SIMTO® M-Blend®

SIMTO M-Blend, multiperiod blend recipe optimization, is a solution for product blending, which is a common activity in the process industry and has strong economic and operational impacts. A plant, whether a refinery, petrochemical complex or a blending facility, needs to meet the market's demands and maximize the plant's profits, while utilizing its available materials and equipment to blend feedstocks or products. Examples include:
  • A crude mix needs to make the right product slate and still conforms to the metallurgical limits and capacities of processing units.
  • Gasoline blending involves many blend stocks and additives, stringent quality specifications, and regulatory requirements. Blend stocks vary in quality and quantity from day to day because of variations in the crude mix and unit operation. Quality specifications and regulatory requirements vary by product grades, seasons, and even local markets.
  • A naphtha blend for an ethylene plant needs to have the right aromatic and paraffinic compositions while the contents of poisoning elements remain below their acceptable limits to protect catalysts.
A solution to this wide range of blending applications must be comprehensive, yet flexible, user-friendly and able to work well with other systems. SIMTO M-Blend meets these requirements. It optimizes a blending schedule for a wide range of materials such as crude oil,  gasoline,  diesel,  asphalt,  naphtha feedstock and petrochemical products. It automatically generates optimal blend recipes, while considering component rundown rates and qualities, logistic limitations, and shipment requirements. The optimized solution provides options to help a plant minimize cost and quality giveaway. The program's accurate property blending ensures that the blend products meet their quality specifications and regulatory requirements. The program is also flexible and user-friendly to adapt to the fast-changing paces of the production process and the market. Along with other support systems, SIMTO M-Blend works to provide a plant options to continuously improve its performance for its customers and stakeholders.

Versatile Application

M3 Technology's SIMTO M-Blend tracks the qualities of blend products and tank inventories during the optimization search. The optimizer calculates blend properties, using available blending methods such as indexes, biases, property bonuses, interactions, formulas, and correlations. These blending methods are versatile and adaptable to a wide range of blending applications including reformulated gasoline (RFG), diesel, naphtha, fuel oil, crude oil, asphalt, and petrochemical products. A dynamic blend library is available to handle complex correlations for regulated properties such as VOC, NOx, and TOx. A simulation engine monitors changes in qualities and quantities throughout the blend system and calculates the blend properties, with tank heels if applicable, at the beginning and end of blending activities and at user-defined intervals.
