New way to turn sewage into biofuel within minutes!

November 3, 2016

Washington, Nov 3: Sewage treatment plants may soon turn human waste into fuel, thanks to a new technology that mimics the conditions the Earth uses to create crude oil - achieving in minutes something that takes Mother Nature millions of years.fuelfromsewa

The technology, hydrothermal liquefaction (HTL), creates a material similar to petroleum pumped out of the ground, with a small amount of water and oxygen mixed in.

This biocrude can then be refined using conventional petroleum refining operations, researchers said.

According to researchers from the US Department of Energy's Pacific Northwest National Laboratory (PNNL), wastewater treatment plants treat about 34 billion gallons of sewage every day.

That amount could produce the equivalent of up to about 30 million barrels of oil per year in the US.

PNNL estimates that a single person could generate two to three gallons of biocrude per year.

Sewage, or more specifically sewage sludge, has long been viewed as a poor ingredient for producing biofuel because it is too wet.

The approach being studied by PNNL eliminates the need for drying required in a majority of current thermal technologies which historically has made wastewater to fuel conversion too energy intensive and expensive.

HTL may also be used to make fuel from other types of wet organic feedstock, such as agricultural waste.

Using HTL, organic matter such as human waste can be broken down to simpler chemical compounds.

The material is pressurised to 3,000 pounds per square inch - nearly one hundred times that of a car tire.

Pressurised sludge then goes into a reactor system operating at about 350 degrees Celsius.

The heat and pressure cause the cells of the waste material to break down into different fractions - biocrude and an aqueous liquid phase.

Sheikhupura, May 26: Younus, the brother-in-law of Asia Bibi, a Christian woman convicted of blasphemy by a Pakistani court, was killed in Sheikhupura city of Punjab province in Pakistan on Monday.

According to the FIR, Younus had gone to his farms on May 24 and did not return home at night. His body with throat slit was traced in the farm the following morning.

It is believed that, hailing from minority Christian community, Younus was killed in a rivalry.

This is not the first time that somebody associated with Asia Bibi has been murdered in cold blood.

In 2011, Salman Taseer, the influential governor of Punjab was assassinated after he made headlines by appealing for the pardon of Asia Bibi, who had been sentenced to death for allegedly insulting Prophet Muhammad.

A month after Taseer was killed, Religious Minorities Minister Shahbaz Bhatti, a Christian who spoke out against the laws, was shot dead in Islamabad, underlining the threat faced by critics of the law.

Asia Bibi is now living in exile after the Supreme Court of Pakistan acquitted her based on insufficient evidence in October 2018.

Recounting the hellish conditions of eight years spent on death row on blasphemy charges but also the pain of exile, Asia Bibi recently broke her silence to give her first personal insight into an ordeal that caused international outrage.

French journalist Anne-Isabelle Tollet, who has co-written a book about her, was once based in the country where she led a support campaign for her."You already know my story through the media," she said in the book.

"But you are far from understanding my daily life in prison or my new life," she said. "I became a prisoner of fanaticism," she said. In prison, "tears were the only companions in the cell".

She described the horrendous conditions in squalid jails in Pakistan where she was kept chained and jeered at by other detainees.

Pakistan's blasphemy laws carry a potential death sentence for anyone who insults Islam. Critics say they have been used to persecute minority faiths and unfairly target minorities.

Pakistan's Prime Minister Imran Khan defended the country's strict blasphemy laws during his election campaigns. The status quo is still in place.

No government in Pakistan was ready to make changed to the blasphemy law due to fears of a backlash.

Chengdu, China, Jul 27: The American flag was lowered at the United States consulate in Chengdu on Monday, days after Beijing ordered it to close in retaliation for the shuttering of the Chinese consulate in Houston.

Footage on state broadcaster CCTV from outside the consulate showed the flag being slowly lowered early Monday morning, after diplomatic tensions soared between the two powers with both alleging the other had endangered national security.

Relations deteriorated in recent weeks in a Cold War-style standoff, with the Chengdu mission Friday ordered to shut in retaliation for the forced closure of Beijing's consulate in Houston, Texas.

The deadline for the Americans to exit Chengdu has been unclear, but the Chinese consulate in Houston was given 72 hours to close after the original order was made.

On Saturday news agency reporters saw workers removing the US insignia from the front of the consulate.

Over the weekend, removals trucks entered the US consulate and cleaners were seen carting large black rubbish bags from the building.

Beijing says closing the Chengdu consulate was a "legitimate and necessary response to the unreasonable measures by the United States", and has alleged that staff at the diplomatic mission endangered China's security and interests.

Washington officials, meanwhile, said there had been unacceptable efforts by the Chinese consulate in Houston to steal US corporate secrets.

Jun 15: Oil prices fell on Monday, with U.S. oil dropping more than 2%, as a spike in new coronavirus cases in the United States raised concerns over a second wave of the virus which would weigh on the pace of fuel demand recovery.

Brent crude futures fell 66 cents, or 1.7%, at $38.07 a barrel as of 0016 GMT, while U.S. West Texas Intermediate (WTI) crude futures fell 81 cents, or 2.2%, to $35.45 a barrel.

Both benchmarks ended down about 8% last week, their first weekly declines since April, hit by the U.S. coronavirus concerns: More than 25,000 new cases were reported on Saturday alone as more states, including Florida and Texas, reported record new infection highs.

"Concerns about the recent uptick in COVID-19 infections in the U.S. and a potential 'second wave' are weighing on oil at the moment," said Stephen Innes, chief global market strategist at AxiCorp.

Meanwhile, an OPEC-led monitoring panel will meet on Thursday to discuss ongoing record production cuts to see whether countries have delivered their share of the reductions, but will not make any decision, according to five OPEC+ sources.

The Organization of the Petroleum Exporting Countries (OPEC) and its allies, collectively known as OPEC+, have been reducing supplies by 9.7 million barrels per day (bpd), about 10% of pre-pandemic demand, and agreed in early June to extend the cuts for a month until end-July.

Iraq, one of the laggards in complying with the curbs, agreed with its major oil companies to cut crude production further in June, Iraqi officials working at the fields told Reuters on Sunday.
