Sinopec select Siemens for wastewater treatment at Chinese refinery
Warrendale, Pennsylvania, USA, 2011-May-27
Siemens Water Technologies will provide a system to treat wastewater at China Petroleum & Chemical Corporation (Sinopec Corp.)’s Anqing refinery, in Anhui Province, China. The complete wastewater treatment solution will include a powdered activated carbon treatment (PACT) system, a Zimpro wet air regeneration (WAR) hydrothermal unit, and a Hydro-Clear sand filtration system. The three-tier system will be used to treat salty and oily wastewater from refining and petrochemical production activities from existing and upgraded units. The wastewater needs to meet the Chinese specifications for surface discharge. The system will become operational in 2012.
A Siemens wastewater treatment solution, similar to what is at the Anqing refinery, with the aeration tank in the foreground and the WAR system in the background.
The 1,000 m3/h Anqing system will help Sinopec discharge a cleaner effluent and also generate approximately 500 m3/h of reusable water. The refinery will reuse the water in its cooling tower system, which will help to further offset the strain on China’s surface water bodies.
To treat the refinery’s wastewater, Siemens will install a PACT system, which combines biological treatment and carbon adsorption into a single, synergistic treatment step to remove organics. The solids are pumped as slurry to the Zimpro WAR unit where the carbon is regenerated and biological solids are destroyed. As it will generate virtually no sludge that requires landfill disposal or incineration, the WAR system will help to lower operating costs for the Anqing refinery’s wastewater treatment. The Hydro-Clear filter system makes it possible to filter large volumes of water and return it to the cooling circuit, resulting in large savings in the amount of fresh water required and thus further reducing costs. The entire wastewater treatment system’s small footprint design will also reduce land requirements.
The Sinopec refinery discharges its treated wastewater into the Yangtze – the third largest river in the world and the largest in China. Preserving and maintaining this major waterway’s water quality and ecosystems is one of the Chinese government’s main environmental initiatives. Siemens’ approach will help reduce the environmental impact of the treated effluent. The new wastewater treatment system is the seventh project that Siemens Water Technologies has worked on with Sinopec Corp.
Sinopec Corp. is one of the largest crude oil and petrochemical companies in China and Asia. It is also one of the largest gasoline, diesel and jet fuel and other major chemical products producers
and distributors in the region. The principal operations of Sinopec Corp. and its subsidiaries include: exploring, developing, producing and trading crude oil and natural gas; processing crude oil into refined oil products; producing, trading, transporting, distributing and marketing refined oil products; and producing and distributing chemical products.

Here is article on Siemens doing WasteWater treatment for Anqing Coking Refinery for discharge into Yangze River which has become a top Chinese environmental initiative (and become a river that this year has entered China into several modes crisis).
There are things worse than flooding ………………
The Yangze is 3rd largest in world and largest in China – it is also a major domestic barge hub for cargo movements. Conditions on Yangze since February 2011 have been highlighted by the worst drought in over 50 years (opposite problem US has on Mississippi -its Chinese counterpart) with the Honghu Lake in central China also at 1/3 its water surface. Conditions for power and water are severe/crisis mode and as long as they exist China’s largest damn, 3 Georges, will not release water to relieve them (catch 22?).
As mentioned Yangze river is largest, longest (~3900 miles Tibet to Shanghi) and most important shipping route in China. The Yangze River basin is home to ~1/3 of China’s population & accounts for ~40% of Chinese economic growth!
It has been closed to vessel traffic – especially above Wuhan/Hebi and left cargo ships stranded – emergency teams are rescuing grounded ships as we speak and Yangze has left over 400,000 people without drinking water.

season caused the water level along the Yangtze river to be so low

I need give heads up for petcoke market, new projects trying get approval and also get some feedback if anyone has details on outcome of these factors/events?
As follow-up to side angle about the Yangze River drought on Siemens Anqing Coking Wastewater system; I’m wondering how much the two major weather impacts are canceling each other out & why the speculation hasn’t pushed beyond fundamentals for markets and also fuels like coal/coke.
The US is major consumer products and producer of petcoke – the Mississippi is major artery for solid fuels movements and lot petcoke in storage terminals/refinery pads is exposed to contamination/loss from flood incursion. Many of refineries took protective measures which shutdown capacity and all these conditions will last weeks before and after flood peaks are reached.
China is major producer products and consumer of petcoke – the Yangze is major artery for all movements and lot incoming petcoke/coal cannot reach storage terminals/power plants which are not operating due river depth and severe water shortage. Many power & industrial plants are idled/shutdown because of shortage both water and electricity. China’s Huge 3 Georges damn will not release water (meaning it is essentially offline & water is being held reserve) while conditions exist. All these conditions have been going on since Feb and since they were susposed to be in Moonsoon season with relief rains (and are in drought) is likely last weeks/months longer.
These balances remind me of trying track down large error in refinery balance that seems be byproduct of huge factors that cancel each other out – or almost, but create third situation that is real hidden cause for imbalance. The major size and implications for prices across all sorts of Energy, Manufacturing, Trading, Shipping and Terminal markets will be far reaching and beyond past scales of comparison.
Add this onto a fragil US & Global economic recovery and at time when US economy goes flatline going into a pre-election year and stalls out in normal short 6 month recession following election (unless existing president is re-elected that is) ……. and you have big correction in all markets in making and perhaps opening of economic wounds.
