Steam gasification experiments were carried out in a kW dual fluidized bed steam gasifier at a temperature range of to °C with straw and by:

It emphasizes the reservoir aspects of conventional thermal recovery processes - combustion, steam, hot water, and hot gases - and considers in detail and at length the application of these processes to oil reservoirs.

This paper proposes an overview of waste-to-energy conversion by gasification processes based on thermal plasma. In the first part, basic aspects of the gasification process have been discussed. Thermal desorption works well at separating organics from refining wastes, coal tar wastes, waste from wood treatment, and paint wastes. It can separate solvents, pesticides, PCBs, dioxins, and fuel oils from contami-nated soil. The equipment needed to do this can treat up to 10 tons of contami-nated soil per hour.

This book covers current refinery processes and process-types that are likely to come on-stream during the next three to five by: He is recognized internationally as an expert in the characterization, properties, and processing of conventional and synthetic fuels and as a chemist with more than 35 years of experience in thermal/process chemistry, thermodynamics, refining of petroleum, heavy oil, and tar sand bitumen, and physics of crude with emphasis on distillation Cited by: This chapter explores thermal cracking and coking in the process of petroleum refining.

Thermal cracking is the cracking of heavy residues under severe thermal conditions. The liquid products of this process are highly olefinic, aromatic, and have high sulfur content. They require hydrogen treatment to improve their properties.

This chapter presents viable options to the antiquated definitions of the heavy feedstocks (heavy oil, extra-heavy oil, and tar sand bitumen) as well as an introduction to the various aspects of heavy feedstock refining in order for the reader to place each feedstock in the correct context of properties, behavior, and refining needs.

He is recognized internationally as an expert in the characterization, properties, and processing of conventional and synthetic fuels and as a chemist with more than 35 years of experience in thermal/process chemistry, thermodynamics, refining of petroleum, heavy oil, and tar sand bitumen, and physics of crude with emphasis on distillation.

Introduction to Enhanced Recovery Methods for Heavy Oil and Tar Sands, Second Edition, explores the importance of enhanced oil recovery (EOR) and how it has grown in recent years thanks to the increased need to locate unconventional resources such as heavy oil and shale.

Unfortunately, petroleum engineers and managers aren't always well-versed. Thermal decomposition or cracking of the constituents begins around °C ( °F) and the rate increases markedly above this temperature.

High temperatures may also have a deleterious effect on the lubricating properties of the product. Refining operations Petroleum refining processes and operations can be separated into five basic areas: • Fractionation (distillation) is the separation of crude oil in atmospheric and vacuum distillation towers into groups of hydrocarbon compounds of differing boiling-point ranges called "fractions" or "cuts.".

The book includes (1) comparisons of conventional feedstocks with heavy oil, tar sand bitumen, and bio-feedstocks; (2) properties and refinability of the various feedstocks; (3) thermal processes versus hydroprocesses; and (4) the influence of refining on the by: Constructing good low temperature instruments requires information on the properties of materials used in their construction, in particular the thermal conduc-tivity.

Unfortunately, this is poorly known for many materials. Collections of data in text books tend to be incomplete and in the worst cases are misleading. In order to get highly efficient tar decomposition, the temperature of thermal cracking needs to be very high, which results in operating cost increase.

Catalyst cracking can modify the composition of product gases at low temperature with high carbon conversion by: 4. Characterization of Toluene Insolubles from Low-Temperature Coal Tar Article in Energy Technology 2(6) June with 36 Reads How we measure 'reads'.

Highlights Low temperature catalytic gasification technology used to produce H 2 from fowl manure. High H 2, CO and total gas yields obtained during the manure gasification.

Manure pyrolysis can be promoted due to the catalytic effect of minerals. Manure volatiles can be completely cracked into little molecules under Ni/Al 2 O 3 catalyst.

Catalytic role of HC char and HC ash can be attributed Cited by: Only 2 participants give lumped calorific values for tar. One organisation uses 30 MJ/kg for all tar. This is a low value and can only valid for tar with a high moisture or oxygen content, i.e.

typical for low temperature formation. Molar weight for tar is used when estimating the density and the calorific value per mole or m³ for a tarry Size: KB. In general terms, the quality of tar sand bitumen is low compared to that of conventional crude oil and heavy oil.

The high carbon residue of heavy oil and bitumen dictate that considerable amounts of coke will be produced during thermal refining (see Table 1.) Upgrading and refining bitumen requires a different approach to that used for upgradingFile Size: KB.
