In environmental chemistry, the chemical oxygen demand (COD) test is commonly used to indirectly measure the amount of organic compounds in water. Most applications of COD determine the amount of organic pollutants found in surface water (e.g. lakes and rivers) or wastewater, making COD a useful measure of water quality. It is expressed in milligrams per liter (mg/L) also referred to as ppm (parts per million), which indicates the mass of oxygen consumed per liter of solution.

Coronavirus and the petrochemicals industry

Article | April 2, 2020

The coronavirus outbreak has touched virtually every aspect of modern life. For the petrochemicals industry, the landscape is shifting at an alarming pace. Only one thing seems certain: the coming decade will be shaped by this crisis. Consumer behaviour, investment decisions, the corporate landscape and even the path of globalisation will be influenced by its effects. Two immediate major shockwaves are linked to economic activity and feedstock pricing. The global economy is heading for recession. Our thinking has moved from an economic slowdown to a deep global recession, with the potential for a slow recovery. This has dramatic implications for the industry.

Transporting biological and chemical materials - what you need to know

Article | February 13, 2020

The landscape of biological and chemical logistics has changed rapidly - as have the regulatory frameworks around it. What has not necessarily kept pace is the end-user understanding of the nature of these logistical processes, their opportunities and their constraints. Twenty years ago, the transmission of biological and chemical materials was limited to a small range of organisations: usually national and international research companies, hospitals, major university departments, police and military departments with forensic responsibilities.

Organic Oil Recovery improves productivity of existing reservoirs

Article | May 10, 2021

MAY 2021 ///Vol 242 No. 5 FEATURES Organic Oil Recovery improves productivity of existing reservoirs A transitional technology producing excellent results in extracting hard-to-reach oil is attracting the attention of many large operators. Ancient, resident microbes are used to liberate large oil deposits in depleted reservoirs, thanks to science uncovered by studying the humble Australian koala. Roger Findlay, Organic Oil Recovery It began in almost outlandish fashion, with a scientist’s fascination with the complex digestive system of an Australian marsupial, the koala. Today, it has evolved into a green technology that is helping major producers around the world potentially reach billions of dollars of oil that they feared they could never access or bring to the surface. As the pressure on the oil and gas industry continues to grow, to find new ways to operate with less impact on the environment, Organic Oil Recovery (OOR) is reducing the need for further exploration. Instead, it is helping producers focus on the reservoirs already in situ to extract even more precious resource—at very low cost—from deep below the ground or seas, across a myriad of jurisdictions and geographies.

Covid-19 Impact on Global Chemical Industry – Initial Analysis

Article | March 25, 2020

Trying to evaluate the impact of Corona virus or Covid-19 on the global chemical industry at this point of time when there is a shutdown in China and other countries is difficult. However, chemical makers both in China and Western countries report progress in their efforts to keep their businesses running in this tough situation. According to Export Genius market research report on global chemical industry, companies with business operations in China are getting their facilities going again, and those dependent on raw materials from China are crossing their fingers even as they reroute supply chains. How COVID-19 has affected chemical industry? Let’s have an initial analysis.
