How to increase steam production under current production conditions while saving energy and reducing consumption

2020-08-05View Original

Thread Content

The 200,000-ton sulfur-based acid production process includes a low-temperature waste heat recovery section. The sulfuric acid storage tank’s volume does not increase; under the current production conditions, how can we increase steam output while saving energy and reducing consumption? I would be grateful for any advice from those with more experience

Let’s discuss methods for saving energy and reducing consumption beyond technical approaches, for reference. Every set of equipment has its own range of applicability, as well as upper and lower limits for its production capacity. It is sufficient to carry out regulation and control within this scope. If it involves controlling powers beyond the normal limits, then one has to rely on equipment, quality, and other factors. In the end, it is necessary to measure the true value of this energy savings in terms of costs. Such as equipment maintenance, wear and tear of spare parts, increased costs for water and electricity, and inability to ensure product quality, etc. I believe that, within the specified capacity limits, maintaining a safe and stable long-term production cycle is the best way to save energy and reduce consumption. There have been improvements to the equipment’s technical specifications and optimizations of the operating procedures, but it is essential to conduct experiments under organized supervision by professional technicians and relevant leaders; once successful, these improvements are incorporated into the operating procedures. It can then be promoted and implemented. However, it is unlikely that the chemical industry will do this solely for energy savings and reduced consumption. Because today’s designers have already taken devices to the limit in terms of energy efficiency and reduced consumption, as this is a competitive advantage in the market. For reference.

A specific analysis of the current status of the equipment and the processes is required. Key points: reduce heat dissipation from the device, ensure good insulation, choose energy-efficient motors, etc.

Increase the gas concentration, thereby raising the temperature of the furnace gas and reducing the heat carried away by air
