Oil & Gas

The production and processing of oil and gas will continue to grow in the future, as global demand for energy cannot be met solely by renewable resources in the medium term. In order to use fossil fuels in the most environmentally friendly and energy-efficient way possible, processes such as extraction, refining and finishing (petrochemicals) urgently need to be optimised.

It is to be expected that existing production sites will be modernised, expanded and thus adapted to current requirements and regulations. This also includes the treatment of process wastewater, which must be treated in a much more complex and at the same time more energy-efficient way due to increasingly strict environmental regulations. This can be very challenging for older plants that have already been adapted and enlarged several times. It applies, for example, to the integration of new process stages during operation and, possibly, to limited space conditions. For the oil & gas downstream sector, H+E offers proven and stable processes as well as energy-optimised plants for industrial water and wastewater treatment, from pre-assembled system units to fully operational turnkey plants.

Question

“We will have stricter requirements for the discharge of our wastewater soon, as the limit values according to the German Waste Water Ordinance, Annex 45, will be lowered. What system solutions can you offer us?”

Answer

“For Ruhr Oel GmbH – BP Gelsenkirchen we built a plant with very similar requirements. Because of a decree issued by the Münster Regional Council, the wastewater henceforth had to be treated for direct discharge. Since we have already implemented numerous wastewater treatment plants for the petrochemical industry, the process used guarantees maximum safety and reliable operation of the wastewater treatment plant. We also pay particular attention to its efficiency in the treatment of wastewater and its suitability for use.”

Question

“We need a cost-efficient, reliable and long-term proven ventilation system. Which system can you offer us?”

Answer

“Our AEROFIT®.V aeration system has proven itself for such tasks. Our engineers have developed it for specific application with their typical characteristics. In the case of AEROFIT®.V, these are mainly the oil and gas industry, paper and pulp production, and food and beverage production. This medium-bubble aeration system is characterised by a particularly high oxygen input, long and almost maintenance-free service life, and a wide control range with constant efficiency and without increasing pressure loss.”

Question

“Our production capacity is being expanded. As a result, the volumes of our process water and wastewater as well as their compositions are changing. Our existing treatment plant must be adapted and/or extended - ideally during ongoing operation. What can you do to help us?”

Answer

“At a Shell refinery site in Germany, the processing of inferior crude oil grades, some heavily contaminated with nitrogen and sulphur compounds, together with changed product requirements, led to a higher level of wastewater pollution. This resulted in processing and stability problems in the industrial wastewater treatment plant (WWTP) and thus operational restrictions. Therefore, Shell decided to have its existing WWTP extended by H+E with new deoiling, aerobic high-load, and additional biological denitrification/nitrification stages integrated into the existing plant.”

Question

”Our existing water treatment plant is getting on in years and needs to be modernised or replaced. What can you offer us?”

Answer

“H+E also offers isolated solutions in the field of process and waste water treatment. These include membrane and ion exchanger plants as well as high-performance clarifiers with precipitation and flocculation, primary and/or secondary deoiling in the form of round API oil-water separators and dissolved air flotation systems, biological high-load stages and aeration systems such as our in-house development AEROFIT®.V.”

Question

“Our biological wastewater treatment plant is overloaded regularly/permanently. We are therefore unable to comply with the required limit values. Which process engineering solutions are feasible?”

Answer

“Often operational stability and plant operation can be significantly improved by small optimisations or process extensions. These include: partial flow treatment of a critical process wastewater flow, better or greater equalisation, and buffering to eliminate shock loads. This can also be achieved by a biological high-load stage, a biological selector and an optimised use of chemicals or nutrients. We would be happy to offer you a corresponding study with assessment, or an implementation.”

Question

“We are looking for a competent and expert company that will prepare a concept for a water treatment plant including an inventory, even if the existing plants were not supplied by your company. How can you help us?”

Answer

“Our team of experts will undertake an examination and assessment of your plant – regardless of which supplier it came from originally. One of our specialities is the optimisation of mechanical-chemical and biological treatment stages.”
