By cooling the gas is condensed and then available as hydrocarbon feedstock for other processes (some 85% of the MPW input). The light hydrocarbon gas (15% of the MPW input) that remains after cooling is compressed, reheated and returned to the reactor as fluidising gas. It can also be used as a fuel for the cracking process, though other recovery options are being studied as well.

Due to the nature of the particular type of cycle gas compression at the facility, a significant release of hydrocarbon, though highly unlikely, could not be placed in a frequency category of 1 "not realistically expected to occur." For these reasons, the qualitative assessment team ranked the scenario as a "2" frequency. It was felt that a QRA would only confirm this evaluation. 

Steam jets are also employed to recompress low-pressure steam to a higher-pressure steam. Jets are sometimes used to compress low-pressure hydrocarbon vapors with higher-pressure hydrocarbon gas (instead of steam). They are really wonderful and versatile machines. 

The decomposition of PVC leads to the formation of HCl, which is neutralized by bringing the hot gases into contact with a solid absorbent. This results in a CaCl2-fraction that has to be landfilled. The purified gas is cooled, most of the hydrocarbon condensed as distillate feedstock. The remaining light hydrocarbon gas is compressed, reheated and returned to the reactor as fluidizing gas. Part of the stream could be used as fuel gas for heating the reactor, but as it is olefin-rich, recovery options are underway. 

Here, the energy carries are categorised into three as shown in Figure 2, namely hydrocarbons, electricity and hydrogen. As for the hydrocarbon energy carriers, gasoline, kerosene, liquefied petroleum gas, compressed natural gas and so on are used at present, while dimethyl ether, ethanol, synthetic fuels and so on will be used in the future. 

Gas turbines will pass a mixture of gases normally dominated by air but also containing the products of hydrocarbon combustion. It is found that the specific heat is a function of temperature only, and the gas compressibility factor stays very close to unity, Z % 1, for sdl industrial applications. This latter fact idlows the second term on the right-hand side of equation (16.40) to be integrated analytically ...

The PEM fuel cells utilize environmentally friendly fuel—oxygen and hydrogen that can be produced via electrolysis of water. Electrolysis of water when using renewable resources (i.e., solar or wind) provides a clean source of fuel that is then reverted to the water by the fuel cell. Currently however, the majority of the world s hydrogen is generated from hydrocarbon fuels since the economics are more favorable than electrolysis of water. The current high cost of electrolysis is related to the raw material cost of cell hardware and the limited volume of cell hardware within the market. If widely adopted, low pressure electrolysis can be reasonably cheap, if auxiliary systems are utilized for gas cleanup (humidity removal) and gas compression. 

Sharing of past major incidents with other oil and gas industries provides useful input data for similar process industries in order to identify the most critical barriers and improve their safety processes. One poignant example highlights this matter. In 1998 there was an accident in the gas compression stage of a Middle East oil and gas plant which caused 7 dead as a result of fuel accumulation and vapor cloud explosion which was very similar to the Texas City Refinery disaster on March 23, 2005 in which a distillation tower was overfilled and an uncontrolled release of hydrocarbons led to a major explosion and fires. Fifteen people were killed and 180 were injured in the worst disaster in the United States in a decade. In both incidents, excess hydrocarbons were diverted into a pressure relief system that included a blowdown stack. In the Iranian case, it was equipped with a flare, but one which the operator didn t ignite in Texas City the blowdown stack was not equipped with a flare to burn off hydrocarbons as they were released. As a result, the flammable overflow from the tower entered the atmosphere. Ignition of the escaped hydrocarbons was enabled by startup of a nearby vehicle resulted in the explosion and subsequent fires (Hopkins, 2008). This example shows the repetitive patterns of accidents, and root causes of events all over the world in this sector. The lesson of this paper is that accidents in one country, where the scenarios are very similar, can and should serve as lessons to prevent the same scenario being actualized in other countries. 

A simplified flow diagram of one version of the Ryan/Holmes technology is shown in Figure 16-19. In a typcal application of the process for carbon dioxide-rich EOR gases, the feed gas stream is first passed through a separator (I) to remove any liquid water or hydrocarbons, then compressed to 360 psig (2), and dehydrated in a conventional glycol or molecular sieve unit (3). 

Offshore production platforms and drilling rigs are generally arranged into Safe and Hazardous Areas. The two areas should be separated from one another and may have physical barriers between them. The Safe Area will include accommodations, the control room, UPS (uninterruptible power supply), emergency power generation equipment, and nonhazardous platform utilities such as water and compressed air. The Hazardous Area contains the flare, derricks, gas compression, hydrocarbon separation, the wellhead, and drilling facilities. 

Wang (2001) noted Because most gases are extremely compressible under reservoir conditions, in many cases the bulk modulus (incompressibility) of a hydrocarbon gas can be set as 0.01 to 0.2 GPa in seismic modeling. Errors in gas bulk modulus will yield little uncertainty in the calculated seismic properties in a fluid-saturated rock". 

Benzene was first isolated by Faraday in 1825 from the liquid condensed by compressing oil gas. It is the lightest fraction obtained from the distillation of the coal-tar hydrocarbons, but most benzene is now manufactured from suitable petroleum fractions by dehydrogenation (54%) and dealkylation processes. Its principal industrial use is as a starting point for other chemicals, particularly ethylbenzene, cumene, cyclohexane, styrene (45%), phenol (20%), and Nylon (17%) precursors.
