Safety of chemical batch reactors and storage tanks

Concerns arise from the possible occurrence of pathogens in drinking water pipe biofilms and storage tank sediments. In these studies, biofilm samples from pipes and sediments from storage tanks of the Lisbon drinking water distribution system were analyzed. Protein determinations and heterotrophic counts on pipe biofilm samples were used to assess the Lisbon network sessile colonization intensity and distribution. Indicator and pathogenic microorganisms were analyzed in pipe biofilm samples, as well as in storage tanks biofilm and sediments, by using cultural methods and PCR, to assess risks. Results have shown that the Lisbon network sessile colonization is relatively weak in intensity. In addition, no meaningful hazards were apparent for both the network biofilm and the storage tanks biofilm and sediments.

And Storage

A number of LNG storage tank designs have been implemented on past and current projects. Such designs include full containment tanks with a 9%Ni inner liner for primary containment and storage of LNG at cryogenic temperature, a carbon steel liner for secondary liquid containment, thermal corner protection and vapor barriers on the inner tank and a concrete outer tank for resistance to external loads. LNG storage tanks are a key component of an LNG liquefaction or regasification facility and there is only a handful of specialized contractors that possess the tank technology and track record of the materials involved and the construction know how required for successful execution. This paper will focus on factors influencing LNG storage tanks design selection and construction execution strategies which can be a function of functional requirements as well as project location.
