MAN to supply compressor technology for Chinese synthetic fuels project

The site of the project is Yinchuan in the Ningxia region, where air separation plants are being built under the management of Linde and Hangyang for one of the world’s largest coal liquefaction production plants. The turbomachinery ordered will be used in one of the air separation plants.

High-pressure polyethylene: Reemergence as a specialty chemical or not?

The analysis results indicate that, while investment capital for new plants favors LLDPE, plant profitability—which is a function of product slate (revenue) and cost—is, in many cases, higher for LDPE plants.
