Abstract. Underground Coal Gasification (UCG) is a mininggasification process that produces synthesis gas from in situ coal by injecting air (or oxygen and steam) and extracting the produced gas via boreholes. The resulting synthesis gas ('syngas') produced by UCG can be used directly as a fuelgas or deepcleaned to produce many other products like chemicals, liquid fuels, hydrogen and ...

The coal gasification process is used in commercial production of synthetic gas as a means toward clean use of coal. The conversion of solid coal into a gaseous phase creates opportunities to produce more energy forms than electricity (which is the case in coal combustion systems) and to separate CO2 in an effective manner for sequestration.

There are several steps in coal gasification. Let's focus on step 1: conversion of the solid coal to a burnable gas. In the gasifier, crushed coal is combined with steam at high pressure and temperature. The quantity of oxygen is limited to prevent complete combustion of the coal. Instead, the carbon reacts with the steam to form a mixture of ...

What's The Difference Between Upstream and Downstream?

What's The Difference Between Upstream and Downstream?

In the same way that a raw material provider is "upstream" or "up river" from a factory, a raw data provider is "upstream" from the API that processes it. Similarly, the API which takes the output of another component's processing is considered "downstream" or "down river". Let's look at a practical example.

What Is "Upstream" and "Downstream" in Supply Chain Management? Thomasnet

Downstream supply chain can also be thought of as the "demand" while upstream supply chain is the "supply.". Supply chain managers seek to balance demand and supply to make sure that there are no lost sales, inventory shortages, or overordering. Supply chain inefficiencies can waste up to 25% of operating costs, so matching supply and ...
