Innovative methane purification

ReiCat offers cost-efficient solutions for natural gas purification to ensure high gas quality for all standard applications. Our methane purification plants reliably remove impurities and guarantee a gas purity of 5.0 / > 99.999 % or, if required, 6.0 / > 99.9999 %.

We purify natural gas with minimal operating costs through the modular use of advanced technologies such as catalysts, thermal adsorption, and other process engineering technologies and mechanical processes. Our systems are robust and durable to ensure maximum availability and low maintenance costs.

We offer plants in various size categories and have many years of experience in the construction of large-scale plants.

Manufacturing

We manufacture our systems as skids in collaboration with a broad network of certified and highly specialized suppliers and partners. The most crucial aspect for ReiCat: Quality control!

Quality control is continuously performed during skid manufacturing and between the individual disciplines. ReiCat always carries out both the quality control and the final leak and functional tests.

Commissioning

We support our customers on-site during the commissioning of our systems. This includes supervising the installation of the systems, filling the tanks, performing final mechanical work, and starting up the system.
The skid construction enables quick and safe commissioning.

Maintenance service & spare parts business

Our systems stand for durability. We offer maintenance services to ensure this and supply spare parts, wear parts, and consumables.

Frequently asked questions

What technologies are used for CH4 purification?

Various chemical and mechanical processes are combined to achieve a purity level of > 99.999 %, equivalent to quality 5.0. Usually, more than a single process is required to produce the desired quality.

Depending on the operating parameters, ReiCat Catalyst Technology and TSA (Temperature Swing Adsorption) dryers are typically combined with other chemical and mechanical processes. We often use gas-gas heat exchangers, as catalytic purification requires high temperatures. The gas-gas heat exchangers reduce energy costs through heat recovery (recuperation). Our proven modular system guarantees individual, cost-effective, and high-quality solutions.

Our ReiCat Closed Loop Technology can be installed optionally on any system. It ensures that our CH4 purification systems operate with up to 0 % losses and emissions.

What advantages does natural gas purification from ReiCat offer over other providers?

Our CH4 purification plants are based on a sophisticated modular system that guarantees the highest quality and safety standards.

Zero losses thanks to ReiCat Closed Loop Technology, highly efficient ReiCat Catalyst Technology developed in-house, and the use of few moving parts guarantee low operating and maintenance costs, maximum availability, and long service life for our systems.

We count all major gas producers among our customers and can provide numerous references for methane purification systems.

What service does ReiCat offer for natural gas purification systems?

  1. Remote monitoring: We offer a remote monitoring and maintenance service for high-availability systems to prevent unforeseen but avoidable downtimes.
  2. Maintenance: We offer regular on-site maintenance of your system. This maintenance is carried out by qualified specialists who became familiar with your system during the project planning phase.
  3. Leak tests: We offer professional leak tests for our systems on-site. The tests can also be carried out with annual maintenance or inspection of the entire system. The leakage test is carried out with nitrogen or oil-free air. The detection limit is approx. 1×10^-3 mbar l/s.
  4. Spare parts: We provide a comprehensive spare and wear parts package for every system, ensuring you have all the necessary components. Thanks to our detailed system documentation, essential wear and spare parts can be dispatched quickly.

How is the methane quality measured?

We use redundant online gas analysis devices in our CH4 purification plants to ensure the desired gas quality.

What is the difference between gas purification and gas drying?

At ReiCat, we understand gas drying to mean the removal of moisture from a technical gas. By gas purification, we mean the removal of unwanted impurities from a technical gas. Those unwanted impurities may include moisture. Gas drying is therefore a sub-category of gas purification.
