Currently, I am following up on the sampling renovation of an acetic acid factory. The Swagelok three-way valve + needle valve + drainpipe type sampling valve is used on site. It has a simple structure and simple operation. It seems very convenient and environmentally friendly, but in fact it is not. Vinyl acetate is easy to polymerize. This causes the dead zone of the outlet section of the three-way valve to form a blockage. In addition, the VOC test exceeds the standard. Nowadays, chemical plants have very strict requirements, and LDAR tests are performed regularly. Currently, the sampling points in the entire plant are set as key testing objects. This causes great trouble to the site, so the factory director is determined to transform the sampling system. ； The name of the factory is kept confidential for the time being. It is a joint venture between a world-renowned acetic acid manufacturer and a local enterprise. It has many sampling points. ； You can learn about the Swiss BIAR online closed sampling valve/sampler/sampling system, which has no dead zone, no residue, reduces VOC emissions, and there is no problem with LDAR detection. ； Suitable for liquid sampling, phenol, caprolactam, nylon 66, acrylonitrile, PVC chlor-alkali plant, paints and coatings, vinyl acetate, BASF special chemicals, Yantai Wanhua MDI TDI, ethylene glycol, BDO project liquid sampling, VCM liquid sampling, bisphenol A, etc. ； To request information, please contact * etan * u@163.com WeChat ID: * etan * u2014
