pump unit has a power of 10 MW, with annual benefits of over 7 million. Email: jiangf.jlsh@sinopec.com
In what situations is this type of pump mainly used? I haven’t seen it in any devices
May I ask where the company of the original poster is located, and what is the manner of cooperation?
I don’t understand; does the original poster want to provide technology or seek it?
It is mainly for energy savings, and it has become increasingly popular in the chemical industry. At present, its use is not widespread in China, but given the current pressures related to environmental protection and energy conservation, its prospects are very promising in the future.
My family is in Nanjing; I provide technical expertise.
Is this re-compression using steam machinery? I see that pump is also used in MVR systems
Similar, but that was an ancient machine; nowadays, many generations have been developed to save energy.
I posted a thread in another forum before; the original poster might be able to help clarify this issue: For a certain project, someone suggested using an MVR compressor. I haven’t worked with them before, so I would like to ask the experts here: 1. Is an MVR compressor suitable for saturated steam with mixed components (where the water content is greater than 80%)? 2. The compression ratio and temperature rise range of the MVR compressor: for a given compression ratio, how should the outlet temperature be chosen? Is being supersaturated advantageous, or is it necessary to cool down to the saturated state? 3. Does the presence of flammable organic gases such as methanol in the mixed steam affect the selection of the compressor? 4. Which manufacturers are available domestically or internationally? 5. Is there a flowchart for a similar system? 6. When using an MVR compressor, an MVR heat exchanger is usually also used. When a single MVR heat exchanger is not sufficient to handle the entire load, is it better to add an additional heat exchanger in parallel with the MVR heat exchanger or in series? That’s all I can think of for now; thank you everyone.
Have you calculated the economic benefits? It is driven by electricity; it’s probably not a heat pump, as heat pumps are mainly used for waste heat utilization, and the economic efficiency of using electricity in that context is too poor.
