The West African coastal nation of Angola was the setting in 2014-15 of a landmark methane emissions discount undertaking that originated within the Permian Basin.
Permian Basin Worldwide Oil Present President Larry Richards was president-CEO of HY-BON Engineering when the Midland firm was awarded the Angola undertaking by the Chevron Corp. and Richards offered the outcomes with Chevron Undertaking Supervisor Frank Christiano on the International Fuel Flaring Discount Partnership and International Methane Initiative in Amsterdam.
“This gasoline had traditionally been flared at every offshore oil platform due to the dearth of a pure gasoline pipeline,” Richards stated Monday. “The technical challenges have been in compressing the related gasoline that included lots of heavier gases along with methane like propane and butane.
“Whenever you compress these heavier gases, they have a tendency to hit their dew level and alter again to a liquid. Compressors actually don’t like compressing liquids. It’s like pouring water into the consumption of your air compressor at dwelling. The offshore gasoline was very low strain and there was a excessive chance of liquids dropping out of it all through the method.”
HY-BON constructed all of the gear and shipped the items to Houston “the place groups from Angola loved our tradition and West Texas barbecue as they skilled on the gear previous to cargo,” Richards stated. “The undertaking was a powerful success, capturing over 25 million cubic ft of beforehand flared gasoline per day and paying for itself with simply the hydrocarbon liquids recovered within the course of. Most significantly, it confirmed all gamers concerned that it was potential and commercially viable to seize this difficult gasoline stream.
“On the time no Angolan liquefied pure gasoline plant existed, so the gasoline was compressed into a big underground pure storage cavern till it could possibly be utilized by the LNG facility on the drafting board.”
Richards stated the reductions in gasoline venting and flaring had the impact of eradicating 812,000 vehicles from the highway or planting 1.1 million acres of timber.
With 9 billion barrels of confirmed oil reserves and 11 trillion cubic ft of pure gasoline reserves, Angola is the second largest oil producer in Africa, trailing solely Nigeria, and its 1.2 million barrels per day of oil manufacturing making it one of many continent’s greatest producers.
With Luanda as its capital, Angola will use its functionality of processing 1.1 billion cubic ft of pure gasoline per day for LNG to assist heat Germany, France and the UK this winter. The nation’s inhabitants is 34 million.
The U.S. State Division says Angola is doing higher than most different West African nations, nevertheless it has not absolutely recovered from its years of warfare. “Though the nation is sub-Saharan Africa’s largest oil producer and has nice agricultural potential, two-thirds of the inhabitants lives in poverty,” a State Division spokesman stated in October.
“The US has labored with Angola to take away 1000’s of landmines, promote environmental conservation and assist warfare refugees and internally displaced individuals return to their houses. Angola is eligible for preferential commerce advantages below the African Development and Alternative Act and the usand Angola have signed a commerce and funding framework settlement that seeks to advertise larger commerce and funding between the 2 nations.”
Richards stated Angola’s LNG undertaking has grown to incorporate seven LNG supertankers and three loading jetties.
“This distinctive undertaking is an ideal instance of forefront know-how getting used to enhance the surroundings and provide clean-burning pure gasoline to markets that desperately want it,” he stated. “One of many causes we’re so excited concerning the 2023 PBIOS is that it’s going to show and spotlight applied sciences and improvements which can be driving the environmental stewardship and effectivity good points of the oil trade throughout the globe.
“It’s wonderful how lots of the high onshore improvements over the previous decade have been born on wellsites and in workplaces inside 100 miles of the Ector County Coliseum.”
