Small-scale integrated productions

It is possible to increase the efficiency to over 85% with an economic profit at higher thermal integration. There are two types of steam reformers for small-scale hydrogen production conventional reduced-scale reformers and specially designed reformers for fuel cells.

At this time, the petroleum industry was still a small scale affair and largely decentralized production, transportation, refining, and distribution of refined products were undertaken by separate companies. Periods of overcapacity caused price declines that cut deep into the profits of producers. In the last two decades of the nineteenth century, John D. Rockefeller imposed order on the industry by building a fully integrated corporation The Standard Oil T rust. 

Production Test. In a small-scale production test, tinplate containers with two commercially available enamels and two end-sealing compounds, which were selected from the results of this study, performed satisfactorily when packed with beef and ham. Beef was irradiated with 4.5-5.6 Mrad at 5, —30, and —90°C ham was irradiated with 3-4 Mrad and 6-7.5 Mrad at —30°C. For this production test, beef and ham were packaged in round tinplate containers and ham in Pullman tinplate containers, frozen and refrigerated products were shipped 1,200 miles by truck, and were gamma irradiated at various doses and temperatures. Irradiated products were shipped 1,200 miles in a non-refrigerated truck and stored at selected temperatures and humidities. The integrity of the cans was evaluated after storage for 10 days, 3 months, and 6 months. 

SSP of recycled PET (RPET) can be performed as either a continuous or a batch process. A continuous SSP offers a constant and overall higher productivity, as well as a more consistent product treatment, lower operating costs [117] and better process integration with a downstream manufacturing process. A batch SSP offers a larger degree of flexibility for small-scale operations with a large variation of raw material and final product specifications. 

Small-scale container-size production units can easily be fitted to an existing oil processing business or operate as stand-alone units. These are ideal for producing biodiesel in remote areas with limited demands. Such units can also be combined and even integrated with oil refining to create flexible production units. 

The question of suitability for decentrahsation becomes more critical in the case of vehicle-integrated hydrogen production systems, which must be economic at small scale. 

Heat flow data are not very sensitive to small-scale horizontal variations of heat production and integrate the heat production in the entire crustal column, and hence alleviate many of the sampling problems encountered when using only geochemical data. They are sensitive to heat production in the whole crustal column, including surficial rocks, which may have been affected by late-stage leaching and alteration processes, as well as deeper material which has remained untouched. Eurther, they are sensitive to the deepest crustal levels, which can seldom be sampled. 

When pure hydrogen is to be used as fuel, the gas must first be recovered from the process stream where it is produced. Membranes may be used for this purpose, and several of the new materials under development may be suitable depending on gas volume to be handled and process conditions like temperature and pressure. Along with the introduction of fuel cells, development of small-scale gas-processing units will follow. Several small, integrated production units with direct conversion of fuel to hydrogen gas combined with a membrane unit for hydrogen recovery are patented [125,126].
