On-site production of chemicals

The current efficiency of Traube s method was pushed to 92% [94] with the introduction of pressurized electrolysis. In 1939, Rubio [93] developed another process for producing H202 by the reduction of 02 in 50% KOH using an active carbon cathode and a Ni anode, with no industrial success. Today, most H202 are produced chemically by the anthraquinone process, which is unsuitable for small-scale production [91]. Another electrochemical process involving 02 reduction on carbon-based cathodes developed by Dow Chemical [2,95] has found a marketplace for on-site production of alkaline H202 for pulp bleaching. 

Direct requirements for acquisition are found in Federal Acquisition Regulations (FAR) and Department of Energy Acquisition Regulations (DEAR). In addition, there are many regulations and standards that include implied requirements for the acquisition of chemicals and chemical products. Therefore, implied requirements are summarized here but are not included as mandatory requirements in this chapter. Requirements for on-site transportation of chemicals and chemical products can be found in Chapter 4 of this document. 

This chapter identifies and consolidates existing user safety and health requirements found in DOE and other federal chemical-related safety and health regulations and national standards (especially those of the Compressed Gas Association (CGA)) applicable to all locations involved in the on-site transport of chemicals and chemical products (see def.). This includes hazardous materials offered for transportation on-site, and the packaging, labeling, or marking of hazardous materials for transportation on-site. State and local codes and requirements are not included. 

Guidelines to determine the usability of chemical weapons produced between 1925 and 1946, in accordance with Part IV (B), paragraph 5, of the Verification Annex Guidelines for determining the frequency of systematic on-site inspections of chemical weapons production facilities, in accordance with Part V, paragraph 54, of the Verification Annex ... 

The cost of transportation has an important effect on the marketabiUty of chemicals. For that reason, transportation, along with numerous other factors, is often a significant consideration in determining the location of chemical production faciUties. In addition, convenient and economical access to water and rail transportation and the interstate highway system, as well as proximity to raw materials and markets, may influence the choice of warehouse and terminal sites for storage and redistribution of chemical products (see Plant location). 

This is primarily engaged in analysis of boiler water treatment matters and involves on-site studies of various problems and the chemical examination of corrosion products, boiler scales, etc. It can also carry out certain types of metallurgical, fuel and inorganic analysis. Normal wet methods of analysis coupled with a visible ultraviolet and atomic absorption spectrophotometer are used for a wide range of analytical applications. Equipment in use by the engineering insurers providing these services can include an ion chromatograph, spectrometer equipment, atomic... 

Finally, the topic of standardization ( plug-and-play ) has gained interest. WiU there be modular flexible plants in the future, for multi-purpose and on-site production Concerning the latter, the chemical manufacture of hazardous and explosive substances has attracted readership over many years. 

Depending on the diffusion of chemical danger the production sites have been graded as follows ... 

There is one element within the proficiency test process that causes difficulties for many of the participants. The proficiency-testing scheme trains participants to not report chemicals that are considered irrelevant within the scenario of the test and which, in real off-site analysis, could reveal confidential information that is considered not relevant in the context of the CWC. A review on how the test scenarios were applied revealed that participants are not really in a position to judge the relevancy of chemicals. It rather should be the Technical Secretariat making a final decision on the relevancy of chemicals instead, and, for that reason, accept the reporting of any chemical given that it is a degradation product of a Scheduled chemical or directly related to a Scheduled chemical.
