Gas injection technology

In combination with CARBOJET high-speed gas injection technology, the CARBOFLEX technique can deliver higher levels of atmosphere homogeneity and product quality as well as cut costs even further.

This paper discusses the latest advances in manufacturing Community Antenna Television (CATV) cables via the gas injection process. Developments in polymer technology are discussed which have led to the production, by gas injection, of highly expanded, ultra low dielectric loss PE cable insulation for CATV and data transmission 3 refs. 

BioSparge is a closed-loop, in situ and ex situ bioremediation technology that uses vapor extraction, gas injection and biodegradation to remediate contaminant plumes below the ground-water level. This process works by extracting soil vapor from wells placed at the perimeter of... 

The first in situ industrial test was carried out at BP s Hull Research and Technology Centre in spring/summer of 2006 (Ingram et al., 2007) on a 750 mm diameter pilot scale fluidised bed with a central baffle plate and asymmetric gas injection to promote particle circulation, as shown in Figure 19. The fluid bed was operated under industrially relevant conditions of elevated temperature and pressure. Owing to the thickness of the lagging, the minimum detector separation was 1150 mm. 

Some of the technologies for dealing with this C02 are the same as acid gas injection, and thus they will be discussed here as well. 

Acid gas injection (AGI) has become a mature technology for disposing of acid gas, a mixture of C02 and H2S. AGI is particularly useful for small producers who have few options for dealing with the H2S. Larger producers, however, have seen the value in AGI as well and the industry has discovered that AGI is an environmentally friendly solution to a difficult problem. 

The sin >lcst flue gas desulfurisation technology is furnace injection, where a dry sorbent is injected into the upper part of the furnace to react with the SO2 in the flue gas. The finely grained sorbent is distributed quickly and evenly over the entire cross section in the upper part of the furnace in a location where the teiiq>erature is in the range of 750-12 50 C. Commercially available and cheap limestone (CaC03) or hydrated lime (Ca(OH)j) is used as sorbent. The sorbent reacts with SO2 and O2 to form CaS04. Below 750 C the reaction rate is too low. At temperatures over 1250 C the surface of the sorbent will be sintered, and the structure of the pores will be destructed, reducing the active surface area, The major part of S02-rcmoval takes place within 1 to 2 seconds. 

Nevertheless, there are limitations of even the most advanced amines-only based gas treatment technologies in handling very highly add gas loaded natural or associated oil field gases - especially for bulk acid gas removal when the acid gases are destined for cycling and/or disposal by re-injection. 

Finally, Total in collaboration with IFF has embarked upon a comprehensive program with a pooling of resources to develop new gas treatment technologies to better suit the bulk acid gas removal destined for re-injection applications. To this end, pre-treatment techniques and hybrid solvent processes are envisioned as the most cost-effective overall solutions. 

Technologies featured in Otis book indude steam Injection, radio frequency, Joule resistance, passive and active solar heating, and hot gas injection. Each technology is presented with actual applications, costs, advantages and disadvantages, and literature review. 

Process Description. The IFP-1500 process is best used to clean up Claus unit tail gas. The technology involved is essentially an extension of the Claus reaction itself but carried out in the liquid phase as shown in Figure 1. The tail gas at Claus unit exit pressure is injected into...
