Naftogaz wants to buy Russian gas from Germans - Azarov
National joint stock company Naftogaz of Ukraine is in talks with the German energy concern RWE on Russian gas imports from Europe to Ukraine in a reverse order, which would be cheaper than buying gas directly from Russia.
Ukrainian Prime Minister Mykola Azarov said this in an interview with the German newspaper Die Welt, the online version of which was published on Tuesday.
"Naftogaz wants to buy Russian gas from the German RWE in the so-called reverse order," he said.
At the same time, the head of the Ukrainian government noted that Kyiv still hopes to sign a new gas deal with Russia. "Otherwise we will really buy Russian gas from a German company, which would be cheaper than directly from Russia. And it would be a paradox," he said. In this context, the Prime Minister reminded that Ukraine paid $1.2 billion for the Russian gas delivered in February.
According to Azarov, because of "unfair" high prices for Russian gas, Ukraine is forced to seek alternative sources. In particular, it is planned to build a terminal for liquefied natural gas in the Black Sea. "We have already reached agreement with the Spanish firm Socoin on preparing a relevant study," he said. However, the Prime Minister added, this takes getting Turkey's permission for the passage of tankers with liquefied gas through Bosporus Strait. The transportation of gas from Azerbaijan via the Black Sea is also considered as an alternative, but for this, he noted, Azerbaijan should build a plant for liquefying natural gas.

Boiko: Ukraine ready to accept any option to reduce gas price
Ukraine is considering options to reduce the price of gas and is ready to accept any cost-effective option, Ukrainian Energy and Coal Industry Minister Yuriy Boiko said at a Cabinet of Ministers meeting on Wednesday.
"We are considering various options to reduce the price of gas, whose ultimate goal is to improve the performance of our economy. And as part of this consideration, any option that is economically justified will be accepted," he said.
Boiko also noted that Ukraine planned to continue to provide gas supplies in various routes, but domestic gas production remains a priority.
"Given the trend that we saw in two months, we will meet our commitments to increase our own production of natural gas by a billion cubic meters this year," the minister said.

2. Coal to SNG Technology
2.1. Brief Description
Steam‐oxygen gasification, hydrogasification, and catalytic steam gasification are the three gasification
processes used in coal‐to‐SNG. The proven and commercialized method of gasification for the coal‐to‐
SNG process, however, is the steam‐oxygen gasification process.
2.1.1. Steam‐oxygen gasification
In the steam‐oxygen process of converting coal to SNG, coal is gasified with steam and oxygen. The
gasification process produces carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2), methane
(CH4), and higher hydrocarbons such as ethane and propane. The gas composition depends upon the
gasifier conditions, i.e., temperature and pressure. At higher temperatures and pressures, the major
products are CO and H2. Three moles of H2 are required to react with each mole of CO to produce one
mole of CH4. The concentration of H2 in syngas is increased by a step called the water‐gas shift reaction,
which is followed by a gas cleaning. The cleaned gas, consisting primarily of CO and H2, reacts in the
methanation reactor in the presence of a catalyst to produce CH4 and H2O. The resulting gas, after H2O
condensation and polishing, if required, is synthetic natural gas (SNG). Figure 1 shows the flow diagram
of steam‐oxygen gasification. The essential components of the process are the air separation unit, the
gasifier, the water‐gas shift reactor, syngas cleanup, and the methanation reactor. Each component is
described below.
Air Separation Unit
Oxygen required in the gasifier is either supplied by vendors or generated on‐site using an air separation
unit (ASU). Cryogenic air separation is the technology generally used in the ASU.
Gasifier
The most important and basic component of the coal‐to‐SNG process is the gasifier. The gasifier
converts coal into syngas (primarily CO and H2) using steam and oxygen (O2), generally at a high
temperature and under high pressure.
