Abstract Hydrogen is seen as a potential fuel for the future; its choice is driven by the increasing awareness of the necessity for clean fuel. Together with the simultaneous development of “green technologies” and sustainable development, a current goal is to convert waste to energy or to create energy from a renewable resource. Biological processing [of renewables] or bioremediation of waste to create hydrogen as a product fulfils this goal and, as such, is widely researched. In this work, an already established process, using a hydrogenase up‐regulated strain ‐ was characterised and the important process parameters were established. This bacterial strain has the potential for industrial‐scale hydrogen production from, for example, waste sugars. Previous work, repeated here, showed that hydrogen could be generated by E.

DEPARTMENT OF COMMERCE, Frederick B. Dent, Secretary NATIONAL BUREAU OF STANDARDS, Richard W. Roberts, Director A Gas Dilution System for Arsine-Air Mixtures ABSTRACT A gas -blending system originally designed for chlorine-air mixtures was modified for producing arsine-air mixtures in the concentration range from 0.02 to 0.25 ppm. This system has been tested in order to provide accurately known concentrations of arsine- in-air for calibration of analytical monitor- ing devices. An analytical method has been developed for checking the concentration of arsine in the work- ing standard and consists of the spectrophotometric measurement of an arsine-diethyldithiocarbamate complex in solution. 1. INTRODUCTION The system originally designed for preparing chlorine- air mixtures [1] has been adapted for producing arsine-air mixtures in the range from 0.02 to 0.25 ppm. The system combines a gas blending unit and an analytical unit. The gas blending unit produces concentrations of arsine by dilu- tion of a relatively high concentration of arsine in nitrogen (i.e.

Diving Air Compressor - Wikipedia, the Free Encyclopedia Diving Air Compressor from Wikipedia, the Free Encyclopedia
2/8/2014 Diving air compressor - Wikipedia, the free encyclopedia Diving air compressor From Wikipedia, the free encyclopedia A diving air compressor is a gas compressor that can provide breathing air directly to a surface-supplied diver, or fill diving cylinders with high-pressure air pure enough to be used as a breathing gas. A low pressure diving air compressor usually has a delivery pressure of up to 30 bar, which is regulated to suit the depth of the dive. A high pressure diving compressor has a delivery pressure which is usually over 150 bar, and is commonly between 200 and 300 bar. The pressure is limited by an overpressure valve which may be adjustable. A small stationary high pressure diving air compressor installation Contents 1 Machinery 2 Air purity 3 Pressure 4 Filling heat 5 The bank 6 Gas blending 7 References 8 External links A small scuba filling and blending station supplied by a compressor and Machinery storage bank Diving compressors are generally three- or four-stage-reciprocating air compressors that are lubricated with a high-grade mineral or synthetic compressor oil free of toxic additives (a few use ceramic-lined cylinders with O-rings, not piston rings, requiring no lubrication). Oil-lubricated compressors must only use lubricants specified by the compressor's manufacturer. Special filters are used to clean the air of any residual oil and water(see "Air purity"). Smaller compressors are often splash lubricated - the oil is splashed around in the crankcase by the impact of the crankshaft and connecting A low pressure breathing air rods - but larger compressors are likely to have a pressurized lubrication compressor used for surface supplied using an oil pump which supplies the oil to critical areas through pipes diving at the surface control point and passages in the castings.

Case Study: Membrane Co2 Removal from Natural Gas, Grissik Gas Plant, Sumatra, Indonesia
CASE STUDY: MEMBRANE CO2 REMOVAL FROM NATURAL GAS, GRISSIK GAS PLANT, SUMATRA, INDONESIA Charles L. Anderson Air Liquide – MEDAL, L.P. Newport, Delaware 19804 USA (1) 302 225-2102 [email protected] Anggiat Siahaan ConocoPhillips Jakarta, Indonesia (62) (21) 524-1987 [email protected] Abstract One of the world’s largest membrane systems is used for bulk removal of CO2 from natural gas at the Grissik gas processing plant in South Sumatra, Indonesia. The membrane system processes 310 MMSCFD of natural gas, reducing CO2 from 30% to 15%. The Grissik plant is termed a membrane plus amine hybrid which offers particularly attractive operational benefits. The membrane system has been operating for more than four years with no membrane replacement and offers the benefit of very long membrane life. CASE STUDY: MEMBRANE CO2 REMOVAL FROM NATURAL GAS, GRISSIK GAS PLANT, SUMATRA, INDONESIA Charles L. Anderson, Air Liquide – MEDAL, L.P., Newport, Delaware, USA Anggiat Siahaan, ConocoPhillips, Jakarta, Indonesia Introduction ConocoPhillips operates the Grissik gas processing plant on behalf of its partners, Talisman Energy Inc., Pertamina and BPMigas. The Grissik plant, located in South Sumatra, Indonesia, pictured in Figure 1, processes 310 MMSCFD of natural gas, primarily reducing CO2 concentration from 30% in the raw feed down to 3% in the sales gas. Figure 1. Grissik Gas Plant Process Overview The Grissik plant CO2 removal process utilizes both membrane separation and amine absorption technology, termed a membrane plus amine hybrid. A simplified process flow diagram is shown in Figure 2. The Thermal Swing Adsorption (TSA) removes heavy hydrocarbons, serving the triple function of membrane pre-treatment, feed gas dehydration and sales gas hydrocarbon dew pointing.

Producing Clean Fuel Gas On-Site
IMPROVE GAS TURBINE/ENGINE PERFORMANCE AND REDUCE MAINTENANCE USING MEMBRANES FOR FUEL GAS CONDITIONING Authors: Sachin Joshi, Hesham Hussain, Priyanka Tiwari, Daaniya Rahman, and Tim Aldajani Membrane Technology and Research, Inc. 39630 Eureka Drive, Newark, CA 94560, Tel: (650) 543-3357 [email protected] ABSTRACT Unprocessed raw natural gas is the major source of fuel for turbines/engines in power generation and compression applications in many condensates rich shale gas plays such as Marcellus, Utica, Bakken, Eagle Ford and Niobrara. When raw natural gas containing heavy and sour gas is used as fuel for powering turbines and engines, serious damage is caused to their components, thereby reducing efficiencies and in some cases complete equipment shutdown. This has an immediate impact on oil and gas production leading to substantial losses in revenues. This paper describes the use of unique heavy hydrocarbons and acid gas-permeable membranes to produce clean fuel gas from raw shale gas. Numerous fuel gas conditioning membrane units have been installed around the world by companies like Marathon Oil, Markwest Energy, Williams Energy, EQT Corp., Chevron for reducing the heavy & sour contents from raw gas. The key advantage of using membranes for clean fuel gas is its simplicity in operation. The membranes are passive units with no moving parts. No pre-treatment is required for their operation except for standard filtration. The units are designed for unattended operator attention and are virtually maintenance-free. The membranes work on the principle of passing heavy hydrocarbons, acid gases and water through the membranes, leaving a clean gas to be used as fuel.
