Production issues of LNG from coke oven gas

Select the appropriate filter model and mesh size, and provide multiple spare filters. Pour it in with all your strength then.

Thank you to the friend who went upstairs; for now, we can only pour it, just pour it.

We originally designed it with a mesh size of around 200; it got clogged after just a few days. Now we’ve changed it to half at 100 mesh and half at 200 mesh, which should last for about two months. The key is to regularly regenerate the oil-removal tower used in the preliminary treatment process, in order to minimize the amount of oil present

The filter is only used at the start of operation; after running for a while, it can be removed

Coke oven gas does indeed contain a considerable amount of tiny liquid droplets and foam, as well as some dust and tar. At the inlet of the coke oven gas compressor, a separator must be installed to remove the tar droplets, water droplets, asphaltenes, and dust contained in the coke oven gas, thereby protecting the core compression equipment. Traditional compressor inlet separation devices, which are typically bypass filters, can easily become clogged with asphalt and solid dust, resulting in poor operational stability and pressure drop stability; therefore, the filter elements need to be replaced regularly. To ensure the continuous operation of the production line, it is also necessary to have backup separators as well as spare parts, resulting in high operating and maintenance costs. In recent years, high-efficiency vane-type demisting separators have been adopted in projects both domestically and internationally, gradually replacing the traditional mesh-type and filter-element-type gas-liquid demisting separators through technological upgrades. Compared to traditional barrier-type screen and filter element foam separators, the feather-leaf high-efficiency foam separator utilizes aerodynamic principles to combine various mechanisms such as efficient collision of fluid particles, coalescence and growth of liquid bubbles, vectorial separation of liquid droplets through swirl, and capture of free energy on the liquid film surface, thereby achieving a highly effective combined separation effect. Its internal components are less prone to clogging, it offers stable separation efficiency and operating pressure drops, has a long service life, low operation and maintenance costs, and is easy to operate; no backup separator is required. The feather-leaf blade type high-efficiency gas-liquid separator has been used to replace traditional mesh-type and filter element-type gas-liquid demisting separators. It has demonstrated very successful performance in over 80 projects in China, including high-efficient gas-liquid separation of the recycle gas in methanol synthesis plants, high-efficient gas-liquid separation in coal-to-oil Fischer-Tropsch synthesis plants, vapor-water separation in olefin processing, and vapor-water separation in ethylene oxidation and hydration processes for the production of ethylene glycol. Traditional industries such as coking should start by learning from new coal chemical enterprises, adopt this technology to upgrade existing equipment, improve the operational efficiency of these projects, reduce the costs associated with equipment operation and maintenance, and enhance the economic and social benefits of these projects. The technical core lies in the precision dynamics design calculation platform system and the separate component configuration for the corresponding internal structure; it is necessary to rely on foreign professional precision dynamics design calculation platform systems as well as professional separate component configurations for such internal structures. With professionally designed components from foreign platforms and patented internal parts manufactured in China according to those designs, such separators possess a strong technical and economic competitive advantage in domestic projects.

Thank you very much to the friend in post 7 for promoting this product; it serves two purposes at once – it answers the question and also introduces a new product. Could the friend on the 7th floor leave their contact information in a forum message so that they can get in touch with you?

Haha, the products from JORD are good quality, but they’re just too expensive

This is equipment designed by Novel Company on its own patented technology platform and manufactured in domestic factories to supply customers both at home and abroad; it offers an excellent cost-performance ratio； Our technologies and equipment are no longer promoted through the JORD platform. Engineering companies such as Fulu Engineering and Huafu Engineering have already utilized Novel’s patented technologies and products; their advantages in terms of performance and price outshine those of other domestic and international competitors. Both project owners and EPC contractors have given high praise to these technologies, committing to adopting them in future projects to upgrade traditional equipment. Please visit www.novelenergytech.com to learn about the patents it has applied for in China, as well as information on the dewaxers, shale gas separators, and methanol separators it manufactures and supplies in that country.

Luo Li, how much investment is required for this imported separator that you have introduced? Used at the inlet of the coke oven gas compressor; the pressure is approximately 3–5.8 KPa. It is required that the pressure difference across the separator not exceed 2 KPa, with a gas processing capacity of around 20,000 Nm3/h
