The following are examples of a calorie equivalent based comparison of DME CIF price with the price criteria of 2.5 \/Mcal (6.0US$/MMBTU).
Figure 10 shows effects of plant scale on DME price in the range of 500-10000 tons/day. Under the condition of natural gas price of 1.5 US$/MMBTU and transportation distance of 6000km, the scale of 2500
tons/day(0.83 million tons/year production) is required to give DME CIF price in Japan lower than 2.5\/Mcal (6.0US$/MMBTU).

(не очень понятно с этими каллориями)

Figure 11 shows effects of natural gas price and transportation distance on DME price for 10,000 tons/day plant (3.3 million tons/year production). As the plant scale is sufficiently large,DME CIF price is lower than 2.0\/Mcal (5.0US$/MMBTU) with transportation distance of
12000km and natural gas of 1.0 US$/MMBTU. In this case, DME production is feasible to have IRR(Internal Rate of Return) higher than 12%.

Look forward to hearing from you soon,

"Ниже приводятся примеры сравнения цены [поставки] ДЕ [на условиях] CIF в пересчете на калории с ценовым критерием, равным 2,5 иены за мегакалорию ([или] 6,0 долларов США за миллион БТЕ)"

MMBТU - million British thermal units - млн. британских тепловых единиц, ед-ца измерения теплотворности топлива (часто газа), в долларах; в Японии цена в иенах за мегакалорию (тоже ед-ца теплотворности, но в другой системе)
