About us

HMJ company was established in 1990. Based on many years of experience in the process industry: chemical, petrochemical, fertilizers; oil&gas, power and aviation, we offer engineering consultancy for medium and large industrial and utility clients in the areas of process analysis, process modelling, power systems modelling, energy efficiency analysis and selection and delivery of process machinery. We use the best industrial software from renowned suppliers for modelling of the process, energy and media flows. We make 3D models of the machinery, plants and whole factories. For years, we have been cooperating with the leading European manufacturers of the industrial process machinery: compressors, turbines, mixers, tanks, motors.

We have references from prime Polish and European industrial Clients.

Process Modelling

Process model is the starting point of each industrial plant or utility. It describes quantitatively and qualitatively transformation of the raw materials, input media and energy, through subsequent phases of semi-products to the output product. In case of chemical processes it involves chemical reactions, change of physical shape, thermal and energy balance. Process-modelling approach is not restricted to the process industry only; this kind of philosophy can be and should be positively used in any industrial or public installation. We use advanced CAPE-software for process flows and balance calculations and propose:

- analysis of the existing process;

- proposition of optimization and changes;

- proposition of new machinery and apparatuses.

Energy Modelling

Linear electric energy model makes possible fast and accurate assessment of the existing factory power grid, with switching stations, generators, power lines, power consumers, electric motors start-up, cable loads, protections, overloads, transients, harmonics, etc., as well as identify hot points and development needs. Upon detailed inventory of the existing grid , we use specialistic software for the grid modelling, both under normal conditions as well as in transient states. Beside balance sheets for electric energy consumption, the model shows critical points, overloads and harmonic constituents carried over to the supplying lines. Electric energy balance, along with thermal energy and media balance, are main input information for assessment of the efficiency of the plant or the whole factory.

3D Modelling

Professional 3D-modelling software as Bentley Open Plant or Solidworks makes possible to execute 3D models with arbitrarily high accuracy of the single components, machines, plants and whole factories. Notwithstanding the big amount of manhours required to produce them, virtual twins of the whole factories, with machinery, material flows, material data, process data – are the future of the industry. Upon request, we present a detailed offer for such model of the industrial plant of any size.

Machinery Modelling

Depending on desired accuracy, we model the casings of the process machines and apparatuses: compressors, turbines, pumps, motors, reactors, boilers, tanks, etc, with main internals: rotors, bearings, sealings, gears as well as material flows and animations of the working movements

Plant Modelling

We model in 3D the installations with foundations, pipings, machines, apparatuses, valves and support structures. The modelling can be done to the schematic level with overall dimensions and weights, or – using previously made 3D models of the individual machines – down to the level of the detail corresponding to the virtual reality.

Factory Modelling

Compositing of individual 3D models of the partial installations with internal transport means as conveyers, roads, walkways, with added terrain shaping, geodetic heights, pipelines and cable lines, buildings and structures we obtain the model of the whole factory or utility accessible for animations, virtual walk-through, view from many cameras, positioning on geodetic maps, relative to GPS points and GIS -models.

Energy Audit

Full Energy Audit of the whole factory contains media balance, thermal balance, electric energy balance as well as effluents released to the environment. The fastest and easiest way to the accurate and credible Energy Audit is through preparing first the Process Model and Energy Model, made on the basis of existing state analysis, with use of specialistic engineering software (CAPE /CAD/Energy). In particular, in case of process industry, the balances must include media other than only water/air/steam/electricity. Comprehensive process model, validated on the existing parameters, makes possible to accurately calculate available savings and propose modernization options. HMJ company, among only a limited number of other engineering houses, is able to execute a complete Energy Audit of the whole industrial factory, applying full-scale process modelling and energy modelling. The Audit is done in conformity to Polish and EU regulations [ Dz.U. 2012 Poz 962 i Dz.U2016 Poz 831] and to the best engineering knowledge and practices. We recommend also to make an Energy Efficiency Assessment for newly planned investments. Detailed technical& commercial offer is submitted upon written inquiry from the Client, based on manhours assessment and to fixed hourly rates. Depending on the size and profile of the Plant ​and required level of detail, the work load is from a few hundred up to several thousand manhours (if 3D modelling is requested). However, our hourly rates belong to the most competitive on the market.
