Refineries are among the major consumers of water that has both process and non-process origins. The average refinery requires 2.5 gallons of water for every gallon of crude oil processed. Depending on the type of crude oil, composition of condensate and treatment processes, the characteristics of refinery wastewater varies widely. The design and operation of modern refinery wastewater treatment plants are challenging and are driven by technology. This article will highlight the most common types of waste streams in a refinery and suitable wastewater treatment strategies.
Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.
Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.
For the unfamiliar, the term “disruptive technology” initially sounds quite bad, as though it describes something that gets in the way. Far from impeding progress, however, disruptive technologies actually accelerate progress exponentially by disrupting the status quo. Think personal computers vs. mainframes, or cell phones vs. land lines.
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
In the oil and gas industry, regulations and requirements to measure, monitor and report flared gases continue to expand and extend. The U.S. EPA continues to focus on enhancing regulations aimed at reducing emissions of methane and volatile organic compounds (VOCs) into the environment.
While the majority of household consumers believe that they deserve the full attention of a water system, from a revenue perspective this does not bear out. Though the average home faucet is undoubtedly valued by its drinking water provider, the reality is that the vast majority of drinking water revenue comes from heavy-use commercial and industrial operations.
Petrogas LLP, one of the world’s largest oil rehabilitation companies, required demineralized water for a new boiler component to its Turkmenistan refinery.
An Oklahoma refinery required a flow meter for a finished product line leaving the refinery site. When the local Siemens representative visited the site, it was determined there simply wasn’t enough straight run of pipe to install the Siemens clamp-on check meter/interface detector that the company had already standardized on.
Upstream oil/gas production companies around the globe depend on mud logging service companies to analyze mud samples that help them maintain the correct direction for their drilling field operations. In mud logging, samples of rock cuttings from bore holes are brought to the surface by recirculating drilling media (mud) for analysis by a mobile laboratory to determine the lithology and fluid content of the sample.
Pumps are all too frequently one of the most overlooked and abused pieces of equipment in process automation, yet nothing moves without them and a process becomes inefficient when they don’t operate properly or completely shutdown.
The Aqua Caiman™ represents the next generation of multi-rake mechanical bar screens. In designing the screen, Parkson combined over 40 years of experience working on thousands of in-channel screen installations with in-depth market and engineering research. This allowed us to better understand the weaknesses of existing multi-rake and articulating rake screens.
This video provides a simple overview of the screen’s creation, function, features and benefits. From the beginning, Parkson engineers took it a step further by working with a leading design firm to rethink the industry standard step style screen from the ground up. They reviewed current offerings on the market and improved upon the common weak points. The result is the most durable escalating screen out there – the Aqua Rhino.
Runoff from farmlands can carry nutrients, insecticides and sediment that impact source water for downstream communities.
Scientists are developing robots that might someday be able to creep through the pitch-black mines to help prevent spills. A 2015 spill from Colorado’s Gold King Mine unleashed 3 million gallons of water that fouled rivers in three states with toxins.
As the popularity of hydraulic fracturing continues to strain available water supplies, a new technology may be the key to recycling produced water in an affordable way.
In the midst of a global water crisis, industries today too often overlook a river of revenue opportunity: their own wastewater.
There is no doubt that the practice of hydraulic fracturing, also known as fracking, has completely changed the oil and gas landscape in recent history. There is also no doubt that this is a highly technical process.
A $15 million federal, solar desalination funding program seeks to foster a world where utilities and industrial operations have easier access to fresh water.
Hydraulic fracturing is a hot-button issue, but no matter where you land you should agree that more efficient produced water filters will go a long way in improving the practice.
A new study led by researchers with Colorado School of Mines exposes limitations with the current methods used to detect chemicals in oilfield wastewater and offers solutions to help regulators make better decisions for managing this waste stream.
A new report from the Academy of Medicine, Engineering and Science of Texas (TAMEST) is shedding more light on what we know and don’t know about the potential health and environmental impacts caused by oil and gas development in Texas.
Researchers at MIT have developed a system that uses visible light to treat produced water, a potential economic and environmental savior for the oil and gas industry.
A new report from the Oklahoma Water Resources Board’s Produced Water Working Group indicates that oil and gas companies looking for ways to dispose of large volumes of wastewater should focus on recycling those liquids within the oil and gas fields, and not use it for irrigation or other surface applications where human and environmental exposure is a risk.
With the change in administration comes a potential paradox for water and wastewater treatment in the oil and gas industry: Will increased production accompanied by decreased regulations call for more treatment technology or less? Either way, the market is poised for change.
As water scarcity continues to be a major, ongoing challenge in the U.S., public and private sector leaders are seeking new insights on sustainable solutions. In this work, they are grappling with challenges on a scale that oil and gas organizations have been confronting for decades now. It’s understandable that stakeholders can get caught up in the tactical side of dealing with water crises — but there is also guidance to be gained by taking a high-level view.
The drop in price of a barrel of oil has had an understandable impact on major projects in the oil and gas industry. Three years ago, with crude trading above $100 a barrel, schedule was the overriding priority. As time delays were equated to lost revenue opportunity, there was less attention paid to the ultimate cost efficiency of a major project.
About 50 percent of the nation’s residents source their fresh water supply from groundwater wells, which have deteriorated throughout the U.S. over the past decade. For shallow wells, severe drought conditions have gradually depleted groundwater levels.
A new generation of electrocoagulation-based water treatment has successfully treated wastewater and effluent from a remote onshore natural gas exploration and production project with over three years of continuous operation. To compound the challenges of treating this wastewater and effluent, the unit was required to operate in an extremely environmentally sensitive environment — a pristine tropical rainforest.
