Enhanced Production As part of a complete sour gas purification and sulfur recovery scheme, Black & Veatch provided process design engineering, technology licensing and field support services. The Puguang Natural Gas Plant can process up to 36 million normal cubic meters of raw natural gas per day. It removes virtually all hydrogen sulfide, which makes up nearly 15 percent of the raw gas volume, and converts it to elemental sulfur. It also reduces carbon dioxide content from 10 percent to three percent of total volume to meet sales gas specifications. The processing plant also serves as one of the largest sulfur production facilities in the world, producing up to 8,400 metric tons per day and 3 million tons annually. China is currently the world’s largest consumer and importer of elemental sulfur, which is primarily used as feedstock to produce sulfuric acid and ultimately, phosphate fertilizers. In 2009, it consumed approximately 11 million tons, with approximately 80 percent coming from imports. The Puguang Field, with its 3 million tons of annual sulfur production capacity, is capable of meeting more than 25 percent of China’s elemental sulfur demand. Related Insights FLNG Solutions Prove To Be Much More Than Potential It was roughly a decade ago when the initial introduction of floating liquefied natural gas (FLNG) solutions sought to help bring uneconomic gas reserves offshore, such as those in remote locations, to the market. Over the past few years, however, we’ve watched as offshore FLNG capabilities have moved closer to the mainland, offering a very flexible and economical solution to operators looking to offload their supply around the world. Four Big Trends in Gas-to-Power Hold Promise for U.S. Market Major energy shifts are afoot, and the United States will play a critical role going forward. The EIA projects that by 2022, the U.S. will become a net energy exporter, according to its newly released Annual Energy Outlook 2018. For natural gas, this shift will happen even earlier, around 2020, the EIA says. Market Strives to Deliver Over Pipeline Challenges As if the persistent low-price environment wasn’t enough, rampant natural gas production in the Appalachian and Permian Basins is ramping up concern that pipeline take-away capacity can’t keep up. This comes as the United States natural gas industry prepares to enter one of its strongest growth periods to date, driven by increasing global demand for low cost natural gas supplies and growing domestic demand for cleaner energy sources. Southeast Asia’s Journey Toward a Cleaner Energy Future Strong economic growth, low gas prices and environmental goals are transforming natural gas demand in Southeast Asia. Liquefied Natural Gas Continues Growth Trajectory While Challenges Linger In the United States, it’s become somewhat of a modern gold rush: drillers racing to free deeply trapped natural gas to quench rising global demand, fueled by an accelerating migration away from coal and the desire for cleaner-burning, greener power options. Related Project Stories Industrial Wastewater Treatment Keeps Power Facilities Compliant A large utility located in the Midwest needed to build a low volume wastewater (LVW) treatment system to improve to two of its coal-burning plants necessitated by the Coal Combustion Residuals (CCR) rule. Pilot Plant Cleans, Repurposes Water from Oil Recovery Operations With water already at a premium in a stubbornly parched region of the United States, a global oil giant had sustainability in mind when it searched for ways to clean and repurpose water produced as a byproduct of one of its enhanced oil recovery operations. Water Reuse Generates Savings and Enhanced Resilience for Fertilizer Production Facility The Koch fertilizer production plant in Enid, Oklahoma, had a water problem—there wasn't enough, prices were too high, and it needed more. After performing technical evaluations and developing preliminary process designs, Black & Veatch recommended a water treatment system that would receive tertiary wastewater from the city's wastewater treatment plant, treating it for reuse within the fertilizer plant. Oil Company Achieves 99 Percent Sulfur Recovery at Expanded Facility Black & Veatch provided its design leadership to the Onshore Gas Development II (OGD II) project, which involved the addition of a fourth sulfur recovery unit (SRU) to three existing OGD units, plus two new SRUs of higher capacity. Black & Veatch Put the Erdos Xingxing LNG Plant into Capacity Performance in Just 10 Days Erdos Xingxing Energy Co., Ltd. (Erdos) selected Black & Veatch and Chemtex to design and build a liquefied natural gas (LNG) facility in Erdos, Inner Mongolia, China, that produces 200,000 metric tonnes of LNG per year for a variety of fuel uses.
