  • Process analytics optimizes crude gas processing for the production of fine chemicals at Lonza – Case Study

    Fine chemicals are used as active ingredients or additives in the pharmaceutical and food & beverages industries, as well as in agriculture. The cracking of raw materials such as light virgin naphtha or liquefied gas results in intermediate products (ethylene, hydrogen, methane, CO2). At the end of the process chain, these can provide highly pure materials such as niacin (vitamin B3) or ...

  • The Chemical Route to a Carbon Dioxide Neutral World

    Excessive CO2 emissions in the atmosphere from anthropogenic activity can be divided into point sources and diffuse sources. The capture of CO2 from flue gases of large industrial installations and its conversion into fuels and chemicals with fast catalytic processes seems technically possible. Some emerging technologies are already being demonstrated on an industrial scale. Others are still ...

  • Optimising laboratory environment for successful IVF

    The London Women’s Clinic in Cardiff (LWC Wales) is one of ten clinics within its group which collectively provide expert fertility treatment to families across England and Wales. When it comes to IVF and fertility treatment there is no ‘off-the-shelf’ or ‘one size fits all’ solution and, as such, the medical teams produce a bespoke fertility programme for each and ...

  • Sulfide emissions in sewer networks: focus on liquid to gas mass transfer coefficient

    H2S emission dynamics in sewers are conditioned by the mass transfer coefficient at the interface. This work aims at measuring the variation of the mass transfer coefficient with the hydraulic characteristics, with the objective of estimating H2S emission in gravity pipes, and collecting data to establish models independent of the system geometry. The ratio between the H2S and ...

  • What is Indoor Air Quality?

    Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...
