Mobile plants

One of the most widely used chemical plants is certainly the exhaust pipe section of an automobile. The exhaust pipe system of automobiles shows all features of a chemical plant, as it consists of a catalytic reactor, supply pipes for the gases, heaters and control equipment such as the lambda sensor. The catalyst carriers of an exhaust pipe are not called micro structured reactors but, considering their micro dimensions, they actually belong to this group of reactors.

Most usually the pretreatment plant is a capital item fixed asset facility, but the trend is increasingly noticeable around the world today for the supply of properly conditioned MU water to be outsourced from a contractor, who either leases a mobile plant to the facility or generates a profit from the direct sale of water to the boiler plant.

According to the developer, a 5 ton per hour mobile plant could be designed and built for about 2.35 million (Canadian), plus or minus 25% (D17555X, p. 1 D17557Z, p. 1). In 1998, the vendor stated that operating costs for a 5 ton-per-hour plant would be from 30 to 35 (Canadian) per metric ton, excluding excavation and secondary stream costs. Total costs were estimated to be 140 (Canadian) per metric ton (personal communication, Abdul Majid, National Research Council of Canada, 1998). 

R.L Langerhans was my assistant during the initial discovery period (1948-1950), the first person to work with the clay bonding of zeolite powders, and assisted in siting and design of the Mobile plant and was its first plant manager. 

R. E. Cuddeback led the design team for the Union Carbide Mobile Plant for manufacture of molecular sieve products.

Some methods are already or are becoming established Potential to reduce volume of material requiring disposal or expensive treatment Wide range of contaminants treatable Wide range of materials treatable Some in situ methods require only little site disruption Mobile plant available for some methods Secondary waste streams may require treatment or disposal Soils with high clay or peat content may be difficult to treat Use of some solvents will have health and safety implications Quality assurance measures needed, especially for in situ methods Approval by regulatory authority may be needed...

To assess the relative extent of - Tc sorption and its mobility, plants were grown for 40 days in hydroponics amended with 10 M Tc04. Uptake rates in roots and leaf concentrations after 48 h were determined (Tabic 4.3. A).

Mobile plant installed on the trailer chassis. Collapsible solar array. Electrolyzer with a solid polymer electrolyte. There are water storage tanks and a water purification (deionization) unit. 

For stationary fuel-cell-based power plants, the most important parameter is the energy conversion efficiency, inasmuch as this will define the fuel consumption per unit of electric power generated. For portable and other mobile power plants, the most important parameters are the power density and the energy density, inasmuch as they reflect the mass and volume of the mobile plant. 

Hot mix asphalt plants are installed close to the aggregate production source (quarries), in suitable rural locations nearby expected projects or at the project site. The mixing plants can be stationary or mobile. The mobile plants provide flexibility and are less costly, but daily production outputs as high as those of stationary plants cannot be achieved. 

Entry into fixed or mobile plant and vessels, e.g. road tankers, rail tankers or sea tankers carrying leaded gasoline, e.g. for inspection, cleaning and maintenance purposes. 

Stationary crushing plants, i.e., installed in a fixed location, are predominant in the cement industry, but for new installations, especially when large throughputs are required, mobile plants — self-propelled or easily relocatable — have become much more numerous since the early 1960s, now that the various systems for moving them from one working position to the next have proved reliable. 

Mobile plants in the more specific sense of the term have their own integral travelling machinery, enabling them to proceed from one location to the next unaided.
