  • Freeze Drying

    Lyophilization, commonly referred to as freeze drying, is the process of removing water from a product by sublimation and desorption. The freeze drying process is optimised by the introduction of solvents and gas species to improve product quality and to enhance the drying process. Hiden's gas analysers provide detailed information about the gas/vapour composition during both the primary and secondary drying phases. Detection of the on-set of the secondary drying phase is readily detected. Analysis during the secondary drying phase enables a reduction in process cycle time and provides end point detection. Accurate determination of a user defined process 'end point' enables high consistency in product yield from batch to batch.

  • Gas detection analyzers for coil coating industry

    Coil Coating is a high-temperature solvent vapor monitoring application in which rolls of aluminum or steel are coated with a color finish, oven cured to desired specs and sold to makers of cans, rain gutters, home appliances, building & automotive products and other fabrications. Coil coating requires the use of our PrevEx Flammability Analyzers to monitor the flammability of the solvent vapor driven off during the drying process. PrevEx analyzers accurately measure solvent mixtures and can withstand the temperatures required to prevent sample clogging in coil coating plants.

    Gas Detection Solutions for GHG Monitoring

    Most sources of fugitive emissions are from multiple points rather than single point sources. So, open path area or perimeter monitoring provides more meaningful fugitive emissions data than an array of point sensors or a program of grab sampling. Point measurements may underestimate emissions because of missing locations with high gas concentrations, or conversely overestimate because they are located in areas of high concentrations. Grab sampling programs typically check only a small percentage of potential leak locations and extrapolate results to an entire facility. Wide margins of uncertainty are associated with such extrapolations. Open path monitoring provides continuously updated, real-time, integrated emissions across a facility boundary.This provides a complete picture of the fugitive emissions across that boundary,enabling identification of specific operations and times that give rise to higher emissions, and so enabling these emissions to be properly managed and controlled.

    Carbon capture and storage (CCS) applications

    Carbon Capture and Storage (CCS) is an emerging method of reducing greenhouse gas (GHG) emissions of power plants. In a process called ‘scrubbing’, the carbon dioxide emissions can be absorbed into chemical solvents consisting of amines or carbonates. Scrubbing is a well-established method of carbon capture, with virtually every commercial CO2 capture plant in operation using this process. In the process, the first step is the removal of impurities from the flue gas, such as hydrocarbons and oxides of both nitrogen and sulfur (NOx and SOx). Next the purified gas is passed through an absorption column filled with the chemical scrubbing solvent. The solvent reacts with the carbon dioxide and selectively absorbs it from the gas stream. When CO2-rich solvent is heated, the carbon dioxide is released as a nearly pure gas.

    VOCs Fugitive emissions detection

    An oil refinery or petroleum refinery is an industrial process plant where crude oil is processed and refined into more useful petroleum products, such as naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, etc,. Oil refineries are typically large, sprawling industrial complexes with extensive piping running throughout, carrying streams of fluids between large chemical processing units. The refining process releases a number of different chemicals into the atmosphere mostly Hydrocarbons which cause severe health and safety hazards.

    Title : Preliminary Sampling Methodology and Analytical Procedures for Ambient Sulfur Hexafluoride, Corporate Author : ARMY MEDICAL ENVIRONMENTAL ENGINEERING RESEARCH UNIT EDGEWOOD ARSENAL MD Personal Author(s) : Luckan,Susan K. ; Cooper,William J. Report Date : JAN 1973 Pagination or Media Count : 23 Abstract : A preliminary evaluation of techniques of sampling and gas chromatographic analysis for low levels of sulfur hexafluoride was conducted to determine the most feasible method for available equipment. Using a Tracor MT-150 gas chromatograph equipped with Nickel 63 electron capture detector and polarized dc voltable, it was possible to detect sulfur hexafluoride at a concentration of 0.06 ppb with a 5A molecular sieve column and nitrogen carrier gas, without preconcentration of the sample. Also, a comparison of glass and Saran sampling materials proved that no detectable loss of the tracer gas resulted with the Saran bags (between 6 ppm and 0.06 ppb SF6
