Steadily increasing demands for environmental protection put increasingly strict requirements on the machines used in the process industry.
The introduction of the CO2 tax and tighter legal regulations in some countries mean that large volumes of H2S and CO2 separated are being injected in refining processes.
LEWA process pumps provide solutions for Carbon capture storage.
Conventional pump systems, such as piston or centrifugal pumps, can be reliably operated for the injection of hydrogen sulfide/carbon dioxide only by using expensive additional measures. Process diaphragm pumps from LEWA are a reliable solution for these pumping tasks up to outputs of 1000 kW. If two coupled pumps running in parallel are used, this extends to well above 1000 kW.
2S (acid gas) is an extreme challenge for pump systems:
It is very toxic, highly flammable and hazardous to the environment
It has poor lubrication properties
It has a high vapor pressure
The most important properties of the LEWA process diaphragm pumps for critical applications such as CCS are:
Hermetically sealed
Previously implemented flows up to 110 m3/h
Dry run safe
High efficiency even in partial load
Diaphragm monitoring system by default
Online and offline condition monitoring systems
Flexibility due to speed control
Variable compositions of material flows and variable back pressures possible
Conveying fluids containing solid content is possible
High operational safety and availability
Long diaphragm service life
Low maintenance costs
Low lifecycle costs
To optimize the energy efficiency in the CSS compression all during the injection a combination of compressors and process diaphragm pumps is recommended.
