Industrial hydrogen production relies primarily on natural gas and hydrocarbon feedstocks to drive the various reaction chemistries that lead to hydrogen generation. Carbon dioxide, the ultimate co-product when such feedstocks and processes are employed, necessarily becomes a major contaminant of the generated hydrogen. Thus, carbon dioxide isolation and removal is an important process step in th ...

Ethylene and propylene are major chemical industry raw materials and consume a great deal of energy related to their production. It is estimated that 230 trillion BTU/yr are consumed in olefin/paraffin separations. Significant energy consumption is employed when cryogenically separating ethane from ethylene and propane from propylene. These cryogenic separations are difficult and are both capital ...

Coal gasification plants have exhibited sub-par performance and plant economics due to poor reliability and availability. A major contributor to the poor performance has been fouling of the syngas cooler located downstream of the gasifier. The fouling is due to vaporized ash from the coal gasification process depositing on the fireside surface of the tubes in the fire tube heat exchanger used for ...

THE RECENTLY COMPLETED TEST PROGRAM BY PENELEC AT THE EPRI/CQDC TEST FACILITY, HOMER CITY, PA, UNDER DOE CONTRACT DE-AC22-88PC88853 HAS AGAIN DEMONSTRATED THE EFFECTIVENESS AND THE POTENTIAL OF ASH FLOTATION TECHNOLOGY FOR FINE COAL CLEANING. THIS TEST PROGRAM CONFIRMED THE ASH EFFECTIVENESS WITH THE SEPARATION EFFICIENCIES EQUIVALENT TOTHOSE ACHIEVED BY ADVANCED CONVENTIONAL FLOTATION, BUT AT A S ...

60311 There are economic and environmental justifications for replacing conventional distillation processes with simpler membrane separations in certain applications. However, at present, there are no commercial membranes able to withstand the aggressive conditions associated with important industrial chemicals, including hydrogen fluoride, hydrogen chloride, and ozone. Prototype, chemic ...

60395 Emissions of volatile organic compounds (VOC) from gasoline refueling facilities continue to be an energy, safety, and environmental issue. In such applications, it is desired to vent the air in the system and keep the VOC behind. This project will develop a reverse separation membrane (RSM) system that allows for rapid venting of air while retaining the gasoline in underground storag ...

Many refinery product streams, particularly those from Ultra Low Hydrodesulfurisation units, are prone to haze due to water emulsions. Haze is also problematic for biodiesel production, as hazy fuel cannot be used until the haze settles or is removed, which creates costly scheduling and shipping delays. This project will develop a novel membrane process for the removal of dissolved and dispersed ...

ALTHOUGH ENERGY DISPERSIVE SPECTROMETERS ARE STANDARD ON MANY ANALYTICAL ELECTRON MICROSCOPES, WAVELENGTH DISPERSIVE (WDS) X-RAY SPECTROMETRY HAS THE ADVANTAGES OF HIGH RESOLUTION AND SENSITIVITY TO A WIDE RANGE OF X-RAY ENERGIES, INCLUDING THOSE DUE TO LOW Z ATOMS. THE STANDARD WORKHORSE OF WAVELENGTH DISPERSIVE X-RAY SPECTROMETRY IS THEJOHANN BENT CRYSTAL SPECTROMETER. VERY FEW ANALYTICAL TRANSM ...

The recovery of heat currently wasted in exhaust gases can reduce fuel consumption in almost every commercial and industrial sector. In the electricity generation sector alone, even modest improvements in energy recovery effectiveness would result in billions of dollars in savings annually. New materials made from conductive graphite have created a significant opportunity to produce heat exchang ...
